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?
No, I don’t, and I’m sorry, I just have looked into it before myself, and once I looked into it, decided I wanted to avoid it completely, So my research stopped there.
I do have a UV bulb that I’ve glued into a tote so that I can sterilize things like my CPAP. After that I will air it out for a very long period of time to make sure that all of that stuff is gotten out.
One thing that I can tell you that I’ve learned from what I’ve researched is that the more air that flows over the bulb, the more ozone will be generated. So if it’s just sitting there not doing anything in still air and it’s producing a certain amount, having it in your AC unit might produce more. So that might be an angle you might want to look into.
Practically speaking for an AC unit, what I think would be really useful is to be able to turn it on at the beginning of the season to kill whatever bacteria might be in there, or to just be able to periodically turn it on.
Huh, I hadn’t thought about turning the light on for short periods. And if ozone is mostly generated with moving air, then turning the light on with the furnace off seems to be safest. Thanks for the suggestion.
If your intent is to sterilize the coils so that they can’t grow anything funky, then yes, probably that would be for the best.
Also, you could certainly test it by setting it to turn on when the furnace is on so you can see how stinky the ozone is. If it smells kind of strong, then that’s probably too much, right?
