Southern Zone HVAC Inc

Fifty-seven permitted projects, and BuildZoom's read of the last four years is that almost all of them are HVAC. Southern Zone HVAC Inc works out of Raynham, and its permits map a wide arc of the metro area rather than one town — a cluster in Somerville, Brookline and Quincy, then single jobs in Milton, Arlington, Malden, Newton, Cambridge, Medway and Boxborough. One of those single jobs is on Nahant. In September 2022 the company pulled a $21,000 sheet-metal permit at 25 Willow Road to install two HVAC systems in one house: one in a second-floor mechanical closet with a chase duct running to the attic, the other in the basement feeding the first floor. That is a real, specific piece of work — a two-zone retrofit in an older home — and it is the only time this company appears on the island. On licensing, BuildZoom lists a Massachusetts Sheet Metal Business licence as active as of February 2026, which is the right credential for ductwork and mechanical installation. It prints no licence number alongside it, and it is the directory's entry rather than a check run against the state here. The missing piece is any customer voice at all — no reviews on BuildZoom or anywhere else. Fifty-seven permits say the company files paperwork and gets inspected; they say nothing about scheduling, pricing or what happens when a system needs a callback. Worth a call if you want a two-zone system put in properly, particularly given the sheet-metal licence. Ask for the licence number and check it with the state's E-Licensing board yourself, ask whether Nahant is genuinely within the range they will service from Raynham, and ask for a Somerville or Brookline reference — those are the towns where they actually work most.
