Hurricane Impact on HVAC Systems
The Air-Conditioning, Heating and Refrigeration Institute (AHRI) instructs homeowner to take important safety precautions after a flood or hurricane with regard to their HVAC equipment and duct work.
The associations advises homeowners that standing water can severely damage a home’s heating and cooling equipment and recommends that flood damaged HVAC equipment be replaced rather than repaired.
Because manufacturers’ warranties do NOT cover failure or damage due to floods, winds, lightning and other conditions beyond the control of the company, we recommend that you contact FEMA (fema.gov) as government aid may be available to you.
If HVAC equipment has been submerged or damaged by flood water, it is recommended that all inspection and replacement work be done by a certified contractor and not the homeowner.
Please review the following information about home HVAC equipment and take necessary precautions to have that equipment inspected, as well as repaired or replaced, by a certified professional.
HVAC: Heat Pumps and Air Conditioners:
Split systems have power and control wiring between the indoor and outdoor units as well as piping through which refrigerant flow through the system. If flood water caused either the outdoor or indoor units of a split system to become repositioned, even by a small amount. There is a chance for potential refrigerant leak. The system will require major repair or full replacement if this occurs.
If refrigerant system remain intact after the flood, the entire system should be cleaned, dried and disinfected. Homeowners should have a contractor check the indoor and outdoor unit’s electrical and refrigeration connections, including all control circuits. The decision to repair or replace should be made after consultation with a qualified professional.
If a home that has incurred flood damage contains an HVAC system, it is important to closely inspect the air distribution system. Duct insulation that has been in contact with flood water should not be salvaged as it is impossible to decontaminate. A qualified contractor can clean, dry and disinfect the ductwork.
