Refund policy

Last updated: October 28, 2026

Thank you for shopping with KOOLIN. Because our products include compressed refrigerants and specialized gases, returns, exchanges, and refunds are subject to strict safety and inspection standards outlined below.

1. 14-Day Return & Exchange Policy

We offer a 14-day return and exchange policy from the date of confirmed delivery.

Eligible Return Window: Return or exchange requests must be initiated within 14 calendar days of receiving your order.
Product Condition Standards: Returned cylinders must remain 100% factory-sealed, complete, undamaged, and show zero signs of use, valve opening, puncture, or tampering. Cylinders with broken security seals, scratches, or altered serial numbers are not eligible for return.
Warehouse Inspection & Refund: Once the returned goods arrive at our regional US warehouse, our technicians will conduct a mandatory inspection. Upon successful verification of product integrity, your refund or replacement will be processed promptly. Refunds will be credited back to your original payment method.
Return Shipping Costs: All return shipping postage, carrier freight, DOT Hazmat transit surcharges, and related handling costs incurred during the return or exchange process are the sole responsibility of the buyer.

2. Damaged, Leaking, or Incorrect Shipments

Please inspect your delivery immediately upon arrival. If your cylinder arrived visibly damaged, compromised, leaking, or different from what you ordered, contact us immediately at support@koolin.app with your order number and clear photographic/video evidence. KOOLIN will arrange a replacement or issue a full refund at no extra cost to you.

3. Return Authorization (RMA) Requirement

Do not ship any merchandise back without contacting us first. Unauthorized returns cannot be accepted at our warehouse facilities. Upon review and approval of your return request, we will provide you with official Return Merchandise Authorization (RMA) instructions and designated return warehouse address details.

4. Ineligible Return Items

Unless required by applicable consumer law, items are not eligible for return or refund under the following conditions:

Products returned beyond the 14-calendar-day window;
Opened, tapped, partially used, transferred, or modified refrigerant cylinders;
Products damaged due to customer misuse, improper handling, or unsuitable storage;
Items returned without prior RMA authorization.

5. Order Cancellation

If you need to cancel an order, please email us immediately. We can cancel and fully refund orders before they have been processed or dispatched by our warehouse. Once an order has entered fulfillment or transit, it cannot be canceled and must follow this 14-Day Return Policy.
