// Bottom Line
This ACiQ unit is ideal for contractors and homeowners replacing older Goodman models (GSX130483-485 series) who want dependable cooling without premium pricing. The R454B refrigerant, straightforward single-stage design, and standard 3/8" and 7/8" line sizes make it a practical drop-in replacement for budget-conscious residential applications.

Review

The ACiQ 4-ton cased coil condenser occupies a practical middle ground in the residential AC market. This unit replaces older Goodman models and uses current R454B refrigerant, making it compliant with modern environmental standards. At the entry price point, it delivers 48,000 BTU cooling capacity with 13 SEER efficiency, standard reciprocating compressor technology, and straightforward single-stage operation that contractors understand and maintain easily.

Performance specs are straightforward and honest. The unit produces 48,000 BTU cooling with 13 SEER1 efficiency using a single-stage reciprocating compressor and R454B refrigerant. Line sizes measure 3/8" liquid and 7/8" suction with sweat valve connections, requiring standard installation practices. Operating at 76 dB, it's moderately loud but acceptable for most installations. Electrical requirements are modest at 208/230V single-phase with a 45-amp maximum breaker.

Pros & Cons

Pros

  • 13 SEER efficiency meets modern standards with 48,000 BTU cooling capacity for true 4-ton performance
  • Uses environmentally friendly R454B refrigerant, aligning with current EPA regulations
  • Compact 21-inch width fits tight mechanical spaces and standard coil closets
  • Single-stage reciprocating compressor is proven technology with extensive service support
  • 10-year warranty with online registration provides solid coverage at entry-level price point

Cons

Who Should Buy

Best For

Contractors performing equipment swaps on existing Goodman systems will appreciate the direct compatibility with GSX130483-485 condensers. Homeowners in moderate climates seeking affordable, no-nonsense air conditioning without variable-speed complexity are also good candidates.

Consider Alternatives If

Skip this unit if you need quiet operation (76 dB is higher than mid-tier models), require Energy Star certification for utility rebates, or prioritize maximum efficiency in humid climates where variable-stage cooling delivers measurable savings.

Verify your existing ductwork and electrical service support 208/230V single-phase operation before ordering.

Warranty & Reliability

Goodman provides a 10-year parts warranty with online registration, which is solid coverage for entry-level equipment. Registration is straightforward and typically completed during the first service visit.

Frequently Asked Questions

Will this condenser work with my existing Goodman evaporator coil? +
Yes, this unit directly replaces GSX130483, GSX130484, and GSX130485 models. Verify your coil tonnage matches 4 tons and confirm refrigerant compatibility. Contact Goodman support if you're unsure which exact coil you have installed.
What electrical panel upgrades are required? +
The unit needs 208/230V single-phase 60Hz service with a minimum 26.3-amp breaker and maximum 45-amp breaker. Most homes have this capacity. Have a licensed electrician verify your panel can support these requirements before installation.
How does 13 SEER compare to newer equipment? +
13 SEER1 meets federal minimums but trails newer variable-stage units at 15-18 SEER. For moderate climates, the difference equals roughly 10-15% higher cooling costs annually. Single-stage operation delivers consistent performance but less part-load efficiency than modern alternatives.
Is this a good replacement for a 10-year-old AC unit? +
Yes, it's an excellent like-for-like replacement if you're replacing an older Goodman condenser. You'll see modest efficiency gains over pre-2010 equipment, improved refrigerant compliance, and straightforward installation using existing ductwork and electrical service.
What happens if the compressor fails after year one? +
The 10-year warranty covers the compressor part, but labor costs fall on you after year one. Budget 1200-1800 dollars for professional replacement including refrigerant recovery and system evacuation.
