Choosing The Right Air Duct Cleaning Company

Choosing The Right Air Duct Cleaning Company

How to Select a Residential Air Duct Cleaning Contractor

  1. Can the company show proof of NADCA membership and certification?
  2. How long has the contractor been in the residential HVAC system cleaning business?
  3. Can the contractor provide you with evidence of the current Worker’s Compensation and General Liability Insurance coverage? (Ask for Certificate of Insurance)
  4. 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)
  5. Will the contractor provide you with 3 to 5 customer references with phone numbers for which they provided service in the last 30 days?
  6. 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.
  7. 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.)
  8. Will the contractor be cleaning the complete HVAC system, including coils and fans?
  9. 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.)
  10. 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.
