Hey everyone, Tony Marino here. If you’re shopping for a new air conditioner, you’ve probably seen terms like 2-ton window air conditioner and 3-ton window AC unit thrown around. But what do these numbers really mean, and how do you choose the right size for your home?
In this guide, we’ll break down everything you need to know about these two types of window AC units—including their capacities, energy efficiency, installation, and maintenance. Plus, we’ll touch on the Goodman 3 Ton 14.5 SEER2 R-32 Bundle for homeowners looking for a whole-home cooling solution.
Understanding Air Conditioner Sizing
Before diving into the specifics, let’s clarify what “tonnage” actually means. In HVAC, a "ton" refers to the amount of heat an AC can remove in one hour. One ton equals 12,000 BTUs per hour. So:
-
A 2-ton window air conditioner removes about 24,000 BTUs per hour.
-
A 3-ton window AC unit removes about 36,000 BTUs per hour.
This measurement helps determine the appropriate size for your space. If your AC is too small, it will struggle to cool the room. If it’s too large, it will cycle on and off too frequently, wasting energy and wearing out components faster.
