NextGen Aire

NextGen Aire is an Amesbury shop whose reviews cluster around two things: full system swaps — oil-to-gas conversions, central air with zoning, mini-split installs — and the ductwork and piping work that goes with them. A recent review described two complete systems removed and reinstalled with duct work and copper piping the reviewer called excellent, plus a walkthrough on programming the new smart thermostats. Google puts it at 4.9 stars from 282 ratings, and HomeAdvisor and Angi both show 4.9 stars from around 39 ratings each. Multiple reviewers describe coming back for a second job after a good first one — one who'd used the company for a mini-split install years earlier said there was 'only one choice' when a new installation came up. A homeowner working through a heating-system replacement, in a review from earlier this year, said the technician laid out the real options rather than pushing the most expensive one, then came back later to install a new boiler cleanly. Emergency calls get answered fast, too — one reviewer had a technician show up 30 minutes after being woken from sleep. Not every job has gone as smoothly. In a 2021 review, a customer described minor installation mistakes on a central-air-with-zoning and oil-to-gas conversion job — an unexpected floor vent, thermostats that needed re-swapping, and pipe insulation the owner had promised but later said cost extra — plus weak upstairs airflow the reviewer attributed to a sizing oversight. A 2022 review said the company responded quickly and professionally but the heating problem itself was never actually solved. Two older reviews, from 2020, mention a subpar first visit that was fixed the next day and a job that came in well above the original quote. NextGen Aire holds an active Massachusetts Home Improvement Contractor license, listed by BuildZoom as verified. The pattern across five years and five review platforms leans strongly positive, and the last six months carry no negative reviews — but the installation slip-ups above are worth asking about directly, especially around sizing for multi-zone jobs and what's included versus billed as an extra.
