FAQs
What is a UV-light upgrade for a heating and air-conditioning system and how does it work?
A UV-light upgrade adds one or more ultraviolet (usually UV-C) lamps inside the air handler or ductwork. As air passes the lamp, the short-wavelength light penetrates the cell walls of microorganisms such as mold spores, bacteria, and many viruses, disrupting their DNA so they can no longer reproduce. The result is cleaner, healthier air continuously treated every time the HVAC blower runs, without adding chemicals or fragrances.
Why is a UV-light system especially beneficial for homes and businesses in Dunlap?
Dunlap’s humid summers, pollen-heavy spring, and relatively mild but damp winters create ideal conditions for mold growth and allergen buildup in ductwork and coils. A UV-light system helps suppress that biological growth, lowers allergen counts, and reduces odors from bacteria—issues that local residents frequently report. UV treatment also complements upgraded filtration, giving an added layer of protection during seasonal allergy spikes and flu season.
Will installing a UV lamp increase my energy bill or harm HVAC components?
A typical residential UV lamp draws about the same power as a 25–40-watt light bulb, so the annual operating cost is only a few dollars. Because the lamp is mounted downstream of sensitive plastics and wiring and produces minimal heat, it does not damage coils, plenums, or insulation when installed correctly. In fact, by keeping the evaporator coil cleaner, it can improve heat-transfer efficiency and slightly reduce energy use over time.
How is a UV-light system installed in my existing equipment?
During an on-site visit, our technician identifies the best irradiation point—usually just downstream of the evaporator coil or inside the supply plenum. A small access hole is cut, the lamp assembly is mounted with a gasketed flange, and low-voltage wiring is tied into the air handler’s control board so the lamp runs only when the blower operates. The job typically takes 1–2 hours with no disruption to ductwork and no loss of conditioned air.
What maintenance does a UV-light need and how often are bulbs replaced?
The quartz bulb gradually loses intensity after about 9,000 operating hours—roughly one year of typical blower run time in Dunlap. We recommend annual bulb replacement during your spring or fall tune-up. Aside from that, maintenance is limited to wiping dust from the lamp housing and confirming the safety interlock shuts the lamp off when the access panel is removed. Most homeowners bundle this with their regular HVAC service plan.
How much does a UV-light upgrade cost in the Dunlap area, and are rebates available?
A single-lamp residential system ranges from $350 to $600 installed, depending on lamp output and whether your unit needs an external power supply. Multi-lamp commercial configurations start around $800. TVA EnergyRight and some local utilities periodically offer $25–$75 incentives for qualified indoor-air-quality upgrades; our office can help you check current programs and file the paperwork. Because UV keeps coils cleaner, many customers recover part of the cost through lower maintenance and improved efficiency over the first few years.
