Cold Climate Heat Pump Capacity

Mitsubishi P-Series Hyper-Heat (ducted): Heating Capacity at 5F and Below

The MAX heating capacity the Mitsubishi P-Series Hyper-Heat (ducted) holds as it gets cold, from the AHRI-certified NEEP record (AHRI 211259279), with the maintained-% and a balance-point readout.

MAX Capacity by Temperature

The “will it heat my house at 5F” answer is the MAX at 5F (38,000 BTU/hr), shown next to the rated 47F capacity so you see both. Capacity below -13F is not published for this line, so it is not extrapolated here.

Maintained Capacity at 5F

At 5F the Mitsubishi P-Series Hyper-Heat (ducted) holds 38,000 BTU/hr. That is 95% of its rated 47F capacity (38,000 / 40,000), and 95% of its MAX 47F capacity (38,000 / 40,000). Both are true; the denominator is always stated. NEEP floors its stored percentage to a whole number (95% and 95% respectively); the computed ratio is shown above.

Balance Point & Backup Heat

The balance point is where this model's declining capacity curve crosses the load line, which runs from zero at 65F to your full design load at the design temperature. Enter your own design heat load in the calculator below for your numbers. This is a readout, not a substitute for a Manual-J load calculation.

Capacity and COP transcribed from the AHRI-certified NEEP cold-climate air-source heat pump database, pinned to AHRI certificate 211259279 for outdoor unit PUZ-HA36NKA: NEEP ccASHP record, accessed 2026-07-11. The manufacturer engineering data or a Manual-J by an HVAC pro has the final say.

The benchmark cold-climate ducted unit: it holds 38,000 BTU/hr at 5F, 95% of its 40,000 rated capacity at 47F, and still puts out 30,400 down to -13F. Mitsubishi markets the line as 100% capacity at 5F, but the AHRI-certified NEEP record prints 95%, which is the honest published number.
