I really can’t say enough good things about Gregg and GM Mechanical Services. I knew I was in good hands from start to finish – courteous, professional, and fair – more like I was dealing with a friend than a business. Expert quality work; I recommend without reservation. Thanks again.

I have used GM Mechanical Services, Inc. for a number of years for all my HVAC and property repair needs. I have a rental property business where it is important to me to have repairs done on time and on budget. Gregg at GM Mechanical Services, Inc. is very professional and knowledgable and gives me the confidence that the job will be done right. He is very efficient and above all very friendly and I would not hesitate to recommend him to anyone.

Dear Gregg, It means so much to me that I can count on you, every spring, to check-out and repair my aging HVAC unit and keep it running another year! I appreciate your willingness to drive all the way to downtown Greenville to do this for me, I trust you to do the work efficiently and competently, and I know you will charge me a fair price. Thank you so much!!

Gregg at GM Mechanical Services, Inc. has helped me several times over the years with my air conditioning systems and always does a great job. Since I can’t always be there to meet with him for the repair, knowing I have someone in my home I can trust is priceless. GM Mechanical Services, Inc. recently replaced my upstairs system when it failed and Gregg helped me select the perfect system at a great price. I wouldn’t call anyone else!

Never have I felt so comfortable around a contractor working in my home. My new tankless water heater installed by GM Mechanical Services, Inc. is fantastic and I was especially impressed with how clean they left everything. Highly recommended!!

My wife and I called several companies in the area for an estimate when our heating system died on the coldest day of the year. Choosing GM Mechanical Services, Inc. to replace our furnace was an easy decision to make. Thanks Gregg.

My husband and I began calling on Gregg Merck and GM Mechanical Services, Inc. over seven years ago. Since then we’ve recommended GM Mechanical Services, Inc. to friends and family because we’ve always gotten great service at a fair price. Gregg is efficient, on time for appointments and has even worked us into his schedule when we’ve had emergencies. We definitely trust Gregg with both of our Trane systems and know that we can always count on him.
