Indoor Air Quality Testing
Testing for occupied spaces where air quality or ventilation-related conditions are a concern.
Indoor air concerns are usually described in general terms — an odor, a change in a room, or a question about how a space is ventilated. Testing turns that description into data about the conditions measured.
Results describe the conditions measured at a specific place and time, and provide information about the area that was tested.
Excel performs indoor air quality testing. Ventilation work, repairs, and other corrective measures are handled by others.

- An occupied space has developed an air-related concern.
- A question has been raised about how a space is ventilated.
- A specific occupied area has an air-quality or ventilation-related concern.
