5.0 Valerie P. Gilroy, CA

They called in an instant after I placed my request. The dispatcher was efficient, professional and made me feel like the most important call she had all day! Her name is Chelsea. The technician arrived promptly at the beginning of the time window. His name is Belsin. He was courteous and professional in appearance and every other way. His kit was confidence inspiring. Tidy but well stocked and so was his truck. He performed the repair rapidly and then did a couple of quick maintenance things that werenâ t part of the repair. He also educated me while he worked. I will be a regular customer from now on. This experience deserved 10 stars.

5.0 Hanh D. San Jose, CA

Great service and he took time to explain everything to us

5.0 Sally S. Belmont, CA

Great job

5.0 Kevin C. Half Moon Bay, CA

I needed to have techs come back to fix 2 issues after the install, one was a loose wire connection going to the fan asm. and the other was a rain / water leak from the roof hood covering the air input / exit. In both cases, the techs found and fix the issues in a timely manner and their troubleshooting was spot on¦. The install did take time but it was impressive to watch them remove a 40 years old unit and install a new one.¦

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.
