Questions5
What is the SEER2 rating of the Airquest D5CUHAH36AAK+KSAIC0701230?
The Airquest D5CUHAH36AAK+KSAIC0701230 is rated at up to 17.0 SEER2 and 10.0 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 2537 certified matchups SEER2 ranges from 15.2-17.0.
Is the Airquest D5CUHAH36AAK+KSAIC0701230 good for cold climates?
Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 31,600 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 Airquest D5CUHAH36AAK+KSAIC0701230 cost to run per year?
At its rated efficiency it costs about $985-$2,660 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,217 in Phoenix and $2,225 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 D5CUHAH36AAK+KSAIC0701230?
ENERGY STAR lists 2537 certified combinations for this outdoor unit. The highest-rated ones use FTMA5B48L0C, EA*5X48M21A, FMA5X36**AL.
What refrigerant does the Airquest D5CUHAH36AAK+KSAIC0701230 use?
It uses R-454B.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
