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?




“Mine” was a poor choice of words. I didn’t install a UV light, but I did install an air Ionizer. My point wasn’t clear: asking your HVAC tech for advice, since they service your system, I presume, and may have additional details like install pointers or potential impacts on warranties, etc.
