T-Mark Plumbing, Heating & Cooling- Buffalo

Dylan was fantastic. He was able to the work in a reasonable time, being very accommodating. He was faster and more efficient than other electricians in our area. In addition, Matt was also able to do a fantastic install with the plumbing lines to our new espresso system. Both T-Mark guys were fantastic. Highly recommend their professionalism.

Wow. Eventually they got the work done. I'm at 2 and a half months. I've already paid and I still can't get anyone to come finish the job. They put the wrong equipment in and then came to replace it. They have had 3 months to clean the ducts but that still has not happened. You can't just call and get it scheduled.… Read full review

I'm always extremely happy with the service I receive from T-Mark. Dylan, the electrician who was here today, was no exception. He was courteous and explained what was going to be done and what was done in a very clear manner. Two thumbs up for Dylan and T-Mark!

5 year customer of T-Mark. They replaced our furnace, AC, and most recently a hot water tank. We had minor issues in the past, the AC T-Mark installed was wired incorrectly. When called for a service T-Mark initially diagnosed as needing an expensive part and service. When the service/part replacement was supposed… Read full review

Young Dylan Weber was a professional accommodating pleasure. He was also patient and he provided necessary additional support for my pending project that was i limbo. What A Fantastic Guidance!

The Plumbers stopped by to help set up a new water system for me. This included setting up a complicated faucet and running new tubing. They were helpful and thoughtful during the entire process. They arrived early, were very professional, and very kind to my three large dogs in the home. 10/10 would recommend.

Ryan did great work relocating our gas line. Quick, clean and efficient. June 17, 2026 - Update - Don replaced a couple of external hose taps and was fast and friendly! Continued two thumbs up for T-Mark!!

Dylan did a great job installing/wiring a new electric oven hookup when we switched from gas to electric. He also was very informative when he explained how the new hookup worked in the electrical panel. He was very courteous and even took away packaging trash from our new oven! T-Mark as a whole provided a great… Read full review

Ben and Dylan did a great job on my full 200amp service replace and upgrade. I had water damage to my breaker box and they had to replace everything and bring me up to latest TOT Code. The work looked very clean and precise and they took the time to explain what they did and why and made sure I knew where cutoffs… Read full review

I used T-Mark to replace a pump for my utility sink and to install a water purification system. Every step of the process was highly professional, timely, seamless and friendly From the initial visit for an estimate, to scheduling the projects to be done, to having the work done, to billing and payment - the team… Read full review

I had a furnace/A/C install scheduled when I experienced a partial power outage the evening before. Alex K. came with the installers and solved my problem within minutes! The entire tech staff at T-Mark has been so good to me over the years that I've hired them, I can't say enough positive things about them. Their… Read full review

They guys showed up on time and first thing asked about our issues and needs Since our house was built in the 1800’s it was a bit more complicated compared to new house install Completed the installation ahead of schedule and cleaned up everything as it was before they arrived The new furnace works great and… Read full review

I have used T-Mark before and Derek has been our technician he is fabulous.

Dylan Weber came out and was an incredible help working with me in myself getting the lights needed so he was able to install them. He had another call and said he would be back and was after I made purchase of the new light fixtures. I only thought it was a wire short, but infact told me they were fixture issues in… Read full review

Ryan and Luke were very efficient, completed the job correctly, along with being very polite and courteous. I highly recommend TMark for your needs.

Andrew with TMark come to our home to install a new split unit. His whole crew was super professional and answered any questions we had. They encountered a few obstacles in our older home, but they were able to compete the job in a timely manner. I would highly recommend calling TMark for any home need.

VERY unprofessional. I have been waiting 3 months for a plumbing estimate. Followed up several times with still no response. I missed an entire construction season on building a new house due. To the incompetence/ laziness of this company.

I cannot speak more highly of the service we received installing a new General Generator. The team was professional, knowledgeable, worked extremely well together, organized, on time, and completed installation & cleanup beyond our expectations! The experience we had with T-Mark has restored our faith that there… Read full review

Once again, Gary Seitz did an excellent job at my house. He is always so kind, professional, and knowledgeable! He installed a new faucet on my kitchen sink. Thank you!!!

Our hot water tank started leaking. I called another place first (which I won't name) which was closer to my house. They couldn't get out to my house quickly and also seemed to not really know what was going on--- phone tag--- but the price they quoted over the phone for replacement was reasonable. I then called… Read full review

On Saturday Feb 26 our furnace quit. Temp was 12 outside at the time. We called several Heating companies and T-Mark was able to get a technician out in the afternoon. Logan found the problem (Failing blower motor) very quickly. Knowing that it was an old furnace and she would not have replacement parts she… Read full review

These guys are great. When my furnace suddenly went out they were responsive and got over right away. The furnace was ancient and I decided to have them replace it and they had one over and installed the next day and it's running great and just in time for these frigid few days we're having. I would absolutely… Read full review

What is the point of visiting people's homes if the first thing they do is tell me that I need an engineer to come and draw up a plan before your plumber can do anything. He didn't even try looking around the house to give me some idea. T- max technicians came and left in 5-10 min later.

Ryan’s company Tmark is great. Iv always used them and they have always been super responsive and on time and done great work. Very professional. I just used them to replace my hvac system and they came right out to look at my old furnace and sent someone to get an estimate and replace my old system. Ian was very… Read full review

Kevin was so accommodating and very straight forward, easy to understand, and nice. I would recommend him to anyone!

Great service, professional and efficient. They cleaned up after the install and were very communicative throughout the process. Highly recommend!

Very professional and nice. They do great work.

Professional and efficient service. TMARK plumber CJ solved my sewer drain issue in 30 minutes without any issues or hassles. HVAC technician David is awesome a true professional. TMark- a company that I've had the pleasure of working with in the past and will continue to use in the future.

New A/C install Lenny and Derek did a fantastic job. Showed up and got straight to work. Communicated well and walked me through everything they did when completed. Thank you.

Greg was extremely professional and genuinely a nice guy. Very trustworthy and fun to talk to. I couldn't be more pleased.

He troubleshooted the problem instantly and corrected it on the spot. I have used T Mark many times for furnace and air… Read full review

Fantastic service when I needed it immediately. Everything was explained in detail. Everyone I interacted with was on time, professional, courteous and went out of their way to explain everything and give me choices. This is my second time using them and it will not be my last.

Rich was very nice and was able to explain the different parts of the job in a way we can understand. We are looking forward to the work being done.

My mother Rose G. Had work done today by a man named Nick Smith. He was such a nice man to her. He let her know everything he was doing, he showed up on time. He did great work. This is a amazing company that I will use myself now for my plumbing needs. Thank you Nick for taking care of my mom.

Jim did a great job hooking up our kitchen sink drain and water supply. A little pricey but worth the time and aggravation of a diy.

Excellent service by Craig on sink and faucett install.

I renovated my kitchen and moved the location of my range, sink, and dishwasher. TMark gave me a quote for the work and the number didn't change. I had to delay the second appointment several times because of delays I ran into with the renovation and they were very understanding.
