5.0 James M. Homosassa, FL

After getting quotes from several large company vendors, I got a quote from Diamond G A/C INC. They are a family owned business, with 30 years experience. I was thoroughly pleased with everything from start to finish. No pressure at all, came I more than $4000 less ( obviously due to much lower overhead than the large companies) After installing they arranged the inspection time for us, the inspector approved all the work in about 5 minutes. The owner of Diamond called me to follow-up if everything was working fine (it is),called me to see if inspection went OK. This experience was exemplary a company that takes great pride in going the extra mile. Highly recommend!!!

Brian and his sons, are extremely knowledgeable in many many areas of electricity, a plumbing, of any kind. Heâ s prompt, heâ s extremely polite and offers. Many very useful suggestions. Gets the job done cleanly an expertly.. heâ s extremely fair and kind with his billing, and if you ever have a real emergency like I did when it was in the 20s out here in Brooksville, my heater was not working he came and worked when it was pitch black outside and got that up and running for me. As an elderly person, this man is totally invaluable. I totally recommend him! Youâ ll be so happy you did.

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.
