What a Full HVAC Replacement Costs
A complete system swap — outdoor condenser plus indoor air handler — typically runs $7,500-$14,500 in Fort Myers depending on tonnage, brand, and SEER2 rating. A condenser-only replacement (keeping an existing, compatible air handler) runs $5,200-$9,800.
Higher-efficiency systems (SEER2 16+) cost more upfront but cut summer electric bills meaningfully given how many hours these units run in Lee County; many homeowners recoup the premium within 4-6 years through lower utility bills.
Sizing for Fort Myers Homes
A properly licensed contractor runs a Manual J load calculation rather than just matching the old unit's tonnage, since older Fort Myers homes in areas like Dean Park or the McGregor corridor were often built with less insulation and different window ratios than newer construction in Gateway.
Typical residential systems here range from 2.5 tons for a small condo to 5 tons for larger homes near the river; oversizing wastes money and causes humidity problems, which matters more in a climate this humid.
Ductwork and Add-On Costs
Many homes built before the 2000s have ductwork that's undersized, leaky, or improperly sealed, adding $450-$2,200 in repair or resealing costs to a replacement project. Whole-home dehumidifiers ($1,800-$3,500) are a common add-on given Gulf Coast humidity levels.
Zoning systems for larger or multi-story homes typically add $1,500-$3,500 depending on the number of zones, and smart thermostats add $200-$500 including installation.
Permitting a Replacement in Fort Myers
Full system replacements require a mechanical permit from the City of Fort Myers Community Development Department's Building, Permitting & Inspections division at 1825 Hendry St, Suite 101 (permits@fortmyers.gov, (239) 321-7925), and the contractor's Florida DBPR license number must appear on the application.
Expect a rough-in and final inspection; most licensed local contractors build permit fees (typically a few hundred dollars, based on project valuation) into their quoted price, so ask whether the number you're given is permit-inclusive.
Typical cost ranges
| Condenser-only replacement (3-4 ton) | $5,200 - $9,800 |
