Your Comfort Company
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.

I would like to again compliment one of your fine employees.  He comes two times a year and is always on time, I told him if he is early come anyway, so now he is a little early, great.  He is very efficient and I think does a good job,...

I have used Welsch Heating and Cooling for over 17 years. They are always responsive and very helpful!

Removed old equipment and installed new heating & air-conditioning system in our home. All work was completed in one day as promised, and performed in a very professional manner.
