Indoor air quality is one concern that building managers and
building inhabitants have when they decide to investigate their HVAC system.
Through normal occupation in a building, we generate a great deal of
contaminants and air pollutants, such as dander, dust, and chemicals. These
contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per
day, on average. Over time, this re-circulation causes a build-up of
contaminants in the ductwork.
While a contaminated HVAC system doesn’t necessarily mean
unhealthy air, the situation may be contributing to larger health issues or
harboring contaminants that could cause serious problems for people with
respiratory health conditions, autoimmune disorders or some environmental
allergies.
Wet portions of mechanical air systems are notorious
breeding grounds for biological contaminants. An annual inspection of a
building’s mechanical air system will reveal the severity of contaminant levels
within the system and the extent of cleaning necessary. Having a mechanical air
system reconditioned will remove allergens like dust, dander, insect remains,
microbial growth and bacteria from the system and will, in turn, provide for a
healthier environment to live or work in.
