FAQs
How do UV lights improve indoor air quality in my Cowan home?
Ultraviolet (UV-C) lamps are installed inside your HVAC system—usually near the evaporator coil or inside the return-air plenum—where they disrupt the DNA of mold spores, bacteria, and many viruses as air cycles past them. Because Cowan’s warm, humid summers promote biological growth inside ductwork, the continuous disinfection provided by UV lights prevents colonies from forming on the coil and circulating through your living space, resulting in cleaner, healthier air and fewer allergy or asthma triggers.
Will adding UV lights affect the performance of my existing heating and air-conditioning equipment?
When professionally installed, UV lamps actually help your equipment perform better. By keeping the coil and drain pan free of microbial buildup, airflow remains unobstructed and heat transfer is more efficient, which can restore lost cooling capacity and reduce strain on the blower motor. The lights themselves draw only 10–30 watts—about the same as an LED bulb—so their power consumption is minimal compared with the efficiency gains achieved from a cleaner system.
How often do UV bulbs need to be replaced and what maintenance is required?
Most HVAC-grade UV lamps are rated for 9,000 hours (roughly one year of continuous use). For reliable germicidal output, we recommend replacing the bulb every 12 months during your annual HVAC tune-up. Maintenance is simple: a technician will disconnect power, wipe dust from the quartz sleeve if present, swap in the new lamp, and verify that the safety interlock and ballast are working. No additional cleaning chemicals or filter changes are required beyond your normal filter schedule.
Are UV germicidal lights safe for my family and pets?
Yes—when installed correctly. The UV-C wavelength used (around 254 nm) is contained inside the duct or air-handler cabinet and cannot reach occupied spaces. Our Cowan technicians mount the fixtures so the light never shines through supply vents, and service panels have safety interlocks that shut the lamp off when opened. As long as you avoid staring directly at an energized bulb during maintenance, there is no risk of skin or eye damage, ozone production, or off-gassing.
Can UV lights help lower my monthly energy bills?
Indirectly, yes. Biofilm on the evaporator coil can increase static pressure and insulate the coil’s surface, forcing your compressor and blower to work harder. Studies show that a clean coil can improve overall system efficiency by 10–15 %, which translates into noticeable energy savings—especially during Cowan’s long cooling season. Because UV lamps cost only a few dollars a month to operate, the efficiency gains often offset the operating cost, delivering a positive return on investment.
Why should I choose a local Cowan HVAC professional for UV light and ventilation upgrades?
Local experts understand the specific air-quality challenges of Franklin County—high pollen counts in spring, humidity-driven mold in summer, and wood-smoke particulates in winter. Our technicians are NATE-certified, licensed, and insured to work on both residential and light-commercial systems. We evaluate your duct design, static pressure, and ventilation rate to recommend the correct UV model and placement, handle permitting, and provide manufacturer-approved warranties. Partnering with a nearby team also means faster response times and ongoing support if you ever need replacement bulbs or system diagnostics.
