Semper Mechanical, INC.

A former employee summed it up well in a 2025 Reddit post: Semper does "a ton of ultra high end" installs that have turned up in magazines, but the same small crew also keeps coming back for the routine annual tune-up. Semper Mechanical is an independently owned HVAC company working out of Beverly, covering Boston, Cambridge, Peabody, Andover and Gloucester with heating and air conditioning installs, repairs and maintenance for homes and businesses. The written history backs that range up: 82 reviews since 2020 across three platforms, a 4.9-star average from 83 Google ratings, BBB accreditation at an A+ grade, and 4.8 stars on Thumbtack from 17 ratings. Its HVAC license is active on the state registry. Several reviews describe homeowners comparing multiple quotes before choosing Semper for a full system replacement — a dual heat pump project in 2025, a complete HVAC swap finished within a week that same year, and a ductless mini-split job in 2026 after other quotes fell short. The same technicians show up by name across dozens of reviews for annual maintenance — Dan especially, and Karl, who one customer says they specifically request every year — and when a billing mix-up came up in 2026, the owner, Billy, called the customer back himself within minutes. Two things are worth asking about. A 2026 review describes a ductless system installed five years ago that has needed repeat service, draining completely every couple of years since. And an Angi review from early March 2026 describes a slow response and a delayed parts order during a no-heat emergency in a snowstorm — worth asking how they handle true after-hours urgency before you need it. Semper is a strong call whether the job is a custom multi-zone install or a yearly checkup on an aging furnace, and the owner's own involvement is a real reason to trust the response when something goes wrong.
