terrible customer service and if you have a fuel oil furnace, don't use them. They are not knowledgeable about these furnaces and the manager only is concerned with money, not customer satisfaction. read more

DTE shut off my gas and advised me to call a furnace company. I called Geo Furnace. They came right out to my rescue! They replaced 2 outdated valves that were leaking. Thank God for Their prompt response!!! All is working properly now. read more

My home is 100 years old and consists of the original farm house with several additions. There are several different roof pitches and a section with a minimal pitch. I began with insulation deficiencies, ice dams and an uninsulated crawlspace. Working with Geofurnace as my budget allowed they corrected these items over time. Each time they evaluated my needs; proposed a solution and carried out the repairs. They did the work for the agree-upon price, worked within the time schedule and left no mess behind! Thank you Geofurnace! read more

January 2019 I had some glitches with my furnace. I talked with my friend Peter (of 28 years), at Geo Furnace and he set me up with an appt for the next day. The very sweet Chelsea called that same day and said they had an opening for that afternoon. It was perfect. They sent out Kyle who was equally perfect. He was a true gentleman. Took his shoes off at the door, was very polite and informative as to what he was doing. I enjoyed my conversation about my 18 year old furnace with him. I am a "do-it-yourselfer" and he even taught me a thing or two. From now on I will only use Geo Furnace and I will recommend Kyle to anyone who asks. Thank you Peter for the recommendation. You will remain my forever friend. read more

Called GeoFurnace to set up a service call for our Water Furnace unit which was showing a red indicator light indicating a problem with a drain problem with the furnace. Service technician Shaun Howell arrive in a timely manner to service the unit. He was knowledgeable about the unit and was proficient in making the repairs that were needed to get us up and running again. I asked him several questions regarding the electrical power requirements for the furnace pertaining to the startup amperage draw. Shaun described an add-on, electrical device called Intelli-start that would increase the startup time from instantly to around a 10 second startup time which would drop the startup amperage draw requirements of around 88 amps. to a substantial lower startup amperage draw. Thus, saving some money on the old electric bill. I sounded like a good idea to me so, I ordered one and scheduled an appointment time for the installation. I'm planning to install a backup generator soon and the Intelli-start unit should help the generator to supply backup power to the furnace during power outages. read more

Knowledgeable efficient and dependable staff They even called me a few weeks later to make sure I was satisfied! Who does that anymore?

I would get a second and third opinion after using this company. Their diagnosis differed from three other companies I used, and what they diagnosed was going to be thousands and thousands to fix. The second company I had come take a look fixed it for $300. Geothermal unit is still working like a charm no thanks to this company. read more

We have a newer home with different pitches and have ice dam issues. We had to have something done and were told by roofing company that it was an insulation issue. I was very impressed with Jan (pronounced "Yawn" )who came out and spent about 4 hours looking at our home and attic and doing testing of various types. A few days later, we met with him again and he very thoroughly explained all that he found and why it might be the cause of our issues. While we felt the price was very high, we felt comfortable with all that he indicated they needed to do. Tom and Kirby were the two that came to do the work and they were very professional and got down to business. We knew the first day that they would likely have to cut out a portion of our cathedral ceiling to access the scissor trusses ends to insulate, and they did so it required a large section to be redone. The company they suggested and gave us a bid was 4 times higher than what we had it done for locally. This caused a delay in them coming back to finish blowing in insulation as the drywall needed to be up first. Of course we won't know until winter if it worked or not, but I am trusting that it will at least help a great deal. I wish we would have had two bids to compare, but we just felt comfortable with Jan and went with it. read more
