Refrigerant is the working fluid that lets an air conditioner, heat pump, or refrigeration system move heat from one place to another. It's what makes cooling possible in the first place. Our refrigerant selection covers commonly serviced systems in residential and commercial environments, from routine recharges to full system service. Refrigerant sales are intended for HVAC professionals and experienced, appropriately certified users.
| Refrigerant | Type | Safety class | GWP (approx.) | Typical use |
|---|---|---|---|---|
| R-410A | HFC blend (R-32/R-125) | A1, non-flammable | ~2,088 | Residential/commercial AC & heat pumps installed 2010–2024 |
| R-32 | Single-component HFC | A2L, mildly flammable | ~675 | Newer AC and heat pump systems, mini splits |
| R-454B | HFC blend (R-32/R-1234yf) | A2L, mildly flammable | ~466 | Current-generation residential AC & heat pumps |
| R-22 | HCFC (legacy) | A1, non-flammable | High ODP, phased out | Servicing existing pre-2010 systems only, no new production |
Under the EPA's AIM Act, R-410A production for new residential AC and heat pump equipment stopped as of January 1, 2025, pushing the market toward lower-GWP alternatives like R-32 and R-454B.
These newer refrigerants are classified A2L (mildly flammable) rather than A1 (non-flammable), which means matched equipment, handling procedures, and service tools differ from older systems.
Existing R-410A systems can still be serviced using recovered or reclaimed R-410A, but it isn't a drop-in replacement for R-32 or R-454B, or vice versa. The refrigerant must match what the equipment was designed and charged for.
These are single-use cylinders sold pre-filled with refrigerant. They're not designed to be refilled, doing so is a compliance violation. Once empty, the cylinder should be depressurized, punctured, and scrapped.
Built for repeated use, these cylinders go back to a distributor for refilling rather than being disposed of. Each carries a DOT pressure rating stamped on the shoulder (e.g., DOT-4BA300 for R-22, DOT-4BA400 for R-410A), and must be hydrostatically retested and recertified every 5 years.
Recovery cylinders are used only to hold refrigerant removed from a system during service, never as a stand-in for a virgin-refrigerant cylinder. They're typically gray with a yellow shoulder, and should never be filled beyond 80% of rated water capacity to leave room for thermal expansion.
Cylinders should always be transported upright and secured, never rolled on their base or laid on their side. Keep them away from heat sources that could raise internal pressure beyond safe limits.
Refrigerant type must match the system's original specification exactly. Before ordering, confirm:
Mixing or substituting refrigerants (e.g., topping off an R-410A system with R-32) can damage components, misrepresent system pressures, and void the manufacturer's warranty.
Refrigerant cylinders should be stored upright, in a cool, ventilated area, away from heat sources and direct sunlight. Handling requires appropriate PPE (gloves, eye protection) and leak-detection equipment. Under EPA Section 608 of the Clean Air Act, refrigerant may not be vented to the atmosphere during service. It must be recovered into a certified recovery tank and, where applicable, processed by a certified reclaimer. Regulations and certification requirements vary by refrigerant type and jurisdiction, so verify current requirements before purchasing or servicing.
Refrigerant is available in a range of cylinder sizes for both single recharges and stocking up for regular service work, with bulk pricing available for contractors ordering in volume.

Common HVAC refrigerants such as R-410A and related refrigerant gases used for air conditioning, heat pumps, and cooling systems, suited to professional service and recharge applications.
Refrigerant type must match the system's original specification: mixing or substituting different refrigerants (e.g., R-410A vs. R-32) can damage components and void warranties. Always check the equipment's manufacturer label or service manual.
Refrigerants sold are intended to meet industry standards and regulatory requirements for HVAC servicing, but availability and regulatory status (e.g., phase-outs) vary by region. Verify local guidelines before purchase.
No, refrigerant is essential for transferring heat. A system without it won't cool, and running it without proper charge can damage components.
Upright, in a cool, ventilated area away from heat sources, using protective equipment and leak-detection tools during handling.
Yes. R-22 has been phased out of production; R-410A is being replaced in new equipment by lower-GWP alternatives like R-32 and R-454B, though existing R-410A systems can still be serviced where allowed.
Depending on the refrigerant type and applicable regulations, purchasing certain refrigerants may require technician certification (e.g., EPA Section 608 in the US). Requirements vary by refrigerant and jurisdiction, confirm current rules before ordering.
Virgin refrigerant is newly manufactured and never used; reclaimed refrigerant has been recovered from service and reprocessed by a certified reclaimer to meet the same purity specification. Some warranties require virgin refrigerant only.
