Glendale Housing Stock
Half the homes in Glendale were built before 1986 (Census ACS median), so the typical house is about 40 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 50,000 households here own their home, 57.6% of the occupied total. Homes here have a median value of $347,000 and households a median income of $70,139. 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.
