But has to be done. Our unit is 14 years old and is a cheap one. This house was a Rental for several years. My Wife rented for a couple before we Married. She has MUCH better smell than me and she has noticed a "dirty sock" smell off and on with our unit the last 3-4 years. This last Summer, it had to work REALLY hard to cool. We are also adding two intakes in the house to help with air flow.
