West Palm Beach Weather and HVAC Load
NOAA's 1991-2020 climate normals put West Palm Beach at 201 heating degree days and 4,165 cooling degree days per year. Cooling carries most of the load. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. Freezing nights are rare here, but a normal year brings 74 days over 90°F.
| Heating degree days / year | 201 |
|---|---|
| Cooling degree days / year | 4,165 |
| Nights at or below 32°F | 0 |
| Days above 90°F | 74 |
| Average low / high | 68.6°F / 83°F |
West Palm Beach Housing Stock
Half the homes in West Palm Beach were built before 1987 (Census ACS median), so the typical house is about 39 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. West Palm Beach has roughly 25,000 owner-occupied homes, or 50.2% of households. With a median household income of $69,261 and a median home value of $369,800, local labor rates come out near the national middle in our model.
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 West Palm Beach, 20.3% 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
- A tech found a cracked heat exchanger, or the CO detector has gone off
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
- BTU size, which should come from a Manual J load calculation
- New PVC venting if you move to a condensing model
For West Palm Beach we lowered the national figures about 11%, 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
- The new furnace, filter rack and thermostat wiring
- Combustion and safety tests
- Gas line and vent connections
- The permit and the manufacturer warranty registration
- Removing and hauling away the old furnace
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). Expect the contractor to pull a mechanical permit for a replacement job in West Palm Beach. If a bidder suggests skipping it, move on. Also ask for a 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.
- 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.

Furnace Replacement Questions from West Palm Beach Homeowners
How much is furnace replacement in West Palm Beach?
Plan on $2,900 to $7,000, with most jobs near $5,200. 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 West Palm Beach?
Between late fall and early spring. With 74 days over 90°F, West Palm 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.
