According to the technician, the mold is something noted on virtually all Villages units. Curious on others experience and curious if anyone has installed one of the ultraviolet lights.

My HVAC maintenance company installed one in the duct above the HVAC unit. He showed my a photo he said showed the duct covered with black mold. I couldn’t read the photo. It cost me $3,500. Whether or not it works, I don’t know.
In a previous home, I had a well that had some e-coli contamination, and that was fixed with a UV light. That was a light tube close to 3 feet long that ran inside a stainless steel tube. There was perhaps a quarter inch between the light tube and the stainless steel tube. All the water ran through that space and was immediately sterilized. Then it went through a filter. The light tube had to be replaced yearly, and a buzzer went off when the year was past. The UV light I had installed here covers a much bigger area of air. It may not kill every mold spore going through the duct, but only the ones that are close enough. But it runs whenever the system runs, and the air recirculates, so it should gradually cut down the number of spores over a couple weeks and keep catching any that come through. But was I crazy? A sucker? Probably.
