Indoor Air Quality

We investigate indoor air quality complaints including

  • temperature extremes
  • stuffy air
  • odors
  • sleepiness
  • headaches
  • nasal congestion
  • the presence of active mold growth
  • dry air

Individual sensitivities will cause each person to react differently, and often the source of symptoms people experience is something other than building conditions. If any of the above conditions persist for more than two weeks, or if 25% of the occupants suffer from the same symptoms, the issue may be related to the building.

To report an indoor air quality problem, please contact Safety and Compliance at 217-265-9828, or

Please review the Indoor Air Quality Fact Sheet if you have a concern you might need help with.
