NOAA's 1991-2020 climate normals put Scottsdale at 1,461 heating degree days and 3,151 cooling degree days per year. Cooling carries most of the load. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. A normal year brings 4 nights at or below freezing and 132 days over 90°F.

Scottsdale Housing Stock
Census figures put the median build year in Scottsdale at 1990, so a typical house here has about 36 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Scottsdale has roughly 80,000 owner-occupied homes, or 67.6% of households. Homes here have a median value of $709,900 and households a median income of $107,372. Those two numbers drive the labor adjustment in our estimate.
Maricopa County had 24 hail days and 79 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Maricopa County also had 4 tornado days in that period. In Scottsdale, 26.2% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

Arizona Permits, Efficiency Rules and Rebates
Arizona is in the DOE's Southwest region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). The Southwest also sets a minimum EER2, which measures efficiency at peak heat. Plan on a mechanical permit for most replacements in Scottsdale; the contractor normally pulls it. Before you sign, ask each bidder for their Arizona license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- For a steam system, hire a contractor who works on steam regularly.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- Ask your gas or oil company about rebates on condensing boilers.
