Facility Running 24/7?
Service in Action
Rooftop Walkdown
Three-person preventive sweep — gas trains, condenser fans, and energy-recovery hoods checked before peak season.
Rooftop Coverage
The work is bigger than one penthouse — Heffron techs move across the entire rooftop plant to keep every connected system in sequence.
Mech Room Sweep
Pumps, heat exchangers, boilers, and pressure-independent valves — verified line by line on every visit.
Controls Diagnostics
BMS troubleshooting from our senior service techs — backed by the as-built drawings we helped produce.
Hydronic Isolation
Isolating a chilled-water riser for service — the kind of careful, in-person work mission-critical plants depend on.
Drive Room
Variable-speed drives are mission-critical service work too — inspected where the pumping logic, power, and controls actually live.
Cooling Towers
Open-air equipment still needs close attention — condenser-water piping, tower access, and cooling hardware walked just like the indoor plant.
Central Plant
Hot- and chilled-water plants share the same mechanical room — and the same Heffron tech walking both loops on every visit.
Energy Recovery
Performance data and pipework, side by side — confirming that the heat-recovery loop is delivering the savings it was designed for.
In Memoriam
Heffron Company · 2003 – Present in our memory
Jonathan joined Heffron in January 2003 as a UA Local 602 Steamfitter-Helper and spent his career rising through the trade — overhauling centrifugal chillers, rebuilding cooling towers, and solving the toughest HVAC challenges across the MD/DC/VA region.
As Senior Vice President of Service, Jon led a team of more than 50 technicians serving Biotech, Pharmaceutical, Healthcare, and Commercial clients. His commitment to the values of this fourth-generation family business is the standard our department still measures itself against.
1978 – 2003
A permanent member of the Heffron service team. Mark’s craftsmanship, his quiet dedication to his clients, and the way he carried himself on every call set a standard that has outlasted his years with us.
More than two decades later, his name is still spoken in our shop — a reminder of why this work, and the people who do it, matter.
