Brennan was a great company to deal with. My water heater was 23 years old.... and was working fine, but I was getting nervous about pressing my luck. So, I talked to a rep at Costco and they put me in touch with Brennan. The process was pretty simple, although in my case our water heater was originally installed in an awkward angled roof space / small closet in the upstairs master bedroom. The folks from Brennan came out and took a look at it and we thought it would probably work best to enlarge the entry to that space - just to get the old heater out and the new one in. I cut the hole bigger and ultimately made new access doors to the space... but a crew from Brennan came in and did a great job installing my new water heater. They were right on time, right on budget, and the system works great! I would definitely recommend them if your in the market for a new water heater.

Jesse came right on time and was able to replace my gas water heater pretty quickly. He also told me why I should flush my tank annually by showing me the junk that was at the bottom of my old tank. I drained my old tank for three hours before he came. This enabled him to take out the old tank right away. Overall, Jesse did a great job.

We were very pleased by how efficient and complete the annual servicing of our furnace and AC were. Their time was significant as they went through each part of the system and then adjusted as appropriate. At the end of the servicing they provided a detailed summary document which they went through in detail. Really appreciated their work process and their friendly communications.

Great service. Easy and painless process.
Only minor feedback I would give for improvement is that the installers should take more time to cover what they are having you sign.
They give you prices of paper tell you to initial 6 places and sign, but when you read it they are having you Initial things that they have not explained.
Very minor detail It is just a better customer experience to say “ initial here for.....”
The team was really good and they worked very hard

Thus far my experience with Brennan has been fantastic! Everyone I have spoken to in scheduling has been polite, professional and overall just plain nice. The technician who came out to perform regular maintenance was just as great. I'm still communicating with Brennan on an upcoming repair to my furnace and every time I speak with them I am very satisfied -- they even helped identify that my furnace is still under a warranty period. Will definitely continue to do business with them.
