J Cooling & Refrigeration is a small, two-person operation that's been running in Winthrop since 1999, owned by John Arone. One thing worth flagging: the Better Business Bureau's profile for the company categorizes it as a plumber — worth confirming what work they actually do, since the name points toward HVAC and refrigeration. With 27 years in business, a direct conversation about current services and recent jobs is the practical next step before booking.
