Pinal County had 13 hail days and 45 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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. Pinal County also had 3 tornado days in that period. In Casa Grande, 20.3% 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 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. Plan on a mechanical permit for most replacements in Casa Grande; the contractor normally pulls it. Before you sign, ask each bidder for their Arizona license or registration number and proof of insurance. 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.
- A combi boiler frees up space and replaces your water heater.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
