Storm Season and Your HVAC Equipment

Northeast Florida homeowners should include HVAC equipment in their storm preparations. Before hurricane season, know where the system disconnect and main electrical panel are, but only operate them if conditions are safe and you understand the equipment. Do not approach damaged wires, flooded equipment, or a wet electrical panel.

Secure loose outdoor items that could become projectiles. Do not wrap or cover an outdoor unit in a way that traps moisture or blocks ventilation during normal operation. Follow the equipment manufacturer's instructions for any storm protection.

If flooding, storm surge, or debris reaches the equipment, do not turn it on until it has been inspected by a qualified professional. Water can damage electrical components and contaminate equipment. Do not assume that an outdoor unit is safe simply because the water has receded.

After a storm, look from a safe distance for shifted equipment, damaged refrigerant lines, fallen branches, debris, exposed wiring, or water around the indoor air handler. Photograph visible damage for records if it is safe to do so. Contact your insurer and qualified contractors as appropriate.

If power is interrupted, follow utility and emergency-management instructions. Once power returns, avoid repeatedly cycling the system if it does not start normally. Some equipment has time delays or protective controls; consult the manual and call for help if operation is abnormal.
