When you don’t have central air, an in-wall air conditioner is a great option for effectively cooling down a room or area of your home.

To find the best wall air conditioner for you, you can narrow your choices down by square footage. For instance, you can shop for an in-wall AC unit for 400+ square feet. Keep in mind, however, that other factors also affect how much power (how many BTUs) you need. For example, rooms with high ceilings or drafty windows or doors require more cooling power. Small, easily sealed rooms might only need an in-wall AC with up to 7000 BTUs, but large spaces will require an in-wall AC with 13000+ BTUs.

In-wall AC units require an AC sleeve that holds them in place, making it an essential air conditioner accessory. If you want to understand more about the advantages of each design and the BTUs you might want for your space, look over this informative air conditioner buying guide.

There are a number of reasons why in-wall air conditioners might be the best option for your living space. First and foremost, it is significantly cheaper to get an in-wall AC unit than it is to install central air. Additionally, they are typically available in higher cooling capacities than window AC units, and they make it possible to keep using the windows in your room as you normally would.

Portable air conditioners can be also handy in a pinch, but they are usually less effective than window or wall AC units. When choosing the best portable air conditioner for your home, remember that portable units typically aren’t as powerful, but you can conveniently move them from room to room.

In-wall air conditioner units can help with allergy and mold issues because air conditioners help remove moisture, which decreases humidity. Plus, the filters are able to prevent many allergens from freely flying around in the air. Still, if you have serious allergies, you may also want to invest in an air purifier.
