What is the SEER2 rating of the Century HSA1960V1-**A?

The Century HSA1960V1-**A is rated at up to 18.0 SEER2 and 11.2 EER2 for cooling and up to 8.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 82 certified matchups SEER2 ranges from 16.5-18.0.

Is the Century HSA1960V1-**A good for cold climates?

It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 4-ton model.

How much does the Century HSA1960V1-**A cost to run per year?

At its rated efficiency it costs about $1,244-$3,562 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,566 in Phoenix and $3,001 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 Century HSA1960V1-**A?

ENERGY STAR lists 82 certified combinations for this outdoor unit. The highest-rated ones use 7E[C,U]50/60CX-**+TDR, 7ED50/60CX-**+TDR, 7E[C,U]48BX-**+TDR.

A good fit if…

You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 82 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
You mainly need heat - its HSPF2 is below average for central heat pumps.

Questions5

What is the SEER2 rating of the Century HSA1960V1-**A?: The Century HSA1960V1-**A is rated at up to 18.0 SEER2 and 11.2 EER2 for cooling and up to 8.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 82 certified matchups SEER2 ranges from 16.5-18.0.
Is the Century HSA1960V1-**A good for cold climates?: It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 4-ton model.
How much does the Century HSA1960V1-**A cost to run per year?: At its rated efficiency it costs about $1,244-$3,562 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,566 in Phoenix and $3,001 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 Century HSA1960V1-**A?: ENERGY STAR lists 82 certified combinations for this outdoor unit. The highest-rated ones use 7E[C,U]50/60CX-**+TDR, 7ED50/60CX-**+TDR, 7E[C,U]48BX-**+TDR.
What refrigerant does the Century HSA1960V1-**A use?: It uses R-454B.
