Cape Coral AC and Hurricane Season Checklist for Homeowners

A free seasonal checklist for homeowners in Cape Coral and the rest of Lee County, from Get HVAC Pros.

Air conditioning is a year-round job

Across the Caloosahatchee at Fort Myers, NOAA counts about 3,353 hours a year with the wet-bulb temperature above 73°F, and the 1% summer design temperature is 93°F with a mean coincident wet-bulb of 78°F. In Cape Coral the air conditioner is also the dehumidifier, and it rarely gets a season off. This checklist is organized around the hurricane calendar, because that is when an outage or a damaged unit costs the most.

January to March: the off-peak service window

  • Book the annual service now, when the system is under light load and technicians have time. Ask for coil cleaning, drain treatment, electrical checks and the temperature split, written on the ticket.
  • Replace the filter and keep spares. In this climate a dirty filter also means a wetter house.
  • Check the condensate drain and float switch. Attic and closet air handlers sweat constantly, and an overflowing pan is a common cause of ceiling damage.

April and May: before hurricane season

  • Photograph the outdoor unit, its data plate and the indoor equipment. If storm damage leads to a claim, clear before-pictures help.
  • Check the pad and tie-downs. Ask your contractor whether your outdoor unit is anchored to its pad and whether the anchors are in good shape.
  • Decide on backup power. If you plan a standby generator, the City of Cape Coral's 2026 miscellaneous fee schedule lists a generator permit at $387. Ask the HVAC contractor what starting current the outdoor unit draws so the generator can carry it.

June to November: hurricane season

Hurricane Ian made landfall at Cayo Costa on September 28, 2022 with estimated maximum winds of about 150 mph. The lesson for HVAC is to plan for what happens after a storm.

  • Before a storm, turn the system off at the thermostat and the outdoor disconnect if you evacuate or expect flooding.
  • After a storm, do not restart a unit that was underwater or has visible damage. Water in the electrical compartment can make a restart dangerous. Have it inspected first.
  • Once power returns, watch the humidity indoors. A house closed up and hot for days grows mold quickly; run the AC and a dehumidifier as soon as it is safe.

Every month

  • Keep the outdoor coil clear of grass, mulch and salty grime; rinse it gently with fresh water if you live near open water.
  • Keep a hygrometer in the main living area. High indoor humidity is the early warning for most comfort problems here.

Replacement and permits

Florida is in the Department of Energy's Southeast region, where new split-system central air conditioners must meet at least 14.3 SEER2. The City of Cape Coral's 2026 schedule lists an air conditioning change-out permit at $100. Ask each contractor to include the permit in the quote, list the matched model numbers and explain how the new system will control humidity.
