I wanted to express my appreciation for the professional Job done by Jason! He was polite and remained positive. He worked until the job was done and we had Air again. Temps in our home was hitting over 90 degrees and we have pets. Please thank him again for us. James J. Willard

James was very nice and very professional. Since the first phone call to the actual service appointment, the customer service has been some of the best in recent years. Very thorough and I was explained everything. The price was better than some others we've tried. I'm sticking with GSM!!!

GSM performed a repair on our AC and did an excellent job--prompt, knowledgeable, and courteous. They also did our routine maintenance and were prompt and did a great job. Thanks for your excellent service technicians and your office staff.

Had my unit serviced for the first time with GSM and it was a very pleasant experience. Customer service was very professional and nice. Zach and Holt were very sweet and knowledgeable. Had to have some repairs done unfortunately but they both came back the next day and did a great job! Overall a very nice experience. I would definitely recommend GSM.

I always have wonderful experience with my GSM services. My service advisor Amanda Bowers did a great job with my summer tune up. She provided me with a quote for services she thought would extend the life of my two outside units that are getting old and also provided me with information on an air treatment system due to my concern of having so much dust in our home. I know I can always count on GSM in the event of an emergency and the service is top notch!
