Theilmann was the only company out of two others, that told us about code requirements for our furnace being on the first floor. They did an amazing job with it being in a small spot and loved our dogs!

The Thielman group is great. They were right on time, efficient and did an excellent job. My only struggle is with the digital thermostat. I wish I had a better understanding of programming it. I would highly recommend this company to anyone.

Our old furnace quit.  We called our old service provider, and the old furnace needed a very expensive replacement part.  He also tried to sell us equipment we did not need.  Being Costco members, I called Costco, and they forwarded our call to Thielmann.  Jason called, and gave us a price for a new furnace.  He came out the same day, and the price quoted over the phone was what we paid.  The installation was scheduled, and we are very happy with the equipment and the service.  Using Costco, we also got a nice rebate.  Thanks.

Salesman came in and looked at both the furnace and air conditioner and we agreed to get new ones.  He was very helpful.  Also, the guys that came in and installed both were polite and good at their installation.  Would recommend Thielmann.

Upon our first call to Theilmann Group with a furnace problem, thru to a new furnace and air conditioner. Everyone we encountered was professional and a pleasure to have in our home. This was not a planned purchase, but they made it as easy as possible. Highly recommend!!

Thielmann did a tremendous job replacing our Carrier furnace.  They worked with us to make sure we were able to get the right product and even worked with Carrier on the issues we were seeing on our old furnace as it was failing sooner than it should have.  The team was very professional and efficient.  Great experience.  We highly recommend them.

Stop shopping around and call Thielmann & Sons. Wayne, Chris and the team made it so easy, and made sure we understood all options and their impact to our home. Not only did they provide the information you look for in a home expert, but they gave us confidence that the price, timing, and install would go as planned, AND IT DID!

They won't upsell you if you don't need it, and if they urge you one way it's because is it's the best option for you.

Thanks to the whole team!
