Air Quality Technicians test and inspect heating, vent, and air conditioning equipment to ensure that the air quality meets safety regulation and standards. They provide preventive maintenance and mechanical repairs to buildings' HVAC systems. Organizations that own high-occupancy buildings may hire air quality technicians directly, and contracting companies may employ technicians to service numerous clients' properties. Some technicians may also be employed to install related equipment, such as fans, motors, and pumps. A high school diploma is typically required, and preference is given to those with the proper licenses and certifications as well as direct experience in the HVAC industry.
Job openings for air quality technicians can be found through typical channels like online job boards such as Indeed, Craigslist, and CareerBuilder, as well as through local HVAC contracting companies. Vacancies can also be found on the career sites of organizations that own high-occupancy buildings, such as universities or government agencies.
The interview process will focus on your technical knowledge and mechanical aptitude. You'll be expected to clean ducts, as well as repair and possibly install HVAC equipment. You'll be assessed on your aptitude with machinery and both electrical and mechanical aspects. Your ability to work as a part of a team is important too.
To prepare for an interview for air quality technicians, take stock of all the kinds of machinery that you've worked on as well as the equipment that you've used to repair and install HVAC systems. Even if you don't have direct experience with some of the listed systems, you can demonstrate your flexibility and adaptability as it relates to your ability to learn on the job. Think about times when you proactively learned about a mechanical system. What questions do you ask and why? Illustrate how your process information to effectively learn a new system. Customer service may be an important part of the job if you're expected to service individual residential properties, so think about ways that you maintain a positive attitude even during stressful situations.
