ACiQ / ACiQ Standard Base
ACiQ Standard Base 36k R-454B 208/230V Mini-Split
The largest Standard Base unit is a 36,000 BTU, 230V, R-454B three-ton zone, and its numbers are the softest in this tier at 18 SEER2, 9 EER2, and 8.5 HSPF2. Notably, it is not ENERGY STAR certified. Heating runs 36,000 BTU at 47F, 24,600 BTU at 17F, and 21,400 BTU at 5F, so raw cold-weather output stays high even as efficiency lags.

Frequently asked questions
- Can I install the ACiQ Standard Base 36,000 BTU R-454B 208/230V (ACIQ-36W-HP230C / ACIQ-36Z-HP230C) myself, or do I need a pro?
- ACiQ Standard Base 36,000 BTU R-454B 208/230V (ACIQ-36W-HP230C / ACIQ-36Z-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 Base 36,000 BTU R-454B 208/230V (ACIQ-36W-HP230C / ACIQ-36Z-HP230C) keep heating in a cold winter?
- The AHRI/ENERGY STAR certification lists 21,400 BTU/h of heating capacity at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 8.5 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 36,000 BTU R-454B 208/230V (ACIQ-36W-HP230C / ACIQ-36Z-HP230C) need?
- Published electrical requirements: 230 V voltage, 33 A minimum circuit ampacity, and 35 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 36,000 BTU R-454B 208/230V (ACIQ-36W-HP230C / ACIQ-36Z-HP230C) 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.
