Frequently asked questions
Yes for most products. Refrigerants are sold to technicians holding EPA Section 608 certification, and to businesses buying for resale or for use by certified technicians. We may ask you to supply proof of certification before an order is dispatched. Solstice EZ Flush and other non-refrigerant products are not subject to this restriction.
Shipping is free to all 48 contiguous states, on single cylinders and full pallets alike. In-stock orders placed before 2:00pm CT on a business day are dispatched the same day. Single cylinders typically arrive in 2–5 business days and pallet freight in 3–7 business days. Alaska, Hawaii and international destinations are quoted separately.
Every cylinder is factory sealed with a tamper-evident cap and supplied at its stated net weight. Product is virgin grade, meeting the AHRI 700 purity specification, in DOT-specification disposable cylinders. Lot markings and hazard labels are intact so the cylinder can be traced back to its batch.
Unopened, factory-sealed cylinders can be returned within 30 days with an RMA number issued by us. Opened, part-used or broken-seal cylinders cannot be accepted, because their contents and purity cannot be verified. A restocking fee applies to change-of-mind returns, and is waived when the return is our error. Full details are on our Refund and Returns Policy page.
