ACiQ / ACiQ Standard Base
ACiQ Standard Base 9k R-454B 115V Mini-Split
Standard Base is ACiQ's R-454B value tier, and this 9,000 BTU, 115V unit steps efficiency up to 21.5 SEER2 and 12.5 EER2 with a 9 HSPF2. It earns ENERGY STAR certification, which can open the door to rebates. Heating runs 10,000 BTU at 47F, 8,000 BTU at 17F, and 6,500 BTU at 5F - fine for milder winters but tapering meaningfully in deep cold, and this particular unit is not cold-climate designated.

Strengths
- ENERGY STAR certified, so it may qualify for utility or program rebates that the Essentials tier can't.
- Strong 12.5 EER2 and 21.5 SEER2 make it an efficient cooler on a convenient 115V circuit.
Weaknesses
- Heat falls to 6,500 BTU at 5F and it lacks a cold-climate rating, so severe winters will outrun it.
- As a value house brand, its dealer and support coverage is lighter than Mitsubishi or Daikin.

Frequently asked questions
- Can I install the ACiQ Standard Base 9,000 BTU R-454B 115V (ACIQ-09W-HP115C / ACIQ-09Z-HP115C) myself, or do I need a pro?
- ACiQ Standard Base 9,000 BTU R-454B 115V (ACIQ-09W-HP115C / ACIQ-09Z-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 Base 9,000 BTU R-454B 115V (ACIQ-09W-HP115C / ACIQ-09Z-HP115C) keep heating in a cold winter?
- The AHRI/ENERGY STAR certification lists 6,500 BTU/h of heating capacity at 5F. Rated heating operation extends down to 5 F. Certified heating efficiency is 9 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 Base 9,000 BTU R-454B 115V (ACIQ-09W-HP115C / ACIQ-09Z-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 Base 9,000 BTU R-454B 115V (ACIQ-09W-HP115C / ACIQ-09Z-HP115C) carry?
- The manufacturer publishes these warranty tiers: Registered: 7 yr parts / 12 yr compressor (published per-line terms with online registration). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
