Orlando Weather and HVAC Load
NOAA's 1991-2020 climate normals put Orlando at 524 heating degree days and 3,451 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. Count on roughly 2 nights below 32°F and 110 afternoons past 90°F in a typical year.
| Heating degree days / year | 524 |
|---|---|
| Cooling degree days / year | 3,451 |
| Nights at or below 32°F | 2 |
| Days above 90°F | 110 |
| Average low / high | 62.7°F / 83.2°F |
Orlando Housing Stock
The median Orlando home dates to 1991, according to the Census ACS. That makes the typical house about 35 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Orlando has roughly 50,000 owner-occupied homes, or 39.7% of households. With a median household income of $69,268 and a median home value of $359,000, local labor rates come out near 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

- Both the heating and cooling equipment are 15 years old or more
- Both units keep needing repairs
What Moves the Price
- Efficiency ratings: SEER2, AFUE and HSPF2
- Equipment sized to the house and climate
- Duct repair or replacement
- Permits and electrical work
- Furnace plus AC, or heat pump plus air handler
- Thermostat and zoning upgrades
We raised the national figures about 21% for Orlando 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
- Duct connections and sealing
- New, matched heating and cooling equipment
- A load calculation and system design
- Removing the old equipment
- Startup, testing and 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). Expect the contractor to pull a mechanical permit for a replacement job in Orlando. 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
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Get one quote for a heat pump system and one for a furnace plus AC.

HVAC System Replacement Questions from Orlando Homeowners
How much is full HVAC system replacement in Orlando?
Plan on $10,300 to $22,300, with most jobs near $16,900. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule full HVAC system replacement in Orlando?
Between late fall and early spring. With 110 days over 90°F, Orlando contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
How often should an HVAC system be replaced?
Most systems get replaced every 15 to 20 years. AC units and heat pumps usually wear out before gas furnaces do.
Can I replace only the AC and keep my furnace?
Yes, as long as the indoor coil and blower work with the new AC. A mismatched system loses efficiency and can void the warranty.
