A homeowner writing in December 2024 said TJ's had been servicing his system for about twenty years. That is the shape of this Littleton HVAC shop's record — a lot of repeat customers who call the people who show up by name. The state registry lists Tyler Janeczko as the holder of an active Massachusetts HVAC license, and reviewers call the owner Tyler. Across 70 Google ratings averaging 4.6, the same handful of names recur: Phil on the annual tune-ups, Travis and Joe on repairs, Beverly in the office. Customers writing in 2023 and 2024 described eight- and ten-year relationships covering furnaces, central air, mini-split heat pumps and duct work. Price comes up often, and favorably. A June 2026 customer replacing a damaged system said TJ's initial estimate landed $4,000 under a competing quote for equivalent equipment. Later that month, another described a full sunroom system — air handler and outside condenser — going in during a single day at what they called a reasonable price. A 2024 reviewer who had six companies out said Tyler was the most direct of them, and a 2024 mini-split job was structured around MassSave rebates and financing. The complaints deserve a read, and the recent ones carry the most weight: two of the last six reviews are negative. In April 2026 a customer said two technicians spent fifteen minutes on dripping AC vents, blamed the roof, would not listen, and charged $225. In October 2025 an 11am maintenance appointment had the technician arriving at 2:30pm with no advance notice. In July 2025 a reviewer said the suction line on their system was installed without proper insulation, and pointed readers to the owner's reply to judge for themselves. A January 2025 customer said the technician cycled the furnace off and on and little else. Against that, an October 2025 reviewer wrote that Jim declined a tip, didn't charge for anything unnecessary, and said plainly they weren't sure where the other complaints came from. TJ's is a sensible call for furnace and AC replacement, mini-splits and annual maintenance, particularly if you want a quote to hold up against a larger outfit. Ask what a diagnostic visit costs and what happens to that fee if the cause isn't found, confirm the arrival window and who calls if it slips, and on an install get line insulation and commissioning written into the scope.
“We have had good experiences working with TJ’s http://www.tjsheatingandair.com”
Very professional, courteous and knowledgeable!
Tyler, the owner of TJ’s HVAC was great to deal with and they installed a full new system in our sunroom, including an air handler and outside condenser in one day at a very reasonable price. We definitely recommend them! Thanks, Bert.
We cannot say enough great things about our experience! From start to finish, the team was professional, knowledgeable, and an absolute pleasure to have in our home. They thoroughly cleaned our HVAC system and, most importantly, identified and resolved our indoor air quality issue — something we had been struggling with for far too long. Tyler is outstanding. His expertise and attention to detail gave us complete confidence that the job was being done right. It’s rare to find someone who truly takes the time to explain what’s going on and genuinely cares about the outcome. Our home feels so much better now — the difference in air quality is noticeable and we couldn’t be more relieved and grateful. If you’re dealing with humidity issues, poor air quality, or just need your HVAC system serviced, look no further. We highly recommend this company and are so thankful we found them. They’ve earned a customer for life!
TJ's HVAC helped replace our HVAC system after it was damaged. The initial estimate they sent us was $4000 less than a competing estimate from another HVAC company, even though the equipment was equivalent. They were very transparent and responsive throughout the process. They were able to schedule the replacement really promptly even though we were entering their busy summer season. Excellent work from start to finish.
TJ’s brought two people to our house to check on why our AC vents were dripping water. They spent all of 15 minutes looking around and said it was our roof leaking. It was clearly not our roof leaking, but they would not listen. Then they charged $225 for this 15 minute incorrect assessment where they hardly looked at anything. I have never had a contractor charge such a high price for coming out for such a short amount of time (and to offer incorrect information). I tried to express my concern and offered to pay for the 15 minutes they were here instead of the full one hour rate, but they said they charge $225 for all assessments. I guess this was on me for not asking how much it would be. However, I still find this to be a very high price especially for such a rushed assessment and poor experience. After their visit, I called Nashoba Air & Boilerworks. A person came out and diligently checked each of our AC vents, took time to check our thermostat, thoroughly reviewed each of the ducts in the attic and found the issue and told us out to resolve it. It was an easy, low-cost fix we did that day and it was NOT our roof leaking. Nashoba was much more knowledgeable and was able to solve our problem! They were also extremely thorough and charged a much more reasonable price. I can’t imagine how bad it would be if I had trusted the misinformation I was given, gotten a new roof and still didn’t have the problem resolved! I write this to save you time and money- don’t use TJ’s unless you want a short, expensive visit where they don’t solve your problem and tell you wrong information!
