    review rating 5  Chuck was able to squeeze us in during the afternoon. He was able to troubleshoot why we had been having issues for the past few winters and provide replacement parts for an old boiler right on the spot. A very solid and easy experience!

    review rating 4  They do what they promise! Had an after hours furnace issue on a very cold night. Chiassons was the ONLY place to answer their "24/7 Emergency" number. I called many places and most did not answer and didn't even have a way to leave a message. Of the few I was able to leave a message for only ONE ever called me back. Unfortunately for them it was 20 minutes after I called Chiassons and spoke w/ the owner immediately. Someone was at my house in less than 30 minutes. It took a couple trips to keep the furnace running but they eventually got it and always responded right away. When I replace this old furnace guess who I'll stop in to see FIRST?

    review rating 5  They are the only company I call when needing help. They maintain my boiler which is very old and just last year replaced my water heater for me. They do excellent work with fair pricing, and the guys are very knowledgeable. I would highly recommend!
