The Truth About Condenser Covers: Good or Bad?

Condenser covered with snow does not need a condenser cover



As the snow begins to fall and the temperatures dip here in Massachusetts, many

homeowners take extra precaution to protect their Central Air Systems. Many think its a necessity to keep your outdoor condenser safe from the harsh elements it will encounter. One thought is to purchase a Condenser Cover, which snuggly wraps around your condenser in a warm, safe surrounding. The truth about condenser covers is that they are NOT recommended to cover your outdoor condenser during the winter. In the post below, we'll tell you why.


  1. Trapped Moisture: When you wrap your condenser through the winter, you run the risk of moisture and condensation forming within. It creates a sealed environment with little to no proper ventilation. As a result, this moisture leads to rust and corrosion of the vital components within the condenser, such as the coils. 

  2. Inviting Rodents and Critters In: Condenser covers can inadvertently create a warm, cozy home for rodents and critters during the cold winter months. They can create an immense amount of damage by as chewing though electrical wiring, insulation, and other components. There nests can also severely clog the interior components and cause system failure if they go unnoticed.

  3. Voided Warranty: Many HVAC manufacturers include specific guidelines in their warranties that prohibit the use of condenser covers. Using a cover may void your HVAC system's warranty, leaving you responsible for any repairs or replacements that may be needed. Manufactures also will not warranty any damage caused by rodents.

So, what can you do to protect your system?

These systems are created to withstand the elements they were intended to be in. If you are still concerned with snow accumulating on top of the condenser, your could use a simple lid. A thin piece of plywood with a brick placed on top to prevent from blowing away will do. A more esthetically pleasing option would be a 3rd party lid that covers only the top. Be sure to check your measurements before ordering!


Have a Heat Pump?

NEVER under any circumstance place a cover or lid on the outdoor condenser. These units are designed to be in use year round for cooling AND Heating. Placing any cover on them while operational can cause serious damage.


If you have any questions or concerns about your HVAC system's winter readiness, don't hesitate to give Dodge Cooling and Heating a call.
