You may have heard that certain HVAC refrigerants are being phased out. Understanding these changes is important when repairing or replacing your system. The last thing you want is to invest in equipment that uses a refrigerant no longer supported. Working with an experienced company like M&S Air Conditioning ensures your home stays compliant with current standards and upcoming regulations.

What Is the American Innovation and Manufacturing Act (AIM Act)?

The AIM Act is a federal law passed in 2020 that requires an 85 percent reduction in hydrofluorocarbon (HFC) production and consumption by 2036. HFCs are high global-warming-potential refrigerants commonly used in older HVAC systems. The AIM Act supports new refrigerant technologies with lower environmental impact, including A2L refrigerants such as R-32 and R-454B.

Certain Refrigerants Are No Longer Manufactured

You do not need to know the chemistry behind refrigerants, but you should know that many older types are no longer produced. If your HVAC system still relies on a phased-out refrigerant, repairs can become more complicated and expensive due to limited supplies.

The EPA has restricted or is phasing down the use of the following refrigerants in many types of new HVAC equipment:

  • R-22
  • R-142b
  • R-11
  • R-12
  • R-410A
  • R-134a
  • R-404A
  • R-407C
  • R-123
  • R-507A

You May Pay Higher Repair Costs for Phased-Out Refrigerants

If your system still uses a phased-out refrigerant, repairs involving refrigerant recharges will cost more. Because these refrigerants must come from recycled or reclaimed supplies, they are increasingly rare and expensive. A repair that was once affordable may now be several times the cost. At a certain point, upgrading your system makes more financial sense than continuing to repair an outdated unit.

Systems Using Outdated Refrigerants Usually Require Faster Replacement

HVAC systems designed for older refrigerants often experience more frequent breakdowns due to age, pressure differences, and wear. Newer refrigerants operate more efficiently and typically pair with improved system components, reducing strain over time.

New Refrigerants Often Require Updated Equipment

Refrigerants like R-454B and R-32 cannot be used in older systems. Their pressure levels and chemical properties require specific coils, valves, compressors, and safety features. Retrofitting most older systems is not recommended and can lead to performance issues or safety concerns. In many cases, replacing the system with one designed for A2L refrigerants is the safest and most cost-effective option.

Warranties and Phased-Out Refrigerants

You must use the correct refrigerant type for your HVAC system. Installing the wrong refrigerant can void your manufacturer warranty. This can leave you paying out of pocket for failures that would otherwise be covered. Having a technician from M&S Air Conditioning verify compatibility protects your system and warranty coverage.

Insurance and Phased-Out Refrigerants

Some insurance providers are cautious about covering older systems that use discontinued refrigerants. These units are more prone to leaks and failures. Ensuring that your HVAC equipment uses current, compliant refrigerants helps you maintain strong insurance coverage and reduces the risk of claims being denied.

Disposal of Equipment Using Outdated Refrigerants

HVAC systems that contain phased-out refrigerants must be disposed of properly. It is illegal to place them in regular trash. Refrigerant must be professionally recovered and the unit must be taken to an approved recycling facility. M&S Air Conditioning handles this process safely and ensures full compliance with disposal regulations when we replace your system.

Matching Refrigerant Type Is Crucial to Compatibility When Doing Replacements

Never mix refrigerants. Combining incompatible refrigerants or oils can cause chemical reactions, system pressure imbalances, and severe equipment damage, including compressor failure. Only a certified technician should handle refrigerant changes or compatibility assessments.

Are DIY Refrigerant Leak Fixes Safe?

No. Refrigerant leaks require professional attention. DIY sealants or repairs can damage your system, violate EPA regulations, and expose you to harmful chemicals. Leaks need to be diagnosed and repaired with proper equipment and training.

What to Do When You Suspect Low or Leaky Refrigerant?

If you believe your system is leaking refrigerant, turn it off and call us immediately. We will inspect the system, locate the leak, and determine the best repair. Small cracks may be sealed, but larger or corroded line sets may require replacement. Our technicians will evaluate the entire refrigerant circuit to prevent future leaks.

  • Prevents accidental system damage
  • Protects your warranty
  • Avoids unsafe chemical reactions
  • Maintains correct operating pressures
  • Reduces risk of major breakdowns
  • Ensures safe and legal refrigerant handling
