This makes them ideal in many scenarios for keeping the air cleaner and safer to breathe.
What Are HVAC UV Lights?
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 depends on the location of the air handler.
The air handler often contains the evaporator A-coil from the air conditioner and is also usually 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 from the furnace should be removed to see the best spot to locate the UV light.
Best Location to Install HVAC 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 light, they will have them available.
If you plan to install one yourself, buying it online such as Amazon, is a good place to read reviews and get the best option.

Do not stare directly at a UV light as, like the Sun, it emits electromagnetic radiation that can hurt your eyes.
How To Install UV Light In an HVAC System
- Locate the best spot to install the UV light, usually in the air handler box.
- Drill a hole through for the UV light.
- Insert the UV light and attach it with screws.
- Plug it in and test it.
Installing a UV light is beneficial for many reasons, mainly to kill off mold, mildew, and airborne viruses.
Before buying a UV light, be sure to examine your HVAC system for the best location to install it.
Many systems can install a UV light in the air handler at the bottom of the furnace.
If your home doesn’t use a furnace and has a heat pump, the air handler will be in the packaged unit.
Package units have the return air on one side and the supply on the other side circulating the air in a home.
Often UV lights are located on the return side of a packaged system, but they can also be located on the supply side.
