Mr. Duct is Chicagoland’s Most Trusted Residential Air Duct Cleaner
How to Select a Residential Air Duct Cleaner
The Environmental Protection Agency (EPA) recommends that if you are going to have your air ducts cleaned, you have it done by a company that holds membership and certification with the National Air Duct Cleaners Association (NADCA).
Being a member of NADCA guarantees that a cleaner will follow a set of ethical guidelines and will service the entire HVAC system. The following points reflect on how to determine if the air duct cleaner you are considering is the right match for your home.

- Can the company show proof of NADCA membership and certification?
- How long has the contractor been in the residential HVAC system cleaning business?
- Can the contractor provide you with evidence of the current Worker’s Compensation and General Liability Insurance coverage? (Ask for Certificate of Insurance)
- Does the contractor posses the proper Licenses that are required by your city or state to perform the work they are proposing? (Not all cities or states require licenses)
- Will the contractor provide you with 3 to 5 customer references with phone numbers for which they provided service in the last 30 days?
- Will the contractor conduct a thorough inspection of your HVAC system PRIOR to performing any work and alert you to any problems? This is required by the current NADCA Assessment, Cleaning & Restoration of HVAC Systems (ACR) Standard.
- Will the contractor provide you with a means to conduct a visual inspection at any time during the air duct cleaning? (Mirror and flashlight, camera or other remote visual systems.)
- Will the contractor be cleaning the complete HVAC system, including coils and fans?
- Will the contracting company actually do the work? (Some companies subcontract the work to independent contractors. You will want to apply these guidelines for subcontractors as well.)
- Is the contractor giving you a guaranteed price before the inspection? This may expose you to extra costs. Finding mold in the HVAC system, damaged fiberglass insulation, cleaning or treating cooling coils may become add-on costs.
