Most homeowners couldn’t bear a hot and humid summer without turning up their AC and believe air conditioning is one of humanity’s greatest inventions. However, some homeowners neglect their incredible AC units when the cold, bitter air arrives. If you want your cooling system to run like a dream when you need it most, then check out these HVAC winter tips to avoid expensive AC repair costs come spring.
Don’t Cover the Outdoor Unit
This sounds logical that the outdoor air conditioning unit needs a cover to protect the appliance from snow, sleet and more. However, HVAC experts say, “Don’t cover an outdoor AC unit.” A cover restricts airflow, causing moisture buildup inside, which can lead to the formation of mold and rust.
Not only that, but covering an outdoor air conditioning unit can invite small animals like mice and squirrels to move in for the winter. They’ll crawl under the cover and can cause electrical damage as they use the wires to build a nest.
Remove Portable AC Units
Many homeowners take down the AC units they have around the house to prepare for the winter season. There are good reasons to do this. For one, it keeps the cold, drafty air out. Also, removal can extend the life of your AC units and protect them from ice and snow buildup that can cause damage.
HVAC professionals recommend removing a portable unit from the window, ideally before the first frost of the year. Then, store it in a clean, dry location, such as the basement, placing it in an upright position to avoid compressor damage.
Don’t Run the AC During Winter
Don’t turn on your air conditioner in winter, even if you have a house full of guests and it’s getting warm inside. Most AC units are not designed to operate in cold weather, and this can result in a frozen evaporator coil. If this occurs, the air can’t flow through the unit, and a block of ice can form. This will be a costly repair, and that’s not the end of it.
According to HVAC experts, the evaporator coil sits on top of the furnace and passes through the ductwork to the outdoor unit. When the heat is turned back on, all the ice will melt and potentially damage the furnace’s components.
