A good fit if…

  • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 27,000 BTU/h at 5°F.
  • It will heat most of the year - its HSPF2 beats 82% of mini-splits.
  • You want steady temperatures and quiet running - the compressor varies its speed.
  • You want a choice of indoor units - 26 certified pairings.

Think twice if…

  • Cooling cost matters most - its SEER2 is below average for mini-splits.
  • You want the newest refrigerant - it uses R-410A, which is being phased down.

Questions5
What is the SEER2 rating of the ACIQ ACIQ-24ZPL-HP230B?
The ACIQ ACIQ-24ZPL-HP230B is rated at up to 21.5 SEER2 and 13.0 EER2 for cooling and up to 11.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 26 certified matchups SEER2 ranges from 18.4-21.5.
Is the ACIQ ACIQ-24ZPL-HP230B good for cold climates?
Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 27,000 BTU/h at 5°F with a COP of 2.21, so it is still 2.2 times as efficient as electric resistance heat at that temperature.
How much does the ACIQ ACIQ-24ZPL-HP230B cost to run per year?
At its rated efficiency it costs about $525-$1,433 a year in electricity in large U.S. cities, depending on climate and local rates - for example $651 in Phoenix and $1,201 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 ACIQ ACIQ-24ZPL-HP230B?
ENERGY STAR lists 26 certified combinations for this outdoor unit. The highest-rated ones use DIYCOOL ACIQ-24W-HH-MC, ACIQ-24W-HH-MC, 1HVAC ACIQ-24W-HH-MC.
What refrigerant does the ACIQ ACIQ-24ZPL-HP230B use?
It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

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.
