HVAC Systems are composed of many mechanical parts, reservoirs and sometimes miles of complex ductwork, all of which collect dust and debris over time. Contaminants in ductwork can range from common nuisance dust and soil, bacteria, fungi and mold. HVAC Systems are a perfect breeding ground for biological contaminants (bacteria, fungi, viruses) due to their enclosed space, constant temperature, humidity and dirt as a nutrient source and none more than the coils associated with the system. Areas within HVAC Systems commonly trapping and containing contaminants include condensate pans/drains, areas downstream of cooling coils and areas around humidifiers.
Research has shown that cleaning even “lightly” fouled heating and cooling systems can result in energy savings greater than 10% and greatly reducing any potential biological contaminants that may find their way into any occupied space.
