When it's time to service your heating, ventilation, and air conditioning (HVAC) system at home, you'll likely look for a company with certified technicians. Hiring someone who is certified by NADCA ensures you're getting work done not just by a legitimate company, but by someone who truly knows air duct cleaning.

What is Certification?

When someone is certified in their trade, they have completed specialized training and passed evaluations to demonstrate their expert-level knowledge of their trade. When someone achieves certification, they are able to produce proof of their achievement, usually via a certificate (hence, certification) or some other official document.

Certification programs usually require professionals to re-certify every year or every few years. Professionals must take continuing-education courses and complete additional exams to show that they are up to date on the latest trends in their industry.

Many trades have different certifications that workers can achieve, but they're not all the same. Each certification is focused on one aspect of the trade. In HVAC, this means that technicians may get certified in everything from energy efficiency to environmental protection, mechanical components of HVAC systems, and, yes, air duct cleaning.

Air Duct Cleaning and Certification

HVAC technicians and contractors who are certified by NADCA have completed advanced training in HVAC system hygiene, meaning that they have a better understanding of how HVAC systems get dirty, how to clean different types of ductwork, and how to verify that air ducts are in fact clean after a job.

The value in hiring a NADCA-certified technician is that you can rest assured that your money is well-spent; the job will get done by someone who truly knows the trade and how to do the work properly. In addition, the continuing-education courses that technicians must complete to stay certified each year ensure that any NADCA-certified technician is skilled in the latest equipment and techniques in air duct cleaning.
