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. In Deerfield Beach, 23.3% 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.
When Replacement Makes Sense
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- A repair quote runs past a third of the cost of a new unit
- Gas or electric bills keep climbing even though usage hasn't changed
- The furnace is 15 to 20 years old or more
What Moves the Price
- Condition of the existing ductwork and any changes it needs
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- BTU size, which should come from a Manual J load calculation
- Permit and inspection fees, which the local building department sets
- Single-stage, two-stage or modulating gas valve
- New PVC venting if you move to a condensing model
For Deerfield Beach we lowered the national figures about 18%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.

- Removing and hauling away the old furnace
- Combustion and safety tests
- Gas line and vent connections
- The new furnace, filter rack and thermostat wiring
- The permit and the manufacturer warranty registration
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 Deerfield Beach; 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.
- Look up utility rebates on 95%+ AFUE units before you buy.
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.

Is a high-efficiency furnace worth it?
