ACiQ / ACiQ Standard
ACiQ Standard 9k R-454B 115V Mini-Split
The Standard tier is where ACiQ's R-454B efficiency really climbs, and this 9,000 BTU, 115V unit is a standout: 24.5 SEER2, 15 EER2, and 10.7 HSPF2. It is both ENERGY STAR certified and AHRI cold-climate designated. Heating holds well - 10,000 BTU at 47F, 9,400 BTU at 17F, and 7,300 BTU at 5F - making it a genuinely high-performing small zone on ordinary 115V power.

Frequently asked questions
- Can I install the ACiQ Standard 9,000 BTU R-454B 115V (ACIQ-09WS-HP115C / ACIQ-09ZS-HP115C) myself, or do I need a pro?
- ACiQ Standard 9,000 BTU R-454B 115V (ACIQ-09WS-HP115C / ACIQ-09ZS-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 9,000 BTU R-454B 115V (ACIQ-09WS-HP115C / ACIQ-09ZS-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 10.7 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 115V (ACIQ-09WS-HP115C / ACIQ-09ZS-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 9,000 BTU R-454B 115V (ACIQ-09WS-HP115C / ACIQ-09ZS-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.
