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.

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.

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.

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.

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.

5 star rating! Irv was Awsome. He answered all my questions with easy. Before he was able to come out to look at my furnace he gave me some things to check over the phone. A lot of companies wont do that before they even come by. He was very helpful with everything. Him and the guys on installation day were polite very respectful of the house and us. They came and installed no problems and they were very clean and made sure it was clean after they were done. I would recommend this company to anyone looking for some work done. They did a phenomenal job.

Jens was super helpful and professional. I would highly recommend Teutonic Temp Control for heating and AC needs. He explained everything and was very thorough.

Superlative service! Irv has been providing my HVAC servicing for over 25 years. I can always depend on him for trusted and highly professional state of the art service and advice. Last week, Irv, Chris, and John replaced my HVAC system in less than a day and I could not be happier with their work. Efficient and excellent craftsmanship and problem solving. And Larry, who schedules appointments, always makes it easy. TTC is top notch.
