A young tech pops up in a face-cam corner, pulling disgusted faces, over close-ups of the inside of an air handler. The camera lingers on rusted electric heat strip coils and a wiring harness coated in grime.
He calls what's on the wires and in the supply biological growth, and says that's why the day's job is a coil and blower motor clean-out, including the drain pan. Left alone, he says, it just spreads.
The last step is a UV bulb mounted inside the unit, aimed to keep killing germs on the coil after it's clean.
You guys want to see something nasty? Oh yeah, man. That's rough. It's real rough.
And that's exactly why we're doing a coil and a motor clean out. You get stuff like this growing all over your wires. This is stuff that you see right there. Inside right there there in the supply.
This biological growth. And I was cleaning up this part right here, the pan as well. Because if you don't clean that stuff up, you know, kind of like a disease, like a sickness, it just spreads. And this is exactly what happened in there.
It's not good. So, what we're doing for the day, nice, simple, and easy, it's going to get done just right. We got this UV bulb right here. Essentially, this guy over here is going to go ahead and install into the machine itself, the unit.
It's going to kill all the nasty bad germs. Essentially, just burn them off. So, nothing else spreads. That's the plan for the day.
Musty smells when the AC starts, weak airflow, an AC that runs longer than it used to, or a coil that freezes up are common signs. A tech can open the air handler and look at the coil face, the drain pan and the blower. If the coil face is matted with dust, it needs cleaning.
