Ultra Violet Lights for AC units

| These are very good for help with the quality of the air. I have one in the return and one on the indoor coil so you will not get build up of algae in your indoor coil pan causing emergency calls from system failure. Stopped up drains is not a 10 year parts and labor warranty issue or repair. It also helps from the mold build up on your coil.
The light needs to shine on the area so I would recommend one every 24′ in supply duct and one in the return and one at your indoor coil .If you can only afford one then I would recommend one on the indoor coil area or in the return only. The reason is think of yourself being in a car wash going 1 mph verses going 10 mph which is going to clean better? The one going 1 mph that is the same in a AC supply the air moves slower than in a AC return. When the air moves slower it has more cleaning affect on your air. If you have a standard pleated filter I have seen these lights in supply slow down the dust mites build up in your supply duct. But it is still best to have a Clean Affects air cleaner with UV lights. |
