What if your HVAC was Stuck in a Flood?

If you’re staring at a potential flood issue, the last thing on your mind will be your HVAC. But, once the waters have receded, it is something to consider. Do you repair? Do you replace? What should you do? Here are some things to consider as you take in the damage.

Storm Damage

While rain probably won’t damage your air conditioning unit, high winds that accompany it may cause falling objects like tree branches that damage the condenser fan grille or deposit leaves and other debris inside. It’s a good idea to inspect the exterior and interior of the unit after any severe storm.


Even though several inches of rainfall shouldn’t threaten your A/C, deep standing water from localized flooding could affect it. As long as flood waters don’t exceed around 15 inches in depth, the moving parts and electrical components of the outdoor unit should weather the storm.

Play It Safe

What you need to be careful of is using your HVAC after a flood. If damaged, the controls of your unit can be extremely dangerous. Any attempts to use air conditioning and heating equipment with defective gas control devices can potentially result in fires or even explosions. And, in the case of electric equipment, the risk of a life-threatening shock is just too risky to take the chance.

You may think your unit seems operational. And in some cases, it may be. But over time, the damage can still present itself. It might take weeks, or even a year, but once any control has been under water, it presents a serious hazard. Don’t risk it. It’s best to be safe and have a professional come out to inspect your unit.
Because so many things can go wrong as a result of floodwater, it’s usually cheaper, and always safer to replace, rather than repair.
