How To Maintain Your Air Conditioning Units

For Content

Air conditioning units can last a long time, as long as they are properly taken care of. Fortunately, there are many things that you and HomeSmart Xcel Energy can to make sure that your air conditioner continues to run smoothly.

Clean or Replace Air Filters

One of the most important parts of the air conditioner is the filter. The filter facilitates the airflow process by making sure that environmental particles are not flowing through the machine and causing it to run less efficiently.

Clean your air filter every 1-2 months for the best efficiency. Some air filters are disposable and you simply replace the filter with a new one. Others are permanent, and you can clean them by using a soapy rag to gently rinse them.

Clean the Drains

If you've ever had your carpets become discolored from the water dripping out of your air conditioning unit, then you definitely need to clean out your condensate drains. Take a stiff wire or pipe cleaner and insert it into the drain channels, which are usually on the bottom of the unit, in order to clean out dirt and debris.

Check the Window Seal

Your air conditioning unit runs most efficiently in an enclosed space, so don't let your window seal develop cracks. Your air conditioner will have to run harder in order to cool the same area, and this can cause wear and tear over time. There are do-it-yourself sealing kits at most home improvement stores. You simply spray a foam substance onto the window seal and it hardens to form a durable seal.

Prepare for Inclement Weather

Do your air conditioner a favor and protect it from the cooler seasons. You can do this by removing the unit from your window and placing it in a dry, room-temperature space, or by placing a cover over it during the winter months. If you leave your air conditioner exposed to the elements, debris and dust can collect in the unit. Winter weather is also hard on the coils of your air conditioning unit.


Taking care of your air conditioner only takes a few hours per year, but it can save you a lot on cooling costs and keep your air conditioning unit alive for many more years. In addition to the steps above, you can take good care of your air conditioning unit simply by using common sense; keep the unit clean and free from obstructions in order to keep it running happily in the long term.
