An HVAC tech cautioned the use of UV lights in my system because my
aircon candenstion pan is plastic and my humidifier has plastic parts,
both of which he said will deteriorate because of the UV lights. Any
truth to this? Any solutions?

Thanks.

It depends...on whether the plastic using in the drain pan and
humidifier are UV resistant or not.

Install it in the return.....it is only when the UV comes in direct contact
with non-UV resistant plastic

The disadvantage there is the UV doesn't strike the coil.

Interesting post!

I wonder if you can put like a UV protecting coating, say Polyurethane on it
before installation. Never ever thought of this before. However, we put the
lights in the return air or downstream, never enough room to put them over
the coil.
