In almost every energy or utility facility I visit, there comes a moment when someone finally asks: “How much air are we actually losing?”
It’s an important question, and usually a revealing one, because compressed air leaks rarely call attention to themselves. They don’t trigger alarms or cause dramatic failures. They simply bleed pressure, cycle compressors, and quietly add thousands of dollars to your operating costs.
The surprising part is how often plants estimate their leak rate rather than measure it. And almost without fail, when we put real numbers to the problem, the loss is far greater than anyone expected.
If you’re noticing similar reliability issues in other parts of your plant, you might find this overview helpful as it explains why many equipment failures come back even after repairs:

Leaks rarely look dramatic. They show up as loose fittings, worn gaskets, aging piping, corroded joints, or valves that don’t fully seat. One tiny leak might not matter by itself, but when a plant has hundreds or thousands of connections, the cumulative loss becomes significant.
In water and wastewater systems, leaks often hide in long pipe runs or older infrastructure. In gas utilities and industrial energy settings, leaks creep into instrument air systems that run year-round. Chemical and fuel facilities see leaks multiply as equipment ages or cycles frequently.
What seems small individually becomes a major energy burden when multiplied across an entire facility.
A Leak-Down Survey is the most straightforward way to see how much air your plant is actually losing. We isolate the system, stabilize pressure, shut the compressors off, and watch how quickly the pressure falls. The speed of that drop tells you exactly how much air is escaping.
The results often catch people off guard. Plants convinced they have “a few minor leaks” discover that they’re losing enough air to justify an entire compressor running just to keep up. Others find that the real culprit behind their rising energy cost is simply air loss, not equipment age.
Before investing in new compressors, dryers, or automation, it’s smart to understand what your air system is actually doing. Without a baseline, it’s easy to overestimate equipment needs, or worse, purchase upgrades that don’t address the real issue.
A Leak-Down Survey gives you a clear pre-upgrade snapshot:
how much air you’re losing, how hard your compressors are working to compensate, and how much money the leaks are costing you. It’s the kind of clarity that turns assumptions into actionable decisions.
Once teams see the leak-down results, other efficiency issues make far more sense. If pressure is dropping quickly, it explains why compressors run harder. If dryers seem overloaded, the survey often points to moisture-producing leaks or demand spikes. If operators complain about inconsistent pressure, the leak data sheds light on why.
A leak-down test doesn’t just measure loss, it helps diagnose the entire system.
This is why we often pair it with a broader Compressed Air Performance Assessment. When leaks get fixed and controls are optimized, compressors stop fighting each other, energy use drops, and equipment life improves.
Few reliability activities offer such fast return on investment. Lower leak rates reduce compressor run hours, which lowers energy consumption and gives operators more stable pressure control. Maintenance teams experience fewer nuisance issues, and plant managers get a clearer picture of where their air dollars are actually going.
You feel the impact almost immediately.
If your plant hasn’t been evaluated for leaks in the past year, there’s a good chance you’re paying more for compressed air than you need to. A leak-down survey gives you actionable data and a clear roadmap for improving efficiency, reliability, and cost.
Our team handles the entire process, testing, analysis, and system recommendations.
