FAQs
How do UV air purifiers work and what contaminants do they remove?
A UV air purifier uses UV-C light (a short-wave ultraviolet wavelength) to break down the DNA or RNA of microorganisms that pass through your HVAC system. When installed in your air handler or ductwork, the lamp continuously bathes the circulating air, neutralizing up to 99% of airborne bacteria, viruses, mold spores, and some volatile organic compounds. While it is not a particulate filter, it complements your existing HVAC filter by inactivating biological contaminants that would otherwise survive and recirculate throughout your Charleston home.
Are UV air purifiers safe for my family and pets?
Yes. The UV-C lamp is mounted inside sealed HVAC components where no direct light escapes into living spaces, so skin and eyes are never exposed. The wavelength used is below the ozone-producing range, so it will not create harmful ozone. Because the purifier targets microorganisms in the airstream without adding chemicals or scents, it is one of the safest air-sanitizing options available for households with children, elderly residents, or pets.
How is a UV air purifier installed in my existing HVAC system?
A licensed HVAC technician cuts a small access hole in the supply plenum or positions the lamp near the evaporator coil—prime breeding grounds for mold and bacteria. The unit is then wired to the air handler’s power supply so it operates whenever the system runs (or continuously, if preferred). Installation typically takes one to two hours, requires no major duct modifications, and can be completed during a routine maintenance visit. Our Charleston crew ensures proper lamp placement for maximum exposure time and minimal airflow restriction.
How often do the UV lamps need to be replaced and what maintenance is required?
Most UV-C lamps are rated for about 9,000 operating hours—roughly one year of continuous use or two years of HVAC-cycle-only operation. We recommend annual lamp replacement to guarantee full germicidal strength and to include it in your spring or fall HVAC tune-up. Beyond lamp changes, maintenance involves wiping the quartz sleeve to remove dust buildup and confirming the ballast and safety shutoff are functioning properly. The entire process is quick and inexpensive compared with overall HVAC upkeep.
Will a UV air purification system increase my energy bills?
The average UV lamp draws 15–40 watts—comparable to an LED light bulb—adding only a few dollars per month to your electric bill. In many cases, the purifier saves energy indirectly by keeping the evaporator coil free of biofilm, which can otherwise insulate the coil and reduce heat-transfer efficiency. A clean coil allows your air conditioner to cool faster and run shorter cycles, an important advantage in Charleston’s long, humid cooling season.
Why is indoor air quality especially important in Charleston’s climate?
Charleston’s mix of high humidity, coastal allergens, and year-round pollen can trap moisture and biological contaminants inside tightly sealed modern homes. Mold, mildew, and dust mites thrive in our warm, damp environment, aggravating allergies and asthma. A comprehensive indoor air quality strategy—combining UV purification, proper ventilation, high-efficiency filtration, and humidity control—helps protect your family and preserves your HVAC equipment from microbial buildup that flourishes in Charleston’s subtropical climate.
