Ultraviolet Irradiation Light in A/C Unit? Good Science?
I am so new to the concept of central AC (this is my first house with central AC) that I wonder if any of you can help me.
I recently had my AC serviced and the AC guy recommended installing a Ultraviolet Irradiation light in the Air Handler to kill any mold or other bad things that may grow on the the coils.
At first I thought he was blowing smoke and was never going to call him back. But after doing a little research on thse UV lights I notice that some think they are good and some think they are useless.
I am just trying to figure out if it's good science and I just don't know enough about the process to make this judgement. I was told it's the same process they use to irradiate food.
I know that there are a bunch of scientists here so I thought maybe someone can shed some light and tell me at minimum if this process makes sense. The UV Light gets installed in the Air Handler and the light itself kills molds and spores.
I already posted this in Heating and AC Forum but didn't feel that the responses were based on science; they were mostly anecdotal. Any help on this subject would be great!
