What Our Customers Think

On 12/28 during a routine annual tune-up to my furnace, a major issue was uncovered with my heat exchanger that required the furnace to be shut down. Considering the fact that it was so close to the Christmas holiday, I was very concerned about how long it would take to get my family out of an unsafe situation and out of the cold.  One of your techs/salesmen name Darin went above and beyond the call of duty to first reconfirm the issue and second to arrange a speedy resolution to the issue.  I made a decision to replace the furnace which was 26 years old.  With Darin’s dedication and commitment, he worked with the appropriate people to install a new furnace in my home on 12/24/20 just in time for Christmas and I am very satisfied with it.  I am leaving out a lot of steps on what was required to make that happen but your Company and people like Darin has gained the highest level of respect from me and I would recommend both to others in a heartbeat.

Earl, from Novi

“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!”

– Gayle, Mt. Pleasant

“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!”

-Carl, Howell

We tried to obtain quotes from 4 companies (one was a relative) to get a new hot water heater, ac unit, and furnace. We got your name from a very good friend in Petoskey MI, who spoke very highly of your company. The quotes were close but we chose HD because of your reputation.

 Yesterday Andrew Dallaire and Don Hunter came on time…actually early…introduced themselves and started the long day of setting up our new equipment. They were friendly and professional. We have a very small closet UPSTAIRS where all of our utilities are and needed some extra time to clean the area up after the dinosaurs were removed. They were very accommodating. Then what looked like the chaos of pipes and threading ended up becoming beautiful, colorful coordination of copper and new white piping. Andrew understood my frustration of not having things in a straight line and put everything in neatly. Don understood the importance of having an AC unit and pad look good as a part of any landscape. 

 They finished ahead of the time they expected, calming explained how to maintain our new systems and enjoyed a laugh and some water with us. We had a few neighbors come by and we proudly raved over your crew and company. We have and have had, a few houses, and your company was by far the best crew we have ever had work on anything in any of our homes. Maybe you should expand your services to all of the trades!!

Bev, Brighton MI

The whole experience with SGI Heating and Cooling was perfect. I wouldn’t change anything.

The gentleman who came out and gave us a quote (Cramer) was very detailed and knowledgeable.  Cramer provided us quotes for three major HVAC systems with options for just A/C, both A/C, and furnace and an option to add a humidifier.  He explained each quote in detail, including incentives, and answered all of my questions.  We chose to replace both the A/C and furnace.  All of the permits and the inspection were handled by SGI Heating and Cooling included in our quote pricing.  There were no hidden charges whatsoever.  Everything was finalized and an installation date was provided.  It doesn’t get any easier than that.

The installation crew (Joe & Don) were prompt, professional, and very courteous.  They explained everything in detail which made me feel very comfortable.  Honestly, it was like I had friends over to install this system.  The installation time was very efficient and professional. When complete, everything was tested and explained, including maintenance tips.  For as much work that was performed, you wouldn’t even know that they were there.  There were no traces of the old system (inside and out) and the areas were incredibly clean.  Nothing for me to do!  Again, it doesn’t get any easier than that.

Hats off to SGI Heating and Cooling. I would certainly recommend them to anyone needed their services.


We are very pleased with your sales team, installation and the Generac itself. When the county inspector came to see that it was installed properly he asked us who did the installation. We told him SGI and he complimented your company.  He said, “I should have known!  They always do an excellent job!

 Bottom line, if you are on the fence about which company to pick for your HVAC project (like I was), go with SGI through Home Depot. There were several issues that needed to be addressed in order to move forward with my central air installation project. These guys addressed EVERY SINGLE ONE OF THEM without price gouging or upselling or making me feel like they had better things to do. They respected our house and were mindful of the pet cat. The project was completed without any unnecessary delay. AND THE CUSTOMER SERVICE WAS ABSOLUTELY PROFESSIONAL AND OUTSTANDING. You would expect to hear a group of men cursing and carrying on at the job site. They guys did not. I remember the house being quiet because the electricity was off. I could overhear some interesting and entertaining conversations but nothing that would be considered rude, crude, disrespectful, or crass in any way. I wish that I could hire this SAME COMPANY to take care of our other upcoming projects, but unfortunately, they don’t do concrete, doors, landscaping, stairs, or kitchen remodeling.

I highly recommend them, and I am lucky to have had them in our home.

I wish every contractor we hire would be as quick and precise as the folks at SGI. They installed 2 furnaces, 2 AC, ductwork, and a water heater and anything we asked for was just, well, DONE! No question, no wait, no us figuring it all out by ourselves to get what we needed, no mistakes or worry – just done and done right. So easy to work with, so professional and enthusiastic about what they do. You’d think this was a family business they wa you’re cared for as a customer. HVAC can be scary, you worry it’s going to take a long time to get in, that something will go wrong etc but everything was smooth as butter. SGI contractors that did our work were: Darin Josh Spencer Todd John Matt All were just amazing. When they were in the middle of finishing up the job. we realized we needed a new water heater – and that water heater was installed promptly the next morning! It’s like you just give the genie your wish and they make it happen lol. We moved into a new large house and were out of our element and it needed so much work but the team at SGI made it a breeze and it was worth every penny. They also take the time to explain their recommendations so that you understand it. The HVAC was the least stressful part of our reno. Thanks guys.
