Flooding or Hail Can Result in Big Damage to Your Air Conditioning System

Air conditioners are constructed to resist weather, including rain and snow. However, if your outdoor air conditioner is flooded with standing water from a large downpour, this could seriously damage the electrical components in it. Your cooling is most likely to get damaged if the floodwater rises above a foot deep. Still, if the equipment has flooded at all, reach out to Bob Brown Service Experts at 623-243-4517 for an air conditioning inspection.

If severe flooding has happened or is likely to happen, follow these instructions to avoid damaging your HVAC system or creating dangerous operating conditions.

Before Flooding

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

If you live in a flood-prone spot, research placing your air conditioner on a high base. This elevates the unit 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 install a retaining wall around it. This technique can help you avoid air conditioner flooding, even as water flows around it. Similarly, you can pile sandbags around the unit when you are alerted a storm is approaching.

If hail is in the forecast, you can lay 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 gets stronger.

During Flooding

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

To prevent these issues, switch off the power to the AC and thermostat. The easiest method for accomplishing this is to find the HVAC and thermostat breakers in your junction box and turn them to the “off” position. If you require help, get in touch with an air conditioning service company like Bob Brown Service Experts.

After Flooding

Once the rain subsides, you want your AC to dry out quickly. Draw away standing water, if possible, and clean any debris from the surrounding area.

Don’t start the system until it has been evaluated by an HVAC technician. Even after it has dried out, operating flood-damaged equipment might pose the same hazards as turning on the air conditioning while it’s still under the water. Some troubles require days or weeks to begin revealing symptoms, so it’s wise to keep your air conditioner turned off until you have the all-clear from an HVAC technician.

While you wait for your technician to arrive, review your homeowner’s insurance policy to see if flood damage covers your outdoor cooling system. If so, take stock 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 sustained wind or hail damage.
