The Importance of Indoor Air Quality
According to the United States Environmental Protection Agency, most Americans spend about 90% of their time indoors. What many people don’t realize is that the air in their homes or offices could contain several times more pollution than the air outside.
Contamination can take many forms, including:
- Dust
- Mold spores
- Pet dander
- Pollen
- Volatile organic compounds
- Carbon monoxide
Some of the above contaminants are relatively innocuous. Others, such as carbon monoxide, are incredibly dangerous and must be prevented. Regular air quality testing and the correct approach to air quality remediation can help maintain a safe and healthy environment for a building’s occupants.
Indoor air quality assessment tools help HVAC technicians detect and identify contaminants, so the technician can determine what sort of remediation is required. Air quality testing tools can include:
- Carbon dioxide sensors to identify issues with poor ventilation
- Carbon monoxide detectors to test for the presence of this colorless, odorless, but deadly gas
- Particulate Matter sensors to assess the efficiency of filters and the cleanliness of HVAC ducts
- Volatile Organic Compound (VOC) sensors to detect chemicals from paints, cleaning agents, etc.
- Airflow testers to measure ventilation rates and ensure they comply with ASHRAE standards
- Pressure sensors to detect leaks, clogged filters, and other ventilation issues
Improving Indoor Air Quality
A good HVAC training course will cover not only how to test for contamination in a property, but also how to improve the indoor air quality by improving ventilation to stop carbon monoxide production, install air filters to remove dust and pollen, and using UV lights to kill microorganisms.

“Sent my son to a 4 year college right after high school, he dropped out with lack of interest, bounced around meaningless jobs as a lost soul for a couple of years until we found ETI. He graduated from the ETI HVAC program in 2019 and has been gainfully employed since. My son now has a career making a good living and not just another job. He loves it and we are so proud of his achievements. These kids are going off to college, getting into debt up to their necks with a degree that they can’t do anything with. The trades is the way to go. ETI was a lifeline for our family, highly recommended.”
