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, which is why compressors and condenser fan motors wear out faster here than in northern cities. A normal year brings 10 nights at or below freezing and 179 days over 90°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 Licensing and Efficiency Rules
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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Arizona the company should carry a state license or registration. Ask for both.
Before You Hire
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.
- Keep two feet clear around the outdoor unit, including snow.

Heat Pump Repair Questions from Tempe Homeowners
What does heat pump repair cost in Tempe?
Most bills land between $230 and $1,110, including the service call. A typical visit is about $710. Night and weekend calls cost more.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
