BAS and AI fault detection run plants remotely; most states dropped boiler attendance rules, so only NYC-type stationary engineer licenses keep a few techs.

AI impact · ShrinkingStationary Engineer (Boiler Operator): what AI changes and what stays
A boiler and HVAC operator's shift means walking through mechanical rooms listening for a leak or an odd noise, adjusting burners, water levels and refrigerant by hand to keep systems balanced, and rushing to a building on-site the moment heating or cooling actually fails.
What's already running these systems without an operator?
Building automation systems paired with AI fault detection can now monitor equipment and flag problems remotely, which is why most places have dropped older rules that required someone to physically watch a boiler at all times. That remote monitoring covers routine oversight, but it still can't walk into a mechanical room to adjust a burner or physically fix what's actually broken.
Why do a few places still require an operator on site?
A small number of cities and states still license stationary engineers and require someone physically present for high-pressure boilers specifically, treating that as too dangerous to leave unmonitored. Outside those few places, unions mostly negotiate the order in which jobs get cut rather than stopping the shift toward remote monitoring, so this trade is shrinking unevenly depending on where you work.
How does someone enter this trade today?
Where a license is required, it usually comes through years of supervised experience in mechanical rooms rather than a college program, and in places without licensing requirements, most people learn on the job under an experienced operator. As remote monitoring takes over routine oversight, the skill worth building is fast, confident hands-on troubleshooting for the moments when a building's system actually breaks.
