Derek Cole from One Hour Heating and Air Conditioning explains that musty smells from HVAC systems come from mold and mildew growing in stagnant water that collects in the drain pan under cold evaporator coils. He recommends installing a UV coil scrubber to kill the microbes and stop the smell.

Derek talks about that musty smell that you smell coming from your system sometimes. Derek, what exactly causes that musty smell? And is there anything that you can do about that?
In air conditioning, you have to remove moisture to get humidity out of there. Air conditioning is all about removing heat, right? So you're taking heat out of the air. It's going over a cold coil which has refrigerant in it, and then it's coming back out cooler air than what came in. So the byproduct of that is water. So that's why you have drain lines. That's why you see water dripping outside. So what will happen is when you have that hot air going across that cold coil, you get condensation and that's going to drip down to the drain pan. Well, if that drain pan is not draining or something is the matter, things will start growing in that drain pan because you have cold water sitting in a damp, dark spot. So the thing that happens is growth, right? If it's not in the air or if it's a bug or it's a virus or whatever it is, it's going to die and it's going to sit at the bottom in that drain pan for a period of time. So you start getting the first time you turn on your heat or your air conditioning especially, you get that kind of damp, musty, moldy kind of smell. Way to prevent that from happening is to introduce UV into that system somehow. Now we do it here with the coil scrubber, which shines on the indoor coil, has the UV power. So nothing can grow in uv. If you want to prove that point, everybody at home has that mat at the front or back of the house that has the mildew and it's kind of wet and it's kind of damp. Take that mat, stick it out in the middle of the yard in the sunshine for a period of time, and that will be clean and dry. Because nothing can grow when UV is present, right? So in the indoor air environment, in the air handler that is not present. So we have to make it present with UV light. UV light will solve that problem. So the same power, the sun, or same energy that holds, we can bring it into your system and that'll stop that damp, musty smell.
