Great sales and service. Had my last home in Stow serviced by Brennan and everything worked great. Installed all new furnace system and things were even better. Fast foward to spring 2017 in our new home and one of the two AC units were failing. With 90 degree temps and a 12 month old in the zone of the down unit, Brennan responded quickly and replaced the old unit.

They also replaced the large unit which was only months from going down as well. All went great, great price, great service and better people. Ive referred family and friends to Brennan who also speak very highly of their work. Thank you

Recently moved into a new house, and our furnace had multiple tags on it saying it was last serviced by Brennan. The last service date from Brennan was earlier this year. Our furnace went out, so we contacted the last company to service it- Brennan. After 2 hours, they returned our call and rudely told us they don't service our area, and they didn't want to deal with our home warranty. No problem, I'm sure there are plenty of other companies that would like our business
