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.

TTC is outstanding. Our air conditioner needed to be replaced and Jens (the owner) was out the next day. We couldnt be happier with the work Jens and his team did. They are professional, friendly, and VERY price competitive. I highly recommend them. You will not be disappointed.

We use TTC for all of our HVAC needs. Last summer they replaced both of our central air units. This week our furnace went out and they had our furnace replaced within 2 days. Their prices are reasonable and Jens, the owner, is a great guy who is friendly and professional. I highly recommend Teutonic Temperature Control!

Jens installed a new furnace and an ecobee a couple of years ago. He came my way via a family friend and he has been the best. With the last attic freeze, my radiator pipes froze and burst. He came asap and stopped the leak. Exceptional service, dependable, honest and reasonable. Highly recommend!

Have been using this company for years for general maintenance. This year we had to replace the furnace and they were able to replace the furnace within a day of diagnosis of replacement.

Terrific experience with Teutonic Temperature Control. Had a UV filter system installed and HVAC + humidifier system checked/cleaned. Chris was very knowledgeable, thorough, and helpful, offering a lot of value-adds and critical fixes vs. inherited (and clearly visible) issues from prior homeowners/their HVAC service provider. Larry was very responsive, resourceful, and conscientious in scheduling and with follow-up questions. Glad to have discovered this small business and am definitely planning to use again!

Prompt, excellent installation. Jens coordinated installation while Chris and Orlando worked all day with great results. I will schedule yearly maintenance with TTC. I’m completely satisfied.

We recently purchased an older house that needed some updating including a new furnace, new ductwork and overall inspection. Teutonic we’re extremely helpful; they completed all the items listed and were also able to install a return air duct to improve overall airflow on the second floor. They were always professional and gave recommendations on improvements that could be made without ever pressuring us into getting things done. We were also happy with how efficient they were and the work areas were spotless when they left. We plan to use Teutonic for regular maintenance moving forward.
