Testimonials for GSM Services

Dramatic improvement in cooling effiency of my "man cave".  So glad I went with the thermal shield and foam board insulation

Thank you so much for your quality of work, quality of workers - simply - Your quality of work!

The service was great.  The service guys for the heating and air conditioning was very generous.

GSM did a terrific job at my house. I am very pleased with the results and have quickly noticed the difference with the heating of my old house. GSM will definitely be used for my HVAC needs in the future also.

I already referred you to my neighbor. She has been a customer ever since.

Once again, very pleased with our experience with GSM. The company is very "customer friendly" and the job is not finished until everything is perfect. They aim to please and they do!

Great people to work with, they know what they are doing, explained the whole process in stages, easy to understand.  I didn't realize the complexity of the job.  Neat appearance, trucks look great, the crew was really nice also, will recommend your company to anyone. Also your company was not pushy which I dislike.  Steven Grant and Taylor Brewer were very helpful and answered all questions.

We are new in the area and found GSM through Duke Energy. The tech came on time, got the job done efficiently and to our satisfaction. Thank you!

My experience with all the personnel was positive. I was impressed by the Google Reviews and testimonials. My energy evaluator was a consummate professional and gentleman. The evaluation,work proposal and agreement went well. My only concern was that the work crew didn't seem to be familiar with the installation process of one particular product they were installing. When I called and asked my original energy consultant to check the installation of the product, he was honest and upfront and said they didn't install the product in the proper way. He had another crew come out and make adjustments in the installation of the product. In the end, everything was fixed and handled in a professional manner. I appreciate the attentiveness and prompt response from all involved. I'm a little confused on why the 1st crew was not familiar with that particular product installation. I would consider using again primarily based on my energy evaluator,Richt, and his honesty,respect, and response to my concerns.

I personally can't think of anything! Thanks- *James Lewis is the Best!!

The service from start to finish was excellent. We were very impressed with the entire experience!

GSM does work for us, our son, my mother and many of our friends. You guys are professional, informative, courteous and respectful of our home. We are very comfortable having you guys work in our home.

I had researched the product over the internet and was very impressed by how your rep. presented and explained to me what I needed and what would be more cost effective. GSM seems to care about the customer and I would gladly recommend you guys to anyone.
