Germicidal or UV lights can be added to your home’s heating and cooling system – but do they work? The fact is, ultraviolet devices offer several benefits when added to your home’s HVAC system.
However, what are UV lights, and how do they improve your home’s indoor air quality and benefit your family’s health? Here are a few reasons to consider adding UV lighting to your HVAC system.
I’ve been using “THOMAS Hoffmann Airconditioning and Heating LLC” for years now. We have a 30 +\- year old system that works perfectly for us. Although we’ve not had to use it yet, it is comforting to know they offer a 24 hour on call service. I really appreciate that the technicians don’t try to upsell us on anything. They’re a very professional, knowledgeable, and courteous, local-family owned and operated business. I’ve also found their pricing to be very fair and by”fair” I don’t mean “cheap” but reasonable… especially for the quality of service provided by THOMAS Hoffmann HVAC. I love supporting smaller family owned business and this one is top-notch! Thank you guys!

0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.
Response from the owner:Hi there. I am unable to locate your customer profile. Please give our office a call at 314-471-7625 so we can get this figured out for you.

What are UV Lights for HVAC Systems?
Ultraviolet radiation is a type of energy produced by the sun. But UV lighting used in technology as a sterilizing agent has been around for a little more than 100 years. Is it currently embraced as an effective way disinfect air in homes and businesses.
In the beginning, scientists initially proved that UV light contained bacteria-killing properties. This tremendous discovery allowed UV air purifiers to reduce the spread of diseases and improve indoor air quality. Modern-day UV air filtration has improved exponentially and can benefit homes, schools, commercial buildings, and more.
How Does UV Improve Indoor Air Quality?

Lamp position
Lamp wavelength and intensity
Duct reflectivity
