Our Services
Associated Mechanical Services (AMS) maintains, repairs and replaces the heating and cooling in universities, institutions and commercial buildings across Greater Boston. Our technicians are members of Pipefitters Local 537.
Scheduled PM visits, repairs done right and replacements planned ahead, so your building stays online.
Boston shop, not a national chain
A team that knows your equipment.
Since 1988, AMS has kept institutional and commercial buildings across Greater Boston and New England heating and cooling. Today that is 300+ buildings and 45+ preventive maintenance agreements.
Our technicians are members of Pipefitters Local 537, and our whole team is OSHA 30 trained. Our team keeps a running history on every unit we service, so a worn bearing gets caught on a PM visit, not during a no-heat call.
You call people who know your building, not a ticket queue.
Something down right now? Call 781-937-8100, day or night.
Core capabilities
Fewer surprises, by design
It starts with a preventive maintenance agreement. We learn your equipment, log its condition on every visit and tell you what is wearing out before it fails. Repairs go faster and replacements get budgeted instead of rushed.
Preventive Maintenance Agreements
Scheduled PM visits built around your equipment: coils, belts, filters, cooling towers and boiler checks.
Repair and Diagnostics
We find the root cause, fix it and tell you what we found. A team that knows the unit works faster.
Equipment Replacement
Rooftop units, chillers, boilers and air handlers, replaced on a plan you saw coming, not after a failure.
Multi-Building and Campus Service
One team and one phone number for every building in your portfolio, from a single RTU to a central plant.
24-Hour Emergency Service
If something does go down, call us day or night.
Who we serve
Universities, labs, campuses, offices, retail, healthcare and mixed-use buildings. See Institutional HVAC and Commercial.
