    They are not trying to take all your $$


    Hired GS to perform a service on my heaters. John and his assistant were on time and conducted themselves professionally. Ran into a couple issues, which the guys were very able to address and more importantly they explained everything to me. I was so satisfied with their service that I enrolled in their maintenance service plan.

    5.0 Jay J. Absecon, NJ

    Excellent Service, John and Joe were punctual, professional and provided quality service in the diagnosis and care for my system. Took the time to explain what was happening and made great recommendations for moving forward. Signed up for the yearly maintenance agreement because of how they handled the service call.

    Response from Company:

    Thank you and we will see you in the spring!

    5.0 Steve K. Galloway, NJ

    Our 2nd floor heating system would not start. I contacted GS Mechanical and 2 other companies, but decided to trust the reviews. Spoke w/ Rene and she set up the appt 2 days later at my request. John came on time, diagnosed the problem on our unit and left to get the correct part. He returned in approx. 1 hour and we were up and running. He explained everything he did and what the issue was. I will definitely use this company again. Thanks GS Mechanical! They live up to all the good reviews.

    Response from Company:

    Thank you Steve!

    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.
