The Hammocks Housing Stock
Census figures put the median build year in The Hammocks at 1991, so a typical house here has about 35 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 12,000 households here own their home, 61.2% of the occupied total. The median home value is $437,700, and median household income is $83,253. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 12 hail days and 29 days with damaging thunderstorm winds in Miami-Dade 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. Miami-Dade County also had 6 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 The Hammocks; 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
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
- Get one quote for a heat pump system and one for a furnace plus AC.

How often should an HVAC system be replaced?
