Quick Overview

This summary is generated from the verified data on this profile: services, service area, credentials, warranty terms and the company's Google review record.

T-Mark Plumbing, Heating & Cooling runs a 24-hour dispatch out of Buffalo's north side, covering plumbing, heating, cooling and electrical work under one company rather than separate trades. More than 25 years in business and a 4.9 average across 4,442 Google reviews back up the scale, and reviewers consistently name individual technicians, Zach Doel, Ian and Alex among them, for specific plumbing and HVAC jobs. The company is BBB accredited, carries Buffalo News Best of 716 recognition, and works as a Generac generator dealer, a real asset in a region prone to storm outages. Financing and a Home Team maintenance plan are advertised, though specific pricing is not published. One lower-rated review described a visually unappealing AC unit placement that required a manager to resolve, worth asking about directly.

Our Take on T-Mark Plumbing, Heating & Cooling - Buffalo

T-Mark's real advantage is breadth: one 24/7 dispatch covering plumbing, heating, cooling and electrical, backed by more than 4,400 Google reviews at a 4.9 average, and an office that replies to reviews by name. A recent, serious complaint about reversed venting on a tankless water heater install is worth taking seriously if you're booking gas appliance work; ask pointed questions about post-install inspection before you sign.

  • Gary Schmelzer1.0DO NOT USE THIS COMPANY! They installed a tankless water heater for me and 15 months later the unit shut down. For an emergency service they couldn’t come out for 4 days. Come to find out they reversed the intake/exhaust pipes so carbon monoxide flowed back into my house for 15 straight months. Could have killed my family. I complained and even though they admitted fault and fired the installer they refused to fully reimburse me for the other company’s service and also claimed the tankless water heater is sealed so it couldn’t leak out. I’m not an engineer but Last I checked bolts do not provide an air tight seal on anything. Worst part they’re getting away with negligence. Keep your family safe. Use someone elseSeptember 2026Google
  • Remo2.05 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 to happen the worker correctly diagnosed the issue and fixed it free of charge. I was very happy with this service, despite the initial misdiagnosis. This is what you hire HVAC contractors for - I do not have the expertise to know what is wrong and you hope who you hire does the right thing. For a hot water tank replacement, I previously had a chimney vented water heater and was given an option of a cheaper less efficient heater or a more efficient heater (>$1k more) when being sold a replacement. I incorrectly assumed that I would only be sold options that would make sense long term - the added efficiency saving more than the upfront install cost. After installation, I see that the installed model is a power vent model that is only slightly more efficient than the chimney vented model of the same type. Researching these models, they typically only get installed when a chimney vent is not possible. My chimney vent was and is working fine. Knowing the model details now that the unit was installed, I contacted T-Mark asking for some more details about the sales process before leaving a review: why the power vent was suggested as an option. After followup, I was contacted by the sales person who said he would send over some information about how the power vent model's added efficiency and cost savings. It is a few weeks later now with no additional response. By my calculations, unless the price of natural gas more than doubles or the tank lasts over 25 years there is no cost savings over the less efficient model. Unfortunately I will have to find a new plumber/HVAC maintenance team that has their sales process aligned with their customers' best interests.September 2026Google
  • Nicole5.0Riasad did a great job with the furnace tune up, he was very quick and informational. I let him know of the issue I was having, and he was able to identify the cause. The price was great and affordable as well. I would definitely use TMark againSeptember 2026Google

  • Rosie dee5.0Dylan was an absolute sweetheart! He was very nice & knowledgeable & most of all, honest. He eased my mind by letting me know that my house is not going to burn down anytime soon. (I lost my last house to a fire so I am very paranoid about that!) Thank you to T-Mark for the free inspection. Scott came over on Tues. He also was great. You are very lucky to have such wonderful gentlemen working for you! Sincerely, Rose D.September 2026Google

About T-Mark Plumbing, Heating & Cooling - Buffalo

T-Mark Plumbing, Heating & Cooling has worked out of its Englewood Avenue location on Buffalo's north side for more than 25 years, and the company now covers plumbing, heating, cooling and electrical work under one roof rather than as separate specialties. That range shows up directly in the reviews. Nicole credited technician Riasad with a quick, well-explained furnace tune-up, and Cheryl Brinson named technician Jay for diagnosing and resolving an electrical issue in a clear, professional visit.

Reviewers also describe a stable, reachable office: the company replies to nearly every Google review by name, thanking specific technicians and addressing complaints directly rather than leaving them unanswered. That pattern, technicians called out by name across plumbing, HVAC and electrical visits, points to a large crew rather than a rotating cast of subcontractors.

A serious complaint needs to be stated plainly. One reviewer, posted September 20, 2026, describes a tankless water heater T-Mark installed with its intake and exhaust pipes reversed, which the reviewer says allowed carbon monoxide to vent back into the house for roughly 15 months before the fault was caught. The reviewer states the company acknowledged the installer's error and dismissed that employee, but disputes how the company handled reimbursement for the safety issue afterward. A second recent reviewer, a five-year customer, separately describes being sold a more expensive water heater model on efficiency claims that did not hold up under their own research. Both are specific, checkable complaints rather than vague dissatisfaction, and anyone hiring T-Mark for gas appliance venting work should ask directly how the installation will be inspected and by whom.

The company posts 24-hour availability every day of the week, holds Buffalo News Best of 716 recognition across HVAC, plumbing and electrical categories, is BBB accredited, and works as a Generac generator dealer, useful in a region prone to storm-driven power outages. Financing and a Home Team maintenance plan are advertised, though specific plan pricing is not published.

Who this suits: a Buffalo homeowner who wants a single, always-open contractor for a heating, cooling, plumbing or electrical problem and values Generac generator support. Who might look elsewhere: anyone whose job involves gas-fired venting work, given the carbon monoxide complaint above, without first asking pointed questions about post-installation inspection.

Before booking, ask what a 2 a.m. dispatch actually costs versus a daytime appointment, request the specific NY licenses for the trade you need, and for any gas water heater or furnace venting work, ask directly what inspection or CO testing happens after installation and who performs it.
