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.

The ductwork is usually original, and leaky joints are common. Tucson has roughly 116,000 owner-occupied homes, or 51.7% of households.

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
- Ask what the emergency fee is before the truck is sent.
- Maintenance plans often put members first in line for emergency calls.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
