UV Purification
UV Purification | Ventilation and Air Quality | Heating and Air Conditioning | Powell
At HEP, we believe every breath you take in Powell should feel crisp, clean, and confidently germ-free. Our team seamlessly installs UV air purification right inside your heating and cooling system, flooding the air stream with germicidal light that neutralizes bacteria, mold, and viruses before they ever reach your living spaces. Pair that technology with precision-balanced ductwork, smart thermostats, and meticulous system tune-ups, and you’ll notice quieter comfort, lower energy bills, and far fewer airborne irritants swirling around your home.
Because true indoor wellness is about more than just temperature, we design whole-home strategies that elevate ventilation and air quality day and night. From fresh-air intakes that whisk away stale indoor pollutants to high-efficiency filters that trap dust and pollen at the door, HEP gives you control over what you breathe—no matter the season. Ready to transform your house into a sanctuary of pure, revitalizing air? Give the local experts a call and feel the difference with every inhale.
FAQs
How does UV air purification work in an HVAC system, and is it really effective against viruses and bacteria?
A germicidal UV-C lamp (usually 254 nm wavelength) is installed inside your air handler or supply plenum. As air passes the lamp, high-energy UV photons penetrate the cell walls of microorganisms, disrupting their DNA so they can’t reproduce. Laboratory tests show up to 99 percent inactivation rates for common bacteria, viruses, and mold spores. Because the UV light treats the air every time it cycles through the system, it provides continuous microbial control throughout your Powell home without chemicals or ozone.
Will adding a UV light increase my energy bills or strain my HVAC equipment?
No. A typical residential UV lamp draws about the same wattage as a 40–60 W light bulb. That adds only a few dollars a month to most Powell electric bills. The lamp is installed downstream of the evaporator coil, so it doesn’t restrict airflow or reduce system efficiency. In fact, by keeping coils cleaner and preventing bio-film build-up, UV can help your system maintain its SEER rating and may slightly lower operating costs over time.
Is UV purification safe for my family, pets, and household materials?
Yes, when professionally installed inside sealed HVAC equipment, the UV-C light is completely contained and never shines into living spaces. UV-C cannot pass through metal ducts, so people, pets, plants, and furnishings are not exposed. The lamps do not generate ozone, and there are no chemical by-products. Always disconnect power before opening the air handler so you are not exposed directly to the light during maintenance.
How often do the UV bulbs need to be replaced, and can I change them myself?
Most UV-C lamps are rated for 9,000 operating hours, or about one year of continuous use. We recommend replacing them annually during your spring or fall HVAC tune-up. While handy homeowners can do the swap, the bulb is fragile and must be handled with gloves to avoid skin oils that reduce output. Our Powell technicians can change the lamp, inspect the ballast, and verify proper irradiance in one short service visit.
Can a UV purifier remove odors, allergens, or dust from my indoor air?
UV light neutralizes living contaminants (mold, bacteria, viruses) that cause many odors and allergic reactions, but it does not capture particulate matter. For best results, we pair UV purification with a high-MERV pleated filter or an electronic air cleaner. This combination kills microbes and physically removes dust, pollen, and pet dander common in Powell ’s spring and fall allergy seasons, giving you cleaner, fresher air throughout the year.
Why is UV purification especially beneficial for homes in Powell, and what other IAQ upgrades should I consider?
Powell’s humid summers encourage mold growth on evaporator coils, while tightly sealed homes trap winter germs and allergens. A UV system keeps the coil sterile and reduces circulating pathogens year-round. For a complete indoor air quality solution, consider adding a whole-home dehumidifier, a fresh-air ventilator with energy recovery (ERV), and a programmable thermostat with IAQ monitoring. Together, these upgrades balance humidity, bring in controlled outdoor air, and ensure your UV purifier works at peak effectiveness.
