NOAA storm reports for St. Lucie County show 8 hail days and 7 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2 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. St. Lucie County also had 4 tornado days in that period. In Fort Pierce, 21.4% 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
- The furnace is 15 to 20 years old or more
- A tech found a cracked heat exchanger, or the CO detector has gone off
- 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
What Moves the Price
- Condition of the existing ductwork and any changes it needs
- New PVC venting if you move to a condensing model
- Permit and inspection fees, which the local building department sets
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Single-stage, two-stage or modulating gas valve
- BTU size, which should come from a Manual J load calculation
For Fort Pierce we lowered the national figures about 24%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.
What the Quote Should Cover
- Gas line and vent connections
- Removing and hauling away the old furnace
- Combustion and safety tests
- The permit and the manufacturer warranty registration
- 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 Fort Pierce; 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
- Look up utility rebates on 95%+ AFUE units before you buy.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.

Furnace Replacement Questions from Fort Pierce Homeowners
How much is furnace replacement in Fort Pierce?
Plan on $2,400 to $5,900, with most jobs near $4,300. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule furnace replacement in Fort Pierce?
Between late fall and early spring. With 70 days over 90°F, Fort Pierce contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
Is a high-efficiency furnace worth it?
In cold climates, a 95%+ AFUE furnace usually earns back the price difference in lower gas bills. Where winters are mild, the payback can take a very long time.
How long does a furnace replacement take?
A straight swap is usually done in one day, somewhere between 4 and 10 hours. Moving to a condensing furnace with new PVC venting can add a few more.
