ACiQ / ACiQ Standard
ACiQ Standard 12k R-454B 115V Mini-Split
A one-ton Standard unit on 115V, this R-454B zone rates 23.2 SEER2, 12.5 EER2, and 10.4 HSPF2, and it is ENERGY STAR certified. Heating runs 12,000 BTU at 47F, 10,000 BTU at 17F, and 7,300 BTU at 5F. It's not cold-climate designated, so treat the 5F figure as the honest limit, but through moderate winters it performs well on a standard circuit.

Frequently asked questions
- Can I install the ACiQ Standard 12,000 BTU R-454B 115V (ACIQ-12WS-HP115C / ACIQ-12ZS-HP115C) myself, or do I need a pro?
- ACiQ Standard 12,000 BTU R-454B 115V (ACIQ-12WS-HP115C / ACIQ-12ZS-HP115C) 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 Standard 12,000 BTU R-454B 115V (ACIQ-12WS-HP115C / ACIQ-12ZS-HP115C) keep heating in a cold winter?
- The manufacturer publishes 7,300 BTU/h of heating output at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 10.4 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 Standard 12,000 BTU R-454B 115V (ACIQ-12WS-HP115C / ACIQ-12ZS-HP115C) need?
- Published electrical requirements: 115 V voltage, 18 A minimum circuit ampacity, and 20 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
- What warranty does the ACiQ Standard 12,000 BTU R-454B 115V (ACIQ-12WS-HP115C / ACIQ-12ZS-HP115C) carry?
- The manufacturer publishes these warranty tiers: Standard: 7 yr parts / 12 yr compressor (published per-line terms with online registration). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
