伊朗采购需求：空调，分体空调

I'm interested in placing an order for one container of split air conditioners that are T3 rated and designed solely for cooling purposes. Specifically, I would like to know the pricing for the various BTU capacities I need: 12,000 BTU, 24,000 BTU, and 30,000 BTU. Please provide the cost for each size individually, as I'm considering a mix of these models in the container. Additionally, could you let me know the lead time for this order, as well as any available discounts for purchasing in bulk? I'm looking for a reliable supplier, so any information regarding warranty and after-sales support would also be appreciated. Looking forward to your prompt response!
