WebResidential air conditioners usually range from 1.5 to 5 tons (or, 18,000 – 60,000 BTUh). Anything with larger cooling capacity would be considered light commercial. Tonnage ratings are typically expressed in increments of .5 tons, so residential air conditioners are usually rated as 1.5, 2, 2.5, 3, 3.5, 4, 4.5 or 5 ton units.
