5.0 Garrett J. Chandler, AZ

I would HIGHLY recommend Cornell and CJB to anybody in need of HVAC services. After receiving the worst possible service from my warranty and some of the larger companies in the valley when my AC did not work while it was 100 degrees out, I reached out to CJB and he fixed my unit THAT DAY. no BS, friendly, and extremely knowledgeable, he came to my house at 6pm(!) same day, and stayed on my roof until after midnight to get us working AC (we had a new baby in the house). Is he a hero? Tough to say. But he certainly went above and beyond and I will never reach out to another company with my business. Dont waste your time, just call Cornell and he will take care of you.

5.0 John+t R. Chandler, AZ

I would highly recommend CJB Comfort for any AC Problem. Mine was a broken motor in the middle of the night. Cornell fit me into his busy schedule and fixed it early the same day. He was very professional and efficient. He was excellent at explaining what needed to be fixed. I'm very happy with his work John

5.0 Lisa P. Tempe, AZ

I met Cornell at my work awhile back because he comes and works on the residents ac there. So I knew he was a reputable guy. So when I needed an honest, hard working ac guy I thought of him. I emailed Cornell that night the next day he came out and looked at our ac and told us the problems , quoted us a price and had it done with in a hour. Cornell is a honest, efficient, hard working, reasonable guy that I would highly recommend. He will be my ac guy from now on! Thanks Cornell your the best!

5.0 Thelma R. Phoenix, AZ

Cornell was great. He did the work efficiently and even suggested moving my drain so water didn't splash on our entrance. He made sure everything was working before he left. Easy to work with.

Response from Company:

Thank you so much Thelma. We like to keep our clients happy even after we're gone!

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.
