Amana heat pump

ALZS5BA4810A*

Ducted split systemSingle-stage

The Amana ALZS5BA4810A* is a ducted split system heat pump outdoor unit with a rated cooling capacity of 45,500 BTU/h (about 4 tons) and a single-stage compressor running on R-32 refrigerant. ENERGY STAR lists 2 certified indoor-unit pairings for it. In cold weather it still delivers 21,000 BTU/h at 5°F — 46% of its 47°F output, below the 76% median across the 308 models we track (better than 4% of them). Its HSPF2 of 7.8 is higher than 6% of models in our database, and its best certified SEER2 of 15.2 beats 6%.

Our take in 30 seconds

Best for: mild climates or homes with backup heat

Strengths

  • Uses newer, lower-impact R-32 refrigerant
  • Also sold under 2 other badges, so you can compare more quotes for the same unit

Good to know

  • Only 46% 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

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 Amana ALZS5BA4810A* 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 $2,312 per year ($1,714 heating, $598 cooling). It ranges from about $1,302 in Louisiana to $5,308 in Maine.

Does the Amana ALZS5BA4810A* work in cold weather?

It is not ENERGY STAR cold-climate certified. It delivers 21,000 BTU/h at 5°F (46% of its 47°F capacity), so in very cold climates expect more reliance on backup heat.

What size is the Amana ALZS5BA4810A*?

It is rated at 45,500 BTU/h of cooling, roughly 4 tons, and 46,000 BTU/h of heating at 47°F. Proper sizing should be confirmed with a Manual J load calculation.

Is the Amana ALZS5BA4810A* the same as the Daikin DH5SEA4810A*?

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.
