Rod from Donahue’s came to my house on time and prepared to clean my furnace. I had my brother-in-law be at my house since I was at work. Rod discovered that I had problems with my furnace. He ordered the part that was needed and this was delivered before I got home. My furnace was fixed!!!! Rod did great work!!!! I would recommend Donahue’s to all.

This is HANDS DOWN one of the best local companies around. I have never experienced customer service and support like I have from this team. Several members of Dave’s team (Rod, Bryan, Mel, Jeremy, Jamie, and even Dave himself) have been there to quickly dispatch someone to help resolve our furnace problems, proactively repair issues and also educate us along the way to help prevent any future problems.
