"Don Therrien is brilliant. He has worked on my furnaces, AC etc. and is the only person I would ever trust to fix anything in my home. He is honest, right on target with diagnosis of whatever the problem is AND he is HONEST and will not rip you off. His prices are very reasonable. I have referred him to all of my friends because he is that good. Hire this guy if you need HVAC services."
