Does Rain Damage My HVAC Unit

With hurricanes and downpours moving into Georgia, you may ask yourself; "does the rain damage my HVAC unit?" The great news is that heating and air systemswater damage hvac unit are meant to withstand mild to medium weather conditions. They are designed to withstand the elements for years and years. Especially if your unit is a reputable brand that properly tests the equipment for wear and tear. Not to mention, a proper installation performed by a trained team of experts. (Like Guardian's team!)

While you may have peace of mind that the pop up shower will not damage your unit, there are some instances where you will want to have your system checked:


Remember your heating and air system is meant to withstand downpours and water. However, during a rain shower, the water drains out of the system as designed, and rolls over the access panels keeping the inside components dry. On the contrary, standing or pooling water can potentially damage your system. Remember that water has a way of getting into the nooks and crannies of areas while also creating rusting potential. Standing water can seep into closed components. Make sure to have your system checked if the water line reaches the access panels or lines.

Don't forget your inside unit when it comes to water. Have a water disaster inside your home where standing water affected your unit? (We often see this in basements) Make sure to have your system checked out right away. While there are safeties and drains in place, your inside unit


While the wind itself shouldn't damage your system, often times the fallen tree branches as a result of the wind can damage your unit. A banged up or dented system can impact the coil which will most certainly affect your system's operation. If extreme winds have moved your system, this too can not only create an unsafe situation but also damage your system. Potential electrical wires may have been pulled, and the line set may have become kinked. This absolutely requires a technician visit.


While your HVAC system does have an outer casing to protect the inner components, any dents or dings can impact the fragile coil inside. If the weather report is calling for potential hail, you can briefly protect the unit by covering it with a wooden structure. Keep in mind, this can impact your air flow. Remove the wood structure as soon as possible. Never use plastic bags or tarps to cover the unit. First, the flexibility may not provide adequate protection, Secondly, it most definitely will impact the airflow required.

While it is rare that lightning will strike your low lying heating and air unit, lightning can damage your home. A lightning strike on or near your home can cause power surges which can directly impact your system. Installing whole home surge protection is one way of preventing electrical damage. Most importantly, lightning is not the only surge potential we see. Power outages and electrical line variances can too impact your system.


You can laugh a little… we know that snow is not generally a concern during Georgia winters. However, in the event we do have a snowpocalypse again in Atlanta, the biggest concern is restrictive air flow. While we don't foresee 24″ of snow or more, having the outdoor unit surrounded or covered with snow can restrict the air. Keep in mind, if you have leaves, bushes etc.. surrounding your unit. This does also restrict that important air flow much like snow would.

The most important take aways from any inclement weather events is that your outdoor unit does tolerate the elements. However, any damage or restriction can create damage. Water is always a concern when dealing with electrical components but your largest concern should be standing and continuous water. Make sure to contact the experts at Guardian to evaluate your system and make sure it is operating properly and without damage in the event of severe weather conditions. Keep in mind, if any damage is found months after the inclement weather, it will be much more difficult to claim this on your homeowners insurance.
