NOAA storm reports for Palm Beach County show 21 hail days and 28 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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. Palm Beach County also had 13 tornado days in that period. In Boynton Beach, 22.7% 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
- Gas or electric bills keep climbing even though usage hasn't changed
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- A tech found a cracked heat exchanger, or the CO detector has gone off
- The furnace is 15 to 20 years old or more
What Moves the Price
- 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
- Single-stage, two-stage or modulating gas valve
- New PVC venting if you move to a condensing model
- BTU size, which should come from a Manual J load calculation

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 Boynton 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
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- 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.

Furnace Replacement Questions from Boynton Beach Homeowners
How much is furnace replacement in Boynton Beach?
Plan on $2,800 to $6,800, with most jobs near $5,000. 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 Boynton Beach?
Between late fall and early spring. With 66 days over 90°F, Boynton Beach 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.
