This video will show how a standard make-up air ventilation system works and the benefits of preventive maintenance on this
critical system in your building. You will see a professional tradesperson carry out a typical preventative maintenance call,
as well as some simple tasks that your staff can perform to keep your make up air unit running properly.

Let our HVAC inspectors conduct a comprehensive examinations of components and systems to determine whether they are
contaminated with a significant accumulation of particulate or microbial growth, or if HVAC performance is compromised
due to contamination build-up.

PREVENTION of duct contamination is KEY to avoiding problems.
Follow these recommendations to avoid system contamination:

•Perform routine preventive maintenance on HVAC
systems, by complying with manufacturer schedules
for changing HVAC filters, cleaning coils, and other

•During building renovation, seal ductwork to prevent
construction dust and debris from entering the HVAC

•Maintain good housekeeping in occupied spaces.

•Ensure that air intakes are located away from
contaminant sources.

•Consider routine inspections of ductwork. The National
Air Duct Cleaning Association (NADCA)’s standard,
“Assessment, Cleaning and Restoration of HVAC Systems-
ACR 2013,” recommends that HVAC systems be visually
inspected for cleanliness at regular intervals, depending
on building use. For healthcare facilities, the standard
recommends annual inspections of air handling units
and supply/return ductwork
