Clermont Housing Stock
Half the homes in Clermont were built before 2005 (Census ACS median), so the typical house is about 21 years old. Newer homes are built tighter, so oversized equipment is a common problem. It short-cycles, wastes energy and leaves rooms clammy. About 12,000 households here own their home, 68.4% of the occupied total. Homes here have a median value of $368,600 and households a median income of $79,789. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 7 hail days and 12 days with damaging thunderstorm winds in Lake County. The largest hail reported was 2.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Lake County also had 3 tornado days in that period. In Clermont, 24.7% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

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 Clermont. 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.
Before You Hire
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
- Replacing both pieces at once usually costs less than two separate jobs a few years apart.
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.

HVAC System Replacement Questions from Clermont Homeowners
How much is full HVAC system replacement in Clermont?

When is the best time to schedule full HVAC system replacement in Clermont?
Between late fall and early spring. With 113 days over 90°F, Clermont contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
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.

Yes, as long as the indoor coil and blower work with the new AC. A mismatched system loses efficiency and can void the warranty.
