Recent Testimonial

I write this letter in recommending Greg Bruyere and his firm ‘Tristate Mechanical Services Inc.’ as a Heating and Cooling General Contractor. They undertook the installation of the HVAC system in our recently rehabilitated Church building; which is the new home for our Church. I can recommend Tristate highly and without reservation. Throughout the process, Greg was focused and professional. He was accurate in his initial assessment of the scale and cost of our project. He chose and managed his team well. I think (and so do many others in our congregation) that we have a wonderful outcome.
