What Our Customers Have to Say
Frequently Asked Questions
What are UV lamps and how do they work?
Ultraviolet (UV) lamps are also called UV bulbs or germicidal lamps. A UV system can be added to your existing heating/cooling system near your AC evaporator coil or directly in the airstream. UV light is germicidal, which means it deactivates the DNA of microorganisms like bacteria, viruses, and other pathogens, short-circuiting their ability to multiply and cause disease and unwanted odors.
How often should I change my UV bulb?
Annual UV bulb replacement is recommended annually. Over time - the output intensity of UV germicidal lamps will decrease. So - even if an old bulb is lighting up/turning on, it may not be nearly as effective as it once was.
What’s the difference between UV and UVC?
"UV" is a general term for ultraviolet. The "C" in "UVC" describes the specific UV wavelength that has been found to have germicidal properties. UVC or UV-C light is traditionally referred to as "germicidal UV" because of it’s proven ability to kill bacteria, mold, and fungi.
Is UV light bulb replacement easy?
Yes. Consult the owner’s manual for information on replacement. Usually, UVC bulb replacement is a simple matter of turning off power to your HVAC system, removing a few screws, and inserting a new bulb. There is no reason this can’t be a DIY project.
