Climate Zone HVAC

Climate Zone is a Haverhill-based HVAC and plumbing contractor, led by Andrew DiPietro, that has been doing ductless mini-split, furnace, heat pump and water heater work in the region for close to two decades — one longtime customer describes using the company since 2005 to install and service 17 mini-split units across seven apartments in a restored Victorian building. The company says it holds Elite Diamond Contractor status with Mitsubishi Electric and Premier Contractor status with Lennox, and it carries an A+, BBB-accredited rating. The bulk of what shows up here, spanning hundreds of five-star reviews into 2026, is routine service done well and fast: same-day AC repairs ahead of a heat wave, a water heater swap completed the Monday after a Friday call, and mini-split installations where crews are repeatedly named and praised by first name — Mike, John, Ray, Aidan, Noel, Manasseh and others come up again and again for being on time, explaining the work, and protecting floors while they're in the house. One tune-up customer who works with HVAC technicians professionally singled out one technician's service as some of the best they'd seen in the trade. A handful of accounts describe real trouble on bigger jobs, though. A 2026 review said a phone quote for a capacitor repair didn't match the price given on-site. Another, from May 2026, describes ongoing comfort problems on the first floor after a $40,000 whole-home heat pump system installed in 2024. A late-2025 review describes eleven months and roughly $2,500 spent trying to get a Mitsubishi heat pump working again, without success by the reviewer's account. A January 2026 review describes a scheduled appointment window with no technician and no call. And a 2022 review of a furnace replacement over $20,000 complained about a loud humidifier the company recommended, audible throughout the house at night. These sit as a minority among the five-star volume, but they cluster around larger installs and slower-moving repairs rather than routine maintenance calls. Climate Zone looks well suited to routine HVAC and water-heater work, where the reviews are consistently strong — get pricing in writing before a bigger install or an unusual repair, and ask what happens if there's a callback.
