A flood is one of the scariest things any homeowner can face, and a flood is one of the hardest things on your HVAC system. When it comes to a central cooling system, there are multiple points that are especially vulnerable during a flood. Take a look at some of the most common air conditioner components that may sustain damage when floodwater rises and surrounds or enters your home. 

The AC's Duct System 

The duct system is commonly damaged during a flood because of its location. If you live in a home where the ducts are located in a crawlspace, your ducts are especially vulnerable to floodwater because they are outside and right next to the ground. Ducts in a basement can also be at risk if the water fills the basement and reaches the ceiling. Water can seep into the ducts, break down the insulation that surrounds them, and leave the ducts filled with debris. The ducts may be repairable, but it is most common for them to have to be replaced. 

The Electrical System 

Without a doubt, one of the most commonly damaged points of a central cooling system after a flood is its electrical system. The electrical system of a central air conditioning system holds a lot of delicate connectors and wiring. If the power to the unit is not shut off when the flooding happens, it can generate shortages and cause the circuitry to have issues within the electrical system. If you ever have to leave your home during a flood, it is best to shut off the main breaker to the house for this reason. However, if you didn't, you will likely be needing electrical repairs to the cooling system. 

The Exterior Condenser Unit 

The condenser unit is located outside, which means it is in a place where it is going to be most vulnerable during a flood. Unfortunately, a lot of the parts of the condenser unit can become damaged during a flood, especially if you try to turn the system on before cleaning out the unit. You may have debris stuck in the cooling fins and covering the condenser system itself, which can rapidly cause overheating of the system and lead to damages. It is always best to have an air conditioning repair technician come in and take a look at everything before you make the decision to start using your home's AC again after a flood.
