- MLMickey LeighFeb 14, 20265.0Our furnace went out overnight over the weekend during the deep freeze. Even though they could not get to us right away they made sure we were safe and had some heat source. The tech called and asked many questions to make sure he would have the right parts when he did get to us.
- SNSarah Holbert NickelDec 23, 20255.0Just in time for Christmas I needed to have my furnace replaced. Nick came out within an hour of calling for service, Steve followed about 45 minutes later and my new furnace was installed in 2 days. Ben did an awesome Job and was done way ahead of schedule. I couldn’t be more pleased with everyone I met. Great job guys!
- BBBrettDec 5, 20255.0A week and half after our yearly furnace tuneup we added an ultraviolet light to the HVAC system. They arrived on time and under an hour the job was completed. The installation went well. Was very pleased by the Ultraviolet light pre appointment to see if our HVAC was compatible. The explanation of the benefits was very thorough. I highly recommend Thielmann group for your residential needs.
