    5.0 Cat M. Dripping Springs, TX

    In the middle of a record heat wave my AC broke. AC repair companies have been very busy, but 02 Kool assured me they would make it out to me the same day, and did. Tech fixed my AC and had it cooling in a half hour. I can sleep at night thanks to 02 Kool.

    5.0 Michael S. Liberty Hill, TX

    My AC failed in the middle of the night. Next day was going be hell for me and my dogs. 105F. I placed the request to Angie and O2 called me a little after 8 am. Already on the way!

    4.5 Hillary K. Hutto, TX

    Very nice young man. Fixed the problem quickly. Was quick, professional, explained what was wrong and how he fixed it. Showed us the part he replaced. Would definitely use him again and recommend him and Angi.

    5.0 Sharon V. Austin, TX

    Brad did an excellent job repairing our AC. He responded quickly to my call for help. When he arrived he was very polite and professional. He assessed the problem quickly and told me what he thought the problem was. Brad was very honest about the fact that my unit may still be under warranty with the company I purchased it from and that it would be less expensive for me to have that company repair or replace my unit. As the trouble shooting continued, Brad discovered there was a blockage in the drain pipe which was causing the problem, a much less expensive problem than what he originally thought. He blew out the drain pipe FREE OF CHARGE!! My AC is now working like a charm. I was so impressed with his honesty, his skill, and his work ethic that I will be singing his praises to everyone I know. This company is a rare find with old fashioned values you just donâ t find anymore. I will recommend O2 Kool to everyone I know. Thank you Brad!

    0.50 Steve S. Austin, TX

    Repairman couldn't fix the AC problem because he was working on the wrong unit (there are 3 at my house). Once he figured out the correct unit he said that he doesn't have access to parts under waranty. He wanted to replace the whole unit. I had to hire soneone else.

    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.
