Kyle Browne's crew replaced an entire HVAC system - heat pump, air handler and three mini-splits - in four days in December 2024, and the customer wrote that the quote had come in as much as $10,000 below the others. Fast and cheaper is what most of KB's customers describe. Tenants left without heat that same December got a furnace scheduled quickly at a fair price; a homeowner whose furnace failed mid-winter in early 2025 had the replacement finished in a day. KB works out of Chelmsford on residential and commercial heating, air conditioning and plumbing, ductless and central. The company describes itself as veteran-owned and says Kyle Browne came out of the HVAC program at Shawsheen Technical High School in 2005, served just under five years in the Air Force in water and fuel maintenance and plumbing, and holds Massachusetts plumbing licence #34630 - the company's own statement rather than a registry check. The jobs people describe go well past swapping a box. A September 2024 customer had new ductwork run through basement and attic, a new boiler installed and the water heater moved. Another that October had air conditioning installed and the plumbing completely redone. Mini-split installs come up again and again, including one where KB brought its own electrician so the whole job ran in a single pass, and several customers mention being walked through the Mass Save rebate process - one 2024 heat pump and ductless job finished ahead of schedule and within budget. A church property manager wrote in November 2024 of using KB since a 2021 home AC replacement, through four repair jobs and a full unit replacement since. The two hard complaints both involve ductwork. In June 2024, a customer who urgently needed a ductwork reroute wrote that the experience left them financially burdened and called the practices deceitful. In January 2026, first-time homebuyers in a 1963 slab house with old ductwork running through the slab posted a one-star account written to help others avoid what happened to them. For a furnace, an air conditioning replacement or a mini-split install around Chelmsford, this is a responsive shop that quotes low and moves quickly. If your job is a ductwork reroute or a slab-house retrofit, get the scope, the change-order terms and the completion date written down before anyone starts.
I am posting this review in the hopes it helps other first-time homebuyers navigate a challenging HVAC situation and avoid this mistake. We recently moved into a 1963 home built on a slab foundation with no basement. The house had old ductwork running through the slab, and we worked with Kyle to replace the old gas furnace with a whole-house Samsung heat pump using the existing ducts. We had been advised by a couple other people to use the existing ducts, but we (and they) were unaware of their condition. During our first winter, it became clear the underground ductwork was compromised. The system produced strong, unpleasant, musty odors, circulated air poorly, and struggled to heat the home. Our electric bill skyrocketed while the house remained uncomfortable. When I raised these concerns, Kyle seemed defensive. He said he had been hesitant to use our existing ducts, noting that the slab connection was rusted out during installation. We did not know how rusted it was until after the system was already installed. As first-time homeowners, we relied on professional guidance about the risks of decades-old underground ductwork, and would have greatly benefitted from a stronger recommendation to not use the existing ducts. The only real solution discussed was installing an entirely new system and abandoning the existing ductwork, without any kind of courtesy discount or offer of financial support. This ended up being a costly endeavor to install a new system with new ducts.
KB Heating & Cooling went above and beyond for my house! We were very impressed with how quickly Kyle and team answered our call/request and how efficiently the job was done. The job was done neatly and professionally. We are very happy. Will be using in the future and would recommend.
Kyle helped us out in pinch when our furnace needed replacing in the middle of winter. He was able to get us in very quickly and completed all the work in a day. He and his team are very professional and easy to work with. They show up when they say they will and I would highly recommend them. We’ll be using KB Heating & Cooling for all our future HVAC needs.
Kyle and the crew did an amazing job coordinating/estimating my home HVAC project and then completing the full project. Super clean. Great price point. And nice guys. Highly recommend.
Kyle and his crew were great. They came in, kept the project on time, and delivered exactly what we agreed on. I couldn’t be happier using him for my project.
