1. What this Warranty Covers

This Warranty Policy applies to eligible products purchased directly from Hon&Guan through honguan.com, unless the product page, manual, order confirmation, or a separate written agreement provides different terms.

Subject to the terms below, Hon&Guan warrants to the original purchaser that the covered product will be free from defects in materials and workmanship during the applicable warranty period when used normally and in accordance with the product instructions.

This commercial warranty does not remove or reduce any mandatory consumer rights or statutory remedies available under applicable law. If a separate written quotation, project agreement, or product-specific warranty applies to your order, that document controls to the extent it expressly addresses the same subject differently.

2. Warranty Period

Unless a product page, product manual, or order document states a different period, the warranty period for covered fans, controllers, and electronic products is 12 months from the original purchase date.

The warranty period begins on the date shown on the original order or other valid proof of purchase. A replacement product or repaired product does not automatically create a new full warranty period; its remaining coverage will be confirmed in the resolution provided for the claim.

Different products, accessories, consumables, bundles, and project orders may have different coverage. The applicable period should be confirmed from the product page, manual, order document, or written support response.

3. What We May Do for an Approved Claim

After reviewing a valid claim, Hon&Guan may, depending on the circumstances and applicable law:

• repair the product;
• replace the product with the same model or an equivalent product;
• provide the parts needed to correct the defect where appropriate; or
• provide a full or partial refund, credit, or other remedy where repair or replacement is not reasonably available.

We will determine the appropriate remedy after considering the defect, product availability, safety, shipping conditions, repair feasibility, and your applicable legal rights. A remedy offered under this commercial warranty does not limit a remedy that cannot lawfully be excluded.

4. Products and Situations Covered

Examples of issues that may be covered include a manufacturing defect in materials, workmanship, or product performance that appears during normal use within the applicable warranty period.

To assess a claim, we may need to confirm the model, serial number, installation environment, voltage, controller or accessory configuration, maintenance history, and the symptoms of the issue.

Visible damage, missing parts, or an incorrect product should be reported as soon as possible after delivery and should normally be handled under the Returns & Refunds Policy or the delivery-damage process. Reporting a delivery issue promptly helps us preserve evidence and arrange the correct remedy.

5. What This Warranty Does Not Cover

To the extent permitted by applicable law, this commercial warranty does not cover:

• normal wear, expected service life, cosmetic changes, noise or performance changes caused by ordinary use, or consumables that are designed to be replaced;
• damage caused by incorrect voltage, wiring, power supply, installation, assembly, maintenance, storage, transportation after delivery, or use outside the product instructions;
• damage caused by accident, misuse, abuse, neglect, modification, unauthorized repair, alteration, impact, water or chemical exposure, corrosion, blockage, contamination, fire, flood, storm, or another external event;
• damage caused by operating the product outside its rated environment, capacity, temperature, humidity, duct configuration, airflow conditions, or other published limits;
• products used for an unlawful, unsafe, or unapproved application, or used in a way that violates applicable safety, electrical, building, export-control, or other requirements;
• products purchased from an unauthorized source where the purchase cannot be verified;
• loss of or damage to a product that was sent to an address not provided or approved by Hon&Guan; or
• installation, removal, access, labor, project redesign, lost production, loss of use, or other indirect project costs, unless applicable law or a written agreement requires otherwise.

An exclusion does not apply where applicable law does not permit that exclusion or where the issue is unrelated to the excluded circumstance.

6. How to Submit a Warranty Claim

Contact support@honguan.com before sending a product back. Please include, where available:

• your name and contact details;
• order number, receipt, invoice, or other proof of purchase;
• product model, serial number, and purchase channel;
• a clear description of the problem and when it first occurred;
• photographs or video showing the issue;
• installation, voltage, controller, duct, and operating information relevant to the problem; and
• the country or region where the product is located.

Do not send a product to the company or business address shown on the website unless we give you a return or service address in writing. Do not disassemble or modify a product to investigate a problem if doing so may create a safety risk or affect the assessment of the claim.

We may ask for reasonable additional information, troubleshooting steps, or a return inspection. A return authorization or case reference helps us track the shipment; it does not remove any mandatory legal right that can be exercised by a clear notice under applicable law.

7. Shipping and Service Costs

For an approved claim involving a defect covered by this Warranty Policy, Hon&Guan will provide the applicable return and service instructions. For an approved claim involving a defect covered by this Warranty Policy, Hon&Guan covers reasonable necessary return shipping and the standard shipping cost for the repaired or replacement product.

If inspection shows no covered defect, or shows damage caused by misuse, incorrect installation, unauthorized modification, or another excluded circumstance, we may ask the customer to pay reasonable diagnostic, return, storage, or shipping costs before returning the product. We will explain any such charge before it is incurred where practicable.

We do not cover the cost of installing, removing, accessing, reinstalling, or modifying a product unless a written agreement or applicable law requires it.

8. Purchases from Retailers, Marketplaces, and Distributors

If you purchased through a retailer, marketplace, distributor, reseller, contractor, or other third party, contact that seller first because its order, return, and after-sales process may apply.

Hon&Guan may still help identify available product support or a manufacturer warranty process. We do not treat a third-party purchase as a direct honguan.com order, and we do not promise that every third-party channel is covered by the same commercial warranty.

9. Wholesale, Project, and Custom Orders

Wholesale, project, reseller, made-to-specification, and custom orders may be governed by a written quotation, purchase order, or project agreement. That document should state the warranty period, inspection and acceptance process, defect notice period, shipping responsibility, spare parts, technical support, installation responsibility, and any performance criteria.

Buying multiple units does not by itself remove consumer status or mandatory consumer rights. A business or project agreement controls only to the extent it validly applies to the transaction and expressly addresses the same warranty subject.

10. No Automatic Performance Guarantee

This Warranty Policy addresses defects in the product. It does not guarantee that a product or configuration will achieve a particular airflow, pressure, noise, energy, air-quality, building, crop, or project result unless that result is expressly stated in an accepted written specification or agreement.

Product selection, installation, electrical work, duct design, maintenance, and project compliance remain subject to the product instructions and applicable requirements. Technical guidance from Hon&Guan does not replace an appropriate on-site assessment or qualified professional design where one is required.
