Frequently asked questions
Can I return or exchange gas cylinders?
For safety and handling reasons, opened, used, or installed gas cylinders cannot be returned or exchanged. If your order arrives damaged, defective, or incorrect, please contact us with photos and order details so we can review the issue and provide a suitable solution.
How fast and reliable is shipping?
We usually ship within 24 hours (Mon–Fri) from our U.S. warehouse via FedEx, with delivery in 2–5 business days. Every cylinder is securely packaged for safe transport. Should anything happen in transit, our team will be ready to assist right away.
Why does the shipping label weight differ from the product weight I purchased?
The weight shown on the shipping label may be a pre-declared or billing weight used by the carrier for shipment processing. It may not always match the actual net weight of the refrigerant cylinder.
Please rest assured that this does not affect the product you receive and does not require any additional payment. The cylinder you receive will match the product weight listed on the product page.
What payment methods do you accept?
We accept all major credit and debit cards through Shopify’s secure checkout system. Your payment details are encrypted and protected, so you can shop with confidence knowing your information is safe.
How should I handle gas cylinders safely?
To keep everything safe, store cylinders upright in a cool, ventilated place and away from direct heat. The included instructions cover best practices, and if you ever feel unsure, our support team is happy to guide you.
