The Phoenix market
Phoenix's Planning and Development Department is unusually permissive about replacements. Its residential permit page lists water heater replacements done by a licensed contractor among projects that do not need a permit, while a DIY electric water heater replacement does. The page does not address DIY gas replacements. Air conditioner repairs or replacements that do not increase size and capacity or change location also need no permit. Furnaces and heat pumps are not addressed, and no fee was found for the DIY permit. The flip side: with no permit, no city inspector checks the work, so the contractor's license is your main protection. Cooling defines the market here, with EIA finding 94% of Arizona homes use air conditioning and a quarter heat with a heat pump. Mesa, Chandler, Scottsdale and other valley cities set their own rules.
Heat pumps handle Phoenix's mild winters easily, and the cooling side carries the house most of the year. Compare SEER2 ratings across bids before looking at the heating numbers. Ask how many heat pumps the contractor has installed in the valley. Arizona's state rebate status could not be confirmed from the official energy office site, so treat any quoted state rebate as unverified until you see the program and its terms.
