Duct & drain cleaning

The profession of cleaning HVAC (Heating, Ventilation and Air Conditioning) systems is defined as the safe removal of unwanted substances and foreign materials for the purpose of eliminating conditions that are potentially harmful to health, well-being or productivity of building occupants, or that impede the performance of the HVAC system. With increased public awareness of indoor air quality (IAQ) issues, the IAQ field has seen a corresponding demand for HVAC system cleaning services. As a result of this demand and the growth of the HVAC cleaning industry, the need for a credentialing system to recognize competent, qualified HVAC system cleaning specialists has arisen. The National Air Duct Cleaners Association (NADCA) is recognized as the premiere standard-setting organization today in the field of HVAC system cleaning. In keeping with this tradition, NADCA has developed a certification program. The NADCA Certification Examination is a principal component of the overall program and sets
a new standard among HVAC system cleaning professionals.
