UV Lights: Keeping Indoor Pollutants in Check Before It Leaves the Ductwork

There are plenty of smart, innovative ideas that all of us at Scott’s Heating & Air Conditioning are eager to pass along, and this one has got to rank among the top five: installing UV lights in your ductwork to catch pollutants before they infiltrate the air that you breathe—the air you depend on for your health and well-being.

Allow me to paint the picture: the air in your HVAC system races through your ductwork as often as 75 times per day during the heating and cooling season and up to 150 times per day if your system is on “fan” mode.

Each and every time, everything within your ductwork races along with that warm or cool air. So any dust, bacteria, mold and viruses that reside in your ducts come along for the ride too. (This isn’t to say that your ducts are chock-full of these contaminants. But every active household accumulates its fair share of irritants; it’s inevitable.)

Ultraviolet lights installed in your ductwork can kill these contaminants on contact—not just weaken them, but strike them a fatal blow. UV lights alter the genetic structure of germs. For this very reason, UV lights are commonplace in hospitals, pharmacies and commercial kitchens where it’s vital to keep harmful pollutants at bay.

Ultraviolet lights are pretty close to perfect. They’re known to boast a 99.9 percent effectiveness rate, which means they will do their fair share at ensuring that the air that flows from your ductwork will be as clean and healthy as it can be.

The science of it all is deceptively simple: ultraviolet lights can be easily added to a central heating or air system, on the supply side or in the return air ductwork. We can have one installed in your system in just about a half hour.  Further, this home improvement project is incredibly low-maintenance. UV lights are effective for as long as two years. And after that, replacement bulbs are economical.

If you’re catching our enthusiasm for installing UV lights in your ductwork, call Scott’s Heating & Air Conditioning for more information about this sensible and positively (we can’t help but say it) illuminating idea.
