What is the SEER2 rating of the GE Appliances NS15H24HA5?

The GE Appliances NS15H24HA5 is rated at up to 16.9 SEER2 and 9.5 EER2 for cooling and up to 8.9 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 113 certified matchups SEER2 ranges from 15.2-16.9.

Is the GE Appliances NS15H24HA5 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,900 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the GE Appliances NS15H24HA5 cost to run per year?

At its rated efficiency it costs about $650-$1,687 a year in electricity in large U.S. cities, depending on climate and local rates - for example $794 in Phoenix and $1,404 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 GE Appliances NS15H24HA5?

ENERGY STAR lists 113 certified combinations for this outdoor unit. The highest-rated ones use NCHC30BT5****+TDR, NAM24V2TA5, NAM30V3TA5.

Questions5

What is the SEER2 rating of the GE Appliances NS15H24HA5?: The GE Appliances NS15H24HA5 is rated at up to 16.9 SEER2 and 9.5 EER2 for cooling and up to 8.9 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 113 certified matchups SEER2 ranges from 15.2-16.9.
Is the GE Appliances NS15H24HA5 good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,900 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
How much does the GE Appliances NS15H24HA5 cost to run per year?: At its rated efficiency it costs about $650-$1,687 a year in electricity in large U.S. cities, depending on climate and local rates - for example $794 in Phoenix and $1,404 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 GE Appliances NS15H24HA5?: ENERGY STAR lists 113 certified combinations for this outdoor unit. The highest-rated ones use NCHC30BT5****+TDR, NAM24V2TA5, NAM30V3TA5.
What refrigerant does the GE Appliances NS15H24HA5 use?: It uses R-454B.
