ACiQ / Multi-Zone Essentials
ACiQ Essentials 24k R-32 208/230V 3-Zone Mini-Split
The ACiQ Multi-Zone Essentials 3-Zone 24k adds a third head on the entry R-32 line, one 208/230V outdoor unit through the value channel. It is stocked/purchasable, a priced condenser you can buy rather than a dealer quote, with professional installation still required.
Certified numbers are SEER2 23, EER2 12.5, HSPF2 10, and it is ENERGY STAR certified and AHRI cold-climate designated. Cooling capacity is 24000 BTU.
Heating holds near full into the teens - 24000 BTU at 47F, 23600 at 17F (near full but below the 47F figure), and 21600 at 5F.

Compatible indoor units
This is an outdoor unit. You choose its indoor heads separately - up to the maximum this condenser supports - and you can mix room sizes and styles across the zones. The models below are the heads this unit is documented to pair with.
Wall-mounted air handlers
9k, 12k, 18k
Model numbers
- 9k: ACIQ-09W-E-M
- 12k: ACIQ-12W-E-M
- 18k: ACIQ-18W-E-M
Sizing note: do not just add up the rooms. Multi-zone condensers have a maximum total connected capacity, and connecting more head capacity than the unit is rated for is a common installer mistake that hurts efficiency and comfort. Match total head capacity to the condenser's rating.

Frequently asked questions
- Can I install the ACiQ Multi-Zone Essentials 3-Zone 24,000 BTU R-32 208/230V (ACIQ-24Z-E-M3) myself, or do I need a pro?
- ACiQ Multi-Zone Essentials 3-Zone 24,000 BTU R-32 208/230V (ACIQ-24Z-E-M3) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
- Will the ACiQ Multi-Zone Essentials 3-Zone 24,000 BTU R-32 208/230V (ACIQ-24Z-E-M3) keep heating in a cold winter?
- The AHRI/ENERGY STAR certification lists 21,600 BTU/h of heating capacity at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 10 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
- What electrical circuit does the ACiQ Multi-Zone Essentials 3-Zone 24,000 BTU R-32 208/230V (ACIQ-24Z-E-M3) need?
- Published electrical requirements: 230 V voltage, 20 A minimum circuit ampacity, and 30 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
- How far can the outdoor unit be from the indoor head?
- The published maximum line-set length from the outdoor unit to one indoor head is 98 ft. The combined piping limit across all heads is 197 ft. The outdoor unit's factory charge covers up to 73.8 ft of line; longer runs need added refrigerant. Measure the planned routing before ordering.
- What warranty does the ACiQ Multi-Zone Essentials 3-Zone 24,000 BTU R-32 208/230V (ACIQ-24Z-E-M3) carry?
- The manufacturer publishes these warranty tiers: Registered: 4 yr parts / 6 yr compressor (published per-line ACiQ registration terms). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
