What is the SEER2 rating of the American Standard 4A6V8X60A1?

The American Standard 4A6V8X60A1 is rated at up to 18.0 SEER2 and 12.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the American Standard 4A6V8X60A1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 40,000 BTU/h at 5°F with a COP of 1.84, so it is still 1.8 times as efficient as electric resistance heat at that temperature.

How much does the American Standard 4A6V8X60A1 cost to run per year?

At its rated efficiency it costs about $1,410-$3,816 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,745 in Phoenix and $3,193 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 American Standard 4A6V8X60A1?

ENERGY STAR lists 86 certified combinations for this outdoor unit. The highest-rated ones use TEM8B0C60V51+TDR, TEM8A0C48V41+TDR, TEM6A0C48H41+TDR+RP.

What refrigerant does the American Standard 4A6V8X60A1 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.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 40,000 BTU/h at 5°F.
You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 86 certified pairings.

Think twice if…

You mainly need heat - its HSPF2 is below average for central heat pumps.
You want the newest refrigerant - it uses R-410A, which is being phased down.

Questions5

What is the SEER2 rating of the American Standard 4A6V8X60A1?: The American Standard 4A6V8X60A1 is rated at up to 18.0 SEER2 and 12.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
Is the American Standard 4A6V8X60A1 good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 40,000 BTU/h at 5°F with a COP of 1.84, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
How much does the American Standard 4A6V8X60A1 cost to run per year?: At its rated efficiency it costs about $1,410-$3,816 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,745 in Phoenix and $3,193 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 American Standard 4A6V8X60A1?: ENERGY STAR lists 86 certified combinations for this outdoor unit. The highest-rated ones use TEM8B0C60V51+TDR, TEM8A0C48V41+TDR, TEM6A0C48H41+TDR+RP.
