    0.50 Ming C. San Francisco, CA

    Hired for ceiling light, Finish part of the job missing part could not not finish all. They needed to order part and come back later. After the week waiting part comes, They tried to charge me for this job that is unfinished as same as the first time!!

    Response from Company:

    Hello Ming, I do apologize that you were unhappy with the service. I reviewed the work that was done back in September 2019 since it was so far back. The total charge was for 1.15 hours and materials. Here at REFcorp we never charge a 2 hour min and parking fees. I will follow this with a phone call and I will be more than happy to go over any issues you may have had. Thank you and have a great day!

    Thank you Anthony! We look forward to working with you again!

    5.0 Allan K. San Francisco, CA

    Resolving problems with the existing wiring was efficiently accomplished and the Ecobee installation then proceeded smoothly.

    5.0 Larry H. South San Francisco, CA

    I had set up an appointment with Priscilla on a Wednesday and the following day had Carson come by to run a new wire from my furnace to my thermostat. I recently purchased a smart thermostat and like most older homes lack the C (common) wire. I looked into the fast common wire makers and read through some reviews and decided that for the cost to purchase that and trying to figure out the wiring that I would hire a pro instead. Carson arrived on time and got straight to work. He was polite and accommodating - entering the house he took off his shoes each time. And this happened multiple times to get to and from the car, the crawl space, and garage. I definitely appreciated it. I would highly recommend and hire again.

    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.
