“Locker Room” smell
That all-too-familiar “dirty sock smell” might not actually be coming from your husband’s gym bag. Instead, this home odor problem could be caused by a lot of buildup of bacteria on your heating system coils.
Bacterial growth can happen at any time of the year. But it’s especially predominant in the spring and autumn when the system continuously cycles between heat and cold.
Condensation on the coils forms the perfect environment for bacterial growth, which produces a distinct odor.
The best way to alleviate your home of the stink is to clean the evaporator coils with a non-acid coil cleaner or call a qualified HVAC professional to clean the air ducts and coils for you.
