Warranty & After-Sales Support

Overview and scope

Delta M&E is a Guangzhou-based HVAC equipment distributor and project supplier. This page provides general information for international B2B buyers; the support included in a particular transaction is confirmed before order acceptance.

Warranty, inspection, claims, and after-sales arrangements are subject to the applicable quotation, sales agreement, and mandatory law.

Hitachi project installation and commissioning

Our Hitachi business focuses on commercial and industrial HVAC projects. A project quotation may include equipment installation, commissioning and agreed after-sales services. The scope depends on the equipment, destination, project arrangements and signed contract.

Where agreed, qualified project partners may deliver installation or commissioning services. The quotation should identify the responsible parties, location, site requirements and included work. Manufacturer supply permission, project registration and project-specific authorization must be confirmed where applicable.

Hitachi warranty and after-sales arrangements

Confirm the warranty provider, duration, starting point, covered items, exclusions and claims process for the selected equipment in the quotation and sales agreement. We do not offer a single warranty period for all projects or assume automatic worldwide manufacturer coverage.

Remote technical support, spare parts, partner support and any site attendance are agreed for the project. Worldwide field-service coverage is not included as a standard service; availability and responsibility for local service must be confirmed.

YORK existing inventory and product condition

Our YORK offering is clearance of new, unused existing inventory, rather than a continuing supply program. The equipment was originally supplied in factory packaging. Based on our current inventory records, most YORK main units are from 2022 or later production batches. The manufacturing date and condition of each offered unit will be verified before order acceptance.

Some units may be opened for regional configuration work and repacked before shipment. A unit that has been opened is not described as factory-sealed. Confirm the exact model, batch condition, packaging status, available quantity and destination suitability before order acceptance.

New or originally packaged equipment does not by itself establish current manufacturer warranty eligibility. Any available manufacturer coverage, regional restrictions and required service arrangements must be confirmed for the specific unit and destination.

YORK regional configuration adjustments

Certain main units may require regional configuration adjustments before shipment. Delta M&E may perform this work through its own personnel, subject to the exact model, technical feasibility and agreed order terms. It may require opening the factory packaging and repacking the equipment.

Our configuration work must not be taken as evidence of manufacturer authorization. The required work, packaging status and known functional limitations must be confirmed before order acceptance; configuration success is not guaranteed for every unit.

Regional Configuration and Smart Panel Compatibility

YORK IWE Smart Panel is an intelligent centralized control component. The limitation described here concerns this component; it does not mean that every room thermostat, wired controller, mobile app or YORK control system has the same limitation.

Smart Panel functionality is not supported on affected units after regional configuration. Operating functions, controller compatibility and connectivity must be verified for the exact model and system configuration. Only functions expressly confirmed in the relevant quotation or technical records should be relied upon.

Future Smart Panel availability or restoration is not guaranteed and must not be relied upon as a purchasing assumption.

If Smart Panel or advanced smart-control features are required, tell us before order acceptance so the agreed functional scope can be checked and recorded. Configuration does not establish manufacturer approval, destination-market compliance, international manufacturer warranty or local after-sales service.

• Disclosed configuration limitations

YORK overseas installation and local support

Overseas installation, on-site commissioning and routine local after-sales services are not included by default with YORK stock sales. Buyers should confirm suitable local contractors, service arrangements and site conditions before ordering. Any additional assistance from Delta M&E must be agreed in the quotation and sales agreement.

Reporting product issues and available remedies

Report an issue through our existing email contact channel. Include the order reference, full model, serial number, destination, a description of the issue and relevant photographs, videos or test findings. We normally begin with remote evidence review and may request further checks by an appropriately qualified person.

A verified defect or nonconformity for which the seller is responsible will be addressed with an appropriate remedy. Depending on the findings, remedies may include replacement parts, a reasonable repair contribution, replacement equipment, a price adjustment or a refund. The appropriate response depends on the facts, agreement and mandatory law; a complete international return is not the default solution.

Opening factory packaging does not automatically prevent a claim for a genuine pre-existing defect, including a defect found in a fan coil unit during unpacking. Evidence and investigation are still required.
