With more frequent violent storms, tornadoes, hurricanes, and flash flooding making headlines across the U.S., protecting your home’s outdoor air conditioning unit(s) is more critical than ever. In many coastal regions, lifting AC units high off the ground to protect from water damage is commonplace, but increasingly powerful displays from Mother Nature mean inland customers are as equally concerned about weather-related risks to exposed air conditioning units, as well.

  1. Regular Maintenance and Inspection: Before you worry about protecting the outside of your AC units, make sure everything is good to go inside. Schedule your One Hour Heating and Air expert to inspect, clean, and service your AC unit before the demanding summer season. This helps to identify potential problems early and ensures the unit is operating efficiently. Once the unit is in optimal performance condition, steps can be taken to bolster its defenses against spring and summer severe weather.
  2. Protective Coverings: These are one of the most effective ways to protect your AC unit from the elements. They can shield the unit from debris, dirt, and other environmental factors that can cause damage. However, it's important to use these covers appropriately and purchase ones that are designed for this purpose. For example, covering the unit during the winter months, when it's not in use is different than using the same cover in warmer months when trapped moisture can cause rust and mold. Look for covers made of breathable material that can protect the unit without causing other issues.  Feel free to call us at One Hour Heating and Air for suggestions! 
  3. Positioning and Shelter: Proper positioning of your AC unit can significantly reduce its exposure to harsh weather. If possible, place the unit in a shaded area to protect it from direct sunlight, which can cause overheating and reduce efficiency. Additionally, consider installing a shelter or awning over the unit that provides adequate airflow and protection from rain, snow, and falling debris. This should include securing the unit to a base, such as a concrete pad, to make it less vulnerable to high winds. 
  4. Flood Protection: We touched on this briefly above, but it bears repeating. If your home is in a flood-prone area, getting your AC up and away from water intrusion is crucial. Elevate the unit on a platform above the expected flood level to prevent water damage. Double-check that the platform is sturdy and secure, perhaps with the addition of a sump pump in areas where water accumulation is common to keep the unit dry.
  5. Debris Management: Leaves, branches, and other yard waste can clog the unit, reducing its efficiency and potentially causing damage. Regularly clear the area around the unit and trim back any vegetation that is too close. A clear perimeter of at least two feet around the unit is recommended to ensure proper airflow and reduce the risk of debris accumulation.
  6. Protection from Snow and Ice: During winter months, snow buildup can block airflow and put undue stress on the unit. To prevent this, regularly clear snow and ice accumulation that can damage the coils and other components. Having a cover or shelter, as mentioned above, will improve your AC units’ protection all year round.
  7. Lightning and Electrical Surges: Install a surge protector specifically designed for outdoor AC units. This device can prevent voltage spikes from damaging the unit's internal components. Additionally, during severe storms, it may be prudent to turn off the unit at the breaker to prevent damage from electrical surges.
  8. Monitoring and Technology: Smart thermostats and monitoring systems can alert you to potential issues, such as abnormal temperature fluctuations or operational problems. These systems can provide real-time data and alerts, allowing you to take prompt action to protect your unit. Some advanced systems can even be integrated with weather alerts to provide warnings about approaching severe weather.
  9. Insurance and Warranties: This may be one of the most important items on the list! Ensure that your homeowner's insurance policy covers damage to the AC unit from natural disasters and severe weather. Additionally, investing in a comprehensive warranty or maintenance plan can provide peace of mind and financial protection in case of unexpected damage.
