Practical HVACR tools for design support, installation, troubleshooting, commissioning, validation and operations — built for the people who work with real systems in the real world.
No login for quick toolsPractical field workflowsEvidence before closure
40 tools & referencesQuick engineering calculations and reference workflows in the current toolbox.
Field to consultantWork Modes help users start from the job they are doing rather than software terminology.
Evidence before closureProfessional workflows retain readings, actions, verification and issued history.
LEAL product boundariesDetailed heat-load and AHU design stay in specialist LEAL products.
REAL HVACR STUDIO UI
See the actual product experience—not a reconstructed screenshot.
These approved captures come from the real release-candidate application. Free Tools is shown logged out; the professional Project uses only sanitized synthetic HVACR data.
ISSUE FINDER & FIXER
Make troubleshooting a workflow, not a guess-and-forget calculation.
HVACR Studio connects troubleshooting to measured evidence, corrective action, retest and closure. The professional workflow does not automatically diagnose faults or silently mark an issue solved.
1ObserveRecord the symptom or abnormal condition.
2CheckUse readings, references and engineering checks.
3DiagnoseWork through likely causes without hidden AI judgement.
4CorrectRecord the action taken and the engineering reason.
5RetestMeasure again after the corrective action.
6VerifyConfirm the result against evidence and acceptance intent.
7CloseKeep an auditable closure trail instead of marking work done silently.
The exact depth depends on the equipment and delivered workflow. Engineering judgement remains with the responsible professional.
Project-bound issue resolution
Persist issues, RCA / Five Whys, corrective action, CAPA, evidence, verification history and professional reporting where supported.

Choose the work you are doing today.
Work Modes are experience filters — not subscription plans. They reduce software jargon and bring the most relevant tools and workflows forward for each type of HVACR work.
Site engineers, supervisors and field coordinators
Site Engineer
Measure, calculate, check, record and report day-to-day HVACR site conditions.
Open work mode →Installation engineers, supervisors and skilled workersInstallation
Practical installation calculations, quantity checks, inspection guidance and field issue resolution.
Open work mode →HVAC and refrigeration service techniciansService Technician

Open work mode →HVAC, pharma and cleanroom validation engineersValidation
Capture acceptance criteria, measurements, evidence, pass/fail decisions and corrective retests.
Open work mode →HVAC consultants, senior reviewers and approving authoritiesConsultant / Reviewer
Review submitted values, methods and performance without duplicating detailed building heat-load design.
Open work mode →Refrigeration engineers, technicians and application specialistsRefrigeration
Refrigerant reference, system checks and progressively deeper refrigeration-cycle analysis.
Open work mode →Facility managers, operators and maintenance teamsFacility / O&M
Plan preventive maintenance, keep equipment history, surface recurring issues and verify maintenance impact against the same project equipment register.
Open work mode →CONNECTED PROFESSIONAL WORKSPACE
When the job becomes more than one calculation, keep the engineering trail together.
Professional capabilities connect the same project and equipment context across measurement, troubleshooting, commissioning, maintenance, performance, action planning and issued records.
Projects & Equipment
Keep project context, equipment and engineering history connected.
Evidence & Calibration
Link readings, files and instruments with traceability.
Commissioning / TAB
Capture measured performance, acceptance and retest history.
Cleanroom Validation
Record criteria, measurements, deviations and verification evidence.
Facility / O&M
Track maintenance, recurring issues and preventive-maintenance work.
Performance
Compare measured equipment performance with captured project or OEM baselines.
Project Health
Bring unresolved issues, due work and degraded conditions into one attention view.
Actions & Closure
Assign follow-up, record completion, verify outcome and preserve history.
Professional Reports
Freeze issued engineering records instead of rewriting history later.

THE LEAL SOFTWARE ECOSYSTEM
One-stop field support without sacrificing specialist design products.
HVACR Studio is the everyday engineering and field-workflow layer. Deeper specialist design stays in the LEAL products built specifically for it.
HVACR Studio
Quick tools, troubleshooting, commissioning, validation, O&M, evidence and professional closure.
Leal Heat Load Calculator
Full room-wise building cooling-load design remains in the specialist Leal HLC product.
Leal GADraw
Detailed AHU engineering and GA drawing automation remain in Leal GADraw.
Odoo ERP Solutions
CRM, sales, purchase, inventory, projects, accounts and connected business-process implementation.
Odoo is a third-party ERP platform implemented and supported by LEAL. HVACR Studio does not include Leal HLC room-wise heat-load design or Leal GADraw AHU / GA automation.
ENGINEERING INTEGRITY
Show the method. Preserve the evidence. Keep judgement visible.
Where applicable, HVACR Studio keeps formulas, assumptions, applicability notes, measured evidence and verification history close to the engineering workflow.
Read about the engineering approach →Transparent methodsCalculation pages show formula or method and applicability notes where relevant.
Instrument traceabilityProfessional records can link measurements to project instruments and calibration history.
Completed ≠ verifiedAction closure distinguishes recording work from verifying the outcome.
Frozen issued historyProfessional report workflows preserve issued evidence rather than silently rewriting it later.
