First Class TinKnocker, LLC

Jason, Nellie, and the TinKnocker team are the best of the best! We had a complex HVAC heating and cooling installation in an old two-family home, and they handled every challenge with patience, precision, and care. They take the time to explain everything so you’re never lost in the process, and Nellie keeps the administrative side running seamlessly - especially if you’re working through the Mass Save program. Their workmanship and professionalism were outstanding from start to finish. Highly recommend them for any HVAC project!

Jason, Nellie and the rest of the crew have been top notch, answering all my questions — excellent service on installation day and follow ups, including navigating all the paperwork to get the tax credit. I really respect the work they do and how responsive they’ve been, from initial quote to working with MassSave, etc. I highly recommend these folks!

I would highly recommend Jason and his team. We had an emergency issue with our HVAC heat (they were not the initial installers). I reached out to Jason, he came out within 48hrs, was very knowledgeable and helpful. Our heat is now back and in working order. Will definitely use again!

I cant tell you how thankful I am for Jason and his team for coming out. I've had a problem with my heat pump system since a different company installed, and have went through 3 different companies to diagnose and fix and thousands of dollars later to have it fixed in under an hour with Jason and Manny. Highly recommend.

Very responsive and respectful. They did excellent work and we are very happy and comfortable. Even a year later they were willing to come out and check our system. Highly recommend working with the Jason and team.
