Don did a great job servicing my home furnace, and was descriptive about potential issues it could have. He showed me an issue with the motor not kicking on and rather than try to sell me a new motor, he tinkered with it for a few minutes and discovered a disconnected wire rather than give up and sell me an unnecessary motor. I respect honesty above all else in service, and Don delivers. He's definitely the guy I'll call when I need heating service again.

Don sets the standard! He is everything you would need in a contractor these days when many others fall short. The communication and work was done to complete satisfaction with many aspects of the job where he went above and beyond expectations. A+

Don was friendly, efficient, and did a great job cleaning our furnace last Friday! He will be our new "furnace guy"! Glad I saw the recommendations for him!!

Had Donny come over and service my system. He was on time, and his communication was key. Will be using him in the future.

Great work by a local tradesman. Don returned our call quickly, and showed up when he said he would for our annual cleaning. Fair price and thorough job.

Showed up on time. Very friendly and knowledgeable. Took the time to explain the service my furnace needed. Very happy with the final bill. Definitely will use again and recommend to others.

Don recently replaced the furnace at my home, replacing an old system that had failed after 30+ years with a brand new one. The job was done quickly and it is running great. Just a couple of days later, I had a heating system issue at a rental property I own in Athol. Don was there within an hour and repaired it, serviced and cleaned it and got it running. I would highly recommend him.

Donny was able to fit us in quickly and did and excellent job! He's kind and professional and we'll definitely be calling him for any maintenance or repairs to our heating system in the future.

I had Donny come in and clean my furnace yesterday, he did the most through cleaning and inspection of my furnace that was ever done by any other tech. He spent the time to make sure ever part of it was working like new and also did an efficiency test.
I highly recommend Knapp home and heating maintenance for your boiler needs.
