"Don is a phenomenal professional. I understand little to none about plumbing and he easily explained what needed to be fixed. He s a genius at this. We were under a super tight timeframe and not only did he accomplish it well within that, it was done perfectly. I was lucky to find him when I needed a new boiler and both jobs were fairly quoted, unbelievably executed and added significant value to my home. If you fix problems the right way when things break in your home (and they will) you will get that money back when you sell it. Count on it. If you have a problem, don t wait. Call Don. You will be so happy you did."

"I hired Kenyon AP to do an install of a high efficiency wood furnace in parallel to my existing LP unit. Eric did the full install, including fabricating a custom plenum to mate it to my existing ducting. He came back to revise some of the work at no charge, and did a very thorough job. He was quick, responsive, professional, and accommodating. He's also a wizard with sheet metal, and a great guy to just talk to. Very personable. He takes his work seriously, he's honest, and he will see the job through until the work meets his standards. Eric shows a commitment to quality work that is honestly pretty rare in contractors, in my experience. I plan to hire him again for any HVAC needs!"
