    I’m a tough grader when it comes to service, but I have to say High Efficiency truly impressed me. They installed the HVAC system in my antique home on Cape Cod, and today they came by to swap filters and perform a system cleaning. I was particularly impressed with the younger technician working on the mini-splits. He was efficient, focused, and went out of his way to check if the rest of the crew needed a hand. Curious, I asked how long he’d been with High Efficiency. He said about a year and a half, having just graduated from technical school. When I asked how he likes it, he said, “It’s great—they’ve been very good to me. I’m very fortunate.” That’s an impressive answer from a 20-year-old and speaks volumes about the culture at High Efficiency. The service was prompt, precise (they had everything needed to complete the job in one visit), and they left my home clean and tidy. For someone who sets the bar high, this team exceeded expectations. Dr. Kevin Kelly

    Outstanding Heat Pump Work by Joshua (High Efficiency) Joshua from High Efficiency did an exceptional job on our heat pump installation. His workmanship was excellent, but what really stood out was his attitude and problem-solving. He coordinated everything smoothly and even helped us save valuable storage space in the attic, which we really appreciated. He crawled deep into a very narrow cathedral ceiling space to install a much-needed heat supply in our living room—work that most people would complain about or refuse to do. We also had a failing attic ladder, and instead of making it an issue, Joshua adapted and worked through it without hesitation. He consistently went three steps ahead, thinking through details and making sure everything was done right, not just “good enough.” Professional, hardworking, and genuinely caring about the quality of his work. I highly recommend Joshua and High Efficiency to anyone considering heat pump work.
