I would like to thank you for taking the time to stop at our website. Please take a moment to read about the history of our company and what we stand for since the beginning.

Since 1989, Tristate Mechanical Services has carried on a tradition of impeccable service. Influenced by past employment practices from prior experience with other contractors, it was finally time to create a Quality Service Company with Integrity to make a positive impression in the HVAC and Refrigeration Service Industry.

In 1992 our first full time employee was hired as we had finally earned a customer base of long term repeated business. Since then Tristate has grown into a family business with Factory Trained Professionals and personnel which we consider to be the best part of what we offer.

We proudly serve the St. Louis and Metro areas including Central Missouri and Southern Illinois with the highest expectations of our industry. We always provide the Quality of our workmanship everyday as we continue to build a long term relationship with our clients.

For Dependable Service, Quality Installation and 1st rate Customer Solutions in HVAC, Refrigeration and Commercial Kitchen equipment we’re always there when you need us.

We have 24 Hour Emergency Service available with an extensive parts stock for all Commercial and Residential equipment old and new. If we don’t have it we’ll find it.

“I thank the Lord for helping in our Success and Knowledge in performing the services for the people we have the pleasure to do business with every day. We are greatly Blessed and stand behind it 100%”

Give us a call. You’ll be glad you did.
