AC Smelling Bad? Dirty Sock Syndrome May Be the Culprit

Ahhh, the first signs of a hot summer day appear and right away we turn on our trust air conditioning system.  A handful of folks might notice an awful smell permeating throughout the house- Is it mold? Mildew? Dirty socks? Why does the entire house smell like the Raider’s locker room after a game that goes into overtime?

This problem is not so unusual and it actually has a fitting name that us HVAC contractors have entitled “Dirty Sock Syndrome.”

Why Do I Have Dirty Sock Syndrome?

Dirty Sock Syndrome occurs when organic matter such as moisture, mold, and dust accumulate on your AC system’s evaporator coil.  These contaminants then breed bacteria and mold and get pushed through the ducting system and into your living space.

Dirty Sock Syndrome typically occurs during the spring — when your AC system is not running these particles of moisture, dust, and dirt have more time to accumulate on the evaporator coil in between cycles. If you cool and heat your home with a heat pump, you may see this problem crop up in the fall as well.
