Today, I met with Gabe from Thielmann regarding our plumbing needs. He was a fantastic representative. Extremely knowledgeable, articulate, and patient while addressing our questions. He listened to our concerns and desires without being pushy. It was a wonderful experience, and…

I had a furnace checkup today, and Nick Kastner from Thielmann Heating & Cooling arrived around 1:30 to inspect the furnace. Everything was in order, and we are set for the heating season. He spent about half an hour here.

Rich was excellent. The company is impressive and professional. Highly recommended! I was referred to this company by others, and I completely understand why they are held in such high regard.

Due to flooding, my hot water heater was damaged! I contacted Thielmann (since they were previously known as Ross, the service I used to rely on), and they came out to check on my pilot light issue. Unfortunately, the inch of water I had was just enough to short-circuit things. T…

CAUTION! Thielmann technician Jeremy "serviced" a boiler that was functioning perfectly on two occasions, and both times, he seemed to cause more harm. The first time, in 2023, he claimed it required a new valve (costing $588) -- which is now leaking and needs to be replaced agai…

Thank you for taking the time to share your feedback. We would like to clarify our perspective on this matter. According to our records, we performed boiler maintenance in 2022. At that time, it was clear that routine maintenance had not been conducted for quite some time. Follow…

The service was excellent. The installation was swift. They removed the old furnace and air conditioner without leaving any mess behind. They cleaned the entire area and more after the installation. Outstanding service.

Great service, top-notch equipment. Highly recommended. The heat pump operates quietly. It keeps my home cool during the summer and warm in the winter while also being environmentally friendly.
