HVAC Systems are excellent breeding grounds for harmful airborne contaminants to gather and then spread throughout a building. When HVAC Systems are contaminated with dust, mold, construction debris, bacteria, or insulation fibers the indoor air quality of the facility suffers, putting patients at a higher risk in healthcare facilities, and damaging employee productivity for businesses. When the contaminants are combined with varying temperatures, humidity levels, and airflow in the HVAC System the indoor air environment can dramatically suffer. Not only are there additional health risk with a dirty HVAC System, but a system's operating and efficacy standards are impaired, resulting in higher operating cost for the facility.
