Thielmann & Son Heating and Cooling

These guys were awesome. It was a 93 degree day and I was having a furnace installed (only in Wisconsin) they arrived on time, went right to work and I never seen them take a break. They worked for 8 hours explaining what and why they were doing making sure everything was working before they left. I have used them for 5 yrs now and highly recommend them to everyone. The service cannot be beat.

T & Son bid against 3 other contractors for our HVAC needs. Bid was thorough, detailed and very competitive. They also provided better rebate info than their competitors. New equipment works fine. They even came out free to tweek the furnace for better performance settings. We thought the A/C was noisier than our old unit. They came out and discovered a need for some vibration insulation on the tubing mounted to our basement ceiling joists.... no charge. Techs both knowledgeable and experienced.
