Our take in 30 seconds
Best for: mild climates or homes with backup heatStrengths
- Also sold under 2 other badges, so you can compare more quotes for the same unit
Good to know
- Only 50% of its heat output remains at 5°F; plan on backup heat in hard freezes
- Heating efficiency (HSPF2 7.8) is in the lower third of models
- Single-stage compressor runs on/off at full power, so it is less smooth than inverter models

Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Goodman GSZH502410A* at the three ENERGY STAR test temperatures (cooling capacity is 23,200 BTU/h for reference).
Retention at 17°F: 57% · at 5°F: 50%. Learn how to use these numbers in our cold-climate guide.

Same equipment sold under other brands
These listings share the same certifying manufacturer (Daikin Comfort Technologies Manufacturing, L.P.) 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 Goodman GSZH502410A* 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 $1,154 per year ($849 heating, $305 cooling). It ranges from about $656 in Louisiana to $2,636 in Maine.
Does the Goodman GSZH502410A* work in cold weather?
It is not ENERGY STAR cold-climate certified. It delivers 11,300 BTU/h at 5°F (50% of its 47°F capacity), so in very cold climates expect more reliance on backup heat.
What size is the Goodman GSZH502410A*?
It is rated at 23,200 BTU/h of cooling, roughly 2 tons, and 22,800 BTU/h of heating at 47°F. Proper sizing should be confirmed with a Manual J load calculation.
Is the Goodman GSZH502410A* the same as the Amana ASZH502410A*?
Very likely. Both are certified by Daikin Comfort Technologies Manufacturing, L.P. with identical capacities and efficiency ratings in the ENERGY STAR database, which indicates the same equipment sold under different brands.
