    Very informative on questions by me

    2.0 Leslie F. El Cerrito, CA

    Dennis was polite and fast. He put his mega vacuum over the furnace intake vent and that may be enough to create *negative pressure*, but the vents still smell bad. Previous service used the vents elsewhere to greater effect.

    5.0 Vetzi W. San Ramon, CA

    They were very courteous they were on time.

    5.0 Franz E. Brentwood, CA

    Bay Air flow, and the owner / operator Dennis, is absolutely amazing! He knows his stuff and will NOT up-sell you on something you don't need (AMAZING, and almost unheard of personal and business character). I would highly recommend Bay Air flow for all your duct cleaning, dry cleaning and duct repair needs!

    5.0 Billy E. Brentwood, CA

    5.0 Jon A. Benicia, CA

    5.0 Dawn S. Martinez, CA

    Dennis contacted me immediately and we set up an appointment that morning. He was prompt and on time. He is very polite and efficient. He got right to work and got the job done quickly and completely. I would definitely use him again and would not hesitate to recommend him to anyone needing his services.

    5.0 Bonnie L. San Ramon, CA

    Dennis was patient to answer all my questions and concerns. He was thorough in walking me through the process and was knowledgeable in the service he provided. I plan on having Bay Air Flow to conduct annual maintenance for our home. Thank you, Dennis.

    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.
