Air conditioners are built to endure precipitation, such as rain and snow. However, if your outdoor air conditioner is flooded with standing water from a large downpour, this might critically damage the electrical components within. Your AC unit is most likely to suffer damage if the floodwater rises above a foot deep. Still, if the unit has flooded at all, contact Service Experts Heating & Air Conditioning at (713) 352-7887 for an air conditioning inspection.
If extreme flooding has occurred or is likely to happen, follow these directions to avoid harming your air conditioning or generating dangerous operating conditions.
Don’t cover your air conditioner with anything. A plastic sheet won’t keep out water. Instead, it will draw moisture inside, encourage rust, hasten mold growth and give pests a place to hide.
If you are in a flood-prone spot, research placing your air conditioner on a high stand. This elevates the system above possible floodwaters and can save you trouble and expense following the next downpour.
Another approach to protect your air conditioning equipment is to create a retaining wall around it. This option can help you avoid air conditioner flooding, even as water surges around it. Similarly, you can stack sandbags around the system when you know a storm is coming.
If hail is expected, you can place pieces of plywood across the top of the air conditioner to protect it from hail damage. Weigh the wood down safely with stones or bricks in case the wind gets stronger.
Don’t run your air conditioner while it’s flooded with water. Doing so may lead to an electrical shock hazard or possibly destroy the internal system components.
To avoid these issues, disconnect the power to the air conditioner and thermostat. The easiest method for completing this is to find 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.
Once the rain moves on, you want your system to dry out quickly. Remove standing water, if possible, and clean any debris from the immediate area.
Don’t turn on the system until it has been evaluated by an HVAC expert. Even after it has dried out, using flood-damaged equipment could pose the same hazards as using the air conditioning while it’s still underwater. Some issues require days or weeks to begin having symptoms, so it’s best to keep your air conditioner turned off until you get the all-clear from an HVAC pro.
While you wait for your service visit, review your homeowner’s insurance policy to see if flood damage covers your outdoor air conditioning system. If so, take pictures of the damage and process your claim right away. If you don’t have flood insurance, you might still be covered if the system has suffered wind or hail damage.
