AC replacement in Cape Coral

Start with a load calculation

The size of the new system should come from a Manual J style load calculation, not from the size of the old one and not from square footage alone. The DOE says an oversized system removes less moisture. In Cape Coral that matters more than almost anywhere: Page Field now averages 49 days a year with a mean dew point of 75°F or more, up from 22 in 1976 to 1990. A system that is too big cools the house fast, shuts off, and leaves it clammy.

Ask the company whether they ran the calculation, and ask to see it. If the quote says "same size as existing" and nobody measured windows or looked in the attic, that is a guess. Our AC sizing guide covers the rules of thumb and why the calculation beats them.

What an itemized quote should list

Replacement quotes for the same house can differ by thousands. Most of that gap is in what each company included, so get every quote broken out the same way:

• Tonnage (a ton is 12,000 Btu per hour of cooling) and the efficiency rating in SEER2.
• Whether the indoor air handler or coil is replaced, or only the outdoor condenser. A new outdoor unit is matched to an indoor one, so ask how the quote handles that.
• The refrigerant the new system uses.
• The pad or stand, line set, drain line and float switch, and the thermostat.
• The city permit and inspections.
• Haul-away and disposal of the old equipment, including recovering its refrigerant.
• Who registers the equipment warranty, and what labor warranty the company itself gives, in writing.

If one quote is far cheaper, it usually left something off this list. If one is far higher, ask what it adds. Our page on checking whether an AC quote is fair has the red flags.

The Cape Coral A/C change out permit

The city requires an A/C Change Out permit when AC units are replaced or duct work is done. Under the city's guideline (revised January 2026), only a licensed HVAC contractor (CAC), a mechanical contractor (CMC) or an owner-builder can apply. An HVAC Data Sheet is always required. Depending on the job, the city may also ask for a Notice of Commencement, a FEMA packet or elevation certificate, and a duct layout, and the property may need floodplain review. Inspections are an HVAC rough (when applicable) and an HVAC final. A new mini split needs a separate electrical permit.

If the property is in a flood zone, ask the company whether the new condenser has to sit on a raised stand and whether that is in the price. A company that offers to skip the permit is offering you a problem when you sell or file an insurance claim. You can check the contractor's license before they apply.

SEER2 minimums and the refrigerant change

In the Southeast, a split central AC installed on or after January 1, 2023 must meet 14.3 SEER2 if it is under 45,000 Btu per hour, or 13.8 SEER2 at 45,000 and up. The DOE says it is illegal for a contractor to install a split AC below the regional standard here. Heat pumps have a national minimum of 14.3 SEER2 and 7.5 HSPF2. A higher rating than the minimum costs more up front; whether it pays back depends on how many hours the system runs, and in a 227 day hot season it runs a lot.

Refrigerant changed too. Under EPA rules, new residential AC and heat pump systems are limited to refrigerants with a global warming potential of 700 or less, with a manufacture and installation compliance date of January 1, 2025. Systems whose components were all made before 2025 have no installation deadline. Your existing R-410A system can still be serviced and repaired, so a refrigerant leak alone does not force a replacement. Ask which refrigerant the new system uses and whether the line set is being reused.

Cost and the FPL credit

System	Published range, installed	Average
Central air	$5,800 to $14,400	$8,750
Heat pump	$5,000 to $15,000	$8,350
Ductless mini split	$4,577 to $8,328	$6,357

Most of Cape Coral buys power from LCEC, not FPL. LCEC serves more than 240,000 customers including Cape Coral, North Fort Myers and Pine Island. I found no LCEC AC rebate; LCEC offers a free usage analysis on its website. If you are an FPL residential customer (much of the city of Fort Myers is), FPL offers a $200 instant credit on a new indoor and outdoor system rated 15.2 SEER2 or higher, installed by an FPL Participating Independent Contractor. There is no credit for the same system within two years. Ask the company whether it is a participating contractor before you count on the credit.
