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, which is why compressors and condenser fan motors wear out faster here than in northern cities. Freezing nights are rare here, but a normal year brings 74 days over 90°F. On the cooling side, a 2,000 sq ft house here usually needs around 4 tons. A tight, well-insulated house may get by with half a ton less.
| 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 It Makes Sense
- The house can't reach the thermostat setting on hot afternoons
- It still runs on R-22 refrigerant
- It has had more than one refrigerant leak
- Summer electric bills keep going up
What Moves the Price
- The pad, permit and refrigerant (R-410A or the newer R-454B)
- SEER2 rating and whether the compressor is single-stage or variable-speed
- Tonnage, based on house size and local climate
- Electrical work such as a new disconnect, breaker or wiring
- Whether the coil and line set also need replacing

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 a Manual J calculation. "Same size as the old one" isn't sizing.
- Ask what federal, state or utility incentives apply to the model you're quoted.
- Fall and early spring installs often come with better pricing and shorter waits.
