Is my duct work dirty? Should I have it checked?

2/19/2021 (Permalink)

The ventilation system within your commercial space is key to your air quality.

Estimates made by the World Health Organization say that poor indoor air quality cost $60 Billion in employee sick leave and lost production.

Poor air quality can spread illness, cause respiratory irritation, and cause employees to feel drowsy or apathetic. In some cases, it can spread illness and cause employees to become sick frequently.

You don’t want to keep the air in your commercial space too dry nor too humid. Both ends of the humidity spectrum cause health effects and can make your staff uncomfortable. Instead, try to keep the humidity level in your building between 40 and 50 percent.

The ventilation system is often the biggest culprit in poor indoor air quality. Inspecting the ductwork must be a high priority. 

In most cases, the HVAC system has been operating for some time without much attention. Dirty ducts can circulate odors, contaminants such as mold and irritating dust throughout your office building.

Another problem that affects ductwork in commercial businesses is when input and output vents become blocked by boxes, equipment, furniture or dust. This reduces the free flow of air through ducting systems and, by association, reduces air circulation throughout the entire commercial building.

Part of your responsibility to the tenants, workers, and/or students who work and play in your buildings includes proper maintenance and prompt response to any situation that could cause illness or health effects.
