I don't know about shining a UV light onto a fixed coil, but shining a light for less than a second through air that is moving through an air handling unit has no chance to sanitize an entire house. For that purpose, it is worthless. But that is what people who sell these devices will claim. To clean mold or other contaminents on an evaporator coil, I would rather use a chemical that is designed for that purpose. Even if the UV light works, there is no way for it to reach the entire coil.
