This winter has been particularly severe, complete with a number of powerful arctic storm systems that have dumped foot after foot of snow in addition to bringing bitter cold single digit temperatures. As such, it's likely that the last thing on your mind has been your home's air conditioning system.

However, winter is the perfect time to get your home's air conditioning system in tip top shape for spring and summer. After all, in a few months you're likely to be complaining about the heat!

Therefore, it's important to practice preventative maintenance in order to keep your air conditioners and air conditioning systems running smoothly. In addition, it can help reduce energy costs by keeping them running efficiently. Here's how to get started.

Storage
Proper AC maintenance and storage is especially important for window units, as continued exposure to winter weather may hinder their performance come summer. After removing your window unit, it's important to store it in a cool and dry area of your home. You may want to cover it with a cloth or plastic sheet in order to keep dust and moisture out. While central AC systems don't require storage, it's important to keep the condenser unit -- which is outside the home -- clear and free from debris.

Filters
It's important to use a high quality air filter that will keep dirt and allergens out of the equipment and out of your air ducts. Maintaining a clean filter will prevent dirt from accumulating in your air ducts and circulating around your home. It's recommended that homeowners change their system's filter at least once per season. However, if you need a hand doing so, contact your local AC repair shop.

Check up
It doesn't hurt to schedule a tune up or inspection in order to ensure everything is working as it should. Your AC service technician will be able to identify any potential or developing problems and address any lingering concerns. You may be able to save on parts and labor if your unit or system is covered under a warranty.
