I am adding a UV light to my furnace coils. I decided to cut an access panel for easier cleaning and access to the UV light. I did not realize there were these triangular end covers for the A-frame of the furnace evaporator coils.
I don’t see them anywhere online when looking up diagrams of furnace coils. When I search online, it is also not clear if these covers are necessary. Are these covers beneficial? Or can I take one side off to fit the UV light underneath the A-frame?




I had it on for a few days straight and it didnt smell at all. But I think to be safe, I’m going to keep it unplugged and then run it for couple of hours each month (with the furnace turned off).
