Review
The ACiQ 1.5-ton vertical uncased coil represents the practical middle ground in today's HVAC market. This unit delivers baseline efficiency at accessible pricing, making it attractive to contractors managing cost-sensitive projects and homeowners unwilling to pay premium prices. The A-coil configuration suits both upflow and downflow installations, and the compact 16.5 x 20.125 inch dimensions squeeze into tight spaces where larger coils won't fit. ACiQ positions itself as an accessible alternative to big-name brands, and the pricing reflects that positioning clearly.
Specifications tell a straightforward story: 18,000 BTU cooling capacity, 13 SEER1 efficiency, and single-stage rotary compressor operation. The 74 dB noise level sits in the moderate-to-loud range, noticeably higher than variable-capacity units. The R454B refrigerant is modern and forward-compatible with emerging regulations. At 208/230V single-phase with 9.1 to 15-amp breaker range, electrical requirements are standard and undemanding. The 3/8 inch liquid line and 3/4 inch suction line with matching 3/4 inch insulation thickness follow industry norms for this capacity class.
Pros & Cons
Pros
- 13 SEER efficiency is solid baseline performance without premium costs
- R454B refrigerant is next-generation, reducing future compatibility concerns
- Compact 16.5 x 20.125 inch footprint fits tight installation spaces
- Dual tonnage range (1.5 to 2 ton) provides flexible matching options
- 10-year warranty with online registration offers solid protection
- Single-stage rotary compressor design is proven and straightforward to service
Cons
- 13 SEER rating trails newer models hitting 14-16 SEER, limiting long-term energy savings
- 74 dB noise level is notably louder than variable-speed alternatives, problematic for noise-sensitive installations
- Not Energy Star certified, reducing appeal for green-conscious buyers and some rebate programs
- Single-stage operation means full or nothing, no partial load efficiency
Who Should Buy
Best For
This coil works best for contractors handling budget renovations where homeowners need working cooling without spending premium dollars. It's also solid for builders outfitting rental properties or multi-unit residential where baseline efficiency meets code requirements without stretching budgets.
Consider Alternatives If
Skip this if you prioritize quiet operation, premium efficiency ratings above 14 SEER, or Energy Star certification for rebate qualification. Homeowners in hot climates should consider higher SEER alternatives to justify long-term operating costs.
Installation
Installation is straightforward for qualified technicians. Sweat-type valve connections require basic brazing skills, and the compact dimensions (16.125 x 16.5 x 20.125 inches) fit most closets, basements, and attic spaces. The 50-foot line set provides flexibility for moderate distance runs. Weighing 120 pounds, handling requires basic equipment, not heavy machinery. ACiQ provides comprehensive documentation including installation manuals and specification sheets.
Warranty & Reliability
The 10-year warranty covers manufacturing defects and requires online registration to activate. This is solid baseline protection, matching industry standards for mid-tier equipment. Coverage is straightforward without complex conditions, though homeowners should register promptly to avoid disputes. The Goodman evaporator coil warranty ensures component-level protection across the thermal exchange surfaces.
