Review
The ACiQ 1.5 Ton vertical uncased coil represents a practical middle ground in the residential HVAC market. Built by Goodman's value-focused subsidiary, this A-coil configuration handles 18,000 BTU cooling capacity with straightforward single-stage compression. Its compact 13-inch width and 20-inch height make it suitable for confined equipment closets or attic installations. The unit operates on standard 208/230V single-phase power, keeping electrical upgrades minimal for most homes.
Performance-wise, the 14 SEER rating aligns with current federal efficiency standards and delivers predictable operating costs for moderate climates. The R454B refrigerant reflects modern environmental requirements and ensures compatibility with new Goodman equipment. At 71 decibels, noise output sits slightly above whisper-quiet models, though acceptable for outdoor placement. The rotary compressor provides reliable cooling without the variable-capacity benefits found in higher-end units, meaning efficiency dips during part-load conditions typical in spring and fall.
Pros & Cons
Pros
- 14 SEER rating meets current federal minimums with reasonable energy efficiency
- R454B refrigerant ensures compatibility with modern equipment and EPA compliance
- Lightweight at 120 lbs, simplifying rooftop or indoor installation
- Vertical 14-inch A-coil fits tight spaces better than horizontal configurations
- 10-year warranty with online registration provides solid peace of mind
Cons
- 71 dB noise level is moderately loud, noticeable from adjacent rooms
- Single-stage compressor lacks variable capacity, reducing efficiency during light-load operation
- No Energy Star certification limits rebate eligibility in some utility programs
- Spec sheet contains tonnage inconsistency (1.5 ton title vs. 3 ton spec field)
Who Should Buy
Best For
Contractors performing system replacements in residential properties where budget constraints matter, and homeowners in moderate climates looking for straightforward efficiency without variable-speed technology. This coil pairs well with Goodman condensers in retrofit scenarios.
Consider Alternatives If
Buyers prioritizing ultra-quiet operation or maximum seasonal efficiency should explore 16+ SEER models with variable-stage compressors, even if initial cost increases.
Installation
Installation involves standard 3/8-inch liquid and 3/4-inch suction lines with factory-supplied 3/4-inch suction line insulation rated for 50 feet. The coil supports both upflow and downflow configurations, offering flexibility in equipment room layouts. Contractors need 12 to 30 amp breaker sizing depending on condenser pairing. Most residential installations complete within standard timeframes using common tools.
Warranty & Reliability
Coverage spans 10 years when registered online, protecting against manufacturing defects in cooling components and structural integrity. This registration requirement is typical among budget-oriented manufacturers but adds a minor compliance step. Goodman evaporator coil warranty specifics are detailed in manufacturer documentation, so review terms before installation.
