ACiQ / ACiQ Standard
ACiQ Standard 9k R-454B 208/230V Mini-Split
The 230V Standard 9k pushes seasonal heating efficiency to a remarkable 13 HSPF2, alongside 24.6 SEER2 and 14.7 EER2 on R-454B. It is ENERGY STAR certified and cold-climate designated.
Heating comes in at 10,000 BTU at 47F, 9,300 BTU at 17F, and 8,200 BTU at 5F, so it holds most of its capacity well into the cold. This is one of the most efficient small zones ACiQ offers.

Frequently asked questions
- Can I install the ACiQ Standard 9,000 BTU R-454B 208/230V (ACIQ-09WS-HP230C / ACIQ-09ZS-HP230C) myself, or do I need a pro?
- ACiQ Standard 9,000 BTU R-454B 208/230V (ACIQ-09WS-HP230C / ACIQ-09ZS-HP230C) 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 9,000 BTU R-454B 208/230V (ACIQ-09WS-HP230C / ACIQ-09ZS-HP230C) keep heating in a cold winter?
- The manufacturer publishes 8,200 BTU/h of heating output at 5F. Rated heating operation extends down to -4 F. Certified heating efficiency is 13 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 9,000 BTU R-454B 208/230V (ACIQ-09WS-HP230C / ACIQ-09ZS-HP230C) need?
- Published electrical requirements: 230 V voltage, 12 A minimum circuit ampacity, and 15 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 9,000 BTU R-454B 208/230V (ACIQ-09WS-HP230C / ACIQ-09ZS-HP230C) 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.
