R-407C vs. R-22: Which One Do You Need?
Both run in overlapping equipment categories here's how they actually differ.
| Feature | R-407C | R-22 (the refrigerant it retrofits) |
|---|---|---|
| GWP (100-yr) | 1,774 | 1,810 |
| ODP | 0 | 0.055 (ozone-depleting) |
| ASHRAE Class | A1 (non-flammable) | A1 (non-flammable) |
| Oil Type | POE (polyolester) required | Mineral oil |
| Availability | Current production | Reclaimed/recycled only |

EPA Section 608 Notice
R-407C purchases require valid EPA Section 608 technician certification on file before checkout. R-407C requires POE oil mineral oil used in the original R-22 system must be fully drained and replaced during a retrofit, and POE oil is hygroscopic, requiring careful moisture control during service. R-407C is classified ASHRAE A1 (non-flammable, lower toxicity). Note that R-407C's GWP exceeds the 700-GWP threshold for new residential AC equipment under current EPA rules, so it is used for servicing existing systems, not new residential installs.

What Every Technician Should Know About R-407C
The refrigerant that let existing R-22 equipment keep running once R-22 production began winding down, still one of the most common retrofit jobs in the field.
Why R-407C Requires an Oil Changeover
Unlike R-22, which runs on mineral oil, R-407C requires POE (polyolester) oil, meaning a proper retrofit involves fully draining the system's original mineral oil and replacing it with the correct POE oil before charging. Skipping or shortcutting this step is one of the most common causes of a failed R-407C retrofit.
Temperature Glide and Charging R-407C Correctly
As a zeotropic blend of R-32, R-125, and R-134a, R-407C exhibits meaningful temperature glide roughly 7 to 11°F between its bubble and dew points. Using bubble point for liquid-line subcooling and dew point for suction-line superheat is essential; treating R-407C like a single-component refrigerant during charging leads to an inaccurate charge.
R-407C's Role as R-22 Supply Shrinks
As reclaimed R-22 supply continues to shrink and its pricing climbs, R-407C offers operators a currently-produced alternative for keeping older equipment in service, buying time before a full system replacement becomes the more economical choice.
Frequently Asked Questions
Not quite a simple drop-in R-407C requires switching from mineral oil to POE oil and installing an HFC-compatible filter drier, though it does match R-22's pressure envelope closely.
R-407C isn't compatible with the mineral oil used in R-22 systems; POE oil is required for proper lubrication and oil return, so a full oil changeover is part of any retrofit.
Temperature glide is the difference between a blend's liquid (bubble point) and vapor (dew point) saturation temperatures at a given pressure. R-407C's three-component blend causes roughly 7–11°F of glide, which affects how subcooling and superheat should be measured.
Yes. Federal EPA Section 608 rules require valid technician certification on file before purchase.
No. R-407C is ASHRAE-classified A1, non-flammable and lower toxicity.
No, its GWP of 1,774 exceeds the 700-GWP threshold for new residential AC under current EPA rules. It's used to service existing systems, not new installs.
