Springtime is here, which also means that flood season is here as well. In the spring, floods are more common as rivers rise with melting snow and spring rain. If flood rains hit your hand, you need to know what to do to protect your air conditioning system.
A Little Rain is Okay
A little rain is okay. Your outside AC unit will be able to continue operating effectively in a couple of inches of flood water. When you need to get really concerned is when the water is a foot or more in depth around your air condition system. Things become dangerous when your air conditioning unit actually has to sit in standing water for an extended period of time.
Turn off All the Electricity
First, turn off all the electricity that is running to your AC unit when flood waters hit your home. Make sure that all the electrical controls that are connected to your AC unit are turned off. That includes the main circuit that both the inside and outside parts of your AC unit are connected to, including the fan.
Let Your Air Conditioning System Dry Out
Before you do anything with your air conditioning system, you need to allow your air conditioning system to dry out. For your air conditioning system to dry out, all the standing water from the area will have to dissipate. If the water is inside of your home, use a sump pump and wet-dry vacuum to get rid of the water. With outside water, you will just have to wait for nature to do its thing and the water to recede. If there is debris that has gathered around your air conditioning unit due to the flood waters, you will need to remove and clean up the debris.
Get Your Air Conditioning Unit Inspected
Do not try to repair your air conditioning unit on your own. Put in a call to your local repair service like NOW Heating & Air and get on the list to have your air conditioning system inspected. They will check all of the components to see if they are damaged. They will repair any electrical components that were damaged by the flood water, and make sure that all the water is clear from the internal components before turning on the unit again. An HVAC professional will be able to make sure your unit is safe to use again.
If flooding is expected around your home, don't put a tarp over the unit. This causes moisture to accumulate in the unit and damage it. Instead, put sandbags around the unit to keep water away. If water gets in the unit, turn off the electricity, allow the unit to dry out, and have your unit repaired and inspected by an HVAC technician before turning it on again after it has been impacted by a flood.
