// Bottom Line
This ACiQ unit is ideal for contractors and homeowners replacing older Goodman GSX130242 systems or upgrading 2-ton installations in moderate climates. The 13 SEER rating delivers solid energy savings without premium pricing, and R454B refrigerant future-proofs your system against upcoming regulatory shifts.

Review

The ACiQ 2-ton air conditioner with vertical 21-inch uncased coil occupies a practical middle ground in the residential cooling market. Designed as a direct replacement for the Goodman GSX130242, this unit combines modern refrigerant technology with accessible pricing that appeals to both contractor fleets and DIY homeowners. The 24,000 BTU cooling capacity makes it suitable for small-to-medium residential spaces, while the A-coil configuration provides flexibility for upflow or downflow installations.

Performance-wise, the 13 SEER1 efficiency rating delivers measurable energy savings compared to older single-stage equipment, translating to roughly 10-15% lower cooling costs depending on local utility rates. The rotary compressor operates at 208/230V single-phase with a 10.3 to 15-amp breaker requirement, simplifying electrical upgrades. R454B refrigerant with low global warming potential ensures compliance with emerging EPA guidelines, making this unit a forward-looking choice for systems installed today.

Pros & Cons

Pros

  • 13 SEER efficiency provides meaningful energy savings compared to older single-stage units
  • R454B refrigerant offers lower GWP, future-proofing against EPA phase-out timelines
  • Direct GSX130242 replacement simplifies retrofits with existing ductwork and coil connections
  • Compact 20-inch footprint fits standard indoor coil spaces without modification
  • 10-year warranty with online registration provides substantial peace of mind

Cons

  • Single-stage compressor limits part-load efficiency in variable-load scenarios
  • 75 dBA noise level runs slightly louder than variable-capacity competitors
  • Not Energy Star certified, missing qualification for some rebate programs

Who Should Buy

Best For

Contractors performing Goodman system replacements and homeowners in regions with moderate cooling loads who want certified efficiency improvements without variable-speed complexity. Budget-conscious upgraders will appreciate the R454B compliance and 13 SEER performance at competitive pricing.

Consider Alternatives If

Homeowners in extreme-heat climates needing maximum efficiency should consider 14+ SEER two-stage units, and those seeking Energy Star certification should look elsewhere.

Installation

Installation remains straightforward for experienced technicians. The unit requires 3/4-inch suction and 3/8-inch liquid lines with sweat valve connections, both standard in residential HVAC work. The 17.625-inch height and 20-inch width permit installation in most existing indoor coil enclosures. Pre-insulated suction line tubing at 3/4-inch thickness reduces field insulation labor.

Warranty & Reliability

ACiQ backs this unit with a 10-year parts warranty upon online registration, a solid offering for residential cooling systems. This coverage protects against compressor failure, refrigerant leaks, and coil defects, though registration is required within a specific timeframe after purchase. Labor and travel costs remain the buyer's responsibility.

Frequently Asked Questions

Does this unit qualify for Energy Star rebates? +
No. While the 13 SEER1 rating is respectable, Energy Star certification requires higher efficiency tiers. Check your local utility or state rebate programs, as some offer incentives for 13 SEER equipment regardless of Energy Star status. Always verify current rebate eligibility with your regional programs.
Can I use this to replace my old Goodman GSX130242? +
Yes, exactly. This ACiQ unit is engineered as a direct replacement. Connection points, refrigerant line sizes, and mounting footprint align with the GSX130242, reducing installation time and ductwork modification. Verify coil compatibility with your existing indoor unit before ordering.
How does 13 SEER compare to newer units? +
13 SEER is mid-range efficiency. Two-stage and variable-capacity units achieve 14-18+ SEER, but cost 25-40% more. For moderate climates and smaller homes, 13 SEER offers strong real-world savings without premium pricing or added complexity.
What does R454B refrigerant mean for me? +
R454B is a low-GWP replacement refrigerant compliant with EPA phase-down goals. It performs similarly to R410A but future-proofs your system. New systems must use R454B or equivalent after 2025, so choosing R454B now avoids future retrofit costs.
Does the 10-year warranty cover everything? +
The warranty covers parts and refrigerant leaks upon online registration. Labor, shipping, and Freon recharges are excluded. Read the full terms during registration to understand limitations and claim procedures clearly.
