The project was top notch. Not only did they show up on time, but they finished the project quickly and were willing to reschedule times to accommodate our schedule. Final project turned out great!

Lack of Experience. Unreliable and Dishonest. Do your Due Diligence. My Husband and I hired this company and I use that term "lightly" , to replace the capacitor in May of 2017 on our AC unit. Because of some inclement weather he failed to check the amp draw on the compressor fan that same day. We noticed the air coming out of the vents in our home would be cold one hour and warm fan air moments throughout our day. We dismissed it for awhile and then while doing lawn work near the AC Unit outside, My husband noticed the fan stopped and then would start again. We immediately called the owner, Gary O'Brien and notified him. He scheduled to come out and look at the unit two days later, not very reliable for a business owner to make us wait on work he says "he guarantees". However we were patient. He arrived on August 2nd, 2017 and mentioned the amp draw was running high and that he had failed to measure it in May of 2017 because it was raining. By his own admission, he admits failing to do this that day, but expects us to now pay him to replace the fan motor, the charge for a service call and labor on a part that should have been replaced in May. Because he was afraid to get wet. Prior to making the appointment I remember mentioning that the weather was to be overcast that May day and did he want to reschedule. His response was quite sarcastic, with a "I know how to use an umbrella". Some people have a dry sense of humor, so I just let it roll off my back. However seeing how this turned out, I guess he should have Rescheduled. He did not Replace the Fan Motor. He did not Guarantee his work and was "Not Willing to Be Held Responsible" for "Neglecting" to do a Task we Paid him a Service Fee to do. Be very Careful hiring this Contractor. He may Nickle and Dime you to keep coming out and Lining his Pockets instead of Diagnosing the Problem up front. "Do your Due Diligence". "Be very careful". Know your Contractor. Gary O'Brien is Inexperienced, not reliable and neglects his Responsibilities. Gary O'Brien should be held accountable. For us it was a costly mistake . Do not hire Gary O'Brien"

Gary responded very quickly to my request to replace a defective thermostat (same day). His repair was fast, professional and he's a good guy. I would not hesitate using him again.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
