What is the SEER2 rating of the Airquest N5H9V60*K*AAA?

The Airquest N5H9V60*K*AAA is rated at up to 17.5 SEER2 and 12.0 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 1696 certified matchups SEER2 ranges from 15.2-17.5.

Is the Airquest N5H9V60*K*AAA good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 42,000 BTU/h at 5°F with a COP of 2.16, so it is still 2.2 times as efficient as electric resistance heat at that temperature.

How much does the Airquest N5H9V60*K*AAA cost to run per year?

At its rated efficiency it costs about $1,492-$4,083 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,852 in Phoenix and $3,421 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Questions5

What is the SEER2 rating of the Airquest N5H9V60*K*AAA?: The Airquest N5H9V60*K*AAA is rated at up to 17.5 SEER2 and 12.0 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 1696 certified matchups SEER2 ranges from 15.2-17.5.
Is the Airquest N5H9V60*K*AAA good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 42,000 BTU/h at 5°F with a COP of 2.16, so it is still 2.2 times as efficient as electric resistance heat at that temperature.
How much does the Airquest N5H9V60*K*AAA cost to run per year?: At its rated efficiency it costs about $1,492-$4,083 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,852 in Phoenix and $3,421 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 Airquest N5H9V60*K*AAA?: ENERGY STAR lists 1696 certified combinations for this outdoor unit. The highest-rated ones use QFVA5D6021X, FTMA5B60L0D, EA*5X61M24A.
What refrigerant does the Airquest N5H9V60*K*AAA use?: It uses R-454B.
