The honest answer: it depends on the boiler
A routine annual service on a small commercial hot-water boiler is a few hundred dollars. A full teardown inspection on a 800 HP firetube with combustion analysis, tube inspection, and refractory checks is a different job entirely — and priced accordingly. Anyone quoting one flat number for every boiler sight-unseen is guessing.
The real drivers are boiler size and type (firetube, watertube, condensing), steam versus hot water, how accessible the equipment is, whether the boiler has been maintained or neglected, and what your jurisdiction requires for code inspections.
What moves the price
When our technicians scope a service, these are the factors that matter:
- — Boiler horsepower and configuration — a 50 HP firetube and a 250 HP watertube are not the same visit
- — Steam boilers need more attention than hot water: low-water cutoffs, safety valves, and trim demand testing
- — Condition of the fireside and waterside — a neglected boiler turns a service into a repair
- — Combustion tuning — fuel savings from a proper tune often pay for the service by themselves
- — Code requirements — annual internal inspections on steam boilers in most jurisdictions
Why a maintenance agreement beats one-off calls
Servco preventative maintenance agreement customers get scheduled service, priority scheduling when something breaks, and a 10% discount on all parts orders. The math is simple: a planned service visit costs a fraction of an emergency call with production down — and a tuned boiler burns measurably less fuel every single day.
One unplanned outage usually costs more than a decade of annual services. That's not a sales line; it's what our customers tell us after the first one.

Quick answers
How often should a commercial boiler be serviced?+
At minimum annually, with combustion checks each heating season. Steam boilers in most jurisdictions also require annual code inspections. High-use process boilers benefit from quarterly attention.
Does a boiler service save money on fuel?+
Yes. Combustion tuning alone commonly improves efficiency by 1–3%. On a boiler running most of the year, that typically exceeds the cost of the service.
What happens if I skip boiler service?+
Efficiency drifts down, small problems compound, and failure risk climbs. The most expensive boiler service is the one that turns into an emergency repair with your facility offline.
