Honest, friendly, professional. They assessed the problem and let me know what my options were and did so with no pressure to make a decision right away - which was perfect for the stressful situation we were in with a three year old boiler going bad.

Reviews
Fast and easy service for our AC. Techs were so kind and knowledgeable. Didn’t try to over sell us, would highly recommend to anyone who’s looking for a genuine business.
While I was away on vacation, I received a call from my cat sitter letting me know my heat was not functioning. Someone I trusted recommended Exxel, so I called them.
Bob agreed to fit me in and was at my home the next morning. He fixed the problem and completed the maintenance on my furnace that was required and had caused the problem to begin with, and the cost for everything was less than I was expecting. I typically do not have this type of experience with repairs!
I am so grateful for this extremely positive outcome and highly recommend Exxel Mechanical Services.
