Why Costs Vary in Arizona
Arizona cooling loads can be high because sun exposure, attic heat, insulation, west-facing glass, and long cooling seasons affect BTU sizing.
Phoenix
Extreme summer heat can push BTU needs higher than square footage alone suggests.
Tucson
Sun exposure and older-home insulation are common sizing variables.
Flagstaff
Heating performance matters more than in lower desert markets.
