• Brian gave me his cell phone number in case my EAA renters had problems with the AC. Above and beyond service! Just wanted to let you know how good he is.

  Mark

• We were very impressed with Brian’s work, conscientiousness and promptness. He was very polite also. It’s nice to be the recipient of such great service.

  Susan

• My husband was hunting and my hot water heater went out. I called Gartman and they were able to come the same day and replace the hot water heater. Very pleasant to deal with and never made me feel like it was a problem for them to come out and help me, especially on a Saturday. I will forever use their services.

  Lynn

• A young gentleman came over and did a great job cleaning the boiler and checking the performance. If you have a bunch of young men like that your business is poised to do very well going forward. I feel safe, I will be calling you guys again in late spring to check the AC.

  Mike

• I just wanted to include a short note to say thank you and express how happy I was with Chad’s service. He was extremely nice and reassuring and made a stressful situation much easier to deal with. He was also great about explaining what was wrong and what he was doing. Thank you for such great service!

  Lori

• I just want to say thank you for the wonderful work you did on my furnace. Your men Jason, Matt, and Chad were great working together and explaining how and why they did the things they did.House is back to being toasty warm again.

  Judy

• I really appreciated the great, efficient service on December 31st when Jake O came to “rescue” me from the cold. He did an excellent job and was very polite – he knows furnaces. Also, I appreciate being on your list for Fall maintenance.

  Mary

• Thank you, it’s pleasure having your reliable service.

  Jayne

• On behalf of my wife Patti and myself, we want to let you how happy we were with the service. GMS has done work for us in the past and we have always been very happy with the results. It goes without saying, we will not hesitate to recommend GMS to others looking to update their HVAC systems. Feel free to put our name on the list of happy customers.
