Preparing Your AC for the Off-Season: What You Need to Know

Preparing Your AC for the Off-Season: What You Need to KnowYour AC unit has been working hard all summer long, keeping you cool and comfortable during the hottest days of the year. As the temperatures start to drop and the cooler weather sets in, it’s time to start thinking about preparing your AC unit for the off-season. Taking care of your air conditioning system during the winter months is important to ensure it stays in good condition and is ready to go when the warmer weather returns.

Here are some tips on how to maintain your AC unit during the off-season:

Clean the Filters

Keeping your air filters clean is important all year round, whether or not you are using your AC unit. Dirty filters can cause your unit to freeze up and can reduce its efficiency. Cleaning or replacing your filters on a regular basis is a simple and effective way to keep your AC unit running smoothly.

Seal Window Frames

If you have a window AC unit, it’s important to check the seals around the window and the unit itself. Sealing any gaps or leaks can help prevent air from escaping your home, which will improve the efficiency of your AC unit. You can use weather stripping or caulking to seal any gaps.

Remove Debris From the Outside AC Unit

It’s important to keep the area around your outside AC unit clean and free of any debris. Leaves, grass, twigs, and other items can easily accumulate around the unit, which can cause it to malfunction or even break down. Regularly cleaning the area around the unit will help it function properly.

Coil Cleaning

Cleaning your AC unit’s cooling coils is another important part of off-season maintenance. Dirty coils can cause your unit to work harder than necessary, which can increase your energy bills. Regular cleaning of the coils can keep your AC unit functioning at peak efficiency.

Cover the Unit

In some cases, it may be a good idea to cover your AC unit during the off-season. Covering your AC unit can protect it from harsh winter conditions and also prevent debris and dirt from accumulating. If you have a window AC unit, you may want to remove it and store it somewhere safe until you need it again.


Taking advantage of your AC company’s maintenance plan is a great way to prepare your AC unit for the off-season. A technician can come out and do a routine inspection of your AC unit, giving you tips and ideas on how to care for it during the colder months. This can help you protect your AC unit during the off-season and ensure it is ready to go when you need it again.

Remember, a little care and maintenance during the off-season can go a long way in preserving the life of your AC unit.
