I just had my HVAC maintenance yesterday. they said there was "microbial growth" (mold) on the blower unit. They cleaned it off but recommended a UV light that "might" fix the issue. They wanted $850 for it. Looks similar to what the OP posted. I'd love to hear from some PROs on whether this is snake oil, or if it's actually worth the spend. Is this something a competent DIY can do?[/QUOTE]
From what I read it can be a DIY install and can be found on Amazon. But it appears they only warranty it if it’s professionally in installed ? In HVAC that “warranty thing” seems to be common. Maybe some day there will be class action on canceling the warranty. ( that’s a whole nother can of worms, let’s not go there)
