About HVAC in Tucson
Tucson averages daytime highs near 100°F in June and July, so air conditioning runs for much of the year, while January nights average around 39°F and still call for heat. Arizona HVAC contractors are licensed by the Registrar of Contractors (ROC) in the air conditioning and refrigeration classes R-39, C-39 or dual CR-39. Tucson Electric Power’s Efficient Home Program gives rebates on high-efficiency heat pumps, duct sealing and tune-ups done by participating contractors.
