Brennan’s Heating & Air Conditioning Reviews

“The technician was very knowledgeable and professional. He took great pains to show me everything and explain it all. I would hire Brennan’s in the future without hesitation.”

Gail H.

“On a cold night in early Jan, I noticed that my furnace was not working properly. I called Brennan at 9pm and they were there within an hour. Not only did he diagnose the problem quickly, he was able to 'jump start' the furnace so the house would be warm overnight. Early the next morning, they had the new part ready and installed it that same day. The technician was very professional, courteous, and informed. I will definitely contact them again for maintenance and service.”

Michael M.

“My experience with Brennan's was excellent from start to finish. Their office and sales staff and the installation technicians were extremely courteous and professional. I am extremely pleased with my new air conditioner.”

Carol W.

“Great service. With this being the hottest week of the year with heat indexes in the 105 degree area, I thought we would have to wait a while to get someone out here. But within 3 hours of my call the technician was out here and fixed the problem. They are professional and give advice and reasonable prices.”

Eric M.

“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.”
