NOAA's 1991-2020 climate normals put Alafaya at 468 heating degree days and 3,693 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 111 days over 90°F.

Alafaya Housing Stock
Half the homes in Alafaya were built before 2002 (Census ACS median), so the typical house is about 24 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 21,000 households here own their home, 65.1% of the occupied total. With a median household income of $98,289 and a median home value of $391,900, local labor rates come out above the national middle in our model.
NOAA storm reports for Orange County show 14 hail days and 21 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. Orange County also had 3 tornado days in that period.
When Replacement Makes Sense
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- The furnace is 15 to 20 years old or more
- Gas or electric bills keep climbing even though usage hasn't changed
- A repair quote runs past a third of the cost of a new unit
What Moves the Price
- Single-stage, two-stage or modulating gas valve
- BTU size, which should come from a Manual J load calculation
- Condition of the existing ductwork and any changes it needs
- Permit and inspection fees, which the local building department sets
- New PVC venting if you move to a condensing model
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
For Alafaya we kept the national figures close to unchanged, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.

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 Alafaya. 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
- Look up utility rebates on 95%+ AFUE units before you buy.
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- 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 Alafaya Homeowners

When is the best time to schedule furnace replacement in Alafaya?
Between late fall and early spring. With 111 days over 90°F, Alafaya contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
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.

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.
