Awesome Family Company to Work with and will be calling them for everything!
V.M. O'Leary Sheet Metal & Heating is the best company I have ever worked with when it comes to issues with my home. From the minute I called them to the minute the work was completed I couldn't have asked for more. The owners are wonderful people and the techs know their stuff and made me feel at ease with the entire process!

Vince and his entire staff did a wonderful job of solving my air conditioning problem. They installed a new system very quickly. Everyone involved in the installation were very professional and a pleasure to work with. I have used Vince for all my Furnace and Air Conditioning need for over 20 years. I very highly recommend them.

Personalized Care
We got several estimates to install air conditioning in our house All estimates came by email. O'Leary's was the only company that came to the house and explained the process and gave us options. This personalized service was the reason we chose O'Leary's. It took 3\-4 guys 8 days install everything, which included wiring, duct work, and air handlers. We had special circumstances, an old house with hot water heat, an addition that was difficult to get to. The vents and return vents fit into our high ceilings and look great. We are eager to experience summer and try out our AC without having to put in window units. We are very happy with O'Leary's knowledge, quality of service, genuinely nice company to work with.

Amazing, friendly and flexible
They were amazing. Our heat gave out and they were able to look at it that day. I am teacher so I was unable to get out but they worked with my schedule. They were very upfront with costs associated with the furnace and worked with our somewhat funky old house duct work to install a furnace in less than a day. The tech, Charlie, was very knowledgeable and friendy

True Craftsmen!
We are so pleased with the work that VM O'Leary performed regarding the purchase and installation of our new furnace and air conditioning units in our home. To start off with, Vince's responsiveness via telephone and in\-person was phenomenal. He took the time to explain the various options we had on Bryant equipment and the benefits of each choice. The proposal was very reasonable. They were able to complete all of the work within a very short time. VM O'Leary's team, Daniel and Charlie, did a fantastic job from start to finish (including cleaning up when they left the property)...they were definitely perfectionists...true craftsmen. VM O'Leary's professionalism, quality and craftsmanship is excellent! We would HIGHLY recommend them to any potential customers.

New furnace and A/C
Vince was very helpful in determining size furnace and A/C for my house. His crew (Daniel and Charlie) was on time and explained each item installed. Also, Charlie noticed my sump pump was running but not injecting water. I called another contractor and they replaced pump. Judy did a terrific job with paperwork (rebates) and communicating schedule.
