What Constitutes a Professional Air Duct Cleaning Company?

NADCA CertificationThere are so many air duct cleaning companies that claim to be professionals when it comes to cleaning your HVAC system. To help you steer clear of subpar duct cleaning companies that merely stir up the dust we would like to share with you what we think constitutes a professional air duct cleaning company.

What is the most effective way to clean air ducts?

First, we’ll start with the most effective way to clean air ducts and ventilation systems.

Employing Source Removal methods which require a duct cleaning, contractor, to place the system under negative air pressure through the use of a specialized, powerful HEPA (High-Efficiency Particulate Air) collection unit is the best way to perform the cleaning. The negative air pressure ensures that you’re not just moving the particles from one location of your air ducts to the next.

While the collection unit draws air through the system, specialized, duct safe, agitation tools are inserted into the ductwork to dislodge any debris stuck to interior surfaces of the air ducts. The waste can then travel to the HEPA collection unit, which effectively removes and contains it from the HVAC system and the home.

Industrial Shop Vacs can’t provide a thorough removal of the debris lodged in the interior surface let alone put the system under negative air pressure to remove the particles.

What should I expect from a Professional Duct Cleaning Company?

As with any business, it isn’t enough to just lay claim to being professional. In particular, when it comes to HVAC air vent cleaning, not all duct cleaners are meeting the standards set by the National Air Duct Cleaners Association (NACDA.) NACDA is the regulatory entity for the industry.

The HVAC Inspection, Cleaning and Restoration Association, otherwise known as the National Air Duct Cleaners Association (NADCA), was formed in 1989 as a nonprofit association and comprised of companies that are engaged in the cleaning of HVAC systems.

Their original mission was to promote source removal as the only acceptable method of cleaning and to establish industry standards for the association, and it still rings true today.

Meeting strict requirements set forth by the NADCA is a requirement to be a member. The business must also meet the following provisions.
  • The member must have at least one NADCA certified Air Systems Cleaning Specialist (ASCS) on staff
  • General liability insurance must be maintained
  • The member must agree to clean HVAC air ducts according to ACR, the NADCA Standards, and comply with NADCA's Code of Ethics.
If a company is not going to clean your air vents according to NADCA's standards, they must disclose that to the buyer at the time of sale.

What should I ask when shopping for an HVAC Duct Cleaner?

  • Are they a registered contractor with the state of Arizona? Unlicensed contractors cannot legally access your air handler and thus cannot clean your entire system.
  • Are they a member of NADCA? Hospitals and other businesses depending on a job done right will not do business with anybody that are not members of NADCA. It is, after all, the regulatory entity in the industry.
  • How long does this process take? According to NADCA, cleaning a single AC system properly takes approximately 4 hours with two technicians. If it takes less than that, there might be a problem.
  • How much is duct cleaning for my house? If they cannot give you a straight answer based on the size of your home or business and number of AC units, you should probably contact another air vent cleaning company.
  • Do they sanitize or disinfect? The EPA strictly forbids any chemical being used in your system to sanitize or disinfect an air duct system.

What are the benefits of HVAC Air Duct Cleaning?

Polluted air contains small particulate that is smaller than a micron. Particulates include mold, microbial growth, pollen, pet dander, chemicals, fungi, and bacteria.
