Furnace Installation & Replacement

If your furnace is 18-20 years old, it may be time for a replacement. Much like an old car, furnace repair costs tend to ramp up as a furnace nears the end of its lifespan. SGI can assess whether it is time for a replacement, and can show you all of the options available that best suit your situation. 

Our experienced technicians will ensure your new heating equipment is properly sized for your home, and that it is installed and serviced correctly.

Ductless Mini-Split Systems

Mini-split systems are great options for rooms that need heating/cooling, but lack the necessary ductwork. These units typically are capable of producing heating AND cooling, and multi-head configurations are available for homes that require mini-splits in multiple rooms.

If you use a boiler system as the primary heat source in your home, you need professionals who are knowledgeable about boilers and can make the best recommendations for you and your family. Contact us today if you are interested in boiler replacement and installation.

Heat Pumps

Heat pumps are an excellent alternative to traditional furnace systems for consumers that do not have sufficient access to propane or natural gas for heating. Unfortunately, heat pumps do not yet have the longevity of a contemporary hvac unit, and should be replaced every 10-15 years.

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!”
