How to protect your outdoor HVAC

As the months begin to cool, many people’s air conditioners go off while their heat kicks on instead. Although your system may be getting a rest, it can undergo damage throughout the fall and winter. Between falling leaves and debris as well as icy snow, without proper protection, your outdoor unit can take a serious beating. We have gathered some essential tips for you to follow to protect your outdoor HVAC system.

Clean your outdoor HVAC

At the end of the summer, when your air conditioning is turned off, you should clean the system. By opening the unit, you can clean out any debris, such as leaves and sticks. Throughout autumn, while leaves are falling, you should consistently clean your system so that leaves do not build up. You can clean the fans, vents, and other unit parts. However, you should turn the power off beforehand to mitigate any hazards.

You can also inspect your system while cleaning it out. If you discover any leakage during your cleaning, you should contact your local HVAC repairman to properly fix the unit.

Clear the surrounding area

Surrounding plants can lead to an accumulation of debris in your HVAC system. As plants begin to die off in the fall, you can cut them back to limit the impact of fallen leaves and growth on the unit. Additionally, as you perform your final yard mows of the year, you should cover your system to protect it from tiny shards of grass.

Maintenance HVAC work
