This makes them ideal in many scenarios for keeping the air cleaner to breathe.
UV (Ultraviolet) light is on the lower end of the light wavelength spectrum and is electromagnetic radiation.
The Sun also radiates UV light with roughly 10 percent of the Sun’s output containing Ultraviolet light.
When a person is sunburned this is from the Ultraviolet light the Sun emits.
One of the benefits of short-wave ultraviolet light is it sterilizes areas it comes into contact with.
For HVAC systems this means it can help to sterilize air as it passes a UV light.
How Hard are UV Lights to Install in an HVAC System?
The difficultly of installing UV lights depend on the location of the air handler.
The air handler often contains the evaporator A-coil from the air conditioner and is also often the supply for air into the system.
If there is a gas furnace in a home the air handler is usually located at the bottom of the furnace.
The bottom panel form the furnace should be removed to see the best spot to locate the UV light.
While usually mounted in the air handler they can also be mounted at other locations.
All the air in an HVAC system will flow through the air handler making an ideal location.
Where to Buy an HVAC UV Light?
HVAC UV lights can be bought at hardware stores, HVAC companies, and online.
If an HVAC company is hired to install the lights they will have them available.
If you plan to install them yourself buying them online such as Amazon is a good place to read reviews and get the best option.
Caution!! Do not stare directly at a UV light as like the Sun it emits electromagnetic radiation that can hurt your eyes.
