Weston Weather and HVAC Load
Weston logs 121 heating degree days and 4,639 cooling degree days in a normal year, based on the closest NOAA weather station. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. Freezing nights are rare here, but a normal year brings 105 days over 90°F.

Weston Housing Stock
Census figures put the median build year in Weston at 1995, so a typical house here has about 31 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 16,000 households here own their home, 72.7% of the occupied total. With a median household income of $140,501 and a median home value of $644,100, local labor rates come out above the national middle in our model.
NOAA storm reports for Broward County show 15 hail days and 39 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.5 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. Broward County also had 7 tornado days in that period.

- Efficiency ratings: SEER2, AFUE and HSPF2

- Equipment sized to the house and climate

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). Equipment replacements in Weston generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Florida license or registration number and a certificate of insurance with the quote. 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
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Replacing both pieces at once usually costs less than two separate jobs a few years apart.
- Get one quote for a heat pump system and one for a furnace plus AC.

HVAC System Replacement Questions from Weston Homeowners
How much is full HVAC system replacement in Weston?
Plan on $14,300 to $31,100, with most jobs near $23,500. 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 Weston?
Between late fall and early spring. With 105 days over 90°F, Weston 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.
