UV-C Highly Effective in Residential and Commercial HVAC
UV-C, or ultraviolet light as a method of eliminating microbial growth in HVAC systems and improving indoor air quality has long been underutilized in residential and light commercial sectors, despite the fact that it has been widely touted by industry experts. Fortunately for home and business owners, HVAC contractors are finally catching on to one of most effective ways to improve IAQ, airflow, and heat transfer.
UV-C has been used as a germicide for many years in such applications as equipment sterilization and water purification. By targeting DNA, it causes microbe death or renders them unable to reproduce. In HVAC systems, damp, humid conditions encourage growth of mold, biofilm and other organic compounds on coils, filters, duct surfaces, and drain pans. Eventually, this accumulation chokes airflow, decreases system efficiency, and releases odors and contaminants into the air. ASHRAE has found that application of UV-C light kills or inactivates 90% or more microorganisms living on HVAC system surfaces. Thus far, no microorganism has been found to be completely immune to UV-C.
Properly-maintained UV-C lamps installed in new systems will prevent microbial growth from the get-go, but existing systems can be effectively retrofit, as well. Studies have shown that UV-C can restore an air handler with microbial growth to as-built operating conditions in as little as 90 days, restoring system capacity by up to 40% and drastically reducing energy consumption.
