An audit report can identify useful improvements without giving your finance team enough information to fund them. The next decision is which work to approve, what it will cost to implement and how the expected savings will be checked.
If you are planning a compressed air audit in Los Angeles, define the budget questions you want answered before the measurements begin. Our existing guide explaining the broader air system analysis process covers the inspection itself. Here, we focus on turning the findings into costed projects and a practical approval plan.
Start with the annual cost, not the compressor horsepower
Motor size tells you the rated capacity of the equipment, not what it costs to operate every hour. Actual electrical demand changes with load, control mode, pressure and system conditions. To estimate annual electricity cost, you need measured kilowatts, operating hours and the electricity rate that actually applies.
For example, an avoidable average load of 30 kW over 6,000 operating hours at an illustrative $0.20 per kWh equals $36,000 a year in energy. That is a calculation example, not a measured saving or a Los Angeles utility rate. Your facility's demand charges, tariff structure and operating schedule may change the real total.
Turn findings into separate budget items
Air leaks
For leak repairs, ask for the ultrasonic survey findings, the estimated avoidable air demand and the labor or parts needed for each repair group. Include access arrangements and a check after the work. This lets maintenance cost the job instead of budgeting against a general instruction to fix leaks.
Pressure that is set too high
For a pressure recommendation, ask what investigation or corrective work is included in the price. A controls adjustment, filter replacement and piping change are different projects. The proposal should identify the work being funded and the operating conditions the saving assumes.
Unloaded and poorly sequenced compressors
For sequencing changes, separate engineering and controls costs from any proposed equipment purchase. Include testing, commissioning and operator training where required. Ask whether the recommendation depends on a particular production schedule so the financial case reflects the way your plant operates.
Treatment and piping losses
For treatment or distribution work, identify the affected components and the cost of installation, not just replacement parts. Agree on access and shutdown requirements before comparing this item with a repair that can be completed during normal maintenance.
Agree on the financial baseline
Ask for the measured operating period, production context and electricity charges used in each estimate. Keep those assumptions with the recommendation. Finance should be able to see how a measured change becomes an annual dollar figure.
Request a reasonable range where hours, energy prices or the expected reduction are uncertain. A low, central and high case can reveal whether a project is still worth considering when an assumption changes. Label estimates separately from measurements and supplier commitments.
Example: calculate payback before ranking projects
Using the illustrative $36,000 annual energy reduction above, an improvement costing $12,000 would have a simple payback of about four months: $12,000 divided by $36,000, multiplied by 12. Neither figure is a quote or a promised saving. If implementation costs or annual savings change, recalculate the result.
Compare that project with the other recommendations on the same basis. Include installation, commissioning and expected ongoing costs. Check whether projects depend on one another, and ask the analyst to avoid counting the same energy reduction twice across leak, pressure and controls improvements.
What should the report say about payback?
Ask for each recommendation's assumptions: measured baseline, planned operating hours, energy price, equipment cost, maintenance cost and any production constraints. Simple payback is the project cost divided by estimated annual savings, but it does not capture every operating benefit or uncertainty.
Do not promise a specific percentage improvement before seeing the data. Some plants have obvious leaks and poor sequencing. Others already have disciplined controls and little low-cost waste remaining.
Should you replace the compressor after an audit?
Not automatically. A good audit may show that the current compressor is reasonably sized but poorly controlled. It might identify piping restrictions, leaks or a need to revise storage. Sometimes it supports a new unit or variable-speed compressor, but that recommendation should follow the load data.
If replacement is needed, use the demand profile to compare models at the required pressure. A measured requirement is far more useful than replacing a worn machine with the same horsepower simply because it has always been there.
Assign an owner and a verification step
For each funded recommendation, name an owner, agree on a completion date and record the expected effect. Decide which readings will be compared after the change and who will review them. Keep production conditions in that comparison so a quieter month is not mistaken for a successful efficiency project.
Use the results to update the remaining work list. If the first improvements change system demand, review the assumptions behind any planned compressor purchase before releasing that order. The budget should follow the updated operating evidence.
FAQ
Is a compressed air audit the same as a leak survey?
A leak survey can be one part of a full audit. The wider analysis also considers power, pressure, airflow, demand, controls and system performance.
Can an audit guarantee 20 percent energy savings?
No. Any expected improvement must come from the measurements, operating schedule and realistic recommendations for that facility.
How is potential savings calculated?
The report can compare measured energy use with a credible proposed scenario, then apply operating hours and the facility's applicable electricity costs.
Does my plant need to shut down for an audit?
Many measurements can be taken during normal operation, but access and safety requirements vary. Confirm the plan with the technician.
Can an audit help when a compressor keeps running after production stops?
Yes. That is a useful symptom to investigate, though the cause could include leaks, other legitimate air users or equipment controls.
