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

Air conditioners are built to endure precipitation, like rain and snow. However, if your outdoor air conditioner is immersed in standing water from a long downpour, this might severely damage the electrical components in it. Your cooling is most likely to be damaged if the floodwater reaches a foot deep. Still, if the system has flooded at all, contact Service Experts Heating & Air Conditioning at 239-908-6991 for an air conditioning inspection.

If extreme flooding has occurred or is likely to take place, follow these directions to avoid harming your HVAC system or creating dangerous operating conditions.

Before Flooding

Don’t cover your air conditioner with a tarp. A plastic sheet won’t repel water. Instead, it will draw moisture inside, encourage rust, cause mold growth and give critters a place to hide.

If you live in a flood-prone area, research installing your air conditioner on an elevated floor. This elevates the machinery above any floodwaters and can save you stress and expense after the next downpour.

Another approach to safeguard your air conditioning unit is to install a retaining wall around it. This structure can stop air conditioner flooding, even as water surges around it. Similarly, you can place sandbags around the equipment when you realize a storm is coming.

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

During Flooding

Don’t use your system while it’s surrounded by water. Doing so may create an electrical shock hazard or possibly ruin the internal system components.

To prevent this damage, disconnect the power to the air conditioning and thermostat. The quickest method for completing this is to locate the HVAC and thermostat breakers in your junction box and turn them to the “off” position. If you require help, call an air conditioning service company like Service Experts Heating & Air Conditioning.

After Flooding

Once the rain eases off, you want your air conditioner to dry out quickly. Draw away standing water, if possible, and pick up any debris from the immediate area.

Don’t start the air conditioner until it has been inspected by an HVAC technician. Even after it has dried out, utilizing flood-damaged equipment can pose the same hazards as turning on the air conditioning while it’s still under the water. Some issues need days or weeks to begin having symptoms, so it’s wise to keep your air conditioner turned off until you receive the go-ahead from an HVAC professional.

While you wait for your appointment, read through your homeowner’s insurance policy to see if flood damage secures your outdoor AC system. If so, take pictures of the damage and process your claim as soon as possible. If you don’t have flood insurance, you could still be covered if the unit has suffered wind or hail damage.
