This policy explains how to request a return, report a damaged or incorrect product, and receive an approved refund.

Return Window

You must request return authorization within 30 days after delivery. A request made after this period may be declined.

Return Eligibility

To qualify for a standard return, the product must be unused, unopened, in its original packaging, and have the factory seal intact. Proof of purchase is required. Products showing installation, use, tampering, leakage, missing labels, damaged seals, or improper storage are not eligible unless the condition resulted from a verified defect or shipping damage.

Dangerous-Goods Authorization

Refrigerants and pressurized cylinders may be regulated as dangerous goods. Do not mail or ship a return without written authorization, a confirmed return destination, and carrier-compliant instructions from us. Unauthorized returns may be refused and may create safety or legal risks.

How to Request a Return

Email heisen1996@outlook.com with your order number, product name, quantity, reason for the request, and photos when the item is damaged, defective, leaking, or incorrect. If approved, we will provide the next steps.

Damaged, Defective, or Incorrect Products

Inspect the shipment promptly after delivery. Report visible damage, leakage, missing items, or an incorrect product as soon as reasonably possible and retain the product, cylinder, carton, labels, and packing material while the claim is reviewed. Approved claims for defective, transit-damaged, or incorrectly shipped products are not subject to a restocking fee, and we will cover reasonable authorized return costs.

Non-Defect Returns

An approved return caused by customer preference, ordering the wrong compatible product, or another non-defect reason is subject to a 15% restocking fee. The customer is responsible for authorized return shipping and dangerous-goods carrier charges.

Order Cancellations

An order cancelled before shipment is not subject to a restocking fee. A cancellation request is not guaranteed if warehouse processing or carrier tender has already begun.

Inspection and Refund Timing

After an authorized return is received, inspection normally takes 2–5 business days. If approved, the refund is initiated to the original payment method within 1–2 business days. Your bank or payment provider may require an additional 3–10 business days to post the credit. Original expedited shipping and other non-refundable carrier charges are not refunded unless the return resulted from our error or an approved defect claim.

Rejected Returns

A return may be rejected if it was unauthorized, submitted after 30 days, opened, used, altered, missing required packaging or labels, damaged by improper storage or handling, or shipped contrary to the provided dangerous-goods instructions.
