Over a Century of Experience

We’ve had more than 100 years to apply our expertise to take care of your heating and cooling needs. Committed to quality customer care, our technicians continue to service the Greater St. Louis area just as current president George "Butch" Welsch’s great-grandfather did when he started The Welsch Furnace Company (now Welsch Heating and Cooling Company) in 1895. Welsch Heating and Cooling Company has received numerous awards and recognition for service excellence, civic responsibility and overall performance as a business leader in the St. Louis area and our commitment to our customers and to the community thrives today.

Just wanted to say thank you for the good service earlier today.  Phil came to our house this morning and got our A/C unit back up and running and the house is quite cool now.  Be sure to thank him for me – it’s nice to actually have to turn...
