Indoor Air Quality

ECG has conducted dozens of investigations to determine the cause of poor air quality and odors. ECG understands the importance of responding quickly to our residential clients when indoor air quality problems arise. We are typically on site with testing equipment on the same day or the day after a call is received. In many cases, the problem is identified during the initial visit.

Two factors commonly involved with indoor air quality problems are pollution sources and the heating, ventilating and air conditioning (HVAC) system. The pollutant is a source of contamination that causes odors, various physical symptoms, and/or discomfort. The HVAC system can be a source of contamination, or, when not operating properly, it can fail to effectively control air contamination and ensure thermal comfort (temperature and humidity).

The 10 most common indoor air pollutants and parameters include:

• Asbestos.
• Carbon monoxide.
• Carbon dioxide.
• Sulfur dioxide.
• Nitrogen dioxide.
• Volatile Organic Compounds.
• Formaldehyde.
• Particulates.
• Temperature.
• Relative humidity.
