Review
The ACiQ 4-ton horizontal A-coil slots into Goodman's mid-market lineup as a straightforward, no-frills indoor component. Designed for attic and utility closet mounting, this unit targets contractors who need reliable coil replacements without premium pricing. Running R454B refrigerant keeps the system future-ready as EPA regulations tighten around older refrigerants. At 120 pounds and measuring 36.25 by 35.5 by 35.5 inches, it occupies reasonable footprint for tight mechanical spaces where space constraints rule out larger equipment.
Performance lands at a honest middle ground with 14 SEER1 efficiency and 48,000 BTU/hour cooling capacity using a scroll compressor operating in single-stage mode. The unit runs at 74 dB(A), keeping noise levels acceptable for residential settings. Electrical specs call for 208/230V single-phase power with 26.4 to 45 amp breaker sizing, matching standard residential panels. Suction line insulation at 3/8 inch thickness and 30-foot line set support typical retrofit and new-build installations without special ordering.
Pros & Cons
Pros
- 14 SEER efficiency delivers 48,000 BTU cooling with solid seasonal performance for the price point
- R454B refrigerant future-proofs against upcoming EPA regulations and avoids older R410A phase-out concerns
- Compact 36.25 inch height fits horizontal attic applications tighter than comparable A-coils
- Scroll compressor provides reliable, quiet operation at 74 dB(A) during single-stage cooling
- 10-year warranty with online registration covers manufacturing defects and gives peace of mind
Cons
- 14 SEER1 trails modern 16-18 SEER2 units, adding 10-15% to long-term energy costs
- Single-stage compressor cannot modulate capacity, cycling on and off rather than ramping down on mild days
- No Energy Star certification limits appeal to homeowners chasing efficiency rebates or tax credits
Who Should Buy
Best For
Contractors retrofitting existing Goodman systems where coil replacement is needed without upgrading the entire condensing unit. Residential customers in moderate climates who prioritize compatibility and upfront cost over peak efficiency ratings.
Consider Alternatives If
Buyers seeking SEER2 ratings above 16 or homeowners in hot climates where variable-capacity cooling delivers measurable savings should explore modern variable-stage alternatives.
Installation
Installation integrates smoothly into existing Goodman systems and standard ducted air handler applications. Technicians connect 3/8 inch liquid and 7/8 inch suction lines via included fittings, then secure the coil horizontally to the air handler. Requires 208/230V power circuit with proper breaker protection. Full installation manual and kit instructions support DIY-capable contractors, though proper refrigerant charging and evacuation remain essential. Most jobs complete within 2-4 hours for experienced techs.
Warranty & Reliability
Goodman backs this coil with 10 years parts coverage once you register the unit online, a straightforward process handled through their website. Coverage includes manufacturing defects and component failure but excludes damage from improper installation, refrigerant charge issues, or system mismatches. Registration typically takes five minutes and activates immediately. Ten years aligns with typical coil lifespan expectations in residential HVAC.
