FAQs
How do UV purification lights improve indoor air quality in my Etowah home?
UV (ultraviolet) purification lights emit a specific wavelength (typically 254 nm) that penetrates the cell walls of microorganisms such as mold spores, bacteria, and viruses, disrupting their DNA so they cannot reproduce. When installed inside your heating and air-conditioning system, the lights continuously disinfect the air that circulates through the ductwork. This helps lower overall microbial counts, reduces musty odors, and supports healthier indoor air—especially valuable in Etowah, where high humidity can foster mold growth.
Where are UV lights installed within an HVAC system, and will they affect heating or cooling performance?
There are two common installation locations: (1) in the supply plenum or return duct to sterilize moving air; and (2) near the evaporator coil to keep the coil and condensate pan free of biofilm. The lamps operate silently and draw very little power (usually 15–30 W per bulb), so they do not reduce heating or cooling capacity. In fact, a cleaner coil can improve system efficiency because airflow remains unobstructed.
Are UV purification systems effective against viruses, bacteria, and mold common in East Tennessee’s humid climate?
Yes. Independent laboratory tests show that properly sized and installed UV-C systems can inactivate up to 99 % of airborne pathogens in a single pass. Because Etowah’s climate is warm and humid for much of the year, mold spores thrive in ducts and on coils; UV light disrupts those spores before they circulate. The technology has also proved effective against common cold and flu viruses and even SARS-CoV-2 when exposure time and intensity are sufficient.
What maintenance do UV lights require, and how often should bulbs be replaced?
The lamps gradually lose intensity, so the quartz bulbs need replacement about once every 9,000 hours—roughly once a year if they run 24/7. Maintenance involves: (1) safely switching off power, (2) removing and disposing of the old bulb like any fluorescent lamp, (3) wiping the new bulb with alcohol to remove fingerprints, and (4) reinstalling it. During your routine HVAC service visit, our technicians can inspect the housing, check electrical connections, and replace bulbs as needed.
Will installing a UV purification light system increase my energy bills?
The energy draw is minimal; a typical residential bulb consumes about the same power as a night-light, adding only $1–$2 per month to most Etowah electric bills. Any extra cost is often offset by efficiency gains from a cleaner evaporator coil, reduced need for chemical coil cleanings, and fewer HVAC service calls related to biological buildup.
Is professional installation necessary, and do you offer financing or rebates for Etowah residents?
Professional installation is strongly recommended to ensure the UV-C lamps are sized correctly, located for maximum exposure time, and wired into the air handler’s safety switch. Our EPA-certified technicians also know how to protect sensitive plastics and seal openings to prevent stray UV light. We offer affordable financing plans and can help you apply for any Tennessee Valley Authority (TVA) or local utility rebates that promote indoor air quality improvements.
