FAQs
What is UV air purification and how does it work inside an HVAC system?
UV air purification uses short-wave ultraviolet (UV-C) light (around 254 nm) to disrupt the DNA and RNA of microorganisms such as mold spores, bacteria, and viruses. A technician mounts one or more UV lamps inside the air handler—typically just downstream of the evaporator coil or in the return plenum—so the circulating air and the damp coil surface are continuously exposed to germicidal light. As the HVAC blower moves air across the lamp, pathogens are deactivated before they can recirculate through your ductwork and living space.
Why is UV purification especially beneficial for homes and businesses in Farragut, TN?
Farragut’s warm, humid climate is ideal for mold growth on evaporator coils and inside ductwork. Seasonal allergens such as pollen can also accumulate in closed buildings during long cooling seasons. A properly sized UV system reduces biological growth on HVAC components, keeps coils cleaner (which maintains energy efficiency), and lowers airborne concentrations of mold, bacteria, and certain viruses—helping allergy and asthma sufferers breathe easier in our region’s high-humidity environment.
Will a UV air purifier remove all viruses, bacteria, and allergens from my indoor air?
No single technology can eliminate every contaminant. UV-C is highly effective against many microorganisms—including up to 99 % of certain bacteria and viruses given sufficient exposure time—but it does not physically trap particulate allergens such as dust or pollen. For comprehensive indoor air quality, UV lamps are typically paired with a good MERV-13 (or higher) filter, proper ventilation, and humidity control. Think of UV as one layer in a multi-layer defense strategy.
How is a UV light installed in my existing heating and air conditioning system, and will it increase my energy use?
Installation usually involves cutting a small access port in the sheet-metal plenum and mounting a low-profile lamp assembly with a sealed viewing window. Most residential UV systems plug into a 120-V outlet or are hard-wired to the air handler so they run only when the blower operates. Power draw is minimal—commonly 15–25 watts per bulb—so the annual electricity cost is roughly the same as running a small LED light and is often offset by the efficiency gains of a cleaner evaporator coil.
What maintenance does a UV purification system require, and how long do the bulbs last?
UV-C output slowly diminishes even if the bulb still lights. Manufacturers recommend replacing lamps every 9–12 months (for residential) or 8,000–9,000 operating hours to maintain germicidal effectiveness. During routine HVAC tune-ups, the technician should also wipe dust from the quartz sleeve, check wiring, and verify the safety interlock or view port. Aside from annual bulb replacement and occasional cleaning, UV systems are largely maintenance-free.
How does UV purification integrate with other ventilation and air quality solutions we offer in Farragut?
UV equipment complements, rather than replaces, other IAQ upgrades. Energy-recovery ventilators (ERVs) introduce fresh outdoor air while minimizing heat-loss; high-MERV or HEPA filters trap fine particulates; and whole-home dehumidifiers keep relative humidity below 60 %. By adding UV-C at the coil or in-duct, you target microbial threats that filtration and ventilation do not neutralize. Our Farragut technicians can design a balanced package—combining UV lights, proper filtration, controlled ventilation, and humidity management—to meet ASHRAE and EPA guidelines for healthy indoor air.
