Review by in Manhasset, NY
Project: Repair Natural Gas or Propane Furnace / Forced Air Heating System
Another great referral from Home Advisor! When I got in touch with Andrew, the owner of GMG HVAC and told him I had no heat and the house was freezing he said I will get someone to you between twelve and three. True to his word at twelve forty five he called and said Joe will be there in a half hour, and he was! Joe is very friendly and efficient and had the house warming again in an hour. A definite referral!

Excellent experience. Andrew is extremely knowledgeable and fixed a very complex wiring issue in just a few hours. Great pricing. Thank you so much Andrew! We will be using GMG from now on.

GMG takes shortcuts and the results show it. They did an A/C compressor and blower replacement. They also replaced some metal duct work with soft duct work. They simply loosely stuffed the soft duct work into the blower housing without any collar or duct tape. It fell out easily and sucked dirt in from the attic. In another area, the round soft duct was attached to a larger rectangle opening and there was a large opening where the cold air was blowing into the attic. The compressor base was installed on WOOD that would rot. I replaced it with slate. When I informed the owner the installation was bad, he replied my expectations were too high. I am having someone else correct the work as they can't be trusted. I have PICS if you want. They also did not apply for the necessary town permit. They finally did and repeatedly said they would send it and the final town sign-off. Nothing was sent and I picked them up. So, check their work and permits.

I found this company on Home Advior yesterday. I spoke with Andrew and he assured me that they would get to me today. Andrew and John arrived on time and our problem was very tricky, it turned out it was electrical and not the AC. The AC ducts were electrified and melted, Andrew and John replaced it but went 10 steps ahead to help my husband look for the electrical issue. Andrew and John were professional, clean and efficient. Andrew also had a baby yesterday and still came today!!! I HIGHLY RECOMMEND this company.

Explained everything and suggested no need to spend too much, to change the whole unit, but simply a clean up will do for the time being until it really gets bad.

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.
