Room Air Conditioner

Room Air Conditioners: How to Cool a Room Without Central AC

Many homeowners use a central air conditioner to control the temperature in their home, but this often comes with a hefty price tag and the requirement of cooling every room within your home. But, what if you can’t afford a central AC, or you just want to cool down one room? That’s where a room air conditioner can help.

Finding the best room ac unit for your home will depend on a variety of factors, including the size of the space, your budget, and your personal preferences.

Below, we will answer some of the most frequently asked questions people have about room air conditioners, as well as discuss the pros and cons of the different types available for you to choose from.

Let’s get started.

What Is A Room Air Conditioner?

A room air conditioner is any type of appliance that is designed to cool down an individual space, such as a room in a home or office.

Cost-effective and energy-efficient, this genre of air conditioners can be a suitable alternative for homeowners that don’t want to, or are unable to, invest in central air conditioning.




Are They Just For Small Rooms?

No. While they are commonly associated with smaller spaces, room air conditioners are available in a wide variety of sizes.

It’s important to know the size of the square footage of the room you’re looking to cool, and then calculate the amount of BTUs needed for that size space. You will also need to decide the type of AC unit that would work best for your room, which we detail down below.


Types of Room Air Conditioners

Now that we have a better idea of what a room air conditioner is, let’s take a closer look at the pros and cons of the different types you will choose from. Consider these pros and cons as you decide which air conditioner is best for your room.

Window Air Conditioners

Window AC Unit

Probably the most familiar type of room air conditioner, window cooling units are a great option for controlling the temperature within single rooms. There are many benefits to this type of AC unit. They are very affordable to purchase, with hundreds of models available from the most reputable brands in the space.

This low price point goes beyond the initial purchase, too. With a reputation of being extremely energy-efficient, you can count on saving even more money on your monthly energy bills. These costs can be further extended if you get an AC unit that has been rated by EnergyStar.

Window AC units come in just about every size, so no matter how large or small your room may be, it’s not hard to find one with the right amount of BTUs for your space.

The main downside of this type of room air conditioner is the installation requirements.

To work properly, window AC units do require permanent installation through a window that is partially open. This will allow the AC unit to vent hot air from the room. Without proper ventilation, the air conditioner would not be able to cool your room to your desired temperature.

While not an overly difficult task, installing a window air conditioner does present a challenge for many homeowners. If you don’t feel confident in your ability to install your AC unit, you will have to hire somebody to complete the task. This is an additional cost that many homeowners don’t consider at the time of purchase.

The Pros:

  • Affordable to buy and use.
  • Very energy-efficient.
  • Lots of options to choose from.

The Cons:

  • Installation may be difficult.
  • May need to hire someone to install AC unit.
  • Fixed location may require multiple units.

Portable Air Conditioners

Portable AC Units

In recent years, portable air conditioners have exploded in popularity. Likely because this type of AC unit is another great option for cooling individual rooms.

Portable AC units work just as their window counterparts, but offer the convenience of being light enough to move from room-to-room. Because they don’t require permanent installation, you have more flexibility in cooling strategic areas within your home.

Portable Air Conditioning

Portable Air Conditioner FAQs

Popular for cooling single rooms, here is a list of the most frequently asked questions about portable air conditioners.

Learn More

Installing a portable air conditioner is a very simple task that should pose minimal issues for homeowners. Simply click the window vent kit in place, and attach the hose(s) that come out of the back of the AC unit. This is how it vents hot air from the room.

Depending on the brand and model you buy, portable AC units are an affordable option with a large number of units to cool rooms of all sizes. However, the purchase price of a portable AC unit will be slightly higher than window units. But, because they are portable, you may only need to purchase one unit to cool various rooms.

The main downside of using a portable unit is that it will not be as energy-efficient as other types of room air conditioners on this list. At this time, you will not be able to find any portable air conditioners that have earned an EnergyStar rating.

The Pros

  • Affordable to buy.
  • Very simple installation.
  • Portable and easy to roll from room-to-room.

The Cons

  • Not as energy efficient as other room AC units.
  • Some units will be louder than others.

Ductless Air Conditioners (Mini-Split)

Ductless AC Unit

Ductless air conditioners, also known as a mini-split, are great at cooling large, open spaces. While they are not cheap to purchase, this type of room air conditioner is designed to work much like a central AC unit, qualifying it as one of the best alternatives for homeowners.

Consisting of a condenser outside that connects to the unit indoors, ductless AC units are mounted high up on your wall in an area that allows you to maximize the circulation of cool air across the entirety of your room. They take up zero floor space and are extremely quiet, allowing it to largely blend into the room.

Out of all the room air conditioners on this list, ductless AC units are going to be the most efficient. They use very little energy to operate, allowing you to cut your monthly energy costs by a significant amount. You can also find lots of ductless systems that are designed to cool multiple rooms, giving you maximum temperature control across your home.

Similar to buying a central AC unit for your home, the main downsides of ductless air conditioners are the overall cost of purchasing and installing it.

Unfortunately, the price tag for a ductless mini-split system is going to be much steeper than other room AC units. And once you get over the initial sticker shock, you also have to consider the cost of finding and hiring a qualified technician that can install it for you.

The Pros:

  • Surprisingly quiet.
  • Very efficient with minimal costs to use.
  • Doesn’t take up any floor space.
  • One unit can cool multiple rooms.

The Cons:

  • Expensive to purchase.
  • Need to hire a qualified technician to install.

Through-the-Wall Air Conditioners

Wall AC Unit

With a similar design as window units, this type of air conditioner is installed directly into your wall of the room you want to cool.

Wall air conditioners are the least popular type of unit on this list, and for good reasons. Most homeowners don’t want to spend the time and money to cut a hole into the side of their home, just to cool one room.

If you’re going to spend that amount of money, it would probably be wiser to invest into a ductless AC that doesn’t require a large hole in your home. It’s also going to be much easier to install and use a portable or window unit.

Despite these downsides, through-the-wall air conditioners are engineered to be slightly different than window units. This allows them to be slightly more efficient at cooling large, open rooms.

Wall AC units are also a great fit for cooling small sheds, workshops or other areas that don’t have a window and have little downside to cutting a hole in the wall.

It is important to remember that the difference between a window and through wall air conditioner does not lie in where they are positioned but in their structure. Through wall air conditioners vent warm air only through the back of the unit while window air conditioners work from both sides. These room air conditioners are not interchangeable.

The Pros:

  • Efficient and powerful.
  • Doesn’t take up any floor space.
  • Great at cooling large rooms and open spaces.

The Cons:

  • Potentially expensive to install.
  • Requires a hole in the wall.

Finding the Best AC For Your Room

Now that you have a better idea of what types of air conditioners can be used to cool a single room, let’s close this out with a few final considerations to help you find the best AC for your room.

No matter what you decide to buy, or how much it costs, this is a big decision that will affect your comfort level on a daily basis. It’s important to look at all the angles before you buy the first one you come across.




Ask yourself these questions:
  • What is the square footage of your room?
  • How much are you willing to spend?
  • Are you willing and able to do the installation?

Once you have the answer to these questions, you’ll be in a position to make an informed decision and find the best air conditioner for your room.

Window vs. Portable

Most homeowners will find that a window air conditioner is the most affordable and easiest to buy, but they may be hesitant when it comes to the installation process. If this is the scenario you find yourself in, then perhaps a portable air conditioner is the better option for you. Just know, that you’d be sacrificing energy efficiency for convenient installation.

Ductless = The Closest to Central AC

If you want to get closely replicate what you have with central air conditioning, then your best bet would be to buy a ductless air conditioner. But, they are more expensive to buy, and considerably more difficult to install. However, long-term, they are a great way to cool a room.

9 Tips to Using a Portable Air Conditioner

How to Get the Most Out of Your Portable AC

Like any new appliance you bring into your home, a portable air conditioner requires a little bit of getting used to, plus the typical cleaning and maintenance to ensure it is operating to its full potential. Regardless of where you install it or how often you use it, getting to know your indoor air conditioner and how it works within each room its placed, will go a long way in helping you get the most out of it.

To help you learn how to use your portable air conditioner, we’ve but together the following tips. These tips are designed to help you increase its efficiency, longevity and overall cooling ability. For more technical info, please refer to our list of FAQs here, or the user manual that came with your portable AC.

1. Strategic Installation

Be mindful of where your portable AC is installed. While not always avoidable, there are certainly some areas of your home that you should try to stay away from when you’re installing your unit.

Portable Air Conditioner

Sunny Spots

If possible, you will want to try to avoid placing the portable AC in an area that gets a lot of afternoon sun. If the heat of the sun is bearing down on your AC, it will likely need to work harder to keep the room at your desired temperature. This extra work may eventually lead to a shorter lifespan.

Humid Spots

It’s also wise to install and use your air conditioning unit in rooms that have low humidity levels. This is because the higher the relative humidity is inside the room, and directly surrounding the AC unit, the more condensation it will create.

Depending on the type of portable air conditioner you are using, this extra condensation may increase the frequency that it needs to be drained and cleaned. Failing to remove this will, ultimately, lead to the unit malfunctioning.

2. The Amount of Space Between Walls

One of the main benefits of this type of air conditioner is the fact that it’s portable. This gives you quite a bit of flexibility in the location of your home that it can be installed.




However, it’s still important to pay close attention to where you place it.

No matter where you decide to install the appliance, it is very important that you leave adequate space between the walls and the unit itself. Failing to leave enough space will limit the airflow. When your unit is unable to draw in enough air while it is in use, its output is reduced. As a result, this reduced output makes it harder for your portable air conditioner to cool the room to your desired temperature.

Refer to the user manual to know how much space the manufacturer recommends for your specific model.

3. Ventilation

No matter what type of room air conditioner you are using in your home, ventilation is always going to be one of the most important factors for ensuring optimal operation and a long life of the appliance.

Window Vent Kit for Portable AC

The importance of ventilation cannot be overstated, but it’s especially important when it comes to portable air conditioners.

Proper ventilation will direct the hot air from the compressor and out of the room. This will help prevent your AC unit from overheating, as well as keep the temperature inside your room from going up.

Use the Right Vent Kit For Your Window

Most portable AC units come with a window ventilation kit that’s designed to fit the majority of “standard-sized windows” in homes. However, depending on when your home was built, as well as the region you live or the style of your home, the definition of a “standard-size window” will vary.

It is unlikely that you should have any issues getting your ventilation kit to fit the windows in your home, but if you do, there are other ventilation options available, including kits for sliding doors and drop ceilings.

4. Keep the Exhaust Hose Straight

Now that we have ensured that the portable AC is properly ventilated, let’s now take a look at the exhaust hose. You will want to limit the amount of twists, kinks or coils in the hose leading from the unit to the window. The exhaust hose should remain straight with minimal contortions.

How to Save Money With Portable AC’s

If you’re clever in how you use your portable air conditioner, they can save you a lot of money. Here’s how you can use them to lower your energy bills.

Learn How

It is strongly recommended that you minimize any kinks in the exhaust hose that will limit the airflow or reduce ventilation. This may require a shorter exhaust hose, or just simply being mindful of where/how it is installed.

What Happens If the Exhaust Hose is Twisted?

When you have a long and twisted exhaust hose attached to your portable air conditioner, the unit has a harder time with ventilation.

As a result, the moisture in the air being expelled will start to accumulate inside the hose, and eventually start to trickle back down into the unit itself. If this happens, the cooling efficiency and the lifespan of the air conditioner may be reduced.

5. Clean & Replace Filter Regularly

This is probably pretty obvious to all homeowners, but the filter in your air conditioner should be changed regularly. This is not only important to ensure proper operation and cooling, but is essential for maintaining your indoor air quality.

How Often Should I Change It?

The frequency that you clean or change your filter all depends on how often you use the AC unit. It would be wise to inspect it every 6 to 8 weeks, just to make sure that it is in good condition. If your home is dusty, or if someone in your family is prone to allergies, then you may want to consider cleaning or replacing your filter more often.




What Happens If I Don’t Change the Filter?

If you’re using a clogged or dirty air filter, it may reduce the intake of the unit which may lead to a variety of problems.

These problems include:
  • Diminishes the efficiency, costs more to use.
  • Harder to reach and maintain desired temperature.
  • Forces the AC unit to work harder than it should.
  • May compromise indoor air quality.

Many of these issues will only occur when the filter is neglected for an extended period of time, but nonetheless, this shows why it’s important for all homeowners to regularly check and replace the filters in their air conditioners.

What If My Portable AC Has Multiple Filters?

Depending on the brand and model of the portable AC you’re using in your home, you may have multiple filters inside. All portable AC units come with a pre-filter, and don’t always require the use of other filters.

While these pre-filters are great at reducing large particulates that may be circulating in your air, they do very little for the common allergens that are known to lead to health complications, such as mold spores or pet dander. This is why it’s recommended that you use another type of air filter in your portable air conditioner.

6. Keep it Clean

Keeping your portable air conditioner clean is one of the easiest ways you can keep the device working properly, and it doesn’t take much work to complete.

AC Coil Cleaner

The Simple Clean:

Simply wipe down the outside of the unit down with a damp cloth. Avoid using excessively hot water or any sort of cleaning chemicals that may damage the exterior.

How Often? Do this every 4-6 weeks.

The Deep Clean:

Unplug your unit and clean the condenser coils to increase its efficiency. You can either purchase a coil cleaner to use or make your own cleaning solution with water and lemon juice. Spray the solution on the coils and remove after a few minutes.

How Often? Do this once a year.

The Professional Clean:

Sometimes, even when you clean the unit on a regular basis, you may require professional service to improve its functionality. If you experience issues with your unit that you are unable to resolve on your own, don’t hesitate to contact a professional air conditioning service to clean and inspect the appliance.

How Often? As needed.

7. Store it Properly When Not In Use

When you have no plans on using your portable air conditioner, it is recommended that you store it away to keep it safe for the next season. Try to avoid storing your AC unit in an area that has extreme temperatures, such as the garage or patio.

Checklist for Storing Portable Air Conditioners

Before you disassemble your AC unit and put it away into storage, it is strongly recommended that you do the following tasks.

  • All water has been drained from the unit.
  • Turn unit on fan setting to help the inside dry completely.
  • Deep clean all other parts and allow to dry, specifically exhaust hoses and drain pains.
  • Compress the exhaust hose to prevent damage while in storage.
  • Cover the unit with a sheet to prevent dust or other debris from accumulating.
  • Store your portable AC indoors in a climate-controlled area.

8. Electrical Requirements

When it comes to the power source for portable air conditioners, most homeowners shouldn’t have any issues. The vast majority of these AC units are designed to operate on the standard 120v electrical outlets commonly found in homes.




This is a pretty essential feature, as it would be difficult to move the AC unit from room to room if it required a different receptacle.

It may be a good idea to use a surge protector that can add a layer of protection against sudden power failures. It’s also recommended that you are mindful of how many appliances are plugged into the outlet, as to not overwhelm the circuit.

Note: This applies to the majority of portable air conditioners used to cool rooms in your home. If you’re using a commercial-size unit or a high-BTU air conditioner, you may need more electricity. All electrical requirements will be found in the user manual.

9. Pre-Cooling & Better Circulation

To help your portable AC unit cool your down in an efficient manner, it is recommended that you turn it on shortly before the room gets too hot or uncomfortable. If you wait until the sun is shining bright and the temperature is at its peak, the air conditioner will need to work harder, and take longer, to reach your desired temperature.

Another tip that every homeowner should know, is to use a small oscillating fan near the unit. This will help the cool air circulate throughout the room, and make you feel more comfortable.


Final Thoughts

There are many benefits that come from a portable air conditioner, but when you know how to strategically use it, you’ll find that you can improve its efficiency and extend its life.

By following the usage and maintenance tips listed above, you put yourself in the position to get the most from your AC unit, all while staying cool and saving money.

Beaucarnea recurvata

How to Grow a Ponytail Palm

As one of the most popular houseplants found in homes all around the world, the Ponytail Palm (Beaucarnea recurvata) is one of the easiest to grow and require very little maintenance by their owners. If you’re looking to add a splash of charm into your home, but don’t want to put much time or thought into it, then this tropical houseplant may just be the perfect choice for you.

Originating from the arid landscapes of Mexico, the name Ponytail “palm” is a bit of a misnomer. While the bulbous trunk indeed had some similarities to the trunks of other palm trees, the Beaucarnea recurvata is actually a drought-resistant succulent. And that bulbous trunk is where the plant stores its water.

Ponytail Palm

How to Care for Ponytail Palm

Ponytail palms are one of the easiest houseplants to care for.

They require little water, love lots of light, you don’t have to fertilize often, and they have the ability to adapt to the comfortable temperatures often found in homes. The downside of growing a ponytail palm inside your home is the incredible slow pace in which they grow.

As long as you don’t over-water it, you probably won’t kill it. It’s pretty much that simple.

However, if you want your plant to grow tall, thrive and be healthy, there are some easy guidelines you can follow to help you provide the best care for your ponytail palm.

7 Common Questions About Ponytail Palms

To help ensure that you’re providing to proper care for your ponytail palm, we have listed out the most frequently asked questions down below. If you have a question that you don’t see listed or would like to add additional feedback for others to learn from, please leave it down in the comment section below.

1. How often do you water a ponytail palm?

Not often, but the frequency depends largely on the environment you’re growing it in. Below, we have some general guidelines to watering a ponytail palm, but the best advice is to give it a drink of water when you see the soil start to dry.

  • During Hotter Months — You’ll want to water your ponytail palm plant once every 7-10 days.
  • During Cooler Months — You’ll want to slow down the watering schedule to once every 20-30 days.

If you don’t abide to that precise schedule, don’t fret. This plant is great at surviving long periods without water. But, if you want a healthy plant that grows to its fullest, you should try to follow the watering guidelines listed above.

Remember: The easiest way to kill a ponytail palm is by over-watering. Less is more.




2. How much light does it need?

Ponytail palms love lots of light. Remember, this plant is native to arid deserts, so full exposure to the sun will be appreciated by this plant. However, while full exposure is recommended, ponytail palms are adaptable to little or moderate amounts of light.

The downside of less light exposure is that you’ll see a noticeable slow down in its growth. And for an already slow-growing houseplant, this may just completely stunt it.

So, if you want your ponytail palm to grow tall, give it lots of light.

3. How often should I fertilize a ponytail palm?

Depends on the season and environment you’re growing your ponytail plant in. A general guideline is to fertilize your plant once every 3 or 4 weeks. If you see the tips of the leaves start to turn brown, then you’re using too much fertilizer.

  • Spring & Summer — Add fertilizer once every 2 or 3 weeks.
  • Fall & Winter — Add fertilizer once every 4 to 6 weeks.

Adding fertilizer is essential to the overall health of houseplants, and Beaucarnea recurvata is no different. Liquid fertilizers are recommended for ponytail palms, but granular fertilizers will also suffice. An all-purpose fertilizer will work fine here, but you can also consider using one formulated for cactus and other succulents.

4. What kind of soil should I use?

The best type of soil for this plant is one that drains quickly. Unlike many popular tropical houseplants, the last thing the ponytail palm wants is to sit around in moist soil for an extended period of time.

When you repot or transplant, it is recommended that you use a soil designed for cactus or succulents. If you want to make your own soil mixture, keep it light on the amount of peat you use within.

Remember: Keep the soil dry, and water sparingly.

5. Is repotting possible with a ponytail palm?

Yes, repotting a ponytail palm is possible and easy to do, but precautions should be made before you undertake this effort.

  • Size Matters — First, consider how large the tree is, and where you’re going to be moving it to. Larger plants will likely require more help from others, as well as a few other tools or equipment to assist in the transplant. On the flip side, if you’re repotting a small bonsai ponytail palm, then you likely won’t need any help or special tools.
  • Do In Spring — It is recommended that repot your ponytail palm early in the growing season, as this gives it plenty of time to adjust to the larger pot and form strong roots.
  • Examine the Roots — Once you have it out of the original container, take a close look at the roots of your plant. Look for any signs of bugs, rotted areas, or anything that looks injured or contaminated. Cut these off before you repot in new container.

Keep in mind: Transplanting it to a larger pot will encourage the plant to grow larger. This may be a deal-breaker for anyone growing a bonsai palm.

6. Is this plant safe for pets?

According to the ASPCA, the ponytail palm does not pose any toxicity threats to dogs or cats.

However, every homeowner with pets should know, and possibly take precautions if deemed necessary, that the leaves of the Beaucarnea recurvata contain saponin which may cause discomfort in some animals if ingested. So, while it’s unlikely that any harm will come to your dog or cat, it may be wise to keep an eye on them and ensure that they are not eating or chewing on the leaves.

It’s also worth noting that saponins are found in many popular houseplants, not just the ponytail palm. They also pose no danger to humans. In fact, saponin is found in many dietary supplements and are suggested to have some nutritional benefits.

7. Can you grow a ponytail palm outside?

Yes, but it’s recommended that you live in USDA Plant Hardiness Zone 10 or 11 if you want your plant to thrive. The sandy soil and hotter temperatures create an ideal environment for growing the ponytail palm outside.
