Please take a moment to find out why Thielmann & Son is the top choice for furnace & air conditioner (HVAC) repair and heating installation service in Milwaukee, Menomonee Falls, New Berlin, Hartford, and Burlington.

 

Thank you too all!

From the salesmen to the installation crew. We were originally just going to replace the furnace. However,when it was discovered that we would need to replace the air conditioner as well, it took one call to our sales representative and they had the air conditioner and another service tech here within the hour to do the installation. All was completed in a day and the quality of the installation is top notch! We couldn't have been happier with the installation and product. We look forward to many years of comfort and energy savings. Thank you too all!

I recommend this quality product!

The salesman, Jason, is extremely knowledgeable, friendly and answered all of our questions. The lead-time to have the unit installed was not that long. The gentlemen that installed the unit were on time, friendly and professional. I would recommend this quality product and John Thielmann & Son's services to everyone.

Easier on my strained budget.

I am very happy with the new air conditioner that was installed at my home. I didn't realize just how loud and inefficient the old one was. I don't even know how old it was because it came with the house and I bought the house 15 years ago. It got so hot, so fast this year and I am glad that the service man took the time to explain what was wearing out on the old unit and how easy it could be to replace it with a new efficient model. The financing certainly made it easier on my strained budget.
