What is the SEER2 rating of the Mitsubishi Electric PUZ-HA36NKA?

The Mitsubishi Electric PUZ-HA36NKA is rated at up to 20.0 SEER2 and 13.0 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 11 certified matchups SEER2 ranges from 15.3-20.0.

Is the Mitsubishi Electric PUZ-HA36NKA good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 42,000 BTU/h at 5°F with a COP of 2.01, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the Mitsubishi Electric PUZ-HA36NKA cost to run per year?

At its rated efficiency it costs about $804-$2,452 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,033 in Phoenix and $2,081 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the Mitsubishi Electric PUZ-HA36NKA?

ENERGY STAR lists 11 certified combinations for this outdoor unit. The highest-rated ones use PLA-A36EA, Trane / Mitsubishi Electric TPLA0A0361EA70A, PKA-A36KA.

What refrigerant does the Mitsubishi Electric PUZ-HA36NKA use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.
