What is the SEER2 rating of the Armstrong Air A7HP19V36P-**A?

The Armstrong Air A7HP19V36P-**A is rated at up to 20.0 SEER2 and 13.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 404 certified matchups SEER2 ranges from 15.2-20.0.

Is the Armstrong Air A7HP19V36P-**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 2-ton model.

How much does the Armstrong Air A7HP19V36P-**A cost to run per year?

At its rated efficiency it costs about $567-$1,731 a year in electricity in large U.S. cities, depending on climate and local rates - for example $729 in Phoenix and $1,469 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 Armstrong Air A7HP19V36P-**A?

ENERGY STAR lists 404 certified combinations for this outdoor unit. The highest-rated ones use 7E[C,U]24AX-**+TDR, 7E[C,U]24BX-**+TDR, 7ED42BX-**+TDR.

2-ton central heat pump · A7HP19V Series

Armstrong Air A7HP19V36P-**A

Excellent cooling efficiency and below average heating efficiency for a 2-ton central heat pump, but not rated for cold climates.

Ranks #32 of 331 2 ton central heat pumps for cooling efficiency, and costs about $703 a year to run in a mixed climate like Atlanta.

A good fit if…

You want low cooling bills - its SEER2 beats 94% of central heat pumps.
You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 404 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 Armstrong Air A7HP19V36P-**A?: The Armstrong Air A7HP19V36P-**A is rated at up to 20.0 SEER2 and 13.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 404 certified matchups SEER2 ranges from 15.2-20.0.
Is the Armstrong Air A7HP19V36P-**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 2-ton model.
How much does the Armstrong Air A7HP19V36P-**A cost to run per year?: At its rated efficiency it costs about $567-$1,731 a year in electricity in large U.S. cities, depending on climate and local rates - for example $729 in Phoenix and $1,469 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 Armstrong Air A7HP19V36P-**A?: ENERGY STAR lists 404 certified combinations for this outdoor unit. The highest-rated ones use 7E[C,U]24AX-**+TDR, 7E[C,U]24BX-**+TDR, 7ED42BX-**+TDR.
What refrigerant does the Armstrong Air A7HP19V36P-**A use?: It uses R-454B.
