Andy is the best! So friendly, very thorough and explains everything in a way that is understandable for someone not in his field. Thanks for all of your help. We lost our water heater in the floods and they installed a reciprocating device, removed the water softener and converted our system to a tankless system.

Ron was efficient, friendly and gave me confidence that he knew what he was doing. He also gave guidance in next steps for a long term solution. Thank you, Ron, for getting my hydronic system drained, cracked radiator removed / blinded off and the system back up and running so that I could have heat in my home again.

Technician showed up when promised and diagnosed our problem promptly. Pointed out a couple other issues that may need addressing. The work has yet to be completed so will comment on the quality of the work when completed.
Edit! Our work was completed today by Andy. He did a great job replacing a nasty section of very old pipe.
Very neat and quality work. He cleaned up the area better than we would have expected. Very congenial and prompt. This was our first experience with this company and would not hesitate to use them again. We would highly recommend.

Kevin P was very courteous, friendly and professional. He cleaned and repaired my furnace, and installed a new thermostat per my request. He took the time to show me how to use the new thermostat, explained its functions and answered all of my questions concerning additional maintenance. Price was very fair and will use The Thielmann Group again in the spring for AC.
