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.
When Replacement Makes Sense
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- The furnace is 15 to 20 years old or more
- Gas or electric bills keep climbing even though usage hasn't changed
- A repair quote runs past a third of the cost of a new unit
What Moves the Price
- Single-stage, two-stage or modulating gas valve
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Permit and inspection fees, which the local building department sets
- Condition of the existing ductwork and any changes it needs
- New PVC venting if you move to a condensing model
- BTU size, which should come from a Manual J load calculation
We lowered the national figures about 4% for The Hammocks using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- Removing and hauling away the old furnace
- The permit and the manufacturer warranty registration
- Gas line and vent connections
- Combustion and safety tests
- The new furnace, filter rack and thermostat wiring
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
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
- Look up utility rebates on 95%+ AFUE units before you buy.
