- CBCarolin Bush3 days ago5.0We are thoroughly impressed with their installation team and sales. From the start, Steve (sales) was easy to talk to and answered all of our questions regarding installing a mini-split. The installation team was also super courteous and cleaned up after themselves. They wore shoe covers too! Thank you Steve, Benjamin, Keegan and crew. Professionals from start to finish. A+
- MSMike Strege4 days ago5.0Dan from Thielmann installed a new 40 gallon hot water heater and also installed an outdoor faucet in my backyard. He did an outstanding job, from mounting the faucet outside, hooking the water upin the basement, to the water heater installation. Everything thing was done to highest of standards at a reasonable price. I will not hesitate to call them again for my plumbing needs. Thank you Dan and Thielmann heating, cooling &plumbing.

- KKKyra KnineAug 19, 20265.0Brandon and his team were efficient, friendly, punctual and professional. We had a 10KW Generac generator installed because our electric went out 8 times since we’ve owned our home in the past year. We were without heat and electricity for a couple days in January. We are looking forward to having peace of mind when it happens again.
