HVACs and Indoor Air Quality

According to the U.S. Environmental Agency, we spend 90% or more of each day inside of our home, school, workplace, or car. According to the Environmental Protection Agency (EPA), the air inside the average home is up to five times more polluted than the air outside. Results from in-home air tests across North America support this government finding. Nearly every home (96%) had at least one indoor air quality problem.

The Center for Disease Control (CDC) reports that Indoor air quality problems can be produced when contaminants enter a building with the outdoor air. Rooftop or wall-mounted air intakes are sometimes located adjacent to or downwind of building exhaust outlets or other contaminant sources. Problems can also result if debris (e.g., bird droppings) accumulates at the intake, obstructing airflow and potentially introducing microbiological contaminants. If more air is exhausted than is introduced through the outdoor air intake, then outdoor air will enter the building at any leakage sites in the shell. Indoor air quality problems can occur if the leakage site is a door to a loading dock, parking garage, or some other area associated with pollutants.

Leakage of air from ducts can cause or exacerbate air quality problems, in addition to wasting energy. In general, sealed duct systems specified with a leakage rate of less than 3% will have a superior life cycle cost analysis and reduce the likelihood of problems associated with leaky ductwork, according to the CDC.
