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’m no expert, but I am handy.

    I called my HVAC technician before, and he told me to install mine in the chamber after that one. I have one before it splits.

    Call your HVAC technician and ask them for over the phone advice. My tech offered to install mine for free on my next service.

    I still did mine, and he checked my work and okayed it as “a gold star install.”

    Here is a picture after I installed it and before wiring it.

    Here is a picture after I installed it and still haven’t wired it yet.

    Edit: I don’t have a finished photo, but I will post one on request. I’m too lazy to take a photo and explain why if my wife asks.

      What do you mean by “ before it splits?” I’m still learning a lot, but the general consensus of where to place the UV light was on the bottom side of the A-frame, because that’s where the moisture will accumulate and allow for bacteria and fungus growth.

      I ended up drilling a hole and mounting the light right into that end plate, and then drilling another hole in my new access panel for the cord, and putting duct putty around the hole.
