R-32 vs. R-454B: What Central Florida Homeowners Need to Know About New AC Refrigerants

R-32 vs. R-454B: What’s the Difference?

If you're shopping for a new air conditioning system in Central Florida, you may notice something different: many new systems no longer use R-410A.

The HVAC industry is transitioning toward refrigerants with lower global warming potential (GWP), including R-32 and R-454B. Both are classified as A2L refrigerants, meaning they have lower flammability than refrigerants in higher-flammability classifications and require equipment specifically designed for their use.

What Is R-32?

R-32 is a single-component refrigerant already used in HVAC equipment around the world. It has a significantly lower GWP than R-410A and can be recovered and handled as a single refrigerant rather than a blend.

What Is R-454B?

R-454B is a refrigerant blend developed as another lower-GWP alternative to R-410A. Several HVAC manufacturers have adopted R-454B for their next generation of residential equipment.

Is R-32 Better Than R-454B?

There isn't one answer for every homeowner.

The refrigerant is only one part of an HVAC system. Equipment quality, efficiency, proper sizing, ductwork, airflow, humidity control, installation practices, warranty support, and future serviceability can matter far more than the refrigerant printed on the equipment label.

At Savage Heating & Air, we don't believe homeowners should buy an AC system based on a refrigerant name alone.

We evaluate the entire home and recommend equipment based on what actually makes sense for the homeowner.
