Horizon West Housing Stock
The median Horizon West home dates to 2013, according to the Census ACS. That makes the typical house about 13 years old. Newer homes are built tighter, so oversized equipment is a common problem. It short-cycles, wastes energy and leaves rooms clammy. Owners live in 69% of occupied homes, roughly 14,000 households. Homes here have a median value of $498,700 and households a median income of $123,586. Those two numbers drive the labor adjustment in our estimate.
Orange County had 14 hail days and 21 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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.

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). Plan on a mechanical permit for most replacements in Horizon West; the contractor normally pulls it. Before you sign, ask each bidder for their 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
- Get one quote for a heat pump system and one for a furnace plus AC.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.

Between late fall and early spring. With 129 days over 90°F, Horizon West contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
How often should an HVAC system be replaced?
