Teutonic Temperature Control is the absolute best! Jens is knowledgeable, friendly, punctual, honest, reliable, and truly cares about his customers. We have used TTC for years and have never had any issues or problems. I can't recommend Jens and his company enough.

The service was great, timely and professional .

We recently had the pleasure of working with IRV and team, and I can confidently say he is one of the most knowledgeable and skilled HVAC professionals I’ve encountered. From diagnosing the issue to providing a thorough and efficient solution, his expertise was evident every step of the way. IRV took the time to explain the problem and the best course of action, ensuring we understood what needed to be done. His attention to detail and commitment to quality work set him apart!! We are reallly pleased with the job done by Teutonics!

Irv has been fantastic, keeping us informed of all aspects of our project. We trust him, the best recommendation you can have .

I cannot recommend Teutonic enough! I had two different companies come and inspect what was wrong with my furnace and neither could diagnose anything. Then I was recommended Teutonic, and they identified the issue immediately, fixed it, and the furnace has never run so well. In addition to being more knowledgeable than any other I've worked with, Jens was also very friendly and took the time to answer all of my questions and made recommendations for the future. If you're reading this review, look now further and hire Teutonic!

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 replaced. 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%!

Outstanding work from start to finish. Would highly recommend.

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

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!

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.

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.

Tested and trusted, my heartfelt gratitude Mrs Sandra Billy for helping me to trade and yield in forex trading, I now believe that Forex is verisimilitude “Most of the important things in the world have been accomplished by people who have kept on trying when there seemed to be no hope at all.” I have been seeing lots of positive recommendations about Mrs Sandra Billy a qualified trader, finally decided to venture her platform which I invested just $2,700 and successfully earned $32,600 in just 7 days, wow!!! what a pleasant experience which was astonishing and surprising then I re-invested continuously.

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! Very knowledgeable, respectful and do great work.
