Founded by three controls engineers in Chelmsford, Massachusetts.
FMC has been designing, installing, and supporting building automation systems across New England since 1997. Same company, same phone number, same engineers who show up when something needs a second look.
Buildings that work the way they were supposed to.
-
Our job
Design, install, and quietly take care of the control systems that run a building's HVAC, lighting, and mechanical plant — the parts of the building most people never think about until something goes wrong. Our measure of success is whether the phone stays quiet.
-
How we get there
Fewer subs, more in-house engineers. Fewer promises, more documented work. We'd rather send a technician who has been in your building before than one who has read about it. Over time, that's the part clients tell us they value most.
Our story.
-
1997
FMC is founded in Chelmsford, MA. The first jobs are one-building BMS installs for Eastern Mass. owners who wanted their controls contractor to actually pick up the phone.
-
2000s
Word gets around the Boston property-management circuit. FMC grows into a multi-trade shop — engineers, techs, service, programming — serving commercial, municipal, and higher-ed buildings across Greater Boston.
-
2010s
The work gets harder and more connected. IP-based controls, remote monitoring, and cloud dashboards become part of standard delivery. We invest in graphics, integration, and remote commissioning so our techs can fix things before a client has to call.
-
Today
200+ commercial, municipal, and institutional buildings across New England. National accounts for several retail and life-sciences clients. Still headquartered in Chelmsford. Still the same people on the other end of the phone.
-
Late 2026
FMC introduces BuildingPulse — packaging the real-time monitoring and energy-visibility work we've been doing all along into something easier to buy, easier to explain, and easier to live with after the install is done. Same people, same phone line, with a clearer set of offerings.
The unglamorous parts of running a building, done well.
-
New BMS installations
Design, install, and commission a new building automation system from scratch — HVAC, lighting, and mechanical equipment tied into one coherent controls network instead of five disconnected ones.
-
Retrofits & front-end upgrades
Most buildings don't need a new BMS — they need the one they have to behave. We modernize graphics, replace aging controllers, and rewrite sequences so the existing plant runs the way it was intended.
-
Integration with what's already there
Chances are your building already has meters, chillers, VFDs, and third-party systems with their own protocols. We speak BACnet, Modbus, LON, and the older dialects, and we map them into one view.
-
Dashboards built for your operators
We build BMS graphics and operator interfaces for daily use — layouts that match how your staff actually moves through the building, with alarms that mean something instead of a wall of yellow triangles.
-
On-site service & training
Planned maintenance visits, emergency callouts, and the occasional afternoon walking a new building engineer through their own plant. We teach facility staff how the building actually works — not just how to acknowledge an alarm.
-
Remote monitoring & commissioning
A secure remote-access layer so we can see alarms as they happen, review trends before a site visit, and hand you a working system at the end of a commissioning cycle — without a full truck roll every time.
What it's like to work with FMC.
-
Most of the work is in-house
Design, programming, graphics, field install, commissioning, service — the same company, which means the engineer who drew the sequences is the one we can call at 9pm when something is off.
-
We show up when it matters
Controls problems don't keep weekday hours. Clients stay with us because when the chiller drops offline on a Friday night, the person answering is someone who already knows your building.
-
We know New England weather
Chelmsford headquarters, decades of experience with the region's buildings, cold starts, and humidity swings. We've seen how these systems actually age here — not just how they're drawn in a manufacturer's spec sheet.
-
Results, not promises
We quote what we think we can deliver, and we prefer showing you trend data from a recently commissioned site to telling you what a brochure says we'll save. Ask and we'll walk you through one.
Let's talk about your building.
Tell us what's going on and who you are. We'll tell you honestly whether FMC is the right fit.
