Are you getting musty, dirty sock type air conditioner smells from your HVAC unit? If so, then you’ve come to the right place to find a solution, and get your home smelling so fresh and so clean.
The very first thing that you should check would be the air filter. That’s usually the cause of it. If the air filter is clogged and dirty, that may also mean that the evaporator coil is plugged, with dirt, dust, and possibly bacterial growth.
