Teutonic Temperature Control (TTC) provides excellent service and quality for all your heating, air conditioning, and ventilation needs for your home. Irv, Jens, Larry, and Chris our always friendly, dependable, and professional. Teutonic Temperature Control (TTC) replaced my old gas furnace and thermostat with a new Carrier's gas furnace and with a new Honeywell's thermostat in one day, at an reasonable price. Call Teutonic Temperature Control (TTC) for all your heating, air conditioning, and ventilation needs!

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.
