Apopka Weather and HVAC Load
NOAA's 1991-2020 climate normals put Apopka at 828 heating degree days and 3,134 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. Count on roughly 13 nights below 32°F and 120 afternoons past 90°F in a typical year.

Apopka Housing Stock
The median Apopka home dates to 2001, according to the Census ACS. That makes the typical house about 25 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Apopka has roughly 15,000 owner-occupied homes, or 80.4% of households. With a median household income of $95,703 and a median home value of $364,300, local labor rates come out above the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 14 hail days and 21 days with damaging thunderstorm winds in Orange County. The largest hail reported was 1.75 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. Orange County also had 3 tornado days in that period.

- Both units keep needing repairs
What Moves the Price
- Thermostat and zoning upgrades

Florida Permits, Efficiency Rules and Rebates
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). Expect the contractor to pull a mechanical permit for a replacement job in Apopka. If a bidder suggests skipping it, move on. Also ask for a Florida 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.

HVAC System Replacement Questions from Apopka Homeowners
How much is full HVAC system replacement in Apopka?
Plan on $10,900 to $23,700, with most jobs near $17,900. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule full HVAC system replacement in Apopka?
Between late fall and early spring. With 120 days over 90°F, Apopka contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
Can I replace only the AC and keep my furnace?
Yes, as long as the indoor coil and blower work with the new AC. A mismatched system loses efficiency and can void the warranty.
How often should an HVAC system be replaced?
Most systems get replaced every 15 to 20 years. AC units and heat pumps usually wear out before gas furnaces do.
