Frequently asked questions
Buying
Do I need EPA certification to buy refrigerant here?
For restricted refrigerants, yes: EPA Section 608, or Section 609 for motor-vehicle A/C work. Placing an order confirms you are permitted to buy it. See the compliance policy.
Is the refrigerant virgin or reclaimed?
Each listing says so in the title and description. Most of our cylinders are virgin, factory-sealed product; reclaimed lines are clearly labelled.
Are the water heaters and boilers new?
Yes — every appliance is factory-new in the manufacturer's sealed carton and carries the full manufacturer warranty.
Natural gas or propane — how do I choose?
Match the fuel your site is plumbed for. Model numbers ending in N are natural gas and those ending in P are propane (for example RU199iN vs RU199iP). If you're unsure, email us the model on your current unit.
Can I mix two refrigerants, or top up one with another?
No. A mixture behaves like neither gas and no pressure–temperature chart describes it. Recover the charge and refill with the refrigerant on the equipment data plate.
Shipping
How much is shipping?
It's free on every order within the United States, with no minimum.
How long will my order take?
We dispatch within 1 business day (Mon–Fri). Parcel delivery takes 1–4 business days; freight and pallets are delivered by appointment.
Why does the carrier's weight differ from the product weight?
Carrier weight includes the cylinder or appliance itself plus packaging. Refrigerant weights on our pages are net fill weight.
Can I ship one order to several addresses?
No — please place one order per delivery address so each shipment has its own tracking.
Do you ship outside the United States?
Not at the moment. We ship to U.S. addresses only.
After you order
Can I return something I don't need?
Yes, within 90 days if it's unopened and factory-sealed, with no restocking fee. Opened refrigerant and installed appliances can't be returned. See returns & refunds.
My order arrived damaged. What now?
Photograph it and email us with your order number within 72 hours. We'll replace it or refund you — usually without you shipping it back.
How long does a refund take?
We inspect approved returns within 72 hours of arrival and refund within 7 business days to your original payment method.
What does the warranty cover?
Appliances carry the full manufacturer warranty. Refrigerant, cylinders and accessories have our 30-day defect cover. See the warranty policy.
Payment
Is my card safe?
Yes. Payment is taken on Stripe's hosted checkout — card details go straight to Stripe and never reach our servers.
