What our customer are saying...

RJ B

Our A/C was 30 years old. T-Mark answered my call right away and came out the next day, replaced the Furnace and A/C. Crew was professional and seemed to know what they were doing. Seemed to get everything done without any hiccups or problems. Took time to go through everything with me. Very happy customer.

Bud Shalkowski

Gary and John were awesome. Helped fix a collapsed cast iron pipe situation to entire new pvc system in the basement and sump pump as well… they were unbelievably helpful and I am appreciative of everything they did.

Garrett Moffett

Had a leak in my water heater, I called many places and they were the first to come out. Fixed quickly and had no issues since.

Patrick Ellis

The technician, Mike, that came to our house to fix our a/c on an extremely hot summer day, was very professional, friendly, and knowledgeable. He had my air conditioner up and running like new in a very fast time. Thank you. I recommend this company to anyone and will be using in the future. Thank you Mike and T-Mark!

Rachael S

We had a great experience with Cody and Matt! They were very professional and knowledgeable. Our home was kept clean for the entire week they were there- and it was a messy job. Highly recommend!

Michelle Wing

I have had a nightmare of a time with the plumbing in the house I moved into a year ago. T Mark sent Seth out quickly, he was fast, professional, explained everything in detail, and was very understanding when I was very stressed. It’s very easy and efficient to schedule, company is great with communication, it was refreshing to be treated respectfully, would absolutely recommend and will use in the future.

Tiffany Quiles

Called and got a response back right away and got an appointment scheduled. Logan was very professional and got my heat back up and working in no time! Great service thank you so much!

John Chmarney

T-Mark did a excellent job replacing my water heater. Very professional all the way from the job quote through the timely, well done installation. GOOD JOB T-MARK.

Michele M

T-Mark installed my air conditioning unit 4 years ago. Very pleased with their work. I recently had them out to do a look and tune up on my unit. Everything from scheduling an appointment, to the actual service being performed was top notch. “Big Mike” came out for the service and he was absolutely wonderful. On time, very friendly. Took the time to answer all my questions. I hope nothing ever breaks and I need service, but if I do T-Mark will be my first call. Highly recommend!

Edward H

Had to have a sewer line and water service line replaced. The work was excellent, only took the two men 5 hrs and the price was very reasonable. Will definitely use this company again

Derek and his team were prompt, professional, accommodating, friendly, efficient and tidy.

Today, my new A/C and furnace installation was flawless. They’re my first and only call because they’ve earned my business, over and over.

Mike Bluff did an amazing job. He was highly professional, very friendly and super knowledgeable. He took extra time to be sure everything was installed properly and explained everything in detail. Truly grateful!

JEANINE SONIER

Kevin and Bryan did an awesome job installing my air handler HVAC system and HWT. They were professional friendly and knowledgeable. Ian who sold me the system was friendly and knowledgeable and knew about all the rebates and incentives available saving me thousands. T-Mark of West Seneca hands down is the best for HVAC/Plumbing service. I highly recommend them.

Jon Stachura was totally professional, respectful and congenial. He was actually available two hours earlier than expected. He quickly diagnosed the leak problem and offered best and worst case solutions for repair. Jon was mindful of the customers property. While he was initially expected to arrive between 12 & 2, he actually completed the job by 12:15pm. The job was not simple. It involved Jon opening a wall and removing a 125 year old section of iron plumbing stack and replacing with pvc pipe. Very pleased with his work. Thank you Jon and TMark!!!

Stacey Bubis

Ryan was professional yet down to earth and very informative and helpful.
We use TMark for all our plumbing and heating A +

Nicole Marie

Had an issue with toilet not flushing, so I called before business hours. T-Mark got back to be very quickly and had someone out less than 2 hours. The technician I had was Brian, and he was great. Let me watch the whole process of snaking the sewer line, and explained everything thoroughly. Very friendly, and overall I’m very happy it’s all fixed. Thank you!

Charles C

I highly recommend T-Mark for all your furnace and central air conditioner tune-ups and repairs. The office staff is wonderful, their prices are reasonable and their technicians are very professional and knowledgeable.

Excellent job! Easy to schedule, on time, professional, and fixed the problem.

Charles Dean

Brian Borkowski did a great job snaking the drain pipe to the bubler. He did a fine job explaining what he was doing and the condition of the drain system.
I’ve always been satisfied with T-Mark plumbing.
