Best Small Window Air Conditioner: Questions and Answers

Small window air conditioner.

Can I use a small Window AC in a small bedroom, an apartment, or an RV?

This summer, you’ll surely need to find a solution to deal with the wet, hot, and sweltering summer. Over the years, manufacturers have really worked hard to find solutions for small rooms such as offices, apartments, and RVs. The result is a huge plethora of choices to suit virtually any kind of space.

These small units are especially useful when the size of your window won’t permit the installation of a bigger AC.

If your room space is below 400 square feet, these small window air conditioners will just be enough. This is because most of these are about 4000-6000BTUs which works well in such spaces.

For RVs and pop-up camper trailers, you’ll need to consider the fact that most of them are not sufficiently insulated. It would, therefore, be safer to buy a unit that is slightly higher BTUs than one recommended for your space area. Buying one recommended for your exact space could result in disappointments as it could turn out weaker due to insufficient insulation.

Also, the EER (Energy Efficiency Rating) of the window unit could have a significant impact on electricity bills. The higher the efficiency, the more the lower power bills you are likely to receive.

However, a lot can be done to ensure the window air conditioner in your RV works as expected without adding much to the bills. Placing your RV in a shade and insulating the inside of the RV can greatly reduce the amount of energy required to keep the RV in your preferred temperature. Regular maintenance can also help a lot because it will ensure the unit is always running at optimum conditions.

How to install and clean small window ACs.

First, you’ll need to arm yourself with the necessary tools for this job, namely a spirit level (or an equivalent), a tape measure, a drill, and a screwdriver.

Inspect and prepare the window by installing rails, flangers, and panels as stipulated by the manufacturer’s manual.

Secure the appliance by tightening the screws on drilled pilot holes and sealing it completely with foam strips and side panels. Make sure the unit is level by using the spirit or a torpedo level.

Test it by connecting it to a three-pronged outlet. If none is within easy reach, you will have to purchase an extension cord that is compatible with a window air conditioner.

How small can a window air conditioner be?

There are of course many good small quiet windows AC units available that are as small as 11 inches tall. These are very ideal for people with tight budgets or those looking to cover small spaces effectively.

You must, however, take caution as the smaller the AC the less space it will be able to cool.

Frigidaire’s 8000BTU FFRE0833Q1 model works very well for spaces of 350 square feet and below. An even smaller unit for ultra-small spaces such as those measuring about 150 square feet is available from homeLabs that produces 5000BTUs. Some of the best small window ACs are available in major retail and online stores such as Amazon, Target, Walmart, and Lowes.

What is the cost of small window ACs?

The price of small window air conditioners will vary depending on the features incorporated.

Some, like Frigidaire’s 5000BTU window-mounted mini AC, go for as low as $150 like while others will sell for over $900. Most of the time, the price is dependent on factors such as noise level, or how smart the AC is.
