UV Lights | Ventilation and Air Quality | Heating and Air Conditioning | Evensville
Between tornado warnings and high pollen counts, Evensville homeowners spend a lot of time sealed indoors. Yet the air behind your closed windows can be up to five times more polluted than what swirls outside. That’s why HEP’s uv lights heating and air conditioning team focuses on one thing first: ventilation and air quality.
Our certified technicians install hospital-grade UV-C lamps inside your ductwork, neutralizing up to 99 % of airborne viruses, mold spores, and bacteria before they ever reach your living spaces. Paired with precision-balanced ventilation, HEPA filtration, and smart humidity controls, these systems quietly scrub every cubic foot of air while your furnace or A/C runs—no extra noise, no harsh chemicals, just fresh, breathable comfort all year long in Evensville.

FAQs
What do HVAC UV lights actually do, and how do they improve indoor air quality in Evensville homes?
Ultraviolet (UV-C) lamps are installed inside your heating and air-conditioning system—usually near the evaporator coil or inside the supply plenum—where they emit short-wave UV light. This light breaks down the DNA and RNA of microorganisms such as mold spores, bacteria, and viruses, preventing them from reproducing. Because Evensville’s humid climate can lead to biological growth on coils and in ductwork, UV lights keep those areas cleaner, reduce musty odors, and lessen the amount of airborne contaminants that circulate throughout your living space.
Are UV air-purification systems really effective against viruses, bacteria, and mold common in our region?
Yes. Independent laboratory tests show properly sized UV-C lamps can inactivate up to 99% of common pathogens when microbes pass within the light’s irradiation zone or attempt to grow on the coil surface. Local HVAC contractors size the lamp’s output (measured in microwatts per square centimeter) to match your equipment’s airflow rate. While no single technology is 100 % effective on its own, UV lights used in conjunction with high-MERV or HEPA filtration deliver a significant reduction of biological contaminants, which is especially helpful during Evensville’s allergy and cold-and-flu seasons.
Will installing UV lights raise my energy bill or hurt my HVAC system’s efficiency?
A typical residential UV lamp draws about the same power as a 40-60 W light bulb—only a few dollars per month on the average Evensville electric bill. By keeping the evaporator coil and drain pan free of bio-film, the lamps actually help maintain system efficiency: a clean coil transfers heat more effectively, reducing compressor run-time and lowering utility costs. Most homeowners notice either a negligible change or a small net savings on energy after installation.
How often do UV bulbs need to be replaced, and what maintenance is involved?
UV-C output declines gradually over time even though the lamp may still appear to be glowing. For reliable germicidal performance, bulbs should be replaced every 12–24 months, depending on the model. Your service technician can change the bulb during your spring or fall HVAC tune-up. Other than an occasional wipe-down of dust on the exterior housing, UV systems are virtually maintenance-free. Always shut off power before servicing to avoid eye and skin exposure.
Can UV lights be retrofitted to my existing furnace or air-handler, and how long does installation take?
In almost all cases, yes. UV kits are designed to fit standard metal or fiberglass plenums and are available in various lengths to match coil size. A certified Evensville HVAC technician will drill a small access hole, mount the lamp, wire it to the unit’s 24-V or 120-V power supply, and confirm there is no light leakage into occupied spaces. The entire process typically takes 1–2 hours and does not require duct replacement or major downtime.
What does a UV air-purification system cost in Evensville, and are rebates or financing options available?
Residential UV kits range from $300–$600 installed, depending on lamp output, number of bulbs, and whether an electronic monitor is included. Replacement bulbs cost $60–$120. TVA energy-efficiency programs and certain local utilities periodically offer rebates for indoor air-quality upgrades, and many Evensville HVAC contractors provide 0 % short-term financing. During routine maintenance visits, bundling a UV install with coil cleaning or a new filtration upgrade can further reduce overall cost.
