Can Rain Damage Your Outdoor Unit?

August 29, 2023 | Blog

Your outdoor HVAC system is designed to weather the elements. Light rain itself isn’t harmful to your unit, but the weather patterns that come alongside it can create a different outcome. Knowing how to take care of your outdoor air conditioner will prevent damage to the machinery and maximize indoor comfort!

Heblon Heating & Air Conditioning is honored to have served Meridian and surrounding areas for over 20 years. With the help of our team’s knowledge and experience, you can rest assured that your home comfort is our top priority. Read ahead to learn how poor weather can affect your outdoor system and what precautions can be taken to prevent these issues.

How Is My Outdoor AC Safe From Rain?

Thankfully, there aren’t many risks of rain damage to outdoor units. You may wonder how your air conditioner is protected by bouts of light rain. Even though the machinery is made up of electrical and mechanical components, its insulation protects the parts from experiencing damage.

It may come as a surprise, but a little bit of rain can actually benefit your system. Vegetation and dirt can become lodged within the unit. This obstruction can negatively affect its performance. You can spray the unit with a hose to dislodge debris in periods with little rain to rectify this issue.

What Weather Can Damage My Outdoor Unit?

Rain is often associated with other forms of poor weather. A few outdoor conditions can cause damage to your system if preventative action is not taken. Knowing the weather that affects your system will prevent damage from occurring in the future.


Consistent heavy rains can be problematic for your outdoor system. Mississippi occasionally experiences flooding in select areas, including Meridian. Excess moisture can cause the components to malfunction.

Flooding can also create a hazardous breeding ground for mold and mildew in your system, compromising your indoor air quality. A cement platform can be used to elevate the machinery, protecting it from water buildup.

Heavy Wind And Tornadoes

Strong winds and occasionally tornadoes can be a side effect of many storms. Heavy winds can pick up all kinds of twigs, leaves and other debris that can damage your unit. Outdoor patio furniture can also slam into the machinery if not removed. If surrounding objects and vegetation hit the system, it may compromise its performance.

Tornadoes and other strong winds can also pick up your outdoor air conditioner if it’s not secured. You can prevent these issues by fastening it with hurricane straps and covering it with a breathable material. However, it’s crucial to remove any coverings once the winds subside. Failure to do so can cause moisture to form inside the machinery.

Weather Any Storm With Meridian AC Repairs

There’s peace of mind knowing that your air conditioner is durable enough to outlast minor weather conditions. However, it’s crucial to take the proper precautions with the threat of hazardous outdoor conditions.

What Our Customers Are Saying

Highly Recommend Using Heblon

My AC wouldn’t turn on so I called Heblon . It was a Sunday and from calling the office to the engineer arriving took about 45 minutes. The engineer was professional and gave me excellent feedback on the issue. Repaired within 45 minutes and couldn’t ask for more. Highly recommend using Heblon, and will definitely be using them from now on.
