Pima County had 26 hail days and 100 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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. In Casas Adobes, 24.4% 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 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.
  • Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.

Heat Pump Repair Questions from Casas Adobes Homeowners

What does heat pump repair cost in Casas Adobes?

Most bills land between $210 and $1,020, including the service call. A typical visit is about $660. 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.
