New heat pump models

Since 2025, new heat pumps are made with R-454B or R-32 refrigerant instead of R-410A, which is being phased down. Here is that switch, and the newest certified models of the size class you pick.

Covers heat pumps sold new today (R-454B and R-32 refrigerant). See older R-410A models · Updated

The refrigerant switchIn the newest certifications, R-410A is down to 0%. The oldest certifications still listed were almost all R-410A.

Each bar: 500,000 AHRI certifications in a row. AHRI numbers rise over time, so they stand in for dates, which AHRI does not publish. Source: AHRI directory.

What the switch means

R-454B and R-32 warm the planet far less than R-410A if they leak. Heat pumps already installed with R-410A can still be serviced; the phase-down limits how much new R-410A is made. The two kinds use different parts, so they are listed separately here.
