Winter is already here, and while it’s more of a necessity instead of a luxury in any home during summer, you may not need it in winter. Even though statistics show that about three-quarters of US homes have central air conditioners, there are millions of homes that rely on window ACs to keep their homes cool too. So, is it okay to leave the air conditioner in the window during winter?
This article will help you answer this question. Also, you’ll learn how to store your window AC during winter to ensure it’s in the best condition to serve your home next summer.
Can You Leave Your AC In The Window During Winter?
During winter, it’s advisable to remove your window air conditioner and store it well. This protects it from freezing temperatures, snow, wind, and rain, damaging the AC.
For example, water from the snow, ice, and rain damages your AC’s electrics. Ice and snow might freeze up the coils inside your air conditioner. While you can fix this next summer, these frozen coils will likely cause permanent damage.
In addition, the freezing temperatures can cause the lubricant to thicken. This can damage your air conditioner.
It’s worth mentioning that leaving your window AC outside uninsulated is not suitable for your heating efficiency and energy bills. It’ll act as a cold spot in your home, resulting in increased energy consumption.
Also, don’t leave this handy home equipment in place once the temperatures hit below 60F. It’s better to unmount and store it properly and seal the window completely.
