Review
The ACiQ 1.5 ton vertical cased coil occupies a practical middle ground in the retrofit market. This A-coil configuration measures 17.5 inches wide by 26 inches tall, making it suitable for tight installations where space constraints rule out larger equipment. The unit ships as a complete system with pre-attached liquid and suction lines, ready for field connections. At 120 pounds, it's manageable for two technicians, though proper rigging prevents damage during installation.
This coil delivers 18,000 BTU cooling capacity with a 14 SEER1 efficiency rating, representing solid middle-tier performance. The single-stage rotary compressor handles the cooling load consistently but cannot adjust output based on demand, meaning it runs at full capacity or not at all. R454B refrigerant aligns with EPA regulations and future-proofing concerns. The 71 dB noise level at operation is moderate, comparable to older standard-efficiency units but noticeably louder than variable-speed competitors.
Pros & Cons
Pros
- 14 SEER1 efficiency rating balances performance with affordability for mid-range retrofit work
- Modern R454B refrigerant meets current environmental standards and future regulations
- Vertical 17.5 inch width fits narrow spaces where horizontal coils won't work
- Flexible upflow/downflow configuration handles both basement and attic installations
- 10-year warranty with online registration provides solid long-term protection
Cons
- 71 dB noise level runs slightly louder than premium variable-speed units, noticeable in quiet spaces
- Single-stage compressor cannot modulate output, reducing comfort during mild weather and efficiency potential
- Not Energy Star certified, limiting appeal for eco-conscious buyers seeking maximum efficiency ratings
- Spec sheet lists both 1.5 ton title and 3 ton tonnage rating, creating confusion about actual capacity
Who Should Buy
Best For
Contractors replacing failed evaporator coils in existing 1.5 ton systems will appreciate the straightforward specs and proven compatibility. Budget-conscious homeowners upgrading cooling in tight spaces benefit from the flexible mounting and reasonable efficiency without paying for variable-speed features they may not need.
Consider Alternatives If
Homeowners in noise-sensitive areas or those seeking maximum efficiency should explore quieter variable-speed alternatives with SEER2 ratings above 16.
Installation
Installation requires 208/230V single-phase 60Hz power with a 12 to 30 amp breaker range, offering flexibility for various electrical setups. The coil accepts 3/8 inch liquid lines and 3/4 inch suction lines, with 50 feet of pre-insulated suction line included. Upflow and downflow configurations accommodate both furnace-above and furnace-below layouts. Field technicians should review the CAPF installation manual for proper brazing and evacuation procedures.
Warranty & Reliability
ACiQ provides 10 years of compressor and parts coverage upon online registration, standard for the mid-tier market. The evaporator coil itself carries separate Goodman warranty protection. Registration is straightforward and recommended within 30 days of purchase. This warranty covers manufacturing defects but excludes damage from improper installation, electrical surges, or refrigerant contamination.
