Bryan came out to help diagnose the issue we were having with our Furnace. He was extremely patient and thorough explaining the overall issue. I would highly suggest him for HVAC needs.
I was impressed with how fast Bryan came to my rescue. I called and he was here in 45 minutes to check out my situation. And IO called late in the day. Picked up a new unit and parts for my furnace the next day. Came pout the next day at 8:00 am and installed everything. I couldn't be happier and more satisfied with his service, his knowledge of my system, his price, and how fast he had me back in cool air again. I would definitely recommend McMaster Mechanical.
I don’t know why it took me this long to write this, but if you’re looking for someone trustworthy, skilled, extremely knowledgeable, and genuinely caring in the HVAC world, Bryan Heer is that guy… We have been lucky to have been using his expertise for about 3 years now. He’s helped our family through multiple HVAC issues—from giving my mom’s aging condenser a second life (so she could buy time to save for a full replacement), to tackling a poorly-installed, Mickey-Moused furnace in our new home.

Referred from my neighbor who had nothing but great things to say. Bryan came and instantly I felt very comfortable that he was knowledgeable and honest. His pricing was very fair and I would definitely call him again for help. He never tried to upsell me or push me in a direction of spending more that I needed to like other HVAC mechanic language done. If you can wait to book him, it would be the smartest thing you could do.
Bryan did an excellent job fixing our evaporator coil. He was very professional, explaining the issue clearly and upfront, which gave us confidence in the work being done. He was efficient and made sure everything was working perfectly before finishing up. We highly recommend his services for anyone needing HVAC repair.
