Tempe Weather and HVAC Load
In a normal year, Tempe racks up 1,183 heating and 3,680 cooling degree days (NOAA 1991-2020 normals). 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 10 nights at or below freezing and 179 days over 90°F.
| Heating degree days / year | 1,183 |
|---|---|
| Cooling degree days / year | 3,680 |
| Nights at or below 32°F | 10 |
| Days above 90°F | 179 |
| Average low / high | 55.1°F / 88.4°F |
Tempe Housing Stock
Census figures put the median build year in Tempe at 1983, so a typical house here has about 43 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 41.6% of occupied homes, roughly 32,000 households. Homes here have a median value of $421,900 and households a median income of $77,643. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 24 hail days and 79 days with damaging thunderstorm winds in Maricopa County. 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.

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. Equipment replacements in Tempe generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Arizona license or registration number and a certificate of insurance with the quote. 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
- Ask your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- A combi boiler frees up space and replaces your water heater.
