What Our Customers Think

“My husband Robert and I could not be happier with your company. From start to finish, everyone involved in selling and installing knew all information to answer any question or concern we had. Everyone was friendly and very professional. I rate your company with the best we have ever had, and your installers Cliff and Tim were amazing. I can’t tell you how great it was to watch someone who cared about the work they were doing. We could not find one thing we were not happy with. I definitely will recommend your company to all friends and relatives. Thank you!”

“You always hear the complaints, BUT YOU NEVER GET ENOUGH KUDOS ABOUT EXCELLENT SERVICE. I would just like to commend SGI from Jeff, who sold me and told me what SGI would do for me, to Ray and Tim who did exactly what Jeff said SGI would do. It is such a pleasure in today’s market to work with a company that is prompt, tells you what they are going to do, and then does it. They even put my landscaping rocks back in place. Thanks!”

– Michael, Lansing

“The team assigned by SGI did a great job with the installation of my new Rheem home furnace. Ray & Cramer were on time and put in a long day to complete the installation in only one day. I was pleasantly surprised with their efficiency, as I did not know if that would be possible in only one day. They were professional & considerate during installation. They worked dilligently to install the new furnace, humidifier & heat ducts to the second floor. This is the first time the upstairs has felt comfortably warm, which is a great relief. I also appreciated their thorough & patient instructions regarding new furnace operation as sometimes I need to be told more than once. Again, these young men did a fine job and I will highly recommend your company!”

– Barbara, Eaton Rapids

“I want to let you know that your workers Wayne, Randy & Jared did a fine job at my house. They installed a furnace, A/C & hot water tank. They were polite, neat and hard working all day long. They kept on course and kept me informed about everything going on. The electrician came and did the work outside for the A/C condenser and Randy came back to test A/C running. We are very satisfied with the products and their installation! Thanks!”
