Trey and James were awesome. They explained everything each step of the way and extensively tested the system. The work area was left immaculate and the new system looks fantastic. Thanks for your hard work and knowledge of the system. Very happy with the whole installation process. Also a shout out to Matt for his guidance in choosing the best equipment for our situation.

My experience with TMS had some challenges, but I appreciate that they ultimately made things right. I ordered a specific kitchen sink and a smaller garbage disposal. On the first scheduled installation, the installers arrived without the sink. On the second visit, they again came without it and had to return to the warehouse to pick it up.

An apprentice handled the initial installation work. The wrong sink was installed, and the installation caused my countertop to lift about half an inch. To avoid an even longer wait, I agreed to keep the sink, and it was trimmed to make it appear like the correct fit. They ultimately had to hire a contractor to correct the issue.

Despite the frustrations along the way, everyone was very nice and they stuck with the job until everything was corrected and we were satisfied with the final result.

I had a fixture I needed changed out, but no electrician would touch it due to the height of my ceilings. Total Mechanical Systems did not bat an eye. They came in with scaffolding and took care of it. Jared and Dave were professional, efficient, clean, and respectful. They even offered suggestions that were practical. I would use them any time. The best experience I could have imagined. I would add several more stars if I could.

The pictures give perspective of the difficulty of the job, due to the 18 foot ceiling. Before and after photos.

I am writing to express my profound appreciation for the exceptional service provided by Gary at my home today.

From the moment that Gary arrived at my home he demonstrated an exemplary level of professionalism coupled with an incredibly approachable and pleasant demeanor, making every interaction remarkably effortless and comfortable.

Gary, was also extremely patient and took the time to meticulously answer all of my questions.

Furthermore, Gary proactively included me in every step of the service, fostering a sense of transparency and trust that is often rare to find.

This inclusive approach not only speaks volumes about his character but also highlights his superior customer care skills.

The thoughtful and clear communication Gary maintained throughout his work today significantly reduced any potential anxiety or stress I might have felt. Transforming what could have been a routine service into a genuinely positive experience.

Gary, is also an individual who clearly goes above and beyond the call of duty. Not just in his technical execution, but also in his ability to connect with and reassure customers.

If I were able to assign a rating beyond the highest possible, Gary would undoubtedly earn it without hesitation. As he is without question, an invaluable asset to your company, representing the very best in service excellence and customer satisfaction.

It should also be noted that Employees like Gary are instrumental in building strong client relationships and upholding the company's reputation for quality and care.

Thank you for employing such a dedicated and exemplary individual.

Sincerely,
Natalie Sapp

Many thanks to the team of Nick, Kyle, and Finn! They were polite, professional and friendly as they worked all day long to replace my boiler to bring heat back to my cold, cold house. I was impressed with how hard they worked and how focused they were as they removed my old boiler and installed the new one. I also appreciated their knowledge of my heating system and taking the time to explain the mechanics of it to me. I am extremely happy with the quality of their service and would highly recommend them.
