- MSMartha Strom4 days ago5.0Have been using Theilmann for 3 yrs now for maintenance as well as any replacement needed. Great communication and fair pricing! Todd H was just here today and was very knowledgeable and willing to spend time answering my questions. Very satisfied customer!
- JSJoe Sannasardo5 days ago5.0Gabe did a great job changing out the anode rod on my hot water tank. The shop ordered the wrong rod, which was not what I was expecting, but Gabe made it work and explained all the steps of the installation as he went.
- SMScott Miller5 days ago5.0Dan E. did a great job replacing my 50 year old hose bibs to include anti freeze, anti siphon and new shut offs inside the house. Dan was professional and did the job right. I highly recommend Thielmann and Dan E. Thank you Scott Miller
- TDTim DuerrApr 2, 20265.0We again had a failure in the heating system. Scott M. Came out and with the team at Lennox and Thielmann they came up with the solution that the board in the new Lennox furnace was bad. So far all is good. Thank you again to Scoot M. From the the Thielmann for the repair. The weather has changed to cold and rainy so have a working heat system is important to us. Nobody likes failure in a new product that they purchase but if the Thielmann company comes out to resolve the problem that's all we can ask. Thank you, Tim D.
