Should You Cover Your HVAC Unit During Winter?

Winterizing HVAC Units

An HVAC professional can tell you that covering an outdoor unit isn't always needed. But, it's something that you can do if you want to make this a part of your seasonal routine. Before you decide if you want to cover your HVAC unit during winter, look at the pros and cons of doing so.

Advantages of Covering an Outdoor Unit During Winter

Covers designed for outdoor units are often affordable, so that's an advantage. Covering your unit protects the air conditioner coils as well. This means they'll likely run better the next time you're ready to run the AC part of your system.

A covered unit also protects against falling debris. This can be a good thing if your home is near a wooded area or in an area that's often exposed to high winds. A cover will also keep water from building up on coils and freezing when temperatures drop.

Reasons to Not Cover Your Unit Any Time

The best reason not to cover your outdoor unit in the winter is that manufacturers don't recommend it. A typical comfort system can withstand the elements well throughout the year. You may even have some issues with your warranty if damage occurs from a covered unit.

Additionally, covering your unit could create the perfect environment for mold growth. Trapped moisture could also affect your unit's wiring and other electrical components. Some other drawbacks associated with covering an outdoor unit include the following.

  • Preventing rain from keeping your outdoor unit clean.
  • Reducing natural drainage by blocking water runoff routes.
  • Providing a cozy spot for animals to nest during the winter months. This could damage wires and create a build up of feces and other debris.

It's Up to You

Now you know the advantages and disadvantages of covering a cooling unit in the winter. The final decision is now yours. But if you happen to have a heat pump, DO NOT cover the outdoor units. Heat pumps run year-round. Covering anything up is a fire and safety hazard!
