Our take in 30 seconds
Best for: hot and mild climatesStrengths
- Cooling efficiency up to SEER2 24.7, better than 93% of models
- Variable-speed compressor: quieter, steadier temperatures and better humidity control
- Also sold under 2 other badges, so you can compare more quotes for the same unit
Good to know
- Only 38% of its heat output remains at 5°F; plan on backup heat in hard freezes
- Uses R-410A, a refrigerant being phased down; future service may cost more
- Efficiency depends on the indoor unit: SEER2 ranges 20–24.7, so ask which pairing you're quoted

Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Mitsubishi Electric PUZ-A24NHA8*** at the three ENERGY STAR test temperatures (cooling capacity is 24,000 BTU/h for reference).
Retention at 17°F: 54% · at 5°F: 38%. Learn how to use these numbers in our cold-climate guide.

Same equipment sold under other brands
These listings share the same certifying manufacturer (Mitsubishi Electric U.S. HVAC Division) and identical certified capacities and efficiency ratings, so they are almost certainly the same hardware with a different badge. If you get quotes for any of them, you are comparing installation price and warranty, not equipment. How rebadging works.

Frequently asked questions
How much does the Mitsubishi Electric PUZ-A24NHA8*** cost to run per year?
At the U.S. average residential electricity price of 18.16¢/kWh and typical national heating and cooling hours, we estimate about $1,146 per year ($906 heating, $240 cooling). It ranges from about $590 in Louisiana to $2,787 in Alaska.
Does the Mitsubishi Electric PUZ-A24NHA8*** work in cold weather?
It is not ENERGY STAR cold-climate certified. It delivers 10,900 BTU/h at 5°F (38% of its 47°F capacity), so in very cold climates expect more reliance on backup heat.
What size is the Mitsubishi Electric PUZ-A24NHA8***?
It is rated at 24,000 BTU/h of cooling, roughly 2 tons, and 29,000 BTU/h of heating at 47°F. Proper sizing should be confirmed with a Manual J load calculation.
Is the Mitsubishi Electric PUZ-A24NHA8*** the same as the Trane / Mitsubishi Electric PUZ-A24NHA8***?
Very likely. Both are certified by Mitsubishi Electric U.S. HVAC Division with identical capacities and efficiency ratings in the ENERGY STAR database, which indicates the same equipment sold under different brands.
