Reviews for The Thielmann Group

Awesome service and job completion. Jake came right away and worked tirelessly to diagnose the issue. Found the issue, very informative, got the pets, installed. I was shocked at the cost in a good way. Thielmann is the BEST!!!!

We had problems with our home boiler system. I had Thielmann come in and quote me a new system. The person who came was extremely knowledgeable (Steve). After recovering from sticker shock we contracted them for the job. They were able to schedule us within a week. They were in and out in less than a day. Cleaned up everything. Installers were very professional. New system seems to be a winner. Office staff was pleasant too...as they took my $$...loll. Highly recommend!

Was able to come out same day to troubleshoot/fix a non working furnace. The tech was prompt, friendly and knowledgeable. Definitely would recommend them to anyone needing HVAC work & will use again in the future.
