Ultraviolet Air Treatment System

Ensure high efficiency and indoor air quality for your home's HVAC system.

Comfort Technologies

Germicidal UVC light technology


The YORK® Affinity™ Series Ultraviolet Air Treatment System actively destroys the microbial and virus growth that can occur when an HVAC system experiences condensation. Mold, fungus and harmful bacteria can affect the odor in your home, not to mention indoor air quality. The ultraviolet light in this air treatment system continuously cleans the coil and drain pan of your system, helping it run more efficiently and removing harmful pollutants. While many commercially available UVC lights are designed for optimal performance at room temperature, they are not suitable for the damp, cool, fast-moving airstream environment found in residential heating and cooling systems. The Affinity™ UVC Germicidal Light is best suited for this environment and is the ideal solution for irradiating contaminants in the shortest amount of time.



Ultraviolet light, installed in the ductwork of your system kills harmful bacteria and viruses, improving IAQ and reducing airborne irritants.


Maintenance is only required yearly, and constant operation improves your HVAC system's efficiency.


Our Certified Comfort Expert™ Contractors make sure your ultraviolet air treatment system is installed and serviced correctly from day one.


5-year parts and 1-year bulb and power assembly limited warranty ensures years of reliability.
