What Our Clients Say

Real feedback from businesses we've served

M

Michael's Frozen Custard

"Great service, easy to work with and great communication. We recently had our rooftop heat exchanger replaced and they were quick to give us a quote. It was half the price of what our heating company in Madison was charging. Scheduled the install the service techs showed up on time, knew what they were doing and they were out done before we even opened. Loved working with them, would definitely use them again."

"I recently hired Bredan Mechanical to redesign and upgrade the HVAC and pipe systems in our commercial facility, and I couldn't be more pleased with the results. From the outset, their project manager took the time to understand our operations, our needs, and our long-term goals. They presented multiple solution options (not just "this or nothing"), and explained the trade-offs clearly. Their in-house design, fabrication, and installation teams worked in sync, which meant fewer delays and communication gaps. During construction, the crew was professional, responsive, and kept the job site orderly. They were careful not to interrupt our normal business flow, which was very important to us. Anytime I called with a question or change, I got a prompt, clear answer. When the system was up and running, performance was excellent. The climate control is more consistent, energy use is noticeably lower, and maintenance has been straightforward so far. Bredan also provided full documentation, testing reports, and walked me through system controls in person, which I appreciated. If you want a mechanical contractor who delivers high quality, sticks to schedule, communicates well, and delivers real value instead of unnecessary extras, I'd absolutely recommend Bredan Mechanical. They've earned my trust and more future business."
