YouTube video (Derek Cole) explaining an HVAC preventive tip: when hot air flows over cold AC coils it causes condensation that can collect in drain pans, creating a damp, dark environment where microbes grow. The speaker recommends introducing UV exposure (or sun-drying removable mats) to clean and dry components so microbial growth is inhibited.
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 way to prevent that from happening is to introduce UV into that system somehow. 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?
