There are two major parts to your HVAC system. The condenser is the outside unit and (thanks to its location) the part most susceptible to damage in extreme weather. Learn everything you need to know about operating your HVAC unit during severe weather and how you can best protect your system.

Severe Weather and Air Conditioning

Experts suggest that as global warming continues to worsen, the risk of inclement weather increases. Severe weather events such as thunderstorms aren’t too common in Oregon thanks to our pacific climate, but they can still occur. Increased precipitation from heavy rain can lead to flooding and landslides, which are a direct threat to your home.

How to Protect Your HVAC Condenser

Preparation is the best method for preventing damage due to extreme weather.

  • Heavy rains and storms - Cover your condenser with a tarp to help protect it from large quantities of water. Make sure to remove the tarp soon after the storm has passed, as a tarp creates the perfect environment for mold, mildew, and pests to thrive.
  • High winds - Clear your yard of decor, tools, and debris. High winds are categorized as those moving at least 58 MPH and lasting for over an hour—which is plenty of time for loose items to cause damage to your HVAC system.

Is it safe to run AC during a storm?

Many homeowners wonder whether it’s safe to operate their system in a storm. Typically, you can keep your air conditioner running during a storm, but with many kinds of inclement weather, there is a risk of a power outage. If you do lose power, turn your HVAC system off at the breaker to reduce the risk of a power surge when the power returns.
