What is The National Air Duct Cleaners Association?

Posted on | by admin

The National Air Duct Cleaners Association (NADCA) was formed in 1989 as a non-profit association of companies engaged in the cleaning of HVAC systems. Its mission was to promote source removal as the only acceptable method of cleaning and to establish industry standards for the association.

Air Duct Cleaning Standards

Since the EPA does not certify air duct cleaners, consumers are glad to know that the NADCA exists to provide comprehensive information to both consumers and providers. NADCA currently holds the highest standards of service and only certifies those providers with the knowledge to perform professional air duct cleaning.

Air Duct Cleaning Certifications

NADCA also provides the following certifications:

  • ASCS Certification: Air System Cleaning Specialists
  • CVI Certification: Certified Ventilation Inspectors
  • VSMR Certification: Ventilation System Mold Remediators

Air Duct Cleaning Checklists

NADCA also provides consumers and providers with checklists to ensure quality of service.  All members are required to perform work in accordance with NADCA Standards. As part of its Quality Assurance Program, NADCA provides information about how to select a qualified contractor along with pre – and post-cleaning checklists to ensure that total system cleaning is performed.  Reviewing the checklist is an excellent way to ensure quality of the air duct cleaning.

Questions to Ask Before You Hire an Air Duct Cleaner

Posted on | by admin

Hiring a qualified air duct cleaner is important because a poor job can actually make indoor air quality worse.  If you are concerned with healthy indoor air, make sure to ask potential air ducts cleaners the following questions.

How Long Have You Been In This Business?

Experience is important in performing a quality job. Ask the number of years that the company has been in business.  Ask the number and types of air duct cleaning jobs that the company has performed to get a feel for their experience level.

Do You Specialize In Air Duct Cleaning?

Ask the company if they specialize in air duct cleaning, or if it is one of several services that they perform.  Companies that specialize in a service are really good at one thing… rather than being mediocre at several things.

Is The Company NADCA Certified?

The National Air Duct Cleaners Association is the group the EPA recommends to find qualified air duct cleaning contractors.. The NADCA is an excellent resource for consumers because it provides a list of qualified service providers, tips on how to choose a provider, and a checklist to ensure a good job was done. If possible, hire a company that is a certified member of NADCA.

Are The Employees Screened?

Ask if the employees have been screened by a thorough background check.  A background check will ensure that the employee does not have criminal convictions.

Ask For Referrals

Ask for referrals or testimonies. Find out if the technicians did a good job, if they had any complaints, if their home was respected, and if the technicians cleaned up after themselves.  The air duct cleaning contractor should be able to point you to several current sources of referrals or testimonies.
