The median home value is $381,900, and median household income is $77,041. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Maricopa County show 24 hail days and 79 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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.
