Service context
State the medium, pressure, temperature range, leak criterion, environment, and governing requirement source.
HVAC & Refrigeration Systems request guide
HVAC requests, built around test requirements.
Share the controlled drawing, service medium, pressure and leak criteria, material, joint method, finish, test plan, requested records, quantity, and timing. Pearson reviews the inputs before confirming an accepted path.

Capability review
This page describes common request types. Available processes, equipment, tolerances, inspection, documentation, and fulfillment are confirmed for each quote.
Overview
Define the service conditions before the component path.
An HVAC or refrigeration request should connect the controlled part or assembly to its medium, pressure, temperature range, joint method, interfaces, environment, test plan, and acceptance records. That context helps distinguish a manifold, tube, duct, enclosure, or fixture requirement without implying a process or result.
Joint and interface control
Describe tubes, ports, seals, bends, joints, mounting faces, electrical interfaces, and protected areas.
Test and record plan
Define test method, conditions, measurement points, acceptance, traceability, and requested records.
Industry request review
Codes, supplier qualifications, process fit, test resources, documentation, routing, and timing are reviewed for each request. No compliance or result is implied.
Quote inputs
Four inputs that start a useful HVAC review.
Provide the controlled service and acceptance information available, then mark open items for follow-up.
- Service definition
- Assembly or part identity, revision, function, medium, pressure, temperature range, environment, quantity, and timing.
- Material and joint state
- Exact material, stock form, source, supplied condition, tube details, joint method, filler, seal, and process history.
- Geometry and finish
- Ports, passages, bends, interfaces, sealing faces, mounting datums, finish, coating and masking, and identification.
- Test and acceptance
- Leak and pressure criteria, medium, method, conditions, hold points, inspection, records, preservation, and packaging.

Copper U-bend and valve context
Define component function, service medium, pressure, temperature range, environment, and governing requirements.
- Medium and service conditions
- Pressure and leak criteria
- Environment and requirement source
Helpful request detail
Include a service-condition note that identifies medium, pressure, temperature, and acceptance criteria.
Requirements are reviewed before capability, routing, documentation, fulfillment, or timing is confirmed.
Request contexts
Common HVAC and refrigeration request contexts.
These examples organize the request without confirming process fit, testing, result, or fulfillment.
Manifolds and valve components
Flow hardwareBlocks, bodies, end caps, adapters, and fittings defined by passages, ports, seals, service, and test criteria.
Ducts, plenums, and enclosures
Air handlingFormed panels and housings defined by gauge, bends, seams, stiffness, interfaces, coatings, and access.
Line-set and tube components
TubingTube sections, bends, adapters, and end forms defined by material, wall, bend, joint, and inspection inputs.
Subassemblies and test fixtures
VerificationJoined hardware and fixtures defined by assembly state, service conditions, test sequence, acceptance, and records.
Quote review flow
From service conditions to an accepted request baseline.
A short review flow keeps the part, medium, interfaces, joints, finishes, tests, and records connected.
- 01
Share the controlled request
Provide the current drawing, model, revision, hvac and refrigeration context, quantity, and target timing.
- 02
Review requirements and authority
Identify governing documents, precedence, approved substitutions, restricted data, and customer-controlled decisions.
- 03
Map process and evidence needs
Connect material, geometry, interfaces, process history, finish, inspection, documentation, and packaging requirements.
- 04
Confirm the quoted baseline
Pearson confirms accepted scope, routing, records, timing, and open questions before work proceeds.
Request readiness
Make the HVAC request easier to review.
Six checks keep service, joint, finish, and test requirements visible before the route is confirmed.
