Frequently Asked Questions

Answers to common questions about ordering commercial HVAC from China: MOQ, payment terms, delivery time, warranty, certification and installation support.

HomeFrequently Asked Questions
What is your minimum order quantity (MOQ)?

For standard models the MOQ is typically 1 unit/set — we welcome trial orders from first-time buyers. Project quantities receive tiered pricing; OEM production runs have model-specific minimums that we confirm at quotation.

Which payment terms do you accept?

Commonly T/T (bank transfer) with a deposit and balance before shipment; L/C at sight is available for larger orders. Exact terms are agreed per order and stated clearly on the proforma invoice.

How long is the delivery time?

In-stock standard models ship quickly; produced-to-order equipment typically requires 15–30 days depending on model and quantity, plus sea freight. Every quotation states the current lead time.

What warranty do you provide?

Standard warranty is 12 months from commissioning (up to 18 months from shipment), covering manufacturing defects with spare parts support. Extended warranty and spare-parts kits can be included in project offers.

Are your units certified for my country?

Our VRF and AC ranges carry SASO (Saudi Arabia), ESMA (UAE), Kuwait MEW, EUROVENT, SGS and CE certificates — see the Certificates page. For other markets, certification can be arranged per project.

Do you supply 60 Hz / T3 tropical versions?

Yes. Most ranges offer 60 Hz electrical versions and T3 high-ambient designs that maintain cooling output in 50 °C+ summers — specify your grid and climate when you inquire.

Can you help with system design?

Yes, free of charge with your inquiry: send architectural plans or room dimensions and our engineers return equipment selection, capacity calculations and piping/electrical schematics.

Do you offer installation support?

We provide installation drawings, remote video supervision, and — for larger projects — on-site commissioning engineers and installation training for your local team.

Can you produce under our brand (OEM/ODM)?

Yes. Chillers, fan coil units, AHUs and light commercial units can be manufactured to your brand, colours and packaging in our own factory under ISO9001 quality management.

How do you pack equipment for sea freight?

Carton + wooden case/crate or pallets engineered for container transport and transshipment handling. Accessories are consolidated into the same shipment so nothing arrives missing.
