Review
The ACiQ 1.5 ton vertical A-coil occupies a practical middle ground in the replacement coil market. At $0 promotional pricing, it targets cost-conscious homeowners and contractors who need dependable cooling without flagship-level features. This uncased 21-inch coil works in upflow or downflow configurations, making it compatible with many existing Goodman furnace setups. The rotary compressor design is proven and serviceable, though it represents solid performance rather than cutting-edge efficiency.
Performance specs show 18,000 BTU cooling capacity with a 14 SEER1 rating, delivering reasonable efficiency for moderate climates. The unit operates on standard 208/230V single-phase power with a 12 to 30 amp breaker range, fitting most residential panels without upgrades. R454B refrigerant future-proofs the investment as older R410A stock phases out. However, the 71 dB noise level runs slightly higher than variable-capacity competitors, and single-stage operation limits part-load efficiency when cooling demand drops.
Pros & Cons
Pros
- 14 SEER efficiency provides solid cooling performance at an accessible price point
- Lightweight at 120 lbs, making installation easier for technicians working alone or in tight spaces
- R454B refrigerant is future-proof and widely supported across modern equipment
- Flexible 208/230V single-phase wiring accommodates most residential electrical panels
- 10-year warranty with online registration provides meaningful protection for DIY and contractor installs
Cons
- Single-stage compressor means no variable capacity, limiting efficiency in mild weather
- 71 dB noise level is audible and higher than some dual-stage alternatives
- Spec sheet lists conflicting tonnage information (title says 1.5 ton, specs show 3 ton), creating confusion for buyers
Who Should Buy
Best For
Homeowners in warm climates replacing worn coils on existing Goodman systems will appreciate the straightforward compatibility and reasonable cost. Contractors building budget service packages for rental properties or flip homes also find strong value here.
Consider Alternatives If
Buyers prioritizing quiet operation or maximum efficiency in variable-load conditions should compare dual-stage alternatives, as the 71 dB output and single-stage design sacrifice some comfort for price.
Installation
Installation requires proper refrigerant line sizing with 3/8-inch liquid and 3/4-inch suction connections, both clearly marked. The coil ships with 50 feet of precharged suction line insulation, eliminating on-site insulation wrapping. At 20 inches wide and 19.125 inches tall, it fits standard furnace cabinets. Most installations take two to three hours for experienced technicians, though working with a partner simplifies handling.
Warranty & Reliability
ACiQ backs this coil with a 10-year parts warranty activated through online registration. Goodman also honors the matched evaporator coil warranty on many outdoor units. Coverage includes manufacturer defects but excludes wear from poor maintenance or non-professional service. Registration is straightforward and extends protection without additional cost, making this competitive for DIY replacements.
