Jacksonville Weather and HVAC Load
NOAA's 1991-2020 climate normals put Jacksonville at 943 heating degree days and 3,302 cooling degree days per year. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. A normal year brings 4 nights at or below freezing and 96 days over 90°F.

Jacksonville Housing Stock
The median Jacksonville home dates to 1986, according to the Census ACS. That makes the typical house 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. Owners live in 57.4% of occupied homes, roughly 221,000 households. With a median household income of $66,981 and a median home value of $266,100, local labor rates come out near the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 16 hail days and 72 days with damaging thunderstorm winds in Duval County. 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. Duval County also had 7 tornado days in that period.

Florida Licensing and Efficiency Rules
Florida is in the DOE's Southeast 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). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Florida license or registration number before the visit.
Before You Hire
- Maintenance plans often put members first in line for emergency calls.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- Ask what the emergency fee is before the truck is sent.
