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

Air conditioners are constructed to resist elements, including rain and snow. However, if your outdoor air conditioner is submerged in standing water from a long downpour, this may severely damage the electrical components in it. Your AC unit is most likely to suffer damage if the floodwater reaches a foot deep. Still, if the unit has flooded at all, call Service Experts Commercial HVAC at 289-201-2346 for an air conditioning inspection.

If extreme flooding has occurred or is likely to take place, follow these steps to avoid harming your air conditioner or creating dangerous operating conditions.

Before Flooding

Don’t cover your air conditioner with a tarp. A plastic sheet won’t protect it from water. Instead, it will trap moisture inside, encourage rust, cause mold growth and give pests an area to hide.

If you live in a flood-prone spot, consider placing your air conditioner on an elevated base. This elevates the unit above potential floodwaters and can save you trouble and expense following the next downpour.

Another method to protect your air conditioning system is to place a retaining wall around it. This option can help you avoid air conditioner flooding, even as water rises around it. Similarly, you can stack sandbags around the system when you are alerted a storm is coming.

If hail is in the forecast, you can secure sections of plywood across the top of the air conditioner to guard it from hail damage. Weigh the plywood down safely with stones or bricks in case the wind gets stronger.

During Flooding

Don’t turn on your system while it’s surrounded by water. Doing so could create an electrical shock hazard or possibly destroy the internal system components.

To skip these problems, turn off the power to the air conditioning and thermostat. The fastest method for completing this is to locate the HVAC and thermostat breakers in your junction box and switch them to the “off” position. If you want assistance, call an air conditioning service company like Service Experts Commercial HVAC.

After Flooding

Once the rain subsides, you want your air conditioner to dry out quickly. Siphon off standing water, if possible, and clean any debris from the immediate area.

Don’t turn on the system until it has been checked by an HVAC technician. Even after it has dried out, using flood-damaged equipment can pose the same hazards as switching on the air conditioning while it’s still submerged in water. Some problems take days or weeks to begin revealing symptoms, so it’s wise to keep your air conditioning turned off until you get the go-ahead 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 submit your claim quickly. If you don’t have flood insurance, you could still be covered if the unit has experienced wind or hail damage.
