Brennan’s Heating & Air Conditioning Reviews

“Highly recommend. It is a great experience each time we use Brennan's. Scheduling is easy, technicians are always prompt, efficient, and knowledgeable. We are repeat customers - they've performed regular maintenance for us, quickly helped us with a few urgent items, and installed a whole new heating/cooling unit.”

Brian T.

“The technician was persistent and determined in his efforts to locate a problem with the system. A subsequent follow-up to repair and replace a part was done in a timely manner, and it did require a lot of work. The technician was professional, and he left everything neat and clean. His attitude and pleasant demeanor was a plus.”

Thomas W.

“Brennan's technical expertise and their professionals can't be beat. I would recommend Brennan every time. Mike Brennan has a winning team that's dedicated to providing top quality work at a fair price with great customer service.”
