I called this company to help me with a thermostat that I didn’t know how to work. He had me send a photo of the thermastat and helped me over the phone. What a lifesaver!!

Bi-Yearly HVAC check. Daniel is just honest and does a wonderful job keeping me up on how the system is running and suggestions to keep it running well. I highly recommend Daniel Moore.

I'm a brand new customer and today was my first fall maintenance service with Brennan's. Having been with my previous HVAC company for almost 14 years, I'm only kicking myself that I didn't switch over to Brennan's sooner! I had no idea that such an oustanding company existed. From the office who scheduled my appointment to Adam, the technician who came out today, I was beyond amazed by their outstanding customer service! Adam was absolutely great! He checked numerous things on both of my systems that had not been checked in years and he explained everything to me as he went along! He was very thorough and clean and I've even called and requested for him to be my regular technician! I am extremely happy that I found Brennan's and will definitely be a long term customer!

Just an absolute 5 star shout out to the folks at Brennan's Heating and AC. The girls in office were both caring, personable and very pleasant to work with on an urgent need to get heat into senior house. Aaron was the tch who responded, again very personable, explained fully the issue, swift to perform repairs and minimized costs by not cutting corners but doing a thorough diagnostic scan. Super happy with these folks, in fact requested to be put on their maintenance program. Highly recommend them for all your HVAC needs.

I had a AC, furnace and water heater coming to their end but the person I got for salesperson for my free estimate was horrible, he talked to me like he was doing me a favor when in fact I was trying to do business with them. His name John. I heard good things about this company and i really wanted to pick their company, had cash in hand ready to accept proposal but his attitude turned me away. Horrible customer service when I asked if he could talk to his manager to modify something for me, he didnt even try, he blatantly said no. He could have at least say: hey, let me ask them and ill get back to you. Was that so hard? I dont think so. Now im going to pick another company who would treat me right and value my money.
