HVAC reviews in Grand Island, New York

Great guys that do great work. Wouldn’t want anyone else.

Great professional company. They've been in the business 20+ years and really know their stuff. Installed all of our furnaces in a timely manner, and were great to work with. Definitely our Go-to's for commercial HVAC.

JM Mechanical installed the heating and cooling systems across seven new-build apartment buildings for us and handled the project exactly how it should be done. The work was well organized, professionally executed, and consistent across all buildings. The systems have since performed as expected. Definitely recommend JM Mechanical for your small or large commercial HVAC needs.

I can’t say enough good things about JM Mechanical. From start to finish, the experience was professional, smooth, and genuinely reassuring. It was exactly what you want when dealing with an HVAC issue.

Our furnace broke down at the worst possible time, and JM Mechanical responded quickly and professionally. Scheduling was easy, communication was clear, and they showed up exactly when they said they would. What really stood out, though, was James and how efficient and knowledgeable he was throughout the entire repair process.

James quickly diagnosed the problem, explained what was going on in a way that actually made sense, and got right to work. There was no wasted time, no upselling, and no guesswork. Just efficient, skilled troubleshooting and repair. It was obvious that he knew exactly what he was doing, and that level of confidence made a stressful situation much easier to deal with.

The repair itself was completed faster than I expected, and James made sure everything was working perfectly before he left. He also took the time to answer my questions and offer helpful tips to prevent future issues, which I really appreciated. It’s rare to find someone who combines technical expertise with great customer service, but James absolutely delivered on both.

Overall, JM Mechanical exceeded my expectations in every way. They’re reliable, honest, and clearly take pride in their work. If you’re looking for an HVAC company you can trust, especially when something goes wrong unexpectedly—I highly recommend JM Mechanical. I won’t hesitate to call them again in the future.

As a commercial building owner, I’ve worked with several HVAC contractors over the years, and JM Mechanical of WNY truly stands out. They recently installed a new rooftop unit for my building, and the entire process was handled professionally from start to finish.

Their team was knowledgeable, punctual, and communicated clearly throughout the project. The installation was done efficiently, safely, and with great attention to detail. They coordinated everything smoothly and left the site clean once the job was completed.

It’s clear they take pride in their work and understand the needs of commercial properties. I’m very satisfied with the quality of the installation and would confidently recommend JM Mechanical of WNY to anyone in need of commercial HVAC services.

I have several rental properties and I have used Erie Niagara heating recently to service several of them and have had a couple of furnaces replaced recently by them. . I am very happy with them. They respond very quickly. They explain everything in detail as to what’s going on and recently in February I had a furnace go completely down. It was over 20 years old and needed to be replaced. They actually brought several space heaters over that night to my tenant until they could get the furnace from the Supply house early the next morning. Couldn’t be happier… highly recommend

Nick and Dan were so helpful! They came quickly to replace our completely broken furnace when it was VERY cold out. Replaced the furnace and AC units. Quick and effective communication and very knowledgeable. 100% recommend!
