Is R22 Illegal? Understanding the Refrigerant Phase-Out
Have you heard that R22 is illegal?
Let’s clear up any confusion about R22 phase-out and its legal status. This article explains what the phase-out means for HVAC systems and how it affects homeowners heatpump, mini-split, or central AC repair.
What Should You Do if Your HVAC System Uses R22?
If your HVAC system uses R22, you have a few options:
- Continue using R22: As long as your system is functioning properly, you can still use existing supplies.
- Retrofit your system: Modify your system to use more eco-friendly refrigerants.
- Replace your system: Consider upgrading to a new system with modern refrigerants.
For personalized advice, contact a local HVAC professional who can recommend the best course of action.
When Should You Avoid Refilling Your System with R22?
If your air conditioner or heat pump uses R22 refrigerant, there are a few situations where refilling might not be the best option. Here’s when you should consider other solutions:
- If your system has multiple Freon leaks that are difficult to fix.
- If the leak is in the evaporator and your system is over 20 years old.
- If the condenser has a leak and your evaporator coils show signs of rust.
- If your compressor has experienced a burn-out, indicating deeper issues.
- If your evaporator was designed for a fixed orifice metering device and is leaking.
In these cases, it might be worth consulting with a local HVAC expert who can help you evaluate the situation and suggest the most cost-effective and efficient solution.
What is R22?
R22, also known as HCFC-22 or Freon-22, is a refrigerant used in air conditioners and heat pumps. It is being phased out due to its harmful effects on the ozone layer.
Who Makes R22 Freon?
R22 Freon is produced by Chemours, a company that owns the "Freon" brand. Freon refers to specific halocarbon products such as R-12, R-22, and others used in cooling systems.
Is R22 Freon Refrigerant Really Illegal?
No, R22 is not illegal for residential and light commercial systems (with a refrigerant charge of 50 lbs or less). You can continue using it in your current HVAC system.
R22 Phase-Out Explained
The Environmental Protection Agency (EPA) has been phasing out R22 as part of efforts to protect the environment. However, homeowners can still use R22 for maintenance in existing systems.

The EPA R22 "Phase Out": What's Changed?
Under the Clean Air Act, the U.S. stopped the production and importation of R22 on January 1, 2020. But existing supplies can still be used for system repairs.
| Change | Impact |
|---|---|
| R22 production stopped | No new R22 can be manufactured in the U.S. after January 1, 2020. |
| Existing R22 supplies | Can still be used to service existing equipment. |
| Service for old systems | Maintenance continues for systems that use R22. |
What Does "R22 Phased Out" Really Mean?
It means that no new production or import of R22 refrigerant is allowed, but existing systems can still use the remaining stock. This change mainly affects new systems, not older systems already in use.
Freon and Refrigeration Leaks
Refrigeration Leaks are challenging to detect and require EPA 608 certified technician for repair.
Keep in mind that Refrigerant Leak Repair require several "surgical" percision steps in such a case it is not a DIY project
