AI-Powered supplier vetting

SummaryECOAIR is an HVAC supplier with more than 20 years of stated technical experience and capabilities spanning design, customization, manufacturing, installation, and after-sales maintenance. It provides OEM and ODM services, supports extensive customization, and has quality-control procedures covering assurance, traceability, complaint handling, and inspection. Reported production includes 100,000 heat exchanger coils and 1,000 air-handling-unit sets, with three production lines and export coverage across multiple regions. Lead time is one month during off-peak periods and two to three months during peak periods. The supplier reports ISO9001:2015 certification and one national science and technology progress award. However, it has no available SDK, no new product in the past year, no overseas warehouse, showroom, agent, or branch, and no offline trade-show participation. Financial records are identified by year, but no substantive financial performance details are provided.

Supplier typeECOAIR is presented as an HVAC enterprise with over 20 years of technical experience, offering professional design, selection, program guidance, construction, maintenance, OEM, ODM, and manufacturing services. Its product and service scope indicates a manufacturer with integrated project and customization capabilities.

CertificationsThe supplier reports one national science and technology progress award and an ISO9001:2015 certificate. These are explicit credentials supporting technical recognition and quality-system certification.

After-Sales capabilityECOAIR explicitly provides after-sales maintenance and reports written, followed procedures for service-capability assessment, corrective and preventive actions, and complaint handling. Quality-control records and product traceability further support structured post-sale issue management.

Production capacityProduction evidence includes three production lines, cutting, pipe-bending, and assembly equipment, reported output of 100,000 heat exchanger coils and 1,000 air-handling-unit sets, and peak-season fulfillment of two to three months. A stated weakness is that the factory does not continuously reconcile quantities for every batch or mass-production run.

Customization capabilityECOAIR explicitly supports customization from samples and designs, minor and flexible customization, and full customization, while also offering OEM and ODM services. This directly demonstrates a broad ability to adapt products to customer requirements.

Product Q&A

Q:What is the minimum order quantity?
