Plumbing
Commercial plumbing systems — installation, replacement and service across full facilities.
Boilers
Boiler installation, replacement and service for heating and process systems.
Sheet Metal
Ductwork and sheet metal fabrication and installation coordinated with the rest of the mechanical scope.
Control Wiring

Engineering & Design
Design-build, engineering, value engineering and pre-construction support for mechanical scopes.
Preventive Maintenance
Scheduled maintenance that keeps mechanical systems running and reduces surprise failures.

Why KNC Mechanical
Experience you can verify, availability you can count on
Everything below is drawn from how KNC actually operates — no inflated claims, just the reasons owners, managers and general contractors keep a mechanical contractor on their short list.
70+ years of industry experience
Decades of work in plumbing and HVAC across Massachusetts buildings — experience that shows up in how systems are designed, installed and serviced.
Family-owned
KNC Mechanical is a family-owned business. The people accountable for the work are the people who own it.
24-hour service company
For roughly the last decade the company has operated around the clock, so building failures are handled when they happen.
Commercial and industrial capability
The work is focused on commercial, multi-residential and industrial buildings, not single-family residential service calls.
Engineering and design-build
In-house engineering, design-build, value engineering and pre-construction support for the mechanical scope.
Preventive maintenance
Scheduled maintenance programs that keep systems running and give owners a clear view of equipment condition.
24 Hours a Day
Mechanical emergency? We answer.
KNC Mechanical has operated as a 24-hour service company for approximately the last 10 years — for no-heat calls, failed equipment and plumbing emergencies in occupied buildings.
Capability
Built for complex mechanical systems
A commercial boiler plant, a multi-residential riser and an industrial ventilation system are not the same problem. KNC Mechanical works across all three, which means the trades, the engineering and the service department already understand how buildings like yours are put together.
Commercial
Office buildings, retail and mixed-use properties where tenant comfort and uptime are the priority.
Multi-Residential
Apartment and condominium buildings with central plants, shared risers and occupied units.
Industrial
Facilities where mechanical systems support operations, not just comfort, and downtime carries real cost.

Coordinated Scope
Mechanical systems, sheet metal and control wiring delivered by one contractor.
