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.

Tri-State Mechanical is a leader in mechanical contracting services for both commercial and industrial clients in the St. Louis area. We’re always searching for long term career minded HVAC and refrigeration personnel that share our vision of professional, cutting-edge service. Our employees can earn up to 60-100k+ yearly with an exceptional retirement package.
