Air Conditioning – A/C Odor? Don’t Cover It Up, Remove It.
When the air conditioning (A/C) is operating, moisture condenses on cold surfaces inside the system. Most of this moisture drains harmlessly from the system; however, some moisture remains after the A/C is turned off. This moisture combines with air pollutants and contaminants to produce a musty odor, which is blown into the cabin when the A/C system is operated. Performing A/C maintenance (as shown below) will reduce the moisture buildup that causes A/C odors, and will inhibit regrowth of odor- causing microbes.
