Teutonic Temperature Control

Jun 2026

My water heater failed yesterday and Teutonic Temperature replaced it within 24 hours. I appreciated the quick turnaround because the water valve leading to my water heater wouldn't shut off and I had to turn off water to the whole house.

Chris and Johnny were very thorough and knowledgeable. In addition to swapping out my ancient water heater, they replaced the water valve, the gas valve, some piping, and a vent that was probably not up to code.

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!

Our air condition went out on Wednesday evening around 8pm, I sent an email to TTCS same night at at 7am on Thursday morning Jens called me back. He was in Elmhurst already and could stop by at 8am. By 9:30am Thursday morning we had cold air blowing in our bedroom again. One of the capacitors on the compressor had gone bad; Jens replaced it and went over both units to check for gas pressure. Perfect service at a fair price! ?
