    WOW! That is all that needs to be said! I made a late evening call to Thielmann Heating, Cooling & Plumbing and within two hours, Nick was at my door. His positive attitude and knowledge were refreshing. He was eager to help, already had an idea of what might be our heating issue and went to work fixing the problem. He walked me through the process, step-by-step, and was patient explaining everything. He was in and out within an hour, and everything has worked well since. He suggested a few repairs, but he was not pushy in ordering additional parts or service. Excellent overall service!

    Lost heat on a sub zero weekend. Josh came out Sunday afternoon and got the furnace to limp home while he waited for a part for come in needed to finish the repair. When the part cam in he returned and installed to permanent fix. Josh was courteous, informative and efficient. Mind you, things were a bit pricey, but you get what you pay for. In this case, great service.

    I had an air conditioner and furnace put in back in 2020 and have them maintained routinely by Thielmann ever since. I have had nothing but a great experience with them. Very professional, and the technicians are knowledgeable and very courteous. I'll continue to use them and recommend them!

    I had the pleasure of getting to work with Gabriel when I needed to have the valve replaced on the water shut off to my house. I found Gabe to be very knowledgeable and efficient and appreciated that we walked me through what he was doing and what to expect. He got me fixed up in a jiffy and I was pleasantly shocked at how painless he made my stressful situation. The valve was replaced and works great! 10/10 would happily recommend/refer/reuse.
