Step 1

You first need to find the source of the bad odor. You can check the filter, drain pan, drain lines, or the inside of the air conditioner. Look for obvious signs first because something such as a dead mouse or mold can be the cause of a bad odor. Remember to unplug the air conditioner unit before you begin to clean or do any work to the air conditioning unit.

Step 2

If you discover that the cause of the odor is your filter you can clean your filter or purchase a new one. Most air conditioning units have reusable air filters that just need to be washed and dried to keep them clean. To clean one you can use warm soapy water and diluted bleach solution. You might want to clean it a few times if it is really dirty before putting it back in. Be sure that there are no signs of mold or mildew because if there are it is sure to be your source of air conditioner odors.

Step 3

Always check your drain pan. If old water has been sitting in the drain pan it can get moldy and cause a really bad odor. You can easily clean your drain pan with warm soapy water using dish detergent. You can then rinse the drain pan with diluted bleach or a vinegar solution. Allow the drain pan to dry completely before putting it back in place.

Step 4

You can also check the condensation drain line to see if that is the cause of the odor coming from your unit. You can flush the drain line with bleach and hot water. Generally in window units you will not have a drain line that can be removed to be cleaned, but you can use a pipe cleaner or toothbrush to clean the parts that you can reach.


Clean the entire unit. You can wipe down your entire air conditioning unit to be sure that there is no mold or mildew on it. Especially check the air vents to be sure that there is no mold or mildew.

These are five easy steps to remove odors from your air conditioning unit. If you do not feel comfortable working on your air conditioner you should call a professional.
