    Brennan has been doing my HVAC work for about a year now. I have been very pleased with their service and timeliness. Brennan also recently just started doing plumbing work for me and my rental business over the past two months. Thier responsiveness and quality of work on the Plumbing side has been exceptional. For example, I had a pipe break at a house at 8:30 p.m. I called and they were there by 9:15 on an emergency call. I cannot say enough about how impressed I am with their service thus far.

    So impressed with them. I called yesterday about issue and it wasn't even urgent but they came out today first thing in the morning. Identified the issue and the manager brought the part needed and it was fixed within the hour. Amazing service! Thank you!Services: Heating system repair
