Does snow hurt your air conditioning unit?
Air conditioners are built with a sturdy metal covering to resist the elements, including wind, rain, heat, and snow. They are installed outside and are therefore made to withstand harsh weather.
Should I cover my AC unit during winter?
It may seem logical to put a cover over your AC system to prevent moisture from damaging the unit. However, there is no way to prevent moisture from getting inside. A cover will trap moisture, encouraging the growth of mold and mildew. Moisture can also cause your system to rust which can affect the parts inside and keep it from working correctly.
Another issue with using a cover is that it attracts critters. Animals like mice and squirrels may find a warm retreat from the cold underneath, causing a whole other set of problems.
How do I winterize my AC unit?
While it’s true that your AC system is built to withstand harsh conditions, it is still essential to winterize your system. During the fall and winter months, leaves, water, and debris can clog and rust mechanical parts of your system. To protect it, you need to winterize it each year. How do you do this? Here are some tips:
- Turn the power off – There is a switch on each AC system that turns off the power. It’s typically located under a plastic or metal lid. Turning the power off will prevent it from turning on during a warm day, which will keep water out of the unit that could freeze overnight and damage mechanical components.
- Clean the unit – Dirt and debris collect around the AC unit in the summer and fall months. Clean any gunk off of it with a clean wet cloth. Remove sticks and leaves near the unit to prevent critters from burrowing underneath.
- Insulate the pipes – It’s a good idea to cover the pipes of your AC system. If you don’t, they can freeze and burst when the temperature drops. You can use foam pipe covers and duct tape to keep it in place.
- Check on it periodically – After a major snow or ice storm, it’s good to check on it to ensure nothing is damaged.
