HVAC reviews in Sycamore, Illinois

Very knowledgeable

Great company!! Very trustworthy and reliable.

Thanks to the furnace guy. I avoided even more cost in repairs.

Knowledgeable and Service Focused.

They did a nice job. Mark is very personable and committed to getting the job done right.

Super great guy! Stopped to help me with my car broken down on the side of the road with his work truck, I’m sure he had some important jobs to get to or would have rather gone home, that shows a lot about a person

I couldn't be more pleased with the professional service I received. Top notch service all the way around I would highly highly recommend Mark for even the smallest of problems to a whole new furnace like I needed 5 stars here and thank you again Mark for the no need to worry I got you attitude your the best!!

Quick response to phone call, showed up same day, diagnosed problem immediately and problem was fixed right away, fair pricing. Friendly service.

Mark and Dennis from the Furnace Guy highly recommend. They put in state of the art system for me. Quality work and fair price.

This guy was great! Very knowledgeable and helpful. The previous owner of my house thought he was a master of all trades except he wasn’t even a journeyman and I guess he had a one time replaced the furnace, and of course he did a hack job. Well this guy retired the furnace correctly and got my unit up and running!!! Thank you, thank you, thank you!!! You guys are all aces!

I’m sitting in comfortable air conditioning thanks to Mark.
I had an appointment for Thursday 5/12/22.
I called Mark To see if he could come before the heat started, and he was here yesterday (while he was busy as all heck) 5/10/22 and hooked up the AC. I couldn’t be more pleased.
Thanks Again for that, Mark. 👍🏼 👊🏼

Very knowledgeable and honest. Mark goes the extra mile.

Prompt, honest and thorough. No way am I ever calling a different company.

I love using The Furnace Guy. Mark is knowledgeable, friendly, honest, and reliable. His knowledge saved me from having to replace my entire furnace (as I was told to do by another place). He's my go-to guy. Thanks!

I called Mark because my furnace had stopped working and he said he would be out after he was done with his other appointment. I was just going to make an appointment for my next day off but he insisted coming out. He showed up a little late but it's not a big deal. I figured something extra needed to be done with the other job and he called to let me know he was on his way and when he arrived so I wasn't guessing. He had my furnace up and running in 2 hours. He also let me know how old the furnace was (I had moved into my house recently) and how long furnaces typically lasted. He never once made me feel uncomfortable or stupid for asking questions. Super professional. Will be calling The furnace guy for future repairs and/or replacements!

We were considering replacing out furnace since are old one is getting a bit old. Mark come out to the house to give an estimate. In the end we are going to hold off on making a changeright now. That said Mark was great. He is extremely professional and took the time to explain our options and give his recommendations. When we are ready I won't hesitate to call Mark to do the installation.

Showed up same day I called which was Saturday afternoon. Got a very reasonable quote and offered space heaters. He started installing monday and I had great heat. Would very much recommend him for furnace work.

Mark worked through the night to install our new furnace when it went out before our scheduled install date in the cold of winter. Since, he's put in our new A/C and thermostat and it all works like a dream!

Mark and his team are great to work with. Always makes time for us when his services are needed. Very professional and does great work.

Heater had issued & I called one of the those mainstream larger companies around 3pm who I will not name. Their first response was sir it's almost 4pm my guys are on overtime, and we can it schedule 3 days from now... rude A.F. Temparture was in the negative numbers l just hung up. After googling I found Mark's team thank God I did.. His first response was what is the issue & where u located. They got me a heat exchanger and quickly got it replaced & worked till 1am & which I was fine with because they had to go out of their way to get one. What an amazing team they did an amazing job. The only thing I'm really worried about is that I hope Mark is not going to be retiring anytime soon. Luckily he appears to be a young guy so I hope to do business with him in the future when it's time to replace my heater. Mark I hope 🙏 we will have ur company forever cause ur quality and service is second to none. No one else even comes close. I hope to be sending everyone I hear needing work ur way. You guys are amazing 👏 and are truly the best in ur trade, God bless... Shoutout to Dennis and Danny as well amazing workers👍 A+++

After having a blower motor issuer in my 31 year old furnace, Mark somehow got it to work temporarily until I could come up with the money for a new furnace. Him and his apprentice installed a new unit two weeks later. Overall experience was great and I’ll definitely be calling The Furnace Guy next time I’m in need.
