Bonita Springs Housing Stock
Half the homes in Bonita Springs were built before 1997 (Census ACS median), so the typical house is about 29 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Bonita Springs has roughly 20,000 owner-occupied homes, or 80.6% of households. Homes here have a median value of $460,600 and households a median income of $90,486. Those two numbers drive the labor adjustment in our estimate.
Lee County had 7 hail days and 13 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Lee County also had 7 tornado days in that period. In Bonita Springs, 42.9% 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
- 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
- A repair quote runs past a third of the cost of a new unit
What Moves the Price
- Condition of the existing ductwork and any changes it needs
- New PVC venting if you move to a condensing model
- Permit and inspection fees, which the local building department sets
- Single-stage, two-stage or modulating gas valve
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- BTU size, which should come from a Manual J load calculation

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 Bonita Springs 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.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
- Look up utility rebates on 95%+ AFUE units before you buy.

Is a high-efficiency furnace worth it?
