Service & Repair

Serving you is the heart of our business. That’s why we answer the phone with a live person and have a Service Technician available 24 hours per day, 365 days per year.

Our radio dispatched trucks have thousands of dollars of parts in order for us to be able to repair your system as quickly and efficiently as possible. We have all types of regular and programmable thermostats, and even wireless thermostats that can be controlled over the internet.

We have trucks on the street throughout the metropolitan St. Louis area: from Troy, Missouri to Troy, Illinois and everywhere in between. That allows us to provide service to you quickly and in the time frame we commit to you. No other heating and cooling contractor offers the same prompt, courteous service that has made us the St. Louis area leader in HVAC services for over 125 years.

All of our technicians have completed a rigorous training program, have received factory instruction, and participate in our company-wide drug-testing program. All of our technicians attend Continuing Education classes in order to make sure that they are current with all of the new technologies that are coming forward in furnaces, air conditioners, home humidifiers systems and air filtration systems.

We believe very strongly in NATE – North American Technician Excellence – and have NATE Certified Technicians, meaning they’ve passed rigorous tests from our industry’s leading testing organization.

By the way, Welsh just installed a new system (furnace and a/c) in my father’s town house in Eureka. His a/c went out during the height of the August heat wave. Denny Turlin was our sales rep. As always, we got great service from Denny and your company!

We have used Welsch for over 30 years and have never had any problems. I recommend them highly. Very fair, prompt, friendly people and competitively priced.
