A short instructional clip explaining why air conditioners can produce a musty, damp-sock smell: as AC coils cool incoming air they condense moisture that collects in drain pans, and if the drain pan doesn't drain the standing damp water in dark conditions fosters microbial growth that creates the musty odor.

Yeah musty is that kind of wet, damp, dirty socks, bottom of the hamper kind of smell. So that is musty. The reason it smells that way is because in air conditioning you have to remove moisture to get humidity out of there. So air conditioning is all about removing heat right? So you're taking heat out of the air it's going over a cold coil which has refrigerant in it and then it's coming back out cooler air than what came in. So the byproduct of that is water. So that's why you have drain lines that's why you see water dripping outside. So what will happen is when you have that hot air going across that cold coil you get condensation and that's going to drip down to the drain pan. Well if that drain pan is not draining or something is the matter things will start growing in that drain pan because you have cold water sitting in a damp dark spot. So the thing that happens is growth right? So even the.
