FAQs
What are UV germicidal lights and how do they work in my HVAC system?
UV germicidal lights use short-wave ultraviolet (UV-C) energy to break down the DNA and RNA of microorganisms such as mold spores, bacteria, and viruses. When installed in your heating and air conditioning equipment, the lamps continuously bathe the interior surfaces or passing air stream in UV-C light. As air cycles through the system, pathogens are exposed to the UV rays and are rendered unable to reproduce, greatly reducing their concentration before the air is delivered back into your living spaces.
Why are UV lights an effective solution for indoor air quality issues specific to Decherd?
The Decherd area experiences long warm seasons and higher humidity levels that encourage mold and bacterial growth on evaporator coils and inside ductwork. In addition, our rural surroundings contribute pollen and agricultural allergens to the air. UV-C lamps target mold and bio-film on HVAC coils, preventing them from becoming a breeding ground for pathogens, and they inactivate airborne microorganisms that make it past the standard filter. The result is cleaner, fresher air with fewer allergens and odors—something many Decherd homeowners appreciate during both allergy season and the humid summer months.
Where are UV germicidal lights installed within a heating and air conditioning system?
Most residential systems use one of two mounting methods: (1) Coil-irradiation, where a UV lamp is mounted just downstream of the evaporator coil. This placement keeps the damp coil surface free of microbial growth. (2) In-duct or ‘air-stream’ installation, where the lamps are positioned inside the supply or return plenum so the moving air is exposed to UV-C light. A qualified HVAC technician will evaluate your equipment layout, airflow rate, and service accessibility to choose the location that delivers maximum pathogen kill while allowing easy bulb replacement.
Are UV germicidal lamps safe for my family, pets, and HVAC components?
Yes—when properly installed, the lamps are mounted inside sealed equipment or ductwork, so occupants and pets are never exposed to direct UV-C radiation. The fixtures have metal housings and safety interlock switches to prevent accidental exposure during servicing. UV-C light used in HVAC systems does not produce significant ozone, and it does not degrade metal ductwork or typical coil materials. As with any electrical device, only trained professionals should install or service the lamps to ensure safe operation.
How much maintenance do UV lamps require and how often should the bulbs be replaced?
Unlike air filters, UV lamps don’t get clogged, but they do lose intensity with time. Most bulbs maintain germicidal output for about 9–12 months of continuous operation. Your HVAC technician will check lamp intensity during annual maintenance visits and recommend replacement when output falls below effective levels. Aside from bulb replacement, upkeep involves cleaning any dust from the lamp housing and confirming the ballast and safety switch are functioning. The process is quick and typically coordinated with your routine HVAC tune-up.
Will adding UV lights increase my energy bills or affect HVAC efficiency?
A typical residential UV-C lamp draws only 15–40 watts—about the same as an LED lightbulb—so the direct electricity cost is minimal. In fact, by preventing organic buildup on your evaporator coil, the lights can help the coil transfer heat more efficiently, potentially reducing compressor run time and trimming overall energy use by up to 10–15 %. Cleaner coils also extend equipment life and reduce the need for chemical coil cleanings, providing additional long-term savings.
