Gilbert Housing Stock
Census figures put the median build year in Gilbert at 2002, so a typical house here has about 24 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 73.9% of occupied homes, roughly 68,000 households. Homes here have a median value of $518,600 and households a median income of $121,351. Those two numbers drive the labor adjustment in our estimate.
Maricopa County had 24 hail days and 79 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. Maricopa County also had 4 tornado days in that period.

- Night, weekend or holiday rates

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. A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Arizona license or registration number before the visit.
Before You Hire
- Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
- Ask whether the diagnostic fee comes off the repair bill.
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
