Swamp Cooler FAQs

Posted on | by | 7 Comments on Swamp Cooler FAQs

Affordable and energy efficient, swamp coolers are a great way to drop the temperature in your home, without spending the money on a new air conditioner. They don’t use any chemicals or refrigerants, all it needs is water to help you feel cooler.

While this all may sound great, evaporative air coolers are not the right fit for everyone or every home. Only some homeowners will benefit from using a swamp cooler inside their home, and even then, it is hardly ever a suitable alternative to other types of air conditioners.

What Is A Swamp Cooler?

A swamp cooler is an appliance that uses the evaporation of water to help cool the air stream and add humidity back into the air. They are particularly useful for anyone living in arid climates.

Other names for these devices include:

  • Evaporative coolers
  • Wet air coolers
  • Desert coolers

How Does A Swamp Cooler Work?

This type of air cooler utilizes the principles of evaporative cooling.

A swamp cooler is really just a simple contraption that uses a fan to suck in hot air, typically from the outdoors, then pushing the air over a number of wet “cooling” pads.

As the hot air passes over these pads, the liquid water turns into vapor, which is then pushed out of the unit, and into the air inside your home. Once the vapor starts to circulate into the air, the added moisture will extract the heat from the air, helping the ambient temperature feel cooler.

How An Evaporative Cooler Works

The dry air temperature cools during the evaporation process. This is the same method that the human body uses to cool itself down. When we get hot we sweat and the sweat evaporates which lowers our body’s temperature.

Because of this it’s important to use only in hot, dry climates. For optimal performance, only homeowners that have humidity levels below 50% should use a swamp cooler inside their home.

Back to all FAQs



Does It Lower the Ambient Temperature?

A swamp cooler will help make the temperature feel approximately 5°-15° lower in the area within close proximity to where it is located. However, they will not lower the overall ambient temperature in the room.

This is a common misconception and important for homeowners to understand prior to purchasing an evaporative cooler. Unlike an AC unit, you will not feel a significant drop in temperature, nor will you be able to control the temperature with any sort of precision.

Back to all FAQs

What’s the Difference Between a Swamp Cooler & Air Conditioner?

The most notable difference is the method in which they each cool the air that is being circulated within the room.

An air cooler uses water, cooling pads and an internal fan to increase the humidity within the room, whereas an air conditioner uses a compressor and refrigerants that can rapidly cool the air.

While they may have similarities and are both intended to cool a room, it’s very important to understand that they each utilize a distinct cooling method and are not a one-for-one replacement.

Portable Cooling Confusion

The similarities are noticeably obvious when it comes to portable air conditioners. Because of how similar they are in shape, size and design, not to mention they each have “portable” in their name, it’s very common for homeowners to confuse these units with portable evaporative coolers.

Unfortunately, they operate very differently, and this has left plenty of homeowners both confused and disappointed with their purchase.

Back to all FAQs



What’s the Difference Between an Evaporative Cooler & Air Fan?

A fan uses rotating blades to create a current of air but has no real effect on the temperature or humidity within the room. All it does is circulate the air around you. It may feel cooler when you first feel the air circulating around you, but this is due to the “wind chill effect” that it creates and will be temporary, at best.

Whereas, an evaporative cooler utilizes an internal fan to help circulate air, but also goes one step further by using a set of wet cooling pads to help recreate the evaporation process by adding a bit of moisture to the air.

Back to all FAQs

What is the Best Environment to Use a Swamp Cooler?

Due to the evaporative nature of how they operate, swamp coolers are best used in hot, dry climates where the temperature is high, and the humidity levels are low.

Back to all FAQs

Can I Use One If I Live In A Humid Climate?

This is not recommended. If your home is located in an area with a humid climate, then it would be unwise to use a swamp cooler inside your home.

Not only will they be ineffective at cooling, but they will just add unnecessary amounts of moisture to the air. As a result, the excessive humidity levels inside your home will cause more issues and lead to poor indoor air quality.

If you live a humid climate, the better choice would be to use an air conditioner for cooling the interior of your home. However, depending on your location and the fluctuating temperature, there may be certain times in the day that you could use a swamp cooler to help supplement your air conditioner.

Back to all FAQs



Will a Swamp Cooler Help Cool a Garage or Workshop?

Yes. An evaporative air cooler can be a great choice for cooling your garage or workshop. Due to the large doors and poor insulation, you are less-likely to experience the negative effects of too much humidity.

Ironically, it’s because of these same reasons that garages often don’t have an air conditioner. As a result, a swamp cooler could be the ideal choice to provide cooler airflow, especially on those hot summer days.

Back to all FAQs

What Size Swamp Cooler Do I Need?

Once you’ve made the decision to purchase an air cooler, you need to determine the right size unit. Air coolers are measured by cubic feet per minute (CFM). This is the measurement used to determine the amount of air that will be circulated each minute.

How to Calculate CFM:

Figuring out the CFM is pretty easy and shouldn’t take more than a couple of minutes. Here’s the steps you will take.

  1. Determine the square footage of the room.
  2. Multiply the room’s square footage by the height of the ceilings.
  3. Then divide that number by 2.
  4. This is your suggested CFM for that room.

For Example:

To illustrate how this works, we’ll be calculating the amount of CFM needed to cool a room with 150 square feet and 9ft. tall ceilings.

  • Room Sq. Ft — 150 square feet
  • Ceiling Height — 9 ft
  • 150 x 9 = 1350 / 2 = 675 CFM

In the example above, I would need to find a unit that has a minimum of 675 CFM.

If the CFM falls in between units or you have an odd-shaped room with lots of corners, you would want to purchase an air cooler that is slightly larger. If it is too small will have to worker harder to keep the area cool and waste energy doing so.

Back to all FAQs

How Do You Clean A Swamp Cooler?

A swamp cooler will follow a similar cleaning process as a humidifier. Any part of the device that gets wet, needs to be cleaned and sanitized on a regular basis.

To ensure proper cooling and the prevention of mold or mildew, the tank and cooling pads should be cleaned with soap and water at least once every 7-10 days. Allow all parts to dry thoroughly.

This will prevent dust, dirt, and mildew from building up. Cleaning the unit regularly is especially important if you are using the air cooler for long periods of time.

External – Cleaning the outside of the air cooler can be done periodically by simply wiping it down with a damp cloth.

Back to all FAQs



How Often Do You Refill the Tank?

This depends on many factors, ranging from how you are using the device to the brand/model itself. Generally speaking, you should not have to refill the tank for at least 4-6 hours.

Refilling Swamp Cooler Tank

Below, are a few considerations that will play a role in how long your tank will last before it needs to be refilled.

  • How big is the device?
  • How / where often are you using it?
  • What is the temperature of the room / surrounding area?
  • What is the relative humidity of the room / surrounding area?
  • What is the insulation like in the room it is being used in?

Depending on how you answered the above questions, you to help you determine whether or not you can use your swamp cooler in a more efficient manner.

Back to all FAQs

How Often Do You Replace the Cooling Pads?

This depends on how you are using and caring for the device. If you clean your swamp cooler on a regular basis, then your cooling pads will last for quite a while.

As the summer season sets in and you prepare to use the evaporative cooler for the first time, inspect the pads to make sure that they have no damage. If you notice any cracks, then they will need to be replaced.

  2. Does Carbon Monoxide Smell?
  3. What Causes Carbon Monoxide in a House?
  4. How Does a CO Detector Work?
  5. Where to Install CO Detector?

Nicknamed the “Silent Killer,” carbon monoxide is more common in homes than you may think. In fact, it’s likely in your home right now as you read this.

Should you be concerned by its presence? And, what can you do about it?

Let’s take a look at some of the most common questions homeowners have about carbon monoxide, and why you should have a CO detector in your home.

What is Carbon Monoxide?

A toxic gas that has no visible appearance or noticeable odor, carbon monoxide (CO) can pose serious health risks when it accumulates beyond a certain level.

Because it is completely indiscernible to the human senses, detecting it can pose a bit of a challenge for homeowners. It’s important to note that carbon monoxide is constantly present within your indoor air, but poses little risk until it hits a certain threshold.

Does Carbon Monoxide Smell?

No. You cannot smell carbon monoxide. Nor can you see, taste or otherwise notice its presence unless you have the right equipment.

Carbon Monoxide

It is precisely because of its inconspicuous nature that CO has earned the nickname as being a “Silent Killer” or “Invisible Killer.”

Sadly, unless you have the a carbon monoxide detector installed in your home, you won’t know that levels have reached a toxic level until it is too late.

What Causes Carbon Monoxide in a House?

The short answer is that CO can originate from anything that burns fuel for power. This can include everything from automobiles to gas-powered stove ranges, even water heaters and fireplaces. Carbon monoxide occurs as result of partial oxidation of compounds which contain carbon, forming when insufficient oxygen exists to produce carbon dioxide.

An average home will usually contain up to 5 ppm of CO in the air at any given time, a level that is near to the natural atmospheric concentration and is safe for people and animals to breathe. If you have a gas stove in your home, the level may be slightly higher, but still not high enough to cause significant health concerns.

However, problems with appliances or inadequate ventilation can cause carbon monoxide to collect in parts of a home, eventually elevating to levels where it may be unsafe to remain inside.




How Does a CO Detector Work?

A carbon monoxide detector works much like a typical smoke detector. Equipped with built-in sensors that can identify and measure the concentration of CO in the air.

When unsafe levels of CO are discovered, the device will broadcast an alarm that will alert the occupants inside the home. In theory, this would give anyone within the immediate area an opportunity to respond quickly in order to avoid overexposure to the gas.

Carbon Monoxide Detector

Where Should I Install My CO Detector?

While there are many factors to consider, it is important to pay particularly close attention to what the manufacturer states is best for that specific model. Within the user manual, you will find all the information you need to install it in your home.

Determining the Best Placement:

Aside from the manufacturer’s recommendations, there are a few general guidelines that can help you determine the best placement of a CO detector within your home.

  • Inside Bedrooms — It’s wise to have a carbon monoxide detector in all your bedrooms or any other area of your home where occupants may fall asleep.
  • Central Locations — Spread evenly throughout your home, you should place a CO detector on all levels near any main rooms where residents may be found, including your living room, dining room and near doorways that lead into a garage.
  • Unobstructed Areas — Wherever you install your carbon monoxide detector, make sure that you do not place it anywhere that may be blocked by furniture, drapes or other objects.
Where to Install CO Detector in Home

Just like you would with smoke detectors, it’s wise for homeowners to install these near any potential sources of carbon monoxide output or areas where it may accumulate.

Is Carbon Monoxide Heavier Than Air?

No. Carbon monoxide is lighter than air. Apparently, there is much debate surrounding this question, which has lead to further confusion about where homeowners should install a CO detector.

Hopefully, this 2012 study published in The Journal of Emergency Medicine will settle the debate and give homeowners some reassurance about the location they decide to install their unit. Researchers came to the following conclusions:

CO did not layer on the floor, float at the middle of the chamber, or rise to the top… Mixing would be even faster in the home environment, with drafts due to motion or temperature. It would be reasonable to place a residential CO alarm at any height within the room.

What Are the Symptoms of CO Poisoning?

Any exposure to CO can be potentially dangerous. It is because of this that every homeowner should take any necessary precautions to protect their family and ensure that the air inside their home is safe.

Call for Help!

American Association of Poison Control Centers
1-800-222-1222

For the majority of homeowners, it is unlikely that minimal exposure will cause any issues, however, this is still a toxic gas that has no health benefits associated with it. If you have babies, young children or small pets in your home, you should be especially mindful of how much CO is in your air.

Symptoms may include the following:
  • Respiratory issues.
  • Fatigue and weakness.
  • Headaches, ranging from dull to severe.
  • Dizziness, nausea and vomiting.
  • Impaired judgement and sense of confusion.
  • Faintness and loss of consciousness.
Symptoms, Safe Levels & Duration of Exposure:

While the actual duration and concentration amounts may vary, below is a general guide to help homeowners learn what symptoms they may experience when exposed to different levels of this poisonous gas.

  • Constant exposure to a CO concentration of 35 ppm for 6-8 hours can result in headaches and dizziness.
  • Exposure to 100 ppm can result in headache symptoms in just 2-3 hours.
  • Exposure to 200 ppm may produce headaches and impaired judgment within 2-3 hours.
  • With exposure to 400 ppm, more severe frontal headaches can occur in 1-2 hours.
  • 800 ppm of CO concentration can lead to nausea, dizziness, and convulsions within 45 minutes.
  • 1,600 ppm concentration levels will produce the above symptoms in just 15-20 minutes, and can cause death within 2 hours.
  • Concentration levels greater than 3,200 ppm will cause severe symptoms in 5-10 minutes, and death within a half-hour.
  • As levels increase above 10,000 ppm, unconsciousness will occur after just a few breaths. A full-grown adult will not be able to survive more than a few moments of such exposure before death occurs.

Note: If you believe you or your family is in any sort of danger, get out of the house immediately. Call 911. Call poison control at 1-800-222-1222.




How Can I Protect My Family From CO Poisoning?

No matter how large or small your home may be, there are several ways that a homeowner can prevent and protect their family from this poisonous gas.

Carbon Monoxide in Your Home

  • Install New CO Detector:

    Install a new carbon monoxide detector that meets all current requirements of UL 2034 safety standards. It is suggested that you install at least one detector for each level of a multi-story home, and one unit near each separate sleeping area of a home and/or near locations where gas might collect (such as near a garage).

  • Proper Installation & Maintenance of Fuel-Burning Appliances:

    Ensure that fuel-burning appliances are properly installed and maintained per manufacturer’s instructions, and with respect to local building codes. Professional inspections and servicing of heating systems and chimneys should be performed annually. Never attempt to complete repairs or servicing without qualified knowledge and proper equipment.

  • Never Use Gas-Powered Engines Inside:

    Never operate generators or tools with gas-powered engines indoors, including in garages. Even with doors and windows open, enclosed spaces can trap CO and allow it to quickly accumulate to dangerous levels. Never leave cars running in an attached garage, even with the door fully opened.

  • Never Use Gas-Powered Heaters Inside:

    Do not heat your home using gas-powered appliances such as ovens or ranges, and never operate fuel-burning appliances in unvented rooms where people are asleep.

  • Ensure Chimney is Clear & Unobstructed:

    If performing renovations or repairs on your home, be sure that chimneys and appliance vents remain unobstructed. Verify that all such appliances are in good working condition after work has been completed.

The Best Resources For Homeowners

As your install a CO alarm in your home, take a few minutes to familiarize yourself with the resources listed below. While it is unlikely that you’ll experience an issue, especially now that you have the right equipment to alert you, it is still wise to know what to do if needed.

What is a Portable Ice Maker?

A portable ice maker is a small appliance that is designed to make ice, but doesn’t require permanent installation or a dedicated water line. You can plug it in and make ice at your convenience, or store it out of the way when you don’t need it.
Back to all FAQs

How does a portable ice machine work?

Portable ice makers operate by quickly making small batches of ice from water that you pour into the unit. Once a batch is ready to serve, the machine will drop the ice down onto the tray for you to scoop out when needed. Simply plug it in, pour in some water and you’ll have ice within a few minutes.

However, unlike other types of ice makers, portable units don’t have a drain, so as the ice begins to melt, the water simply drips back down into the basin whereupon it is turned back into ice.

The cycle repeats until there is no more water in the ice maker.

Back to all FAQs

How do you clean a portable ice maker?

Cleaning your portable ice maker is a simple task, and just about the only maintenance needed to keep it operating in an efficient manner.

Portable Ice Maker

Every ice maker will have their own specific cleaning instructions in the manual that came with the device. You may also be able to download them from the manufacturer’s website.

If you don’t have access to the cleaning instructions for your specific model, you can follow these steps:

  1. Unplug the ice machine.
  2. Empty all water or ice.
  3. Disassemble interior pieces and wash separately.
  4. Clean the interior with a towel.
  5. Pour a generous amount of vinegar into the unit with some water.
  6. Allow device to run a few cycles and discard all ice with vinegar.
  7. Allow machine to dry before using.
  8. Add fresh water and enjoy.

Note: You can substitute vinegar with a cleanser made for ice machines.

Back to all FAQs

How long does it take to make ice?

This will vary between different models, but generally, a portable ice maker will produce ice within 7-15 minutes after you add water.

It’s important to note that there are a few other variables that can play a role in slowing down production of an ice maker.

  • The type of water you use.
  • How often you clean the ice maker.
  • The age of the ice machine.
  • Frequency of use.

If you use hard water and don’t clean your ice maker on a frequent basis, then it is likely that mineral build-up will start to happen inside the device. This will slow down production time and quality.

Back to all FAQs



Do portable ice makers need a dedicated water line?

No. A portable ice maker does not need or even require a dedicated water line to work. As the name suggests, this appliance is designed to be portable, allowing you to plug it in when and wherever you need it.

When you want it to produce ice, you simply plug it into an outlet and fill the reservoir with water. The unit will start producing ice relatively quickly.

This lack of a water line is one of the main differences that sets a portable ice maker apart from other types of ice machines. This may be considered both an advantage and disadvantage, depending on how you plan on using it.

Back to all FAQs

Do portable ice makers need a dedicated drain line?

No. A portable ice maker does not need or require a dedicated drain line to operate. Much like a dedicated water line, a built-in drain line would make it less portable.

Due to how this type of ice machine works, it has no need for a drain line. As the ice melts, the water goes back down into the basin where the machine turns it back into ice. This process repeats until you have consumed all the ice, or add more water.

Note: To ensure that your ice is fresh and tasty, it would be wise to drain any water that has been sitting in the unit for more than a day.

Back to all FAQs

Does it matter what type of water I use?

Yes, to some extent. The overall quality of the ice produced by the machine is largely determined by the quality of the water you pour into it. But, the type of water you add to the unit can also play a role in its ability to produce ice, how often you have to clean the unit, and its overall lifespan.

Obviously, the water should be potable. If it’s not safe to drink, then there’s no reason it should be inside an ice machine. But outside of whether it’s safe to consume, determining the “best” type of water is going to be subjective.

  • Hard Water — Generally, it would be wise to avoid “hard water,” as it will eventually lead to mineral build-up inside your ice machine and diminish the quality of ice that is produced. This applies to all appliances.
  • Distilled Water — While this type of water has less minerals, it may also cause performance issues with some ice makers. This is due to the usage of sensors inside most portable ice machines that rely on mineral content to determine whether more ice needs to be made.
  • Filtered & Purified Water — These fall somewhere in the middle. The mineral content will be lower than hard water, but not low enough that the sensors inside are unable to perform their duty. The water quality is usually better, which means you should get ice that smells and tastes fresh.

With all of that said, the best type of water should always come down to the experience you get from the ice.

Back to all FAQs

How does ice production differ from ice storage?

Often overlooked, the product/storage capacity are two considerations that one must take into account before buying any type of ice maker. All manufacturers will have these listed somewhere in their spec sheet.

  • Storage — This defines the maximum amount of ice the unit can have ready to serve.
  • Production — This defines the maximum amount of ice the unit can produce in a day.

This is also another major difference between portable ice makers and other types available. Because they are designed to take with you on-the-go, portable units will be significantly lower in both capacities.

Back to all FAQs

Is a portable ice maker a freezer?

No. This type of ice machine is not a freezer, nor is it a suitable alternative to a freezer.

While the design will vary from model to model, all portable ice makers have an insulated exterior to help keep the ice frozen and ready to consume. However, there are no portable machines that double as a freezer. This means that the ice will slowly start to melt the moment it hits the tray.

Once it melts, the water goes back down into the basin where it is used to make another batch of ice.

Back to all FAQs

How much electricity does a portable ice maker use?

Like all appliances, the amount of electricity will differ between brands and models, as well as how you are using the device and the frequency you clean it.

Countertop Ice Maker

For the most part, portable ice makers are not known to be very energy efficient. We are unable to find any portable ice makers that are EnergyStar certified.

However, that doesn’t mean that they are going to cost a lot to run. In fact, they use far less electricity than undercounter ice machines or refrigerators with an ice maker built-in. And if you only plug it in when you need ice, then it is very unlikely that you’ll notice any increase in your utility bills.

For more insight, we would encourage you to read this article from Wired Mag where they analyze, calculate and estimate precisely how much it would cost to use an ice machine.

Back to all FAQs

Do these work with standard 120v wall outlets?

Yes. All portable ice machines will work with a typical 120v wall outlet commonly found in homes and offices. You should not need any other equipment to make ice.

Back to all FAQs

What do I need to do before using the ice maker?

Once you unbox your portable ice maker, it is recommended that you make a few batches of ice and discard it. This will remove any possible dust or debris that may have gather inside the unit during packaging or shipping.

Back to all FAQs

Who makes the best countertop ice maker?

We try to stay impartial when it comes to brands. Certainly, some brands are going to be more reputable than others, just based on how long they’ve been manufacturing this type of product. Of course, this is not an indication of a “better” brand, but does offer a glimpse at how reputable a company is.

To help you determine which brand is best for you, make sure you look over the warranty that comes with the product, as well as the return policy from where you purchased it. Also, take some time to read over some reviews that customers have left. While the reviews are never going to be an accurate assessment of the brand, you may gain more perspective of what to expect from that brands’ customer service.

Back to all FAQs

What is the best portable ice maker?

There is no correct answer to this question. The best portable ice maker is going to depend on your needs. And for many homeowners, a portable ice maker may not even be the best fit for them.

To find the best portable ice maker, you should do careful research on the brands and models available within your budget, and then compare their features to narrow down the one you deem to be the best unit for you.

Back to all FAQs

Where can you buy a portable ice maker?

You can buy portable ice maker from a wide variety of retailers, both online or in stores. You’ll find that you have a better selection online.

Before you buy a portable ice machine at Walmart or Home Depot, we would recommend browsing your options online and narrowing down which model would be best for your home. You don’t have to buy online, but you’ll at least have comfort in knowing that you made an educated buying decision.

What is a Portable Air Conditioner?

Designed to be moved from room to room with ease, a portable air conditioning unit is a smaller cooling appliance that vents directly out of your window, but doesn’t require permanent installation.

Generally, this type of air conditioner is engineered to cool individual rooms, not your entire home. To make it easier to move around, portable units often have wheels on the bottom and built-in handles on the side.

Portable Air Conditioner

Do portable room air conditioners work?

Yes, of course. They are a popular alternative to central air conditioners, and one of the better choices for cooling rooms in your home.

Of course, the amount of benefits you receive from a portable air conditioner is entirely dependent on how you use, how well you maintain it, the environment you are using it in, and a whole host of other factors. But, yes, portable air conditioners do work when used correctly.

Back to all FAQs

Are these air conditioners energy efficient?

It depends on how you use it. When compared to other types of air conditioners, portable units are going to be one of the worst for energy efficiency.

Across the board, portable units tend to have a lower Energy Efficiency Rating (EER) than other air conditioners. The overall efficiency will vary per each model or brand, and you certainly will find some units that have a higher EER than others, but for the most part, this appliance is not considered as one that is energy efficient.

However, they do have the advantage of allowing you to cool only one room at a time. This cooling strategy will help you save money and cut your overall energy usage, as you’re not having to pay to cool your entire home. From this perspective, one could absolutely make the case that it is energy efficient.

Back to all FAQs

Do all portable air conditioners need to be vented?

Yes. You will need to vent your air conditioner. This is typically done through a window, but you can also buy a vent kit that works with sliding glass doors, casement/crank windows or through a dropped ceiling.

Most portable air conditioners will come with everything you need to properly vent the device, including an exhaust hose and an adapter that sits in your window sill. Just remember to follow the instructions for the model.

Back to all FAQs



What is a window vent kit?

The window vent kit will come with your portable air conditioner. Typically made from plastic, this is the piece of equipment that sits in your window sill and connects to your exhaust hose(s) of the AC unit.

The window venting kit will typically fit most standard-sized windows and sliding glass doors. However, before you buy a portable air conditioner it would be wise to measure the window and ensure the venting kit that comes with the AC unit will fit in your home.

There are many venting kits available online, including many designed for larger windows and casement windows.

Back to all FAQs

What if I can’t vent the AC unit?

That would be unfortunate. If you are unable to properly vent your AC unit, then this type of air conditioner will not be a sufficient cooling option for your home. You would want to consider an evaporative cooler.

Portable air conditioners work by moving hot air out of the room, so if you’re unable to use a vent, then the machine will not cool your room in an efficient or effective manner. You may feel some cooling if you are directly in front of the unit, but you’ll also notice some ambient heat building from the back.

Can I vent a portable AC through a dryer vent?

Sure, it’s possible. But, it’s probably not the best idea. This is definitely not a good idea if the diameter of the hose doesn’t fit the diameter of your dryer vent. Unfortunately, this is often the case, as many dryer vents in American homes have a diameter of 4 inches, and most portable air conditioners come with a larger vent hose.

If the diameters of the hose and dryer vent are the same diameter, you could attempt to vent your portable air conditioner in this manner. But, again, it’s not recommended and may lead to other problems. So, if you do attempt this, keep a close eye on the device until you feel confident that it is venting appropriately.

How long is the exhaust hose?

It varies. The hose or duct that comes with your portable air conditioner will vary from model to model, but they typically are at least 3-4 ft. in length.

Portable Air Conditioning Unit

You can buy longer (or shorter ones) at many retailers. While it is generally recommended that you buy a longer exhaust hose from the same brand or retailer that you bought your AC unit, this is oftentimes unnecessary.

However, it is important to understand that the longer you make the exhaust hose, the less efficient your air conditioner will be. This may also lead to your unit having to work harder to cool the room, which may cause the compressor to work harder than it should possibly shortening the lifespan of the air conditioner itself.

It would be wise to keep the exhaust hose shorter than 10 ft, unless you also have an exhaust fan of some sort that will help the hot air escape and allow your portable air conditioner to work in a more efficient manner.

Back to all FAQs

Can I make my own exhaust hose?

Sure, but it’s not recommended. There are many scenarios in which a homeowner may desire a longer exhaust hose for their portable air conditioner. Unfortunately, the longer the exhaust hose, the less efficient the AC unit becomes.

If you want to replace the exhaust hose, it is best to buy one that is designed for this type of air conditioner, but if you’re in a bind or feeling handy, you can purchase many of the necessary materials at a hardware store, such as Home Depot or Lowes.

Keep in Mind: If you go this route, make sure the replacement hose is the same diameter as the previous hose or the venting duct in the back of the unit. Most portable air conditioners have a 5 inch hose, but not always. Double-check before you buy. You could also consider using a PVC pipe, but that, too, comes with many disadvantages.

Back to all FAQs

What’s the difference between a single-hose and dual-hose unit?

The way the air moves in and out of the device. Choose a dual-hose, if possible.

  • Single Hose — All air comes in and vents out of the one hose.
  • Dual Hose — One hose is used to pull in air from outside, and the other hose is used as an exhaust.

Dual-hose portable air conditioners are considered to be the better of the two options, as it is more efficient and can cool your living space quicker than single-hose units.

Back to all FAQs

Do portable air conditioners give off carbon monoxide?

No. Because it runs on electricity, you do not have to worry about a portable air conditioner emitting carbon monoxide into your home.

In extreme circumstances, it is possible for a portable or window air conditioner to pull in air from the outside that is high in carbon monoxide. This is possible when a fuel-burning device is directly on the other side of the window. These may include a running car, portable generator or a grill you may be cooking on.

Again, this is an extreme scenario and it is unlikely that a portable AC will pull in enough carbon monoxide for you to experience negative symptoms. But, just in case, it would be wise to know what is going on near the vent, as well as have a carbon monoxide detector in your home.

Back to all FAQs

Is a portable AC the same thing as an evaporative cooler?

No. These are two very different cooling appliances, and not an ideal substitute for each other.

An evaporative cooler, sometimes called a swamp cooler, uses water and the process of evaporative cooling to help make the temperature of the room feel cooler. Unlike portable air conditioners, you have to add water to an evaporative cooler for it to work, and it does not require any sort of ventilation. These are great for garages and workshops.

Back to all FAQs

How loud are portable air conditioners?

It depends on the model you buy. Like most appliances in your home, the amount of noise (or the decibel level of the device) will depend entirely on the model itself.

All types of room air conditioners will emit some level of noise, with some being louder than others. Most homeowners consider this as background noise or white noise, much like your refrigerator or dishwasher.

Unfortunately, decibel ratings are not a spec that manufacturers advertise for portable air conditioners. To get a better idea of how noisy a particular model may be, you will have to read over reviews for each unit and try to make an educated decision for yourself.

Back to all FAQs

Can you soundproof a portable air conditioner?

Not really, but you can take steps to lower the noise. If you buy a portable AC and find it to be loud, you can take a few steps to lower the noise.

  • Softer Surface — Take a look at the surfaces the AC unit is sitting on. If you have it positioned on a hard floor, then you should try to put a small rug underneath the unit. This will help lower the amount of vibration of the compressor and internal fans, and help make it a little more quieter.
  • Change the Fan Speed — It’s also important to note that the decibel level will likely change depending on the fan speed that the device is currently operating on. If it is operating on the highest speed, you will likely hear a little more noise.

Again, the above steps can help you soundproof it, but you will never be able fully eliminate the sound a portable air conditioner makes while it is operating.

Back to all FAQs

What type of electricity do portable air conditioners use?

For typical residential use, portable air conditioners only need to be plugged into a standard electrical receptacle found throughout your home. You will not need any extra power or a special wiring setup to use this type of air conditioner.

The only time you may need a special plug or a dedicated circuit for operation, is for large commercial-sized air conditioners.

Back to all FAQs

Can you use it to cool multiple rooms at the same time?

This depends on a few factors, but is certainly possible. These include the environment in which the air conditioner is being used, how well the air is circulated in this area, and the BTU rating of the device itself.

As an example, if your living space is very open and you’re using a high-BTU unit, then you may feel a cooling effect throughout the entire space. However, if you have a lower-BTU rating and the space is contained with lots of doors and walls, the device will have trouble cooling all areas in an effective manner.

To help you cool larger rooms, consider using a small fan near the air conditioner to help the cold air reach far corners of the space.

Back to all FAQs

Will these AC units work for garages?

Not really, at least not very efficiently.

You can use them pretty much anywhere there is a plug, including inside your garage or workshop. Unfortunately, if your garage door is wide open or the area is not well-insulated, then it is unlikely that you will feel the temperature drop.

To cool your garage, you should consider using an evaporative / swamp cooler.

Back to all FAQs

Will these AC units work for server rooms?

Absolutely! In fact, cooling a server room is one of the most common uses for a portable air conditioner.

Due to the heat that servers generate, especially when clustered together in a small room, it is crucial for you to keep them cool in order for them to operate in an efficient manner. Because of this, portable AC units are often used in conjunction with a central air conditioner to help cool the room with the computer equipment.

If you have a small server room in your home or small business, you may have buy a special vent kit or longer exhaust hose to properly vent the AC unit.

Back to all FAQs

Is a portable air conditioner the best choice for me?

It depends on your situation. This type of air conditioner is great for anyone that wants to cool one room or area of their home, but is unable to do so with a window unit.

Ask yourself these questions:
  • Do you want to have a window A/C unit sticking out from your home? If not, then you should go with a portable unit.
  • Do you live in an area with a zealous Homeowner’s Association? If so, then they’ll likely have rules in place to prevent window units, therefore leaving a portable air conditioner as the best choice.
  • Do you care about your energy usage of a room air conditioner? If so, then a window unit is going to be the best choice for you.
  • Are you capable of installing a window unit? If not, then perhaps you skip the hassle and go with a portable AC.

Keep in mind, a portable air conditioner is a popular cooling option used in millions of homes around the world, but they certainly comes with their own set of pros and cons. If you do your research and make an educated buying decision, you’ll be happy with your choice.

Back to all FAQs

Where can I buy a portable air conditioner?

You can buy portable air conditioners from a wide variety of retailers, both online or in stores.

Before you buy a portable air conditioner at Walmart or Home Depot, we would recommend browsing your options online and narrowing down which model would be best for your home. You don’t have to buy online, but you’ll at least have comfort in knowing that you made an educated buying decision.

What is a garbage disposal?

A garbage disposal is a motorized appliance installed underneath your sink that allows you to finely grind food waste into small particles that can be safely disposed of down your drain.

Common names include:

  • Waste disposal unit
  • Garbage disposer
  • Garburator
  • Insinkerator (popular brand)
Back to all FAQs

How do garbage disposals work?

A garbage disposal is really just a simple demonstration of Isaac Newton’s laws of motion.

Garbage Disposal Diagram

The moment you turn on your disposal, a small plate at the bottom of the “grinding chamber” starts to rotate at high velocity.

On this plate, you will find two impellers. These are essential components, as they help create the necessary centrifugal force that propels the scraps of food against the internal wall of the chamber. This wall grinds the food down into tiny particles that can flow down the drain.

Contrary to popular belief, most homeowners believe that a garbage disposal works much like a blender. While they indeed have many similarities, this is factually incorrect. There is no chopping, cutting or chewing involved in the process. In fact, a garbage disposal doesn’t even have blades!

This animation provides a great visual explanation of how a disposal works.

Back to all FAQs

What size garbage disposal do I need?

This is a question with an impossible answer. Every homeowner will have different needs based on their unique situation.

To find the right size disposal for your home, you should first consider how much power you will need. This can be determined by considering a few factors.

  • How many people live in your home?
  • How often will you be using the disposal?
  • What kind of food do you currently prepare, and how much waste does it create?

Common Sizes:

  • 1/3 horsepower
  • 1/2 horsepower
  • 3/4 horsepower
  • 1 horsepower
  • 2+ horsepower

Generally, the more people in your home, the more often you’ll be using the disposal, thus the more power (or larger size) you’ll need.

However, you should also consider the types of food waste that you’ll be putting in the disposal, as well as the volume you think you’ll create.

Note: When it comes to garbage disposals, the term “size” refers to power, not the actual dimensions of the unit. Another important consideration, but one that is unlikely to affect your buying decision, but does play a role in the installation.

Back to all FAQs

What items can you put in garbage disposal?

This is a great question that more homeowners should be asking. A common misconception is that anything and everything can go down a garbage disposal. In reality, there are a number of items that should never be put down a disposal. This includes the scraps of many popular foods.




Never put these in disposal:

  • Cooking oil / grease
  • Stringy fruits and veggies
  • Pasta
  • Rice
  • Beans
  • Coffee grounds
  • Eggshells

Note: If you have a large, powerful garbage disposal from a reputable brand, then some of the items listed above would likely be okay to put into the unit. However, to prevent possible problems and ensure your garbage disposal has the longest life, it is recommended that you avoid the items above.

Back to all FAQs

Why does my disposal smell?

There is likely food waste inside the grinding chamber that is starting to rot. It may be that you didn’t grind your last batch long enough, or perhaps there is food stuck inside the unit or not flushed down the drain properly.

To eliminate these odors, you should run plenty of cold water into the unit and turn it on. Allow it to fully grind and flush all items inside the chamber. Next, you should thoroughly clean your disposal to eliminate all bacteria that may be lingering and contributing to the odor.

Back to all FAQs

What’s the difference between continuous & batch feed?

These are the two types of disposals you will choose from. Here is a general summary that highlights the differences between the two.

  • Continuous Feed:

    The most common type of disposer found in homes, these are considered to be effortless and simple to use. All you do is turn on the cold water, flip the power switch and add your food scraps. You can continue to let the unit run until all food waste has been grinded and disposed.

  • Batch Feed:

    Slightly more difficult to use, this type of disposer only allows you to grind food in smaller batches. In order for these to work, you must use a stopper to activate the power. Without the stopper, the device will not work. While they require a bit more work, they are considered to be the safer option.

Which one is better?

This is entirely dependent on your situation. Like most appliances, they each come with their own set of pros and cons.

Back to all FAQs

Do you need to run water when using a garbage disposal?

Yes. It is recommended that you run the water while you operate the disposal. This will not only help the device grind your food waste, but also guide the small particles down the drain and prevent potential problems, such as a clog in your pipes or within the disposal.

  • Cold Water:

    When you are grinding food waste, you should always use cold water. This will prevent the fats within your food from liquefying, which may create a clog when the temperature cools and these fats once again solidify. By running cold water, you keep these fats in a “solid” state, which makes it easier to grind and eliminate.

  • Hot Water:

    When you are cleaning your disposal, you can use hot water. However, this is dependent on how you are cleaning it. If you are using cleaners, such as vinegar, baking soda or citric acid, hot water will be fine, perhaps even helpful. However, if you are grinding food — such as citrus peels — to help clean the disposal, then you should stick with cold water.

Back to all FAQs

How do you install a garbage disposal?

While there are some general commonalities that are helpful to know, there are no specific set of installation instructions that work for every garbage disposal.

It is always recommended that you refer to and follow the owner’s manual that came with your disposal for precise installation instructions.

Garbage Disposal Installation

  • Replace:

    The installation process for replacing a garbage disposal is a somewhat complicated project for the average homeowner. If you’re relatively handy, you will likely have no trouble doing it on your own. However, if you are not confident in your plumbing skills, it would be best to hire somebody.

  • New Install:

    If you are adding a disposal as part of a kitchen remodel, the installation process is going to be significantly more difficult than a simple replacement. Still not impossible for your average DIY homeowner, but you’ll now have to consider the cost of wiring and other possible electrical needs. It may be wise to hire somebody.

Back to all FAQs

Can I call someone to help with installation?

Absolutely! There are plenty of handyman, plumbers and other general contractors out there that will do this job. Just make sure you do your research and hire only a qualified, certified and licensed contractor. If you decide to go this route, make sure you read these tips from the FTC first.

Depending on the retailer that you bought your garbage disposal from, they may offer installation services. Likely, this will include an extra charge, but it’s well-worth the security of knowing that your unit is installed correctly, by a professional.

Back to all FAQs

Are disposals loud?

Yes… and no. This is hard question to answer, really.

The overall decibel level will vary from model to model. Because it’s a motorized appliance, all garbage disposals will create some level of noise during operation. Much of the noise is due to the vibration created while the disposer is being used.

If noise is something you are concerned about, then you should look at buying a garbage disposal that has built-in insulation and anti-vibration features. Some manufacturers will also list the decibel level within the specs of each model.

Back to all FAQs

Why is my garbage disposal humming / buzzing?

A common problem that homeowners may experience, this humming sound occurs when the disposal is clogged or jammed by an object inside. The unit is still receiving power when you try to operate it, but unfortunately, it is unable to grind food because it is jammed.

You do NOT need to call a plumber for this. It is a relatively easy fix that should only take a few minutes.

How to Unclog:

Find the owner’s manual for your disposal. Look for instructions on how to troubleshoot this humming problem. If you can’t find the owner’s manual for specific instructions, then you should carefully try to unjam it.

You can try following these instructions:

  • Unplug disposal.
  • Get the allen wrench that came with the unit, or find one that will work.
  • Crawl under your sink and look for a small hole that fits your allen wrench. It will be hexagon-shaped.
  • Insert allen wrench and turn. This should unjam the unit.
  • Plug in and turn it on.

Note: These are general instructions to unclog your garbage disposal. It is strongly recommended that you follow the instructions that the manufacturer provides for that specific model.

Back to all FAQs

Where is the reset button on my disposal?

The reset button on your disposal is located at the bottom exterior of the unit. It is likely red, but this could vary. Please refer to the owner’s manual to understand how to properly use the reset button on your specific disposal.

Back to all FAQs

Can I use a disposal if I have a septic system?

You can, but it’s not recommended. When you have a septic system, disposing of food waste down the drain is a bad idea for the following reasons:

  • You may disturb the balance of bacteria within the tank.
  • You fill up the tank quicker, thus have to pump it more frequently.
  • You may inadvertently cause problems with the tank, which may lead to costly repairs.
Back to all FAQs

Who do I call to repair a disposal?

A plumber will be your best bet for repairing a garbage disposal.

However, depending on what the problem is, you may be able to repair it yourself. Before you call and hire someone, try to troubleshoot the problems and determine if you can fix it on your own.

For example, a clogged disposal is an easy fix for homeowners to do on their own. But, if the disposal is leaking, then you should turn off the water and call a a plumber.

Back to all FAQs

Where can I buy a garbage disposal?

You can buy a garbage disposal from a wide variety of retailers, including both online or inside a store.

Before buy the first disposal you find at Home Depot or Lowes, we would recommend browsing your options online and narrowing down which model would be best for your home. You don’t have to buy online, but you’ll at least have comfort in knowing that you made an educated buying decision.
