  Nick came in tuned our furnace and helped us enroll in a long-term maintenance program. He explained everything clearly and we pleased with his work and he explained the long-term plan clearly. We were impressed with his professional approach to his profession. Thanks, Nick. Bill Elliottp

  Andy & Jim were great and extremely helpful when our water heater flooded our basement during the holidays. We ended up paying ~$2500 for a new 50 gal water heater + installation/removal and they were able to get it in within 24 hrs of us calling. Both Andy and Jim were able and wiling to answer all of my questions, I will for sure be going back to them again!

  Ben and Jack from Thielman Heating and Cooling installed our new furnace today. They did a first class job and were very pleasant and attentive to all the fine details. I hope this one lasts longer than the last furnace, I only got 21years out of that one. Doesn’t anyone build stuff to last anymore? 😭

  Kyle L. Came to do a plumbing inspection that is free with your membership with Thielmann (which also includes furnace inspections twice a year as well). Kyle took his time inspecting and providing feedback on our Iron Curtain that needs replacing in the future. He did a water test and looked over all of our plumbing. He provided an estimate to replace our iron curtain as well. He was super friendly, professional, and came in the time slot as intended! I highly recommend Thielmann for all your heating, cooling, and plumbing needs!

  Thielmann: I'll try to give a brief background. The furnace (unit also has AC component) in my condo was having white smoke/steam come out of the external vent during some of the extremely cold weather we were having. Even though my furnace was not making any unusual noises, smells, or setting off my carbon monoxide detector, I was still concerned as no other condos in my building or nearby buildings were having the smoke/steam. The employee that initially inspected by furnace (Carlos?) informed me that the heat exchange was clogged and would require me to repair the furnace or purchase a whole new unit (I opted for a whole new unit based on its age). Carlos gave me the impression there was no rush and that it was not something that necessarily needed to be done immediately. When the second employee (Dave?) came later that day to take measurements and verify the replacement unit needed, he made it seem almost emergent and began to wonder aloud if he needed to shut my furnace off that day. The stark contrast between the two was alarming and created a bit of a trust issue on who to believe. Carlos seemed a little green and Dave seemed like more of a veteran. Dave eventually determined it did not need to be shut off as no carbon monoxide was entering my condo. The whole experience did create a bit of a panic for me though, so I quickly accepted the only available appointment within the following two weeks. It was convenient that they could get it replaced just five days later, but if it truly wasn't an emergency then I would have liked a little more time to verify I was getting the best price as it wasn't cheap (to give you an idea this is the largest purchase I’ve ever made behind my home, education, and car). They do offer payment plans that were easy to enroll in, one of which has 0% interest if paid off within a year. I’m not trying to throw anyone under the bus, but I can tell they really want an honest review as I’ve received multiple texts and emails asking to leave one. The crew that showed up on the morning of 12/24 to install the new unit were quick and efficient. They were respectful of my property and explained the new thermostat to me. All the employees were friendly, including the ones running the office over the phone (Micah?).
