    Did a superb job of cleaning the vents and duct work. Don't be fooled by the low cost coupons from other businesses. These guys know their stuff

    They were very professional and took their shoes off upon entering my home. They asked if there was a pet that they needed to take precautions of getting out of the house. They worked in the bathroom first so that I could put my cat in the room so she would be safe. They explained everything that they were going to do and answered all my questions. I have already handed out their business cards already. I will definitely call them when it's time to have my vents cleaned again!

    Cornerstone IAQ is simply excellent. They arrived exactly (to the minute) as they said they would, showed me before and after duct pix, and offered sound advice on other related actions I could take. They are worth every dollar spent. I recommend them to anyone needing their HVAC ducts cleaned. Hats off to Mike and Jason....

    Mike and Jason were true professionals. They walked through the house and quoted a price before work began. They explained what they would be doing and provided appropriate discussion and informative pointers along the way. We would highly recommend them.

    Seal of Approval

    What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

    1. Verify Trade License
      HomeAdvisor checks to see if the business carries the appropriate state-level license.
    2. Verify Insurance
      As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
    3. Verification of State Business Filings
      For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
    4. Criminal Records Search
      HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
    5. Sex Offender Search
      We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
    6. Bankruptcy Search
      We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
    7. Legal Search for Civil Judgments
      We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
    8. Liens Search
      We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
    9. Identity Verification (SSN)
      HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
    10. Identity Verification (Reverse Phone Lookup)
      We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
