Fault codes, symptoms, equipment context, history and measurements.
Evidence-Based HVAC/R Diagnostic Intelligence
Find the cause. Prove the fix.
AQLYRON is a software platform in active development for HVAC/R field technicians and service organizations. It is designed to connect symptoms, measurements and traceable technical evidence to the next safe, high-information diagnostic action.
Prototype and technical validation in progress

The platform
Diagnosis is not a lookup table.
AQLYRON is designed around a reasoning loop that continuously reduces diagnostic uncertainty instead of presenting generic troubleshooting lists.
Reason
Build and update competing fault hypotheses using available evidence.
Discriminate
Select the safe measurement with the greatest diagnostic value.
Verify
Confirm the root cause and verify that the repair actually corrected the failure.
Diagnostic intelligence
From symptom to supported conclusion.
AQLYRON is being designed to compress the diagnostic tree: preserve what has already been tested, rank the remaining hypotheses and select the next safe measurement with the highest diagnostic value.
OBSERVATION
Outdoor fan does not rotate while cooling demand is active.
Compressor operation confirmed. Fan command path requires discrimination before component replacement.

Support cause and prove repair
Completed valid tests remain part of the case so the diagnostic path does not restart from zero.
Component replacement should follow discriminating evidence, not simply the presence of an error code.
Technical facts must match equipment, revision, operating state and measurement context.
The workflow continues beyond finding a likely cause to confirming that the corrective action resolved it.
One diagnostic intelligence platform
Built for the technician. Designed for the organization.
AQLYRON is being developed as one technical intelligence system with two complementary operating layers: a field workflow for diagnosis at the equipment and an enterprise layer for service quality, asset intelligence and technical knowledge across the organization.
AQLYRON FIELD
IN DEVELOPMENT
Master-engineer reasoning at the point of service.
A field-first diagnostic workspace intended to reduce unnecessary measurements, preserve completed work and guide the technician toward the safest high-information next test.
01
Capture
Symptoms, context, measurements and completed tests
02
Reason
Rank competing fault hypotheses against evidence
03
Discriminate
Select the highest-value safe measurement
04
Verify
Confirm cause and prove the corrective action
Next-Best-Test
Prioritizes the measurement most useful for separating the remaining plausible causes.
No-repeat diagnostics
Valid completed tests remain part of the case instead of restarting the troubleshooting process.
Technical Memory
Field-ready technical facts retain their source, revision, applicability and measurement context.
Advanced electronics
Architecture supports reasoning across rails, rectifiers, drive stages, sensing, communications and feedback paths.
AQLYRON ENTERPRISE
PLATFORM ROADMAP
Turn field service into a measurable engineering system.
An organizational intelligence layer intended to connect diagnostic quality, asset history, workforce capability, recurring failure patterns and private technical knowledge.

First-Time-Fix Intelligence
Connect likely failure, required tools, technician capability, parts context and asset history.
03
Digital Technical Twin
Build structured technical history for each asset across failures, measurements, repairs and verification.
04
Diagnostic Quality Control
Detect missing evidence, unsupported conclusions and recurring diagnostic weaknesses.
05
Failure Signature Engine
Combine electrical, thermal, pressure, timing, communication and historical patterns.
06
Private Technical Intelligence
Preserve organization-specific knowledge while keeping field experience distinct from OEM technical evidence.
FIELD
One verified service event
ENTERPRISE
Becomes organizational technical intelligence
Technology
Deterministic engineering where possible. AI where it adds value.
Calculations, limits, applicability and safety rules should remain deterministic when they can be. AI is used where it adds value for semantic extraction, synthesis and difficult reasoning; it is not treated as the source of technical truth.

Development architecture
Built to move from technical evidence to scalable diagnostic services.
AQLYRON is currently at prototype and technical-validation stage. Development focuses on a traceable evidence pipeline, deterministic engineering services, model-assisted reasoning and cloud-ready infrastructure for secure document processing and diagnostic cases.
Technical document intelligence
Versioned OEM documents, page-level provenance, applicability and reviewed technical facts are kept separate from model-generated inference.
Model-assisted reasoning
AI supports extraction, synthesis and complex reasoning while deterministic rules retain control of units, limits and safety constraints.
Secure cloud services
The architecture is being prepared for scalable storage, document processing, inference, observability and organization-level access control.
AWS evaluation
Current development evaluates AWS services, including Amazon Bedrock, for managed foundation-model access and cloud experimentation as the platform progresses toward an MVP.
AQLYRON is not affiliated with or endorsed by AWS. References describe technologies being evaluated during product development.
About
Built from real HVAC/R field-service problems.
AQLYRON is an evidence-based HVAC/R diagnostic software platform currently in active development by SERVICE AC FRIGO SRL, a Romanian company established in 2023.
The product is shaped by practical HVAC/R diagnostics, maintenance troubleshooting, electrical and refrigeration measurements, and electronic control-board fault isolation. This field experience informs AQLYRON's requirements, safety constraints and validation methodology.
AQLYRON is a separate software product, currently pre-commercial and under active development. Its initial users are intended to be HVAC/R technicians, service organizations and technical teams that need traceable, measurement-driven diagnostic workflows.
