Tell Me How UV Lights In HVAC Units Work

Posted by Daniel Lawrence on May, 2019

When people breathe dirty air through the ducts in their homes, they spend a lot of money at the doctor office. The ducts are the perfect breeding places for mold, mildew, dust, dirt, pet dander, wildlife, and other contaminants. It’s a scientific fact that indoor air quality is worse than that outdoors.

The trouble is that homeowners can’t see inside the ducts, or they would clean them. That’s where your local air conditioning company from Palatine enters the picture. They use UV lights to kill bacteria and other contaminants in the ducts. How do UV lights work?

How UV Lights Work

Air passes through the coils of the HVAC unit. Before it’s blown into the structure, the UV lights kill the bacteria and mold spores in the air along with other growths. UV lights don’t affect dirt and dust, but the other growths are history. UV lights are particularly useful in hot and humid areas which keeps the coils wet.

How To Maintain UV Lights

UV lights require maintenance along with the HVAC unit. The bulbs should be replaced every year and dusted twice per year. The bulbs are expensive and should be used only for those with allergies, asthma, and chronic pulmonary disease. Homeowners not mechanically-minded should call their local air conditioning company for maintenance, including UV lights.

Tip: Protect your eyes when working with UV lights. They will burn the retina of the eye in seconds flat.

Those whose chests have closed up from breathing mold spores know what it’s like to have dirty ducts. There’s no fright quite like being unable to breathe.
