You can depend on Clifford's HVAC for all of your home and commerical HVAC needs.
If your HVAC system is more than a few years old, chances are it uses R-410A refrigerant — the industry standard for years. But as efficiency standards rise and environmental regulations tighten, new refrigerants are hitting the market. These changes can leave homeowners wondering what it all means when it’s time for repairs, maintenance, or a system upgrade.
Here’s a simple guide to understanding R-410A vs. newer refrigerants and how these changes could affect your comfort, efficiency, and future HVAC decisions.
Refrigerant is the “lifeblood” of your HVAC system. It absorbs heat from inside your home and releases it outdoors, keeping your home cool in the summer (and in some systems, warm in the winter). Without the right type and amount of refrigerant, your system can’t function properly.
R-410A replaced the older R-22 refrigerant (also known as Freon) when R-22 was phased out in 2020.
Benefits of R-410A:
More efficient and better for system performance
Safer for the ozone layer than older refrigerants
Widely available and supported
Drawbacks of R-410A:
Still contributes to greenhouse gas emissions
Will eventually be phased down under new EPA guidelines
To meet environmental standards, manufacturers are moving toward next-generation refrigerants like R-32 and R-454B.
Advantages of Newer Refrigerants:
Lower environmental impact (reduced global warming potential)
Increased energy efficiency for new HVAC systems
Designed to work with advanced, high-efficiency units
What to Know:
These refrigerants are not compatible with older systems. If your system uses R-410A, it can’t simply be “topped off” with the newer options.
Over time, systems using R-410A will be less common, which could make repairs more expensive.
If your system is in good shape and running well, there’s no need to panic. R-410A will still be available for years to come. However, if you’re considering a new system, it’s smart to talk with your HVAC technician about models that use newer refrigerants.
Upgrading now can mean:
Lower energy bills thanks to higher efficiency
Future-proofing your home for upcoming regulatory changes
Access to rebates and incentives for eco-friendly systems
Your system needs frequent refrigerant refills
Cooling performance has dropped, even after maintenance
You’re facing costly compressor or coil repairs
Your unit is over 10–12 years old and nearing replacement
