GMG HVAC Inc.

Excellent service. We had multiple technicians review our issue and all were unable to determine what was wrong. Andrew was able to pin point the problem and fix our entire system in just a few hours for a very reasonable price. We will be using GMG from now on!

Great experience working with Andy. So professional , excellent quality cleaned up after the work was complete. Excellent experience overall. Highly recommend working with GMG HVAG Inc. System working nice and cool ... Thanks !!!

After looking at many cooling services near our area, and ended up choosing GMG HVAC inc for their great reviews. I’m glad I choose this as the person who worked at our house (Andrew) was very professional and worked very throughly. I would definitely recommend this company.

What a fabulous experience I had with GMG Hvac Inc. That in itself is amazing to say when your a/c breaks down in July. Came the day I called, came on time, zeroed right in on the problem, fixed it and charged a very fair price. Andrew called the next day to be sure all was still well and comfortable in my home. I looked at the reviews on this company before I called them. Saw they were known for their honestly. That’s what I wanted and certainly what I got - in addition to professional, quality service.

Andrew and his staff saved the day. When we lost PSE&G power for almost 7 days When the power came back on it blew out one of our 5 ton A/C Units 2 days before our sons wedding. We immediately called Andrew @ GMG HVAC and he was able to secure a new 5 ton A/C unit the next day ....one day before the wedding.... while doing our new A/C installation PSE&G Lost our power again. Our Suffolk CountyLegislator Rob Trotta Heard about our misfortune, called me and he then followed up with PSE&G. While this is all going on Andrew & Staff are installing the unit hope that we get power again. Legislator Rob Trotta came through big time, we got electric and by 9PM GMG HVAC got us going.
Additionally, Andrew said if didn’t get power until early Friday morning to let him know so that he would finish the installation before 7am. I couldn’t ask more from Andrew, even if he was one of our sons. And special thanks goes to Suffolk County Rob Trotta. Keep the Faith

Professional service at a reasonable price. Customer service is excellent. They understand my needs and get the right people to do the job. They also communicate well with my GC regarding residual painting that needs to be done. They always clean up after themselves leaving job site clean and neat. They pay attention to details.

Incredible service. Honest and reliable. Ended up needing a new upstairs unit....affordable! 2 service guys came and within 6 hours my new unit was up and running. They were clean and the nicest guys. The owner is a sweetheart who is very knowledgeable and honest and very easy to work with. Considering my AC konking out mid July which is the height of their season, this process was quick, easy and painless! Totally recommend!

Quick and painless repair on my HVAC. Jocelyn is very responsive and Joe is very professional. I received multiple options which was incredibly helpful. I'll have them bookmarked.

Great service! Andrew took my call at 7:30pm and came within the hour, figured out the issue and got my heat up back again. Also VERY AFFORDABLE. He offers a 30 day labor service warranty meaning if he fixed somthing and it still gave a problem, he'll come back to fix for free. Awsome stuff. He knows his stuff and will highly recommend him.

My heat was out. I called on a Sunday morning, reached Andrew immediately and they were here within an hour. As soon as the parts came in on Monday, GMG was back and everything was fixed. The guys were so nice and the price is totally reasonable would definitely recommend them. Thanks Andrew!
