They were very professional. Left the jobsite very clean. Explained the equipment quite well. Walked me through the several rebates. Overall, I cannot think of one bad thing about my experience. AG

Our family tried 4 other company’s in St. Louis to replace old boiler and three AC units for a 4,500 sq. ft. , 100 year old home. It was a VERY complex project involving a lot of thought and creativity. The project was also completed a week before its expected...

Welsch did a great job installing our outdoor a/c unit and replacing the coil. Quick, professional, polite and treated my fiancé with respect. Really appreciate the work they did.

Welsch Heating and Cooling came out fast (our old unit stopped on a Friday – our new one was in by Monday.) They were very responsive to our needs and very helpful during the installation and followed up to ensure we were happy with our service!

I was extremely impressed with the technician. He came and looked at my unit to see what they can do to make it work more efficiently. He also told me exactly when he was coming and he was fair in pricing. Very professional. I really appreciated him. I commend the servicemen...
