The indoor air quality (IAQ) and HVAC industry is a rapidly growing sector within the broader environmental and building services market, driven by increasing awareness of health, energy efficiency, and regulatory compliance. This industry focuses on improving the air people breathe in indoor environments—residential, commercial, and industrial—by offering services such as air duct cleaning, HVAC system maintenance and replacement, mold remediation, air purification, and environmental testing.

As homes and buildings become more energy-efficient and airtight, the need for effective ventilation and air purification systems has become more critical. The IAQ industry plays a key role in addressing pollutants such as dust, allergens, mold, bacteria, volatile organic compounds (VOCs), and other airborne contaminants that affect occupant health and comfort.

With increasing concern over indoor pollutants and energy efficiency, the IAQ and HVAC services industry is expected to continue expanding, especially in areas like Central and South Texas, where climate demands year-round HVAC operation and air quality concerns are heightened by seasonal allergens and humidity.
