While central air systems are built to resist water and humidity damage, they are not yet designed to be submerged in water for long period of time. (We’ll let you know when that technology surfaces!)
Severe flooding, like what many residents and businesses in Texas experienced this summer, can be very damaging to your system. Thus, many residential and commercial HVAC experts advise that your take a few minutes to evaluate your indoor and outdoor units after severe rain or flooding.
First and foremost, turn off the electricity to your unit by switching the breaker via the fuse box. For outdoor units, the main flood damage problems are broken fan motor seals, corrosion in the electrical components and dirty heating coils.
Indoor units are typically easier to get damaged, so it is especially important to check the duct work after a flood.
Sometimes flood damage doesn’t really show until months afterwards, so have an HVAC technician take a look at your system just in case.
