Tri State Mechanical Services Inc

Very responsive! They provided service over a very cold holiday weekend. They worked efficiently and were able to restore our heating reliably in a timely manner. One of the few companies that provides reliable and accountable 24/7 emergency service!

Absolutely terrible company.
Never returns calls.
Amateur work at best that immediately stops working.
Random invoices for work that was never actually done.

And just when you think it can’t get any worse, the office manager is PRETENDING to be a NAVY SEAL.

Absolutely do not support this company.

Their service is very professional their crew, very kind ,courteous professional very diligent getting the job done, getting job done correctly and on budget, leaving the place clean after they finish their work. They did such a great job I felt compelled to feed them lunch one day and cooked up a whole bunch of slabs of ribs and fent all five of the people that were here. This was prior to us opening the 31st of May 2022, I have used their services to maintain some of our cooling equipment and they're always on budget and always on time.

We are very happy with the 2021 expansion at Pad Thai STL. Thanks for all the hard work Greg and your awesome team at Tri State Mechanical Services Inc. Fresh new look is Amazing - Thank You!

Every time we have done business with Tri-State-state it has been an overwhelmingly positive experience. Everyone on their team is super professional and their work is the same. We recently installed a hood and makeup air unit at Gallagher’s restaurant in Waterloo Illinois and we will certainly call them again for our next project.

We use Tri State Mechanical for our freezer and A/C needs. They are terrific!! We receive excellent customer service!

We know we can rely on him to bring skill and expertise every time he's here!! All around a fantastic company to work with!

Fast and professional residential unit! Took time to explain every thing about the new unit and did the little touches on finished job to make it look like it should. In addition, took time to do great cleanup so looked like they were never there.

I use Tri-State for all my HVAC needs. They are quick to respond to your needs. After calling Tri-state for a HVAC concern, they sent out their service tech Lonnie the next day. Lonnie was professional, knowledgeable. He was quick to discover the problem and repair the situation. Avoiding a potential house fire. Thank you to Greg at Tri-state and his employees.

We used Tri-State for a custom build and really enjoyed working with Greg throughout the entire process. He was knowledgeable, easy going, and quick to respond. Even after the process was complete he was available for any questions we had. Would definitely recommend.

Tri-State Mechanical is a great company to work with. They are a great partner. Our Company GT Ventures has had nothing but great interactions with them. Greg has been super responsive and finishes projects on or before the deadline. They are great in all of there fields from AC/heating, to installing hood systems, and even fabrication.
