Refrigerant Buyer's Guide
Which refrigerant do you need?
Start with what you're servicing. A car, truck, or fleet vehicle uses automotive refrigerant. A home or commercial AC system uses HVAC refrigerant. The two are never interchangeable, and charging a system with the wrong one can damage it.
By application
- Vehicle built 2021 or later: R-1234yf. It's the current automotive standard and required on most new vehicle AC systems.
- Older vehicle (pre-2021): R-134a. Most cars and light trucks built before the R-1234yf transition still run on it.
- Existing residential or light commercial AC: R-410A. Still the most common charge in installed systems.
- New residential AC equipment: R-454B. The lower-GWP A2L replacement for R-410A in new equipment.
- Older AC unit installed before 2010: R-22. Supply is limited and pricing reflects it ā a system upgrade is often the better long-term fix.
- Commercial refrigeration: R-404A, R-407A, R-407C, or R-448A, depending on what the equipment manufacturer specifies for that unit.
Not sure which one your system takes? Check the manufacturer's nameplate on the unit itself ā it lists the exact refrigerant the system is designed for. Always follow the equipment manufacturer's specification.
Automotive vs. HVAC refrigerant
| Category | Automotive | HVAC |
|---|---|---|
| Common types | R-1234yf, R-134a | R-410A, R-454B, R-22, R-407C, R-448A |
| System use | Vehicle AC systems | Residential and commercial AC / refrigeration |
| Purity standard | SAE J2099 | AHRI 700 |
| Typical container | Small cans and cylinders | Cylinders and drums |
R-410A vs. R-32 vs. R-454B
| Refrigerant | GWP | Common use | Safety class |
|---|---|---|---|
| R-410A | 2,088 | Existing residential and commercial AC | A1 (non-flammable) |
| R-32 | 675 | Newer AC systems, lower GWP | A2L (mildly flammable) |
| R-454B | 466 | Next-generation residential AC replacement for R-410A | A2L (mildly flammable) |
A2L refrigerants require equipment designed and rated for A2L use, and handling per the manufacturer's and applicable safety requirements. Some refrigerants require a valid EPA Section 608 certification to purchase, and certain products are restricted in some states ā requirements are noted on each product page.
