How To Properly Maintain A Window Air Conditioning Unit

Window air conditioning units are designed to provide climate control to a single room. Proper and regular maintenance of your air conditioning unit can both extend the lifespan of your air conditioner and improve its efficiency. By performing maintenance on your window air conditioning unit every few months, you can ensure that it is working as it should

How to Maintain a Window Air Conditioner

  • Air Filter: Depending on the model of air conditioner that you have, you will either have a disposable or a reusable air filter. This filter will keep dust and other debris out of the inner workings of your air conditioner, and will become clogged over time. Replace the filter if it is disposable, or wash it with soap and water if it is reusable, once a month during times of heavy usage, and before starting the air conditioner up after cold months. Check the owner's manual for specific directions on which type of filter your unit uses and how to properly remove it.
  • Coils: Air conditioners cool air through a series of electrified coils within the actual air conditioner. Over time, dust will build up, and they will need to be cleaned out. The coils can be reached by unscrewing the cover of the air conditioner, which will require a screwdriver. Use a duster or a small brush to clean this area out every time you replace or wash the air filter. A vacuum cleaner also works well and can help you clean out the coils much faster than by hand.
  • Fan: A loose fan in an air conditioner is a common reason for loud noises during operation or for decreased power. Simply use a screwdriver to open up the air conditioner's cabinet, and tighten the screw located in the middle of the fan to fasten the fan securely to the motor shaft. This does not have to be done regularly, but should be done at the start of every period of heavy usage to ensure that your air conditioner is working properly.
  • Drains: The drains in your air conditioner can become clogged, which can cause leaks to develop. The drainage ports are most commonly located on the bottom of the unit, but will depend on the model of your air conditioner. A wire brush or steel wool works best to prevent gunk and other debris from building up in the drains, and ensures that your air conditioner does not leak. Drain cleaning should be completed once a month during times of heavy use.
