Had the pleasure to have Colin from Thielmann group come for my furnace tune-up. He was very knowledgeable, professional, and most important friendly. He finished the job efficiently answered all of my questions and was truly pleasant to talk to. I highly recommend The Thielmann Group and specialy Colin Bollman for those who need furnace service.

Jake arrived within the window I was given. He was polite and knowledgeable and diagnosed the issue quickly. Before he left I had a quote for the repairs and he was able to call the office to send an additional employee who will give us a quote for replacing our furnace.

Benjamin Green and his crew replaced our furnace today. There guys are an outstanding professional crew. Benjamin clearly explained the processes. I have had great service and interactions with the local Thielmann management, support staff, and installers. I highly recommend you check them out if you need any heating or air conditioning service.

Shane did a great job for us. We appreciated his attention to detail, to the point where he knew we were burning candles by looking at the furnace filter. I replace my filter every 3 months and had just replaced it a few weeks ago, so wouldn’t have checked/ replaced it till February. But, when Shane checked, the filter was totally black, caused by the burning of candles. Something I wasn’t aware off. Thanks for the save, Shane!

Aaron was very clear when explaining the air duct cleaning process, noise level, time to completion, etc. When finished he even took the time to walk me through where he found the most buildup and he answered all of my questions. I have utilize Thielmann for both heating and cooling and have found them to be timely, always professional, efficient in clean up and install and very easy to work with.

Had a 25 year-old A.O. Smith water heater replaced by Thielmann Group. Able to come out to my home and replace old water heater within 24 hours. Eric and Branden did an awesome job. I was contacted early morning when they would arrive with the new unit. They prep my house to avoid any mess and cleanup was perfect. I have no complaints or concerns regarding their professional work. This is a trusted company that I’ve used for years for a furnace and air-conditioning replacement .

Thanks to Thielmann Group for the prompt and efficient service call that we received this past Friday. Josh Van Den Hout provided excellent customer service! He walked me through the steps of how to change the filter on our April Air system as I had issues with it after I thought I could change it. He was very respectful when I asked questions and made sure I understood how it worked and explained the entire Carrier Infinity System functions in a manner that I understood. I gained some extra knowledge about the system that will be helpful in the future. I also learned some safety information that I did not know. Josh made a suggestion about the new payment plan option that I signed up for. It will save money on future service. When he was finished with the job I felt better about the error I made, and I learned something. Plus, he cleaned up any mess that was made! I am a very satisfied Thielmann customer.

Benjamin Green did a great job installing my furnace and humidifier. Both guys were very proficient and were able to answer any questions I had. The work was done in a timely manner and was excellent. Jim Kurtz
