NADCA members are accustomed to handling a variety of projects for commercial and industrial buildings. NADCA’s presence in the commercial HVAC industry is growing steadily as education about our members’ services grows. It is becoming increasingly common for project proposals to specify the presence of an ASCS certified individual on a commercial job.
When hiring a NADCA member, an optimal level of performance should be expected. Technicians are required to adhere to the industry’s standards and guidelines, and inform the client of any obstacles that may prevent doing so. NADCA members are able to able to answer most questions about a particular project, including safety issues and are able to provide proof that the job has been done correctly.
Through clear, concise communications, air duct cleaning contractors can provide their clients with a better understanding of the work to be undertaken and demonstrate that the project will be well managed. Clients should also clearly define the scope of work they desire and are encouraged to utilize NADCA’s General Specifications for the Cleaning and Restoration of Commercial Heating, Ventilating and Air Conditioning Systems.
HVAC system cleaning projects require a game plan. Project length can vary from a few hours to six months or more. The size and scope of the project are the two key elements that will have an impact on the length of time necessary for completion. The entire duct cleaning project will run smoothest when an in-depth review is first conducted to determine the expectations and desired outcome for both the customer and duct cleaning company.
- During cleaning, the entire HVAC system is placed under continuous negative pressure — with a vacuum — to prevent the spread of contaminants.
- Continuous negative pressure allows very fine particles to be removed from the system as they become airborne, ensuring that these particles are not released into the living space when the system is turned on after cleaning.
- This negative pressure also serves to extract the loosened contaminants, which are collected and removed from your home.
Often, HVAC system components collect significant amounts of debris and particulate during construction activities within a building. NADCA recommends that newly installed HVAC systems or HVAC systems undergoing renovation be verified clean and protected before the system is permitted to operate.
