Did They Clean My Air Ducts Properly? Post-Cleaning Quality Checker

Use this post-cleaning checker before you consider the job finished. It helps you verify whether the parts of the HVAC system that were supposed to be cleaned are visibly clean, properly reassembled, and operating normally.

This is not a contractor rating tool. It checks the condition you can verify after service. EPA says a thorough visual inspection is the best way to verify HVAC-system cleanliness after duct cleaning.

No email is required. Your answers are evaluated in your browser.

1. Did the provider clean the supply and return ductwork that was included in the written scope?
2. Did the provider show you that accessible supply ducts, return ducts, and plenums are visibly free of loose debris?
3. Are registers, grilles, and diffusers visibly clean and firmly reattached?
4. If the blower / air-handler compartment was included, are the blower area and accessible fan surfaces visibly free of loose dust and debris?
5. If the cooling coil and drain pan were included, do they appear clean and is the drain pan draining normally?
6. If the system contains fiberglass-lined or fiberglass duct material, does it appear intact without new tears, abrasions, or obvious damage?
7. Were any new access holes, panels, or doors closed and sealed securely after cleaning?
8. Is the HVAC filter properly installed and fitting normally after the work?
9. Is the system operating normally after cleaning, without a new noise, airflow problem, error, leak, or loss of heating/cooling?
10. Did the provider leave noticeable loose dust, debris, damaged finishes, or cleanup problems in the work area?
11. Were you given visual verification, photos, remote-camera images, or an opportunity to inspect cleaned components?
12. If the provider could not clean a scoped component, was that limitation clearly explained and documented?

How EPA Says to Verify an Air Duct Cleaning Job

EPA says a thorough visual inspection is the best way to verify the cleanliness of a heating and cooling system after duct cleaning. The provider should be able to show representative components so you can confirm that the system is visibly clean.

EPA's post-cleaning consumer checklist covers the ductwork and plenums, heating and cooling components, blower, fiberglass material, access doors, registers/grilles, filters, and normal system operation. A negative answer can indicate a deficiency worth correcting.

Visible Cleanliness Matters More Than Marketing Claims

NADCA's cleanliness-verification framework likewise treats visible cleanliness as a primary verification method: cleaned HVAC components should be free of non-adhered debris. Before/after photos can help document inaccessible areas, but photography is a verification aid rather than a substitute for actually cleaning the scoped components.

Check Access Openings and Reassembly

Cleaning sometimes requires new access openings. EPA says those openings should be sealed and, where appropriate, re-insulated so they are airtight. Registers, grilles, and diffusers should also be clean and firmly reattached.

If a New HVAC Problem Appeared After Cleaning

A new noise, airflow problem, water leak, error, or loss of heating/cooling after service deserves follow-up. Document when the problem appeared and contact the provider. The checklist cannot determine whether the cleaning caused the issue, and a separate HVAC diagnosis may be needed.

What This Tool Does Not Verify

  • Hidden workmanship that cannot be visually inspected
  • Whether the provider followed every technical standard
  • Microbial contamination or hazardous materials
  • Whether a specific company owes a refund or violated a contract
  • Whether a new HVAC problem was caused by the cleaning

Need a Second Opinion in Dallas?

If the checker identifies important visible deficiencies and you want another provider to inspect the system, you can request a Dallas-area service quote. A second provider should identify what it actually observes and provide its own written scope and price.

This checker is educational. It does not certify workmanship, determine contract liability, or prove that a service provider caused a later HVAC problem.
