What to Do After Flooding or Hail Damages Your Air Conditioning System

Air conditioners are designed to withstand weather, including rain and snow. However, if your outdoor air conditioner is drenched in standing water from a large downpour, this can severely damage the electrical components within. Your cooling is most likely to get damaged if the floodwater reaches a foot deep. Still, if the unit has flooded at all, call Comfort Masters Service Experts at 847-250-6729 for an air conditioning inspection.

If extreme flooding has occurred or is likely to take place, follow these instructions to avoid damaging your AC unit or making dangerous operating conditions.

Before Flooding

Don’t cover your air conditioner with anything. A plastic sheet won’t keep out water. Instead, it will draw moisture inside, encourage rust, encourage mold growth and give pests a spot to hide.

If you reside in a flood-prone area, think about installing your air conditioner on a high platform. This elevates the equipment above any floodwaters and can save you hassle and expense when you have to deal with the next downpour.

Another way to protect your air conditioning system is to install a retaining wall around it. This structure can help you avoid air conditioner flooding, even as water flows around it. Similarly, you can place sandbags around the equipment when you know a storm is approaching.

If hail is predicted, you can lay sections of plywood across the top of the air conditioner to protect it from hail damage. Weigh the boards down firmly with stones or bricks in case the wind gets stronger.

During Flooding

Don’t use your air conditioner while it’s surrounded by water. Doing so could result in an electrical shock hazard or even ruin the internal system components.

To skip these issues, switch off the power to the air conditioner and thermostat. The easiest method for accomplishing this is to locate the HVAC and thermostat breakers in your junction box and turn them to the “off” position. If you need help, call an air conditioning service company like Comfort Masters Service Experts.

After Flooding

Once the rain subsides, you want your system to dry out as soon as possible. Remove standing water, if possible, and pick up any debris from the nearby area.

Don’t start the system until it has been checked by an HVAC technician. Even after it has dried out, running flood-damaged equipment could present the same hazards as using the air conditioning while it’s still submerged in water. Some issues need days or weeks to begin showing symptoms, so it’s smart to keep your unit turned off until you get the okay from an HVAC technician.

While you wait for your service visit, read through your homeowner’s insurance policy to see if flood damage covers your outdoor air conditioning system. If so, take pictures of the damage and present your claim quickly. If you don’t have flood insurance, you might still be covered if the unit has sustained wind or hail damage.
