Musty smell when air-conditoner is on...please help
I have been going insane trying to find this horrible musty smell in my house that has been intermittent. I finally made the connection to the musty smell, it happens when the air-conditioner is running. I do not run it often because we live in an area where we seldom need it. I have read about a drip pan or coils needing cleaning but my air-conditioner is central air. How do I or where to I look to clean this unit?
I have been running it for 2 days now because it has been very warm outside and the smell has subsided. Will this smell come back next time I need to run the air?
