The Florida Climate Trap

Florida’s sub-tropical heat isn't just uncomfortable—it is actively destructive to sitting RVs. When temperature and relative humidity spike:

  1. AC Compressors Overwork & Freeze: High humidity forces your rooftop A/C to process excessive condensation, often leading to frozen coils, blown capacitors, or complete compressor shutdown.

  2. Mold Spores Explode in Dark, Sealed Rigs: Stagnant air inside a closed RV acts like a greenhouse. Mold and mildew can spread across upholstery, cabinetry, and ceilings in as little as 48 to 72 hours.

  3. Seals Dry-Rot & Leak Moisture: The intense UV index breaks down rubber roof seals and slide seals, letting rain and humid ambient air seep directly into wall cavities.

Is Your RV At Risk?

If your camper is stored or parked in Florida and exhibits any of the following symptoms, moisture damage is already occurring:

  • [ ] The rooftop A/C runs continuously without lowering ambient temperature below 78°F.

  • [ ] Ice builds up on the A/C unit or water drips onto your interior floor.

  • [ ] A persistent musty or damp smell greets you upon entering the RV.

  • [ ] Cabinet surfaces, mattress bottoms, or wall panels feel clammy to the touch.

  • [ ] Roof sealant along seams or around vent caps is cracked, chalky, or peeling.

Florida RV Storage & AC Maintenance Best Practices

To keep your coach operational through peak summer and humidity seasons, follow these technician-tested protocols:

Maintain Proper Air Conditioner Airflow

  • Clean Filters Monthly: Dust mixed with Florida moisture creates a plaster-like coating on washable intake filters, restricting airflow and freezing coils.

  • Inspect Condenser Coils: Clear away dirt, bugs, and salt-air residue from top-deck coils to ensure efficient heat exchange.

Manage Humidity During Storage

  • Set Thermostats to 78°F–80°F: Never turn the A/C completely off in storage unless you run a dedicated continuous-drain dehumidifier.

  • Use Continuous Dehumidification: Pair a heavy-duty dehumidifier routed directly down a shower drain or gray tank to pull up to 30–50 pints of water per day from the cabin.

Inspect Roof and Slide Seals Bi-Annually

  • Small micro-fissures in Lap Sealant allow high-humidity vapor to enter structural framing before visible rain leaks ever appear.
