ACiQ / ACiQ Essentials Economy
ACiQ Essentials Economy 17k R-32 208/230V Mini-Split
A 230V, 18,000 BTU unit in the budget Essentials Economy tier, running R-32 at 17 SEER2, 9.5 EER2, and 8.5 HSPF2. The heating curve falls off fairly quickly: 16,500 BTU at 47F, 10,000 BTU at 17F, and 9,500 BTU at 5F. It's a low-cost ton-and-a-half zone where mild-climate cooling is the main job.

Strengths
- Delivers a ton and a half of capacity at the lowest price point in the ACiQ range.
- R-32 refrigerant keeps it on a current low-GWP platform despite the budget positioning.
Weaknesses
- Heat drops sharply from 16,500 BTU at 47F to 10,000 BTU at 17F, so cold-weather output is limited.
- Not ENERGY STAR certified, and value-brand support trails the premium field.

Frequently asked questions
- Can I install the ACiQ Essentials Economy 17,000 BTU R-32 208/230V (ACIQ-KE18W-W-HP230B / ACIQ-KE18Z-HP230B) myself, or do I need a pro?
- ACiQ Essentials Economy 17,000 BTU R-32 208/230V (ACIQ-KE18W-W-HP230B / ACIQ-KE18Z-HP230B) 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 Essentials Economy 17,000 BTU R-32 208/230V (ACIQ-KE18W-W-HP230B / ACIQ-KE18Z-HP230B) keep heating in a cold winter?
- The manufacturer publishes 9,500 BTU/h of heating output at 5F. Rated heating operation extends down to 5 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 Essentials Economy 17,000 BTU R-32 208/230V (ACIQ-KE18W-W-HP230B / ACIQ-KE18Z-HP230B) need?
- Published electrical requirements: 230 V voltage, 12 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 Essentials Economy 17,000 BTU R-32 208/230V (ACIQ-KE18W-W-HP230B / ACIQ-KE18Z-HP230B) carry?
- The manufacturer publishes these warranty tiers: Standard: 4 yr parts / 6 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.
