Turn the Power Off
Before performing any kind of maintenance or cleaning, make sure to shut off the power to the unit. You can turn off the unit by switching off the power at the electrical circuit. The circuit usually has a plastic or metal lid.
Shutting the unit off ensures it won’t turn on when you’re working with it. This also prevents the unit from starting on a warm winter day, which could lead to water forming in the unit, freezing overnight, and causing internal damage.
*We recommend contacting an HVAC technician to perform any maintenance or repairs.
Clean Your Condenser
Clear any dirt, dust, and debris from around the condenser. This includes twigs, leaves, plastic wrappers, and grass clippings. After shutting off the power to the unit, a professional may wash away dirt, bugs, and other debris with potential to clog the unit.
Cover the Unit
Many units were designed to withstand extreme weather so this topic remains hotly debated, but you can choose to cover your unit during the winter. This helps keep out snow, rain, and ice that may cause damage.
Many manufacturers design covers just for this purpose but tread lightly. Often, animals can hibernate in the cover, and condensation or moisture can form. This can lead to rust or corrosion and cause damage.
Instead, cover only the top of the condenser to prevent falling ice, snow, hail, or other precipitation from getting inside. Choose a cover that allows the system to breath and won’t trap in moisture.
Check the Unit
During the winter, make sure to check the unit weekly. Clear any snow or ice that accumulates. Check for any debris inside the unit like branches, leaves, and animal nests. Remove any debris around the unit and adjust the cover as needed.
