When buying a through-the-wall air conditioner, you’re not just buying a box that blows cold (or warm) air — you’re making a 5- to 15-year investment. The brand you choose can determine:
-
How long your unit lasts.
-
How much you’ll spend on electricity.
-
How easy it is to use, clean, and service.
-
Whether it runs quietly or sounds like a jet engine in your living room.
