How the rains affect your HVAC?

Showers can sometimes turn into a foot of floodwater that plays havoc on offices and homes. How do heavy rains affect your HVAC? While your unit is designed to withstand extreme weather conditions with the interior components secured by the best technology. The condenser and the compressor in the outdoor unit are made of copper, aluminum, and other such metals, and are crated in such a way that they can handle heavy rains while still dehumidifying and cooling the house effectively.

Here are a few problems that the HVAC may face:

Damage due to storms

Excessive rains with strong winds carrying debris can affect the condenser fan grille or may carry twigs, leaves, and dirt within your system. It is important to give the exterior of your unit a thorough check after every storm.

Flooding

Localized flooding can cause harm to the electronics within the air conditioning system if the waters cross fifteen inches. In case you experience such severe flooding after heavy rain, it is best to get your unit inspected professionally. Due to this reason, it is instructed to install the exterior HVAC unit in an area that is flood safe. Venting and ductwork under beam and pier houses should also be secured against flood water for making sure the operation runs safely and your family’s health remains intact.

Corrosion

Corrosion can happen inside a system that has been wrapped improperly when not in use. If you like to cover the HVAC with a cover that is commercially available, appropriate ventilation holes are necessary. Do not cover the HVAC with a garbage bag or plastic wrap. Condensation and moisture can build up and get trapped within the system, decaying rubber wire and rusting and corroding metal parts. Lack of any airing also promotes the breeding of mildew and mold, and creates an appealing nesting ground for vermin and insects.

How to protect your HVAC?

Humidity and water are a continuous force against HVAC systems, even while it does not rain. HVAC systems are well equipped to get rid of water and humidity levels in the air, but when the rains get heavy and push humidity to greater heights, the HVAC system has to work harder. A very common problem faced by homeowners is the water leakage coming from the components. One of the best ways to ensure that your HVAC works well throughout the year is to perform regular maintenance of the HVAC system. This ensures that there is enough volume within the drip pan for collection of water, and assure that the pumping system is suitable for emptying that collected water.



Flooding can be another issue. Is the exterior part of the HVAC sitting inside an area of the yard that offers no grading or drainage to get rid of the water? Is the HVAC unit installed on a roof surface which is a flat? When you look at the placement of your system with such a mindset, you can easily analyze the flood risks of the HVAC.
