Best Heating & Air Conditioning / HVAC In Central Islip

“Hiring GMG HVAC to service our home is the best decision we could have ever made. Joe is seriously the best, most friendly person, and one who is knowledgeable in all aspects of home ownership and construction. Every time he has come out to our home, we are immediately put at ease and know that our problem is going to be fixed correctly.“

“We had a home renovation taking place where we needed new ductwork added as well as consideration taking into what to do with the existing system. Mike and Energy Mechanical took a very pragmatic approach in providing a few "here's what I would consider if this was my house" options. On time, in coordination with our GC and never an issue getting a hold of them.We are very happy with the final results...so much so that our neighbor ended up using Energy Mechanical for HVAC install needed as part of an addition they did shortly after they saw our project completed.“

“Kevin and his crew were professional, knowledgeable and work was completed in one day. Kevin replaced my old AC unit with a Rheem 3 Ton 16 SEER Air Handler and Condenser. Installation included replacement of all ducts and vents and included an AprilAire 20 x 25 Merv 11 return. Unit was installed at the end of August and it was up and running by 5:00 PM the same day. Kevin and crew worked neatly and cleaned up as if they were never there. Price was competitive and all materials used were high quality. I would recommend Madison & East Mechanical for all your AC needs.Service: HVAC duct & vent installation“
