Questions5

What is the SEER2 rating of the Airquest D5CUHAH24AAK+KSAIC0701230?: The Airquest D5CUHAH24AAK+KSAIC0701230 is rated at up to 18.0 SEER2 and 11.0 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 4017 certified matchups SEER2 ranges from 15.2-18.0.
Is the Airquest D5CUHAH24AAK+KSAIC0701230 good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 20,600 BTU/h at 5°F with a COP of 2.06, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
How much does the Airquest D5CUHAH24AAK+KSAIC0701230 cost to run per year?: At its rated efficiency it costs about $609-$1,528 a year in electricity in large U.S. cities, depending on climate and local rates - for example $737 in Phoenix and $1,266 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 D5CUHAH24AAK+KSAIC0701230?: ENERGY STAR lists 4017 certified combinations for this outdoor unit. The highest-rated ones use EA*5X25M17A, FTMA5B36L0C, FTMA5X24L0B.
What refrigerant does the Airquest D5CUHAH24AAK+KSAIC0701230 use?: It uses R-454B.
