Outstanding work from start to finish. Would highly recommend.

We are 100% pleased with the job that Teutonic did for us! We had both our furnace and our air conditioning unit replaced and not only did they give us the best price, they also gave the best price to three or four of our friends, who also had their furnaces and air conditioning units replaced. The employees were respectful, clean, and could not have been nicer . Jens explained everything that was being done, and before he left gave me a tutorial on the new thermostat. Finally, every single thing that they touched was cleaned up. There were cloths protecting the steps, everything was swept up afterwards, all of the boxes were broken down and disposed of offsite, in fact, there was no evidence at all that they had even been here. I would recommend Jens and his crew 100%!

Irv is fantastic, very professional and knowledgeable. Always on time and this is a company you can trust in. I highly recommend.

I highly recommend Jens and Teutonic Temperature Control for any HVAC service needed. Jens and his knowledgeable team replaced my 25 old furnace and Aprilaire humidifier this past Halloween. From my initial call to the date of the new equipment installation Jens responded quickly and confidently to every question I had in what could have been a stressful home improvement project. Teutonic was at my home exactly when they said they would be on the day of installation and after a full days work I now have exactly what we needed for our home with several quality equipment upgrades I chose for this installation. I can't imagine this could have gone any better. I will be scheduling my annual maintenance services through Teutonic Temperature Control to keep me worry free!! Thank you TTC.

Jens is great. He diagnosed and corrected a problem with my a/c that two other companies failed to do. I wish i had called him first. Would have saved me time and money. Jens is very professional and can explain the problem in non-technical terms that makes it easy to understand. TTC is now my go-to company for furnace and a/c problems. Update 9/9/24 Jens and team installed a new furnace and a/c system for me. Everything, from the price to the level of service, was 100% awesome. I recommend TTC to everyone i can. Everyone always thanks me afterwards. Professional. Honest. Personable. Great communication from start to finish. I can’t say enough good things about TTC!

TTC is arguably the best home Improvement company I've dealt with. The dedication and craftsmanship is second to none. Jens (Yens) and his staff were pleasant and all business. The job was extensive. Heater, AC, hot water heater, all new duct work including dryer ducting. Beautiful and solid installation. No average "Big Box Store" feel here. It was personal. If you're looking for "old school" craftsmanship and professionalism, TTC is definately worth strong consideration.

Great service, fair pricing, complete showed true professionalism. I strongly recommend using them

Excellent customer service

TTC did a great job as always. I appreciate their honesty with what needs to be done and the hard work of Chris and Irv to get it done.

Overall, amazing experience! Stresses when my heater and then AC decided they quit!!! TTC made it easy for me. Larry was super professional with scheduling and paperwork. Irv had his team in the field replacing our units while we were out of town so even in the heat of summer when everything fails we came home to a cool house. Great job TTC!

I highly recommend Teutonic. The men are all professionals and very knowledgeable. We had our entire unit replaced and I feel like they left the area cleaner than when they started. I also appreciate how friendly they all were. My 2 year old had so much fun watching and playing with them that he cried when they left. Very price competitive too! We even signed up for their maintenance program that was 3 times cheaper than the other company I was using.

After speaking with several other well know companies in the Chicagoland area, I chose to go with Teutonic after meeting Jens through a referral. He was the first person to actually confirm that I needed to replace my existing AC unit/thermostat, walked me through what my options were, costs associated etc. without pushing me to make any quick decisions on the spot. This ultimately made me feel more comfortable with not only the price but also knowing that he personally would be involved during the replacement process. Everything turned out great! He and the crew were extremely professional and respectful while I worked from home and I now have a new AC and thermostat thanks to them. Will be recommending Teutonic to everyone.

TTC was great. AC wasn't cooling house and Jens came out very timely. Although it ended up just needing a good push on the breaker, he still performed a full maintenance on the outdoor unit and taught me some stuff as a newer homeowner that I’ll certainly use in the future. Our unit is old and likely needs to be replaced but he did not aggressively push us to get a quote or try and be a salesman. Very knowledgable.

Jens and his team were amazing! They were knowledgeable, respectful, and did great work.

They were great

TTC accommodates us when our furnace stopped working on a cold winter day. They sought a repair and found a part but once installed they realized the only solution was a new furnace. They did not charge us for the part and worked us into the schedule to install a new furnace. The workmanship was excellent. The communication was superb. And our new furnace is whisper quiet. I highly recommend TTC.

Professional. Super Knowledgeable. Super Accommodating.

TTC was quick to respond and reasonably priced. They removed our old and stalled a new Carrier furnace and a/c unit in 1 day. And they left my house clean. I highly recommend the company with a special thanks to Jens and Chris. They are a great team.

Easy to work with and installed our new furnace with no issues!

Highly recommended. I have used Teutonic for a couple of years now. I like knowing who is doing the work. Ive had too many previous experiences with work being subcontracted. Knowledgeable and personable- always willing to answer my many questions. I have used Teutonic for maintenance, repairs and most recently a new heating, cooling and heat pump system.
