What to Look For in an Air Conditioner When shopping for a new air conditioner, you should first have a good idea of what type of AC unit you need. Are you looking to cool your entire house? Just a room? Knowing how large of a space you need to cool will help you narrow down your options and find an AC unit that delivers the right amount of cooling power for you. In general: Window Air Conditioners are best for cooling individual rooms and small spaces, like an apartment or dorm. Through-the-wall ACs are similar to window units, yet they do not rely on windows for installation. These are great if you want to cool a room that has no windows, or if you want to retain the ability to open your window as you please. PTAC units are ideal for hotels, nursing homes, dormitories, and other similar settings. They allow each room’s occupant to adjust their room’s temperature as needed without affecting other units in the building. They are also popular in apartments and condos. Ductless mini splits can cool as many rooms as you want without any sort of ductwork. Now that you know the basics of these types of AC units, here are some of our staff picks and customer favorites in each category. We hope this air conditioner buying guide will help you narrow down your search for the perfect system.
