    5.0 Anita M. Pleasanton, CA

    Jake was an excellent technician. He was an expert and he did an outstanding job with the water heater. He explained everything in detail and put my anxiety to test. I am very satisfied with his work and wish more success in his future endeavor. Dr. Anita Malhotra

    Harris Water Heaters and another company both came out and did an on site inspection and verbal quote. Harris later gave me a paper quote with all the discussed details and with the same price. The other company gave me a paper quote missing some details and the price was increased significantly. Harris did the job and did everything they said they would do.

    My husband has been in Real Estate for over 40 years, and we have never had service like this before. Exceptional Service doesn't even do them justice. Bryan the owner answers the phone. Jake that came out gave us 6-star service. It is always a pain to have something break, but with Harris Water Heaters they made it a pleasantly happy ending. PG&E came out today because they didn't my cancelation and they said harris Water Heaters did excellent work.

    5.0 Debbie B. Hayward, CA

    Responsive, timely, thorough, accurate and ... patient and kind answering questions. An A+ business - family owned and operated. I would definitely hire them again!

    I called at 10:30 am and the work was done before noon, quick and friendly.

    5.0 Bill E. Moraga, CA

    Bryan was great! Right on time and all done on schedule. Knew a good deal about the products they sell. Very competent installation too. Didn't try to upsell; we got just what we wanted.

    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.
