Steps to Take After Flooding or Hail Damages Your Air Conditioning System

Air conditioners are designed to withstand weather, such as rain and snow. However, if your outdoor air conditioner is immersed in standing water from a torrential downpour, this can seriously damage the electrical components in it. Your AC unit is most likely to be damaged if the floodwater reaches a foot deep. Still, if the system has flooded at all, contact Boehmers/Cronin Emery Service Experts at 519-804-1617 for an air conditioning inspection.

If bad flooding has occurred or is likely to take place, follow these instructions to avoid damaging your air conditioner or making dangerous operating conditions.

Before Flooding

Don’t cover your air conditioner with anything. A plastic sheet won’t protect it from water. Instead, it will trap moisture inside, lead to rust, cause mold growth and give animals a place to hide.

If you are in a flood-prone location, consider moving your air conditioner on an elevated platform. This elevates the system above any floodwaters and can save you hassle and expense when you have to deal with the next downpour.

Another approach to protect your air conditioning unit is to place a retaining wall around it. This option can help you avoid air conditioner flooding, even as water surges around it. Similarly, you can place sandbags around the equipment when you know a storm is approaching.

If hail is predicted, you can place sections of plywood across the top of the air conditioner to guard it from hail damage. Weigh the plywood down securely with stones or bricks in case the wind picks up.

During Flooding

Don’t turn on your AC while it’s submerged in water. Doing so can result in an electrical shock hazard or possibly destroy the internal system components.

To skip these problems, turn off the power to the air conditioner and thermostat. The easiest method for doing this is to locate the HVAC and thermostat breakers in your junction box and flip them to the “off” position. If you require a second opinion, call an air conditioning service company like Boehmers/Cronin Emery Service Experts.

After Flooding

Once the rain moves on, you want your air conditioner to dry out quickly. Draw away standing water, if possible, and clean any debris from the immediate area.

Don’t run the system until it has been checked by an HVAC expert. Even after it has dried out, utilizing flood-damaged equipment could cause the same hazards as turning on the air conditioning while it’s still under the water. Some issues take days or weeks to begin having symptoms, so it’s smart to keep your unit turned off until you have the go-ahead from an HVAC tech.

While you wait for your service visit, go over your homeowner’s insurance policy to see if flood damage covers your outdoor AC system. If so, take pictures of the damage and submit your claim right away. If you don’t have flood insurance, you might still be covered if the unit has sustained wind or hail damage.
