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.
