Boca Raton Weather and HVAC Load
In a normal year, Boca Raton racks up 133 heating and 4,607 cooling degree days (NOAA 1991-2020 normals). 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 59 days over 90°F.
| Heating degree days / year | 133 |
|---|---|

Boca Raton Housing Stock
The median Boca Raton home dates to 1983, according to the Census ACS. That makes the typical house about 43 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 65.8% of occupied homes, roughly 27,000 households. With a median household income of $102,722 and a median home value of $660,100, local labor rates come out above the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 21 hail days and 28 days with damaging thunderstorm winds in Palm Beach County. 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 Boca Raton, 24.7% 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
- A tech found a cracked heat exchanger, or the CO detector has gone off
- 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 repair quote runs past a third of the cost of a new unit
What Moves the Price
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- BTU size, which should come from a Manual J load calculation
- Single-stage, two-stage or modulating gas valve
- New PVC venting if you move to a condensing model
- Permit and inspection fees, which the local building department sets
- Condition of the existing ductwork and any changes it needs
We raised the national figures about 12% for Boca Raton using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- Removing and hauling away the old furnace
- The new furnace, filter rack and thermostat wiring
- Combustion and safety tests
- Gas line and vent connections
- 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). Equipment replacements in Boca Raton generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Florida license or registration number and a certificate of insurance with the quote. 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.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.

Furnace Replacement Questions from Boca Raton Homeowners
How much is furnace replacement in Boca Raton?
Plan on $3,600 to $8,700, with most jobs near $6,400. 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 Boca Raton?
Between late fall and early spring. With 59 days over 90°F, Boca Raton 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.
