Damp, humid conditions present in condenser coils, air filters, ductwork, and drain pans tend to attract microbial growth, which, left uncontrolled, can impede airflow and emit contaminants and odors into the conditioned space. One effective way of controlling microbial growth in air handlers to improve indoor air quality, reduce maintenance costs, and increase system efficiency is through UV-C, or ultraviolet light.
There are two basic types of UV-C systems, coil and in-duct, which can be used alone or in tandem for increased benefit. Coil UV-C systems are generally more effective due to continual exposure and can restore as much as 40% of system capacity according to some studies. ASHRAE recognizes the value of UV-C and has published recommendations for effective treatment. Installation is inexpensive, and a UV-C system can pay for itself in as little as six months.
