HCFCs (Hydrochlorofluorocarbons)
HCFCs (hydrochlorofluorocarbons) are man-made compounds once used widely as refrigerants, solvents, and foam-blowing agents. They are less damaging to the ozone layer than CFCs but still have ozone-depleting potential and contribute to climate change. Their production and use are being phased out under the Montreal Protocol.
💡 Key Takeaways
- ✓HCFCs (hydrochlorofluorocarbons) are man-made compounds once used widely as refrigerants, solvents, and foam-blowing agents. They are less damaging to the ozone layer than CFCs but still have ozone-depleting potential and contribute to climate change. Their production and use are being phased out under the Montreal Protocol.
- ✓HCFC-22 (R-22) was the most common HVAC refrigerant in this group.
- ✓Phase-out timelines vary by region but continue to restrict production.
- ✓Proper recovery and disposal prevent atmospheric release.

Definition
HCFCs (hydrochlorofluorocarbons) are man-made compounds once used widely as refrigerants, solvents, and foam-blowing agents. They are less damaging to the ozone layer than CFCs but still have ozone-depleting potential and contribute to climate change. Their production and use are being phased out under the Montreal Protocol.
Why are HCFCs being phased out?
They deplete the ozone layer and contribute to climate change, so international agreements restrict their use.

Quick Facts
How HCFCs (Hydrochlorofluorocarbons) Works
HCFCs are being phased out to protect the ozone layer.
Real-World Application
Older HVAC systems may still use HCFC-22 (R-22), and owners often upgrade or retrofit to newer refrigerants during replacement.
Pro Tip
When servicing legacy systems, use certified technicians who can safely recover and handle HCFC refrigerants.
“When servicing legacy systems, use certified technicians who can safely recover and handle HCFC refrigerants.”
Important Things to Keep in Mind
- HCFC-22 (R-22) was the most common HVAC refrigerant in this group.
- Phase-out timelines vary by region but continue to restrict production.
- Proper recovery and disposal prevent atmospheric release.
Did You Know?
Replacing HCFC systems often improves efficiency along with reducing environmental impact.
FAQ
Is R-22 the same as HCFC?
R-22 is an HCFC refrigerant and one of the most common in older systems.
Can HCFC systems still be serviced?
Yes, but refrigerant availability is limited and recovery is required.
What should I do with an old HCFC system?
Consider upgrading to a modern system with lower-impact refrigerants.
