Nautical Heating and Air Conditioning

Nautical Heating and Air Conditioning works the South Shore out of Marshfield, and almost every one of its 11 Google reviews credits the same person by name: James. The company says it was founded in 2022 by James Triglia, who owns and runs it, providing residential and commercial heating, cooling and refrigeration installation, service and repair. It's a Mass Save Certified Partner and an authorized Mitsubishi Electric dealer, and it offers free estimates. On Google, it holds a 5-star average from 11 ratings, and every review on file is five stars. In a recent review, a customer said James's crew replaced a water heater and installed a smart thermostat with new heating and AC vents in their basement at a great price. Another recent reviewer credited a technician named Kyle with refilling their system at a fair price, calling him 'not a salesman, just a guy who wants to do the job right.' In a 2025 review, a homeowner whose AC failed during a 90-degree stretch said James fit the repair in on his way to another call; another 2025 reviewer said James completed a central AC installation using their existing ductwork in a single day. For anything from a furnace swap to a same-day AC install on the South Shore, this is a small, owner-led operation with a consistently positive record on Google so far.
