How To Properly Handle A Home AC That's Been Exposed To Flooding

Posted on

Inch after inch of rain fell in your hometown, and your entire property took on a lot of water, including your home's central air conditioning unit. Even though these home implements are equipped to handle a fair amount of rain and moisture, flooding can be a completely different story; an air conditioner that has been exposed to floodwaters can require a bit of extra attention before it is put back in use. Take a look at the proper steps to take if your home's central air conditioning system has been exposed to a flood. 

1. Keep all power to the system off. 

One of the first things you should do if your home has been flooded (if it has not been done already) is to completely cut the power to the AC. Shut down the main breaker to the unit and make sure the thermostat is set to the off position. Keep in mind that the thermostat can send small energy signals to the indoor part of your AC if it is turned on, even if the breaker to the main unit is off. 

2. Remove any excess water from your system. 

You will need a good wet/dry vacuum cleaner and some heavy towels for this step. Take off the main housing of the outdoor unit and allow any excess water to drain out. You will need to use the wet vacuum to remove trash and debris from the coils on the exterior unit because it will probably be completely coated in junk. Remove as much water as possible from both the outdoor and indoor units. 

3. Check your ducts for water. 

If the AC was allowed to stay on after the flood, it could have pushed water into the duct system. Remove an access vent in the ducts closest to the indoor system and check for signs of moisture. If you see a lot of it, it is best to get a professional to your home to clean out your ducts. 

4. Expect to need to replace the condenser fan motor seal. 

The condenser fan outside is designed to withstand rain, but it is not capable of withstanding submersion in water. The motor has a seal that can become dislodged when it is submerged, and this seal will probably have to be replaced before your home's AC system will be safe to use again.
