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.
