How various sq. ft. can a 13 seer, 2.5 ton a/c section cool stale?
Answers: 1 ton can cool roughly 400-500 sq/ft to 20 degrees below outdoor warmth, so a 2.5 ton unit will suffice for up to 1250 sq/ft. Live contained by the desert? Go with the lower number. Alot depends on your insulation, number of window, and ceiling height (8' is average). The SEER will not affect the operation of the part; only the amount of sparkle it uses.
I use 400sqf per ton with 8ft ceiling . 1000sqf to 1200 is perfect it will cycle 25 to 20 min on an 10 to 20 stale if you have clad insulation even during 105f days most A/C companys and builders under size unit that can run for hours at a time. Its an easy provide because they can charge a 1000$ or more less
