Top 10 Best Window-Mounted Air Conditioners in 2019 Reviews

When central air-conditioning becomes ineffective in cooling all the required areas, window-mounted air conditioners serve as energy efficient alternatives. They help bring some winter experiences in the middle of summer. These heat beaters are usually inexpensive, easy to install, and energy-savers. When hunting for an efficient window mounted AC, there are several things that you need to factor in.


Air conditioners are differentiated primarily by the amount of BTUs they offer. As a rule of thumb, each square feet of your room requires 20 BTUs of air conditioning. To identify which AC is perfect for you, you’ll need to multiply your room’s length by the width then by 20 BTUs. These measurements are meant for a room occupied by 2 persons only. 600 BTUs should be added for each additional person. Again, add 4,000 BTUs if the AC is intended for kitchen use.

Noise Decibels

You’ll need to consider the AC’s noise level depending on where you plan to install the AC. This matters most especially if the AC is to be mounted on the bedroom window.


This is one factor that most buyers overlook. It’s good to determine whether the air conditioner is designed for the double-hung or casement windows. Upon arrival and before installing, it’s important to ensure that the window is leveled for perfect draining. Additionally, check how easy it’ll be to install it. Does it come with a mounting kit?

Window-mounted air conditioners should be placed away from any heat generating units, for instance, TVs and lamps. It’s also important to ensure that the controls are easy to use. Ideally, the buttons should not be overcrowded and should be well labeled.

Filter location

Air conditioners use filters to trap dust particles, pet fur and other impurities from the air. It’s important to make sure that the filter can be easily accessed and removed for cleaning.

The list below has the best ACs you can order for on Amazon today.
