  • Thanks Penny! Your company was very accommodating and easy to work with long distance.
    We appreciate all you did!


  • Thank you.It’s a pleasure having your reliable service.


  • 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.


  • 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.


  • 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.


  • 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.


  • 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!


  • 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.


  • 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.


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


  • 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.

    Joe & Patti

  • We greatly appreciate the excellent services you provide to our home warranty holders.


  • Thank you for installing my air conditioner so fast. Your service staff was excellent.


  • It is to late in the day to call, but I wanted to tell you we called to have a furnace worked on at one of our rentals. Not only did the tenant text me to tell me how kind Penny was, he texted me to say how extremely good Tom was. Tom took time to walk our tentant through the new thermostat (I asked to have it installed). Our tentant was so grateful. I wanted to say thank you for everything you and your crew do to help us


  • Thank you for the good work. I love my new furnace, and I will recommed you to others.


  • Good morning Penny.Our A/C stopped working yesteday and Brian was out within the hour to get it running again. He did however, identify that it's not cooling like it should be, so he's going to do some research into it to see how to go about addressing that.Nonetheless, it worked good enough to get through the night. Thanks for the great service from GMS!

    Milda S.

  • Just a short note to tell you how much we appreciate your prompt services. In particular, I would like to single out one of your field representatives. Brian Neubauer has been extremely helpful and conscientious in servicing our church, Trinity Evangelical Lutheran. I cannot say enough about how he goes about his work always looking to save us money and make our systems more efficient. Brian is very easy to work with and tries to help me understand the systems, and because I am not that mechanical that is no easy task. Whatever you pay him you are getting a great deal. I would also say that the entire staff that we have had work on our facility has earned the reputation that your company has achieved. Thank you and we look forward to working with you in the future.

    John W.Buss

  • Thank you Penny! You and Tom have been great and I will keep using Gartman. I understand some of these things can take time to track down. Thank you for your responsiveness.
