R-410A vs R-22: Key Differences HVAC Professionals Should Know

June 12, 2025

 

As the HVAC industry moves toward more efficient and eco-friendly solutions, R-410A has become the standard replacement for phased-out R-22. Here's a quick comparison to help your business stay compliant and informed:

 

1. Regulatory Compliance

R-22: Banned in new systems; only recycled or reclaimed use allowed.

R-410A: Fully compliant with current U.S. regulations (no ozone depletion).

 

2. System Performance

R-410A runs at higher pressures, offering better energy efficiency and cooling performance than R-22.

Not interchangeable: R-410A systems require different components and lubricants (POE oil vs mineral oil).

 

3. Environmental Impact

R-22: Ozone-depleting and high GWP.

R-410A: Zero ozone impact but still has a high GWP (~2,088), making it a transitional refrigerant.

 

4. Market Availability

R-410A: Widely available and cost-effective.

R-22: Limited and expensive due to production bans.

 

R-410A is the current industry standard for new HVAC systems. While R-22 may still be used for servicing older units, it's being phased out. For long-term sustainability, keep an eye on next-gen refrigerants like R-32 and R-454B.
