Are the plastic drain pans uv resistant in a new Luxaire a/c unit? i am considering having UV lights installed above the A coil and want to be sure it won't damage the plastic drain pan.
For what it is worth, most black plastics use carbon black as the colorant and it is also true that carbon black in sufficient concentration is a quite effective ultraviolet inhibitor in polyethylene. Pure polyethylene degrades quickly in UV. Black garbage bags have very little added. Other than assurances from the manufacturer, I know of no way to know for sure.
uvlight shouldn't reach pan.
the uv should be contained in the system.
you might consider mastic sealing ducts
and plenums and then you wouldn't need
uv lights to 'clean' the air.
4" pleated media filtes in an air tight
return is also a good investment
best of luck
I would go for home sealing including any recessed lights and duct sealing with a moderate 4" filter any day over uv. I have read and heard more than one story of expensive bulb prices, poor bulb lifespan, uv degradation of the bulb socket assembly/housing. If the ducts aren't sealed and cellulose insulation particles and other assorted dirt is being pulled in past the bulb(s) which are like dust magnets that degrade on output quickly when dirty.
You will in my opinion get the best bang for your buck and health with home sealing and a good filter. Do not go nuts and put a filter that is too restrictive.
"uvlight shouldn't reach pan.
the uv should be contained in the system."
It would appear they are worried about the primary plastic condensate pan under the evaporator coil, and UV light from bulbs in the plenum immediately above the coil could easily reach the pan under the coil while still being "contained in the system."
