What is the SEER2 rating of the Sure SP17AY48AJVC?

The Sure SP17AY48AJVC is rated at up to 16.0 SEER2 and 10.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 111 certified matchups SEER2 ranges from 15.2-16.0.

Is the Sure SP17AY48AJVC good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 37,600 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the Sure SP17AY48AJVC cost to run per year?

At its rated efficiency it costs about $1,240-$3,062 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,546 in Phoenix and $2,514 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 Sure SP17AY48AJVC?

ENERGY STAR lists 111 certified combinations for this outdoor unit. The highest-rated ones use TCFY4824STANM, TCFY4821STANM.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 37,600 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 70% of central heat pumps.
You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 111 certified pairings.

Think twice if…

Cooling cost matters most - its SEER2 is below average for central heat pumps.

Questions5

What is the SEER2 rating of the Sure SP17AY48AJVC?: The Sure SP17AY48AJVC is rated at up to 16.0 SEER2 and 10.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 111 certified matchups SEER2 ranges from 15.2-16.0.
Is the Sure SP17AY48AJVC good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 37,600 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
How much does the Sure SP17AY48AJVC cost to run per year?: At its rated efficiency it costs about $1,240-$3,062 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,546 in Phoenix and $2,514 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 Sure SP17AY48AJVC?: ENERGY STAR lists 111 certified combinations for this outdoor unit. The highest-rated ones use TCFY4824STANM, TCFY4821STANM.
What refrigerant does the Sure SP17AY48AJVC use?: It uses R-454B.
