NOAA's 1991-2020 climate normals put Tucson at 1,332 heating degree days and 3,423 cooling degree days per year. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. Count on roughly 12 nights below 32°F and 158 afternoons past 90°F in a typical year.

NOAA storm reports for Pima County show 26 hail days and 100 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.75 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. Pima County also had 6 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
- Keep two feet clear around the outdoor unit, including snow.
- Book maintenance twice a year, once before summer and once before winter.
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.

Heat Pump Repair Questions from Tucson Homeowners
What does heat pump repair cost in Tucson?
Most bills land between $190 and $920, including the service call. A typical visit is about $590. Night and weekend calls cost more.
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.
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.
