UV Light Purification
UV Light Purification | Ventilation and Air Quality | Heating and Air Conditioning | Greeneville
When Greeneville’s humidity rises or a winter chill settles in, HEP’s UV light purification systems go to work inside your HVAC equipment, bathing every cubic foot of air in germ-destroying ultraviolet energy. The result is a fresher, healthier home where mold spores, bacteria, and lingering odors are neutralized before they ever reach your living spaces. Pair that with our meticulous duct sealing and balanced airflow solutions, and you’ll feel the difference in comfort the moment you step through the door.
Local, licensed technicians install and maintain these systems alongside high-efficiency furnaces, heat pumps, and AC units, ensuring the perfect blend of temperature control and ventilation and air quality. From free in-home assessments to around-the-clock emergency service, HEP gives Greeneville homeowners one trusted team for cleaner air, lower energy bills, and year-round peace of mind.
FAQs
How does UV light purification work inside my HVAC system?
A specially designed UV-C lamp is installed in the air-handler or in the supply plenum of your heating and air conditioning system. As the air cycles through the HVAC equipment, the UV-C wavelength (254 nm) penetrates the DNA of mold spores, bacteria, and many viruses, rendering them unable to reproduce. Because the light is positioned where the coil and drain pan stay damp, it also keeps those components free of bio-growth, which improves overall system hygiene and boosts airflow efficiency.
Will UV lights remove odors, allergens, and dust from my Greeneville home?
UV purification primarily targets living microorganisms such as mold, bacteria, and viruses. By destroying these contaminants, it can reduce musty smells and allergy triggers that result from bio-growth. However, UV lamps do not capture dust, pet dander, or smoke particles; you still need a high-quality filter or an electronic air cleaner for particulate removal. Pairing UV lights with a MERV-13 (or higher) filter offers a comprehensive solution for Greeneville’s pollen-rich spring and fall seasons.
Are UV light systems safe for my family and pets?
Yes—when installed correctly inside the sealed HVAC cabinet, the UV-C rays never leave the ductwork, so people and pets are not exposed. All service panels are fitted with safety interlocks or warning labels, and our technicians wear protective gear during maintenance. The bulbs produce no ozone and meet UL 2998 zero-ozone standards, so indoor air quality is improved without introducing harmful by-products.
How often do UV bulbs need to be replaced in Greeneville’s climate?
Most residential UV lamps are rated for 9,000–10,000 operating hours, or about one year of continuous use. Because East Tennessee’s humidity encourages faster bio-growth, we recommend annual bulb replacement to maintain peak germicidal output. During your spring or fall HVAC tune-up, our technician will swap the lamp, clean the mounting hardware, and verify that the ballast is operating at the proper voltage.
Can installing UV lights lower my energy bills?
Indirectly, yes. By keeping the evaporator coil free of bio-film, UV lights allow heat to transfer more efficiently, which can restore lost capacity and reduce compressor run-time by up to 10 %. A cleaner coil also improves airflow, helping your system reach set temperatures faster. While savings vary by household, many Greeneville homeowners notice shorter cooling cycles and fewer service calls, offsetting the modest annual bulb-replacement cost.
What is the installation process and cost for a UV purification system in Greeneville?
A typical install takes about 1–2 hours. Our technician inspects your air-handler to choose the optimal lamp location, drills a small access hole, mounts the UV fixture, and wires it to the HVAC control board or a dedicated 120-V outlet. We then seal the access point and test the system. For most homes, a single-lamp system ranges from $350–$550 installed, while a dual-lamp coil and air-stream package averages $650–$850. We provide flat-rate quotes up front and offer financing options for qualifying customers.
