A flood can cause devastating damage to heating and cooling systems and create an even more dangerous situation for homeowners (for example refrigerant lines could be breached, electrical can be compromised and internal components can get damaged by corrosion). Therefore, when it comes to flooding, better safe than sorry. Prevention is key and can save people not only money but the stress and heartache of a terrible experience.

Relocate equipment to a higher position

Many homes have heating and cooling systems installed in basements or lower levels. A change in location can make a huge difference. Homeowners should evaluate the cost of hiring a professional crew to invest in the relocation plan, it will save more money in the future. The equipment can be installed in the attic or and upper level. Also, this would be a great opportunity to compare with other technologies available in the market and maybe change into something smaller and more efficient. Split-ductless heat pumps are a great investment, they don’t require ductwork, take much less space and can be very easy to install. Outdoor units can sit on the side of your house, well above flood waters.

When relocating the equipment is not an option, users can consider hiring a contractor to build a flood wall around your furnace and air conditioner to protect them from water.

Verify appliances

After a flooding took place, only professionals can certify if appliances have been damaged by corrosion or not. Not matter if they run electricity or natural gas, both technologies have their weak spots when it comes to water damage. Radiant floors are not immune to floods, and also require a professional inspection. When dealing with propane equipment, professionals should replace all flood damaged controls, valves and gas pressure regulators as soon as possible.

Fungi & Bacteria

After a flood takes place, and even after the water is gone, moisture and humidity remain and damage whatever come in their way, even equipment that was not submerged during the flood. For systems that require ducts, they should be thoroughly dried, disinfected and cleaned by professionals. Also professionals should remove and replace all water-contaminated filters and insulation within and around cooling and heating components.

Floods & Split Air Conditioners and Heat Pumps

Due to its high usual position, split air conditioners and heat pumps are very unlikely to get affected and damaged by floods. In any case, a professional should always check the equipment.  

Damages equipment should be remove

The (AHRI) Air-Conditioning, Heating, and Refrigeration Institute, recommends replacing rather than repairing flood-damaged systems A new central air conditioner or heat pumps must achieve a minimum Seasonal Energy Efficiency Ratio (SEER) of 13. The Federal Government may have programs to help homeowners replace flood-damaged cooling and heating equipment. This would be a good time to upgrade to more energy efficient models, such as ductless systems, to save on electricity bills and enjoy maximum comfort.
