Industrial Compressed Air System Assessments in Southern California
Choose a system walkthrough or a measured assessment based on the question you need answered. Agree the scope, on-site work, any logging period and reporting deliverables before scheduling.
Two Levels of Assessment
The Compressed Air Challenge (CAC), a joint initiative of the U.S. Department of Energy and the compressed air industry, defines a three-level assessment framework. Toolytics offers the first two levels: walk-through evaluation and system assessment. This is the same framework engineers and facility managers use when evaluating service providers.
Walk-through evaluation · Overview and priorities
The walk-through evaluation is the appropriate starting point for most facilities. The scope covers the full system at an overview level: end-use equipment and air quality requirements, supply-side compressor types and controls, distribution system problems, pressure levels across the system, and visible inefficiencies. The output is a written report with a simple system diagram and documented findings.
A walk-through evaluation is the right level for facilities that have not had a formal assessment, systems with known issues but unclear root cause, and customers who want a baseline before committing to a larger scope.
Measured system assessment · Data and recommendations
The system assessment goes deeper. Readings are taken at multiple locations across the system, establishing a pressure profile from supply to point of use and a demand profile that captures how load varies through the shift or day. The assessment identifies system dynamics: how the compressors respond to demand changes, where pressure drop is concentrated, and how the treatment equipment is performing relative to process requirements. The output is a detailed written report with specific, prioritized recommendations.
System assessment is appropriate for larger or more complex systems, multi-compressor facilities, facilities with significant energy cost concerns that warrant detailed data, and customers preparing for a major capital decision who need defensible data to take to leadership.
What determines the right level
The walk-through evaluation is almost always the right starting point. Whether to proceed to a full system assessment depends on system size, complexity, and what the walk-through surfaces. We recommend the appropriate level after an initial conversation. We do not default to the larger scope.
When an Assessment Makes Sense
-
Energy costs are higher than they should be.
Maintenance condition and pressure drop can affect energy use. The effect depends on equipment, operating hours, electricity cost and the measured condition; it is not a predicted saving for your plant. See the DOE maintenance guidance.
-
You are replacing or expanding your system.
A compressor replacement or facility expansion is the wrong time to guess at what the new system needs to deliver. An assessment before specifying equipment establishes the actual demand profile: real CFM at the point of use, peak demand windows, and load diversity across the facility. Our air compressor sizing guide covers the method we use. The result is an installation sized for what the system actually does, not what it was designed for a decade ago. It also surfaces distribution constraints and aging piping that should be addressed while the system is already being touched. Our installation page covers how assessment data informs the equipment decision.
-
You are having reliability or quality problems.
Pressure that will not hold, moisture in the lines, frequent high-temperature shutdowns, tools and equipment performing inconsistently: these symptoms have specific causes. An assessment identifies the root cause rather than cycling through repair attempts. In systems where the distribution piping has aged (CAGI notes that steel pipe friction increases as it corrodes and ages), or where the original treatment equipment was undersized, the fix is not always in the compressor room. If something needs immediate attention, our repair page covers priority response.
Investigate the system, not a promised saving.
Pressure and air quality
Review pressure loss, leaks, treatment and point-of-use requirements against the operating problem.
Demand and control
Use an agreed measurement scope to understand demand and compressor response. Savings require appropriate changes and verification; a walkthrough alone does not establish a result.
Is a compressed air audit the same as an assessment?
Mostly yes, and in the field the two words get used interchangeably. The Compressed Air Challenge and the Department of Energy define three levels of review, and knowing which one you are asking for saves everyone time.
A walk-through evaluation is a look at the compressor room, the obvious losses, and how the system is controlled. A system assessment adds measurement over time: pressure, flow, and power logged across a real production cycle rather than sampled once. A full system audit is a longer engineering study, typically weeks of data logging behind a formal energy model.
Toolytics does the first two. Most plants that call asking for a compressed air audit need one of those rather than the third, because the losses that actually move a bill are usually leaks, artificial demand, and control gaps, and all three show up inside a walk-through or a system assessment without a multi-week study. If a utility rebate or a corporate energy program specifically requires a Level 3 compressed air audit, say so at the start and we will tell you plainly whether we are the right fit rather than sell you a scope that will not qualify.
In most cases there is no charge for the walk-through. It is how we meet a new plant, and it is often enough on its own. Where a system assessment is the right call, you will know what it costs before we start. After the on-site work, data logging runs about a week and the written report follows about a week after that.
What's in the Written Report
The written report is the deliverable. It covers the full system: what was found, what it means, and what to fix first. The report includes:
System inventory
Equipment documented: compressor type, horsepower, age, and condition. Dryers, filtration, condensate management, and controls noted. Distribution piping layout where visible.
Pressure profile
Supply pressure vs. point-of-use pressure at key locations. Pressure drop across the distribution system identified and quantified. The DOE confirms that every 2 PSI of unnecessary pressure drop reduces system capacity by approximately 1 percent.
Treatment equipment performance
Dryer dew point performance relative to specification. Filter differential pressure flagged if filters are running past their change interval.
Baseline readings
Power consumption, operating pressure, temperature, and dew point recorded at the time of the assessment. Starting point for tracking improvement over time, consistent with DOE Tip Sheet #6 guidance.
Specific, prioritized recommendations
What to fix, in what order, with a plain-English explanation of why. Quick wins and safety items first, longer-term capital decisions after. Where equipment replacement or upgrade is warranted, the report will say so. Recommendations are based on what the system needs; vendor and brand decisions stay with you. If the system is running well, the report will say so. Not every assessment surfaces significant problems.
How an Assessment Works
From first contact to delivered report.
Initial conversation
Call (844) 310-8665 or submit a service request. Tell us what is happening: energy concerns, a reliability issue, or an upcoming replacement decision. Your equipment type, approximate horsepower, and location are enough to determine whether a walk-through evaluation or system assessment is the right starting point.
Scheduling
We confirm scope, access requirements and the on-site visit window. If measurements require data logging, its duration and the written-report delivery date are agreed separately.
On-site evaluation
The technician works through the system methodically: supply side, treatment, distribution, and point of use. Readings are taken and findings are documented in real time. If something needs immediate attention, we will say so on site.
Written report delivered
You receive a written report covering the findings documented during the evaluation, with specific prioritized recommendations. The report is yours: use it to make decisions or take it to leadership. We are available to walk through findings with you after delivery.

Schedule WalkthroughFrequently Asked Questions
-
What’s the difference between a walk-through evaluation and a system assessment?
A walk-through evaluation reviews the system at an overview level and documents findings and priorities. A measured system assessment uses agreed measurements or logging to investigate pressure, demand and performance in more detail. The right scope depends on the facility and the question being investigated.
-
How long does a compressed air assessment take?
On-site time depends on system size and the agreed scope. Any logging period and report preparation are separate phases. We confirm the visit window and reporting schedule before work starts.
-
Will you recommend equipment purchases as part of the assessment?
Yes, when the assessment findings support it. If aging or undersized equipment is contributing to inefficiency or reliability problems, the written report will say so. Recommendations describe what kind of system addresses the issue, not a specific brand. The equipment decision and vendor choice stay with you.
-
When does it make sense to get an assessment before replacing a compressor?
Almost always. A compressor replacement based on the specs of the outgoing unit repeats whatever was wrong with the original installation: wrong size, wrong type, inadequate storage or distribution. An assessment before the replacement decision establishes the actual demand profile and surfaces constraints in the existing system. It gives you defensible data for your equipment decision, and it often surfaces distribution or treatment issues that should be addressed at replacement rather than inherited by the new system. See our installation page for how we use assessment data to spec a replacement system.
-
What happens after the assessment, and do you also do the repair or maintenance work?
Yes. The assessment report is a standalone deliverable; you can act on it however makes sense for your facility. If you want Toolytics to carry out the recommendations, we can scope repair work, set up a maintenance program, or spec a replacement installation based on the findings. The assessment is the starting point, not the end of the relationship.
-
Do you do compressed air audits, or only assessments?
We do walk-through evaluations and system assessments, which is what most plants asking for a compressed air audit actually need. A full Level 3 system audit is a multi-week engineering study with a formal energy model behind it. If a utility rebate requires that specific scope, tell us at the start and we will say so rather than sell you something that will not qualify.
-
Is there a charge for the walk-through?
Contact us to confirm whether the initial walkthrough qualifies for a no-charge visit. A measured assessment or additional work is separately scoped and any fee is confirmed before work starts.
-
How soon do I get the report?
The reporting schedule is agreed with the scope. Where data logging is needed, the logging period is confirmed separately from the on-site visit and report preparation.
Serving Los Angeles, Orange County, and the Inland Empire
We run compressed air assessments for industrial facilities across the region, from walk-through evaluations to full system assessments. What changes between these areas is logistics and the conditions we look for, not the method.
Los Angeles County
Vernon, City of Industry, Carson, Long Beach, Santa Fe Springs, Torrance, El Monte, and Compton. Assessments are scheduled around your production window, including off-shift starts where the compressor room cannot come down during the day.
Orange County
Anaheim, Santa Ana, Garden Grove, Fullerton, Buena Park, and Brea. On tightly packed plant floors a single badly regulated drop can raise header pressure for everyone, which is the kind of thing a walk-through catches in an hour.
Inland Empire
Ontario, Fontana, Riverside, Rancho Cucamonga, Moreno Valley, San Bernardino, and Pomona. Larger footprints and longer distribution runs, so pressure drop between the compressor room and the point of use is worth measuring rather than assuming.
Las Vegas Metro
Las Vegas metro requests are coordinated by scheduling. Contact us to confirm equipment, location and scope. See Southern Nevada service coverage.
A note on timing an Inland Empire assessment. Compressor rooms out here regularly run above 95 to 100°F through the summer, and air treatment that looks fine in March can drift badly in July. An assessment carried out in mild weather will not capture the dew point excursions or high-temperature faults that only appear in the heat. If a facility has reliability problems that seem seasonal, time the assessment to catch the conditions rather than the calendar.
