where did they install it? between the air filter and the coils? or past the coils in the air handler?

in the supply before it hits the main trunk line
eta: it ties in to existing electrical panel and magnetizes to the top of the supply plenum box

UV light needs a certain length of contract time to kill anything. How long do you think it takes to blow past a certain spot in a vent shaft?
Funny stuff. It’s not there to kill stuff in the air; it’s to kill stuff growing in the duct and on the coils.

I think that was the point. UV lights work to prevent growth on coils but they do not kill airborn viruses because there is not enough interaction time/high enough density.
UV lights are currently being pushed as ways to disinfect the air in home HVAC systems.

Our HVAC technician came out yesterday for our fall/winter service check-up. The blower motor for our upstairs unit is leaking some fluid, so they will be coming back out to replace it.
He mentioned that they are currently running a "deal" on installing UV lights in systems to help with bacteria, mold, pollen, etc. Cost would be $591 for a double bulb in the upstairs unit, or $823 for a single bulb in the upstairs and downstairs system.
I know that UV light has been proven to kill certain bacteria and fungi, but do they do enough to warrant putting them in the HVAC system? If so, where do these costs line up?
Waste of money and to actually maintain anti-microbial effects, the bulbs will need to be changed extremely frequently.
In laboratory safety hoods, the UV bulbs are (or should be) tested monthly and are replaced at least every 6 months.

I put a uv light in my return based on a diy video. The light was cheap. I think total price was around 75 the hardest part was running electric and sealing that.
