In Holiday, AC mold usually starts with condensate that can't drain from the coil and pan, though coastal neighborhoods hit by Helene's surge also have to think about ducts and air handlers that took on water. EPA advises shutting off a system you suspect is contaminated. Call the number on this page to be connected with a local mold remediation company in Holiday.

Why does the AC in my Holiday home smell musty?
Holiday is a coastal Pasco County suburb between New Port Richey to the north and Tarpon Springs and the Pinellas line to the south, with neighborhoods such as Key Vista, Beacon Square, Holiday Lake Estates and Forest Hills. Gulf air keeps humidity high for much of the year, and the air conditioner removes that moisture over its coil. The water drips into a pan and leaves through a condensate line. When algae plugs the line or the pan rusts through, water sits inside the cabinet, growth starts on the coil, blower or insulation, and the odor arrives with the first air of every cycle. EPA's prevention advice is plain: keep drip pans clean, drain lines flowing and indoor humidity below 60 percent.
Helene's surge reached our neighborhood. What should we check?
After Helene in 2024, Pasco County delivered supplies to coastal neighborhoods directly affected by surge "from Holiday to Hudson." If water came into the house, check whether it reached floor returns, low ducts or an air handler in a garage or closet. EPA says a home that couldn't be dried within 24 to 48 hours should be treated as having mold and that wet duct insulation should be removed and replaced. Florida Department of Health in Pasco County guidance after the 2024 storms was similar: discard soaked items that can't be cleaned and dried within 24 to 48 hours, ventilate while removing wet or moldy material, and remove visible mold before painting or caulking. Pasco County's Find My Flood Zone tool shows a property's FEMA zone by address.
Do I need a permit for the repairs?
Mold removal itself isn't usually described as permitted work, but rebuilding walls, ceilings or structural parts afterward may be. Unincorporated Holiday is permitted by Pasco County Building Construction Services, whose central permitting office is at 8661 Citizens Drive in New Port Richey; the county posts post-storm permit information online. An HVAC contractor will know what its own equipment work requires.

Local note
Anclote River Park, Gulf Park and Key Vista Park give Holiday its beach access. Angi reports Tampa-area HVAC mold remediation typically runs $3,225 to $10,750, depending mostly on how much duct is replaced.
