During the summertime, many air conditioners in Tennessee are running around the clock to keep indoor spaces cool and comfortable. But in the wintertime, these units tend to sit idly and unprotected—which can cause problems that require air conditioner repair near Murfreesboro later on. Fortunately, providing adequate AC maintenance during the winter can help protect your air conditioner. You can learn more about how to prepare your HVAC units for the winter in this article. 
Locate the Circuit
The air conditioning circuit is located near the unit. It typically has a plastic or metal lid, which covers the electrical circuit. After you locate and open the lid, flip the switch to turn the AC unit off. This keeps the air conditioner from turning on during a warm winter day, which helps keep water out of the unit that could freeze later on.
Wash the AC Unit
Over time, HVAC units collect debris such as bugs, dirt, dust, bird droppings, leaves, grass clippings, and twigs. Clean the unit thoroughly by washing it with a hose. Be sure to let it dry completely before using the unit.
Insulate Ductwork
Fit any pipes exposed to the outside air with foam pipe covers. The foam should be cut to fit the exact length and circumference of the pipe. This will help protect the ducts from freezing temperatures. It’s fine to leave the foam covers on the AC pipes year round.
Cover the AC Unit
Protect the HVAC unit with a waterproof cover made from plastic or vinyl. You can buy any type of covering to fit your unit, or contact an AC service specialist for a cover that is designed specifically for your AC unit. Wrap the cover with vinyl ropes or bungee cords to keep it securely attached. Check the AC unit each week to be sure the cover is still secure. Remove leaves, snow, water, ice, twigs, and other buildup from the cover.
