    5.0 Rama N. Pflugerville, TX

    JC explains every technical detail in layman language. Very impressive work. He is on my speed dial for any AC work.

    3.0 April C. Jonestown, TX

    The person that came out to do the quote for the new furnace and AC was fantastic. O2 Kool quoted us a great price! Then the installers showed up. I am not impressed as we had some leaks in the ducting, they did not offer mold resistant material for the plenum box and they could not think outside of the box when it came to installing our vent pipe. They were supposed to come out to do the follow-up. We received a letter that gave a call by this date or we will not come out to follow up. We were not home and did not receive the letter until too late. I called several times but did not get a response. We have two more units that need replacing. I am happy I did not quote with them for all three!

    5.0 Todd T. Georgetown, TX

    Let me tell you a story! I woke this morning with my wife telling me her mother’s heater wasn’t working. Being an ice storm just hit the Central Texas Area we were concerned. I immediately opened my Home Advisor App imputed the information and almost immediately CJ from O2 Kool Refrigeration and AC called. He was in the Marble Falls area and informed me that it would be about an hour and a half before he could be here. Knowing what kind of weather we had and how busy these guys were I said it was a deal. Wow! They showed up made a few adjustments to the unit got it working and then refused any pay since they didn’t have to do any repairs. Talk about wonderful customer service, these guys exemplify Professional refreshing customer service. I immediately put them in my phone contacts for future use. Bravo and Thank You for taking care of my mother in law.

    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.
