North Town Specializes In Indoor Air Quality

One of the biggest concerns for any HVAC project is ensuring indoor air quality. As the most trusted Chicago HVAC specialist, North Town has decades of experience designing, repairing, and retrofitting HVAC systems to improve the air quality within and around buildings and structures, to promote the health and comfort of building residents, employees, and other occupants. Determining the quality of the air in a given facility involves many complex methods including computer modeling of air flow inside buildings, the monitoring of human exposure to pollutants, and the collection of air samples and samples from building surfaces.

The process is so complex because many factors affect indoor air quality. Lack of outside air (ventilation), excessive or insufficient humidity, temperature fluctuations, and recent remodeling can all affect the quality of air inside a building. Indoor air quality can be affected by cleaning supplies, pesticides, or other airborne chemicals, as well as by mold, dust from renovation, and other particulate matter. Bacteria, fungus, and other microbial contaminants can cause serious health risks without attracting much attention to themselves. Other harmful contaminants include dangerous gases such as carbon monoxide, radon, and volatile organic compounds. For people who spend most of their time indoors, indoor air quality is becoming an increasingly more concerning health hazard than outdoor air, as indoor air is often significant more polluted.

Some of the primary methods for improving indoor air quality include air filtration, the use of ventilation to dilute contaminants, and the control of air sources. Increasing the frequency of effective turnover of interior air (by replacement with outside air) is a simple and controllable way of quantitatively ensuring the quality of indoor air. Another technique which allows for reduced energy consumption as well as air quality maintenance is demand controlled ventilation, which utilizes carbon dioxide sensors to control the air replacement rate dynamically, based on building occupancy.
