Emergency generator service costs 3–5× more than preventive maintenance. But that multiplier isn't even the number that should worry you.
Here's the real math:
→ PM Contract — A fixed, scheduled line item. Predictable cost, planned into your budget, no surprises.
→ Emergency Service Call — Several times the cost of a routine PM visit once you factor in after-hours rates, rush parts sourcing, and priority dispatch.
→ The Failure Itself — Lost productivity, missed deadlines, potential compliance exposure, and in critical facilities, risk to people who depend on that power. This is the cost with no fixed price tag — and it's almost always the largest one.
The math isn't complicated. The facilities that budget for PM avoid paying for the other two.
