// Bottom Line
This ACiQ unit is ideal for homeowners and contractors seeking cost-effective replacement cooling without premium pricing or Energy Star certification. Best suited for moderate climates where 13 SEER meets efficiency codes without oversizing the compressor.

Review

The ACiQ 3-ton horizontal cased coil condenser occupies an important middle ground in the residential cooling market. At 36,000 BTU capacity with 13 SEER efficiency, this unit replaces aging Goodman GSX130362, GSX130363, and GSX130365 models with modern R454B refrigerant compatibility. It's neither a budget commodity nor a premium inverter-driven system, positioning it for contractors and homeowners who need reliable cooling without premium pricing.

Performance specs tell a practical story. The 36,000 BTU output handles 3-ton loads capably across temperate climates. The 13 SEER rating meets most current code requirements, though it won't qualify for Energy Star rebates. The reciprocating compressor operates at single-stage, cycling fully on and off rather than modulating. Operating at 74 dB puts it in the moderate noise range, noticeable during daytime operation but not extreme for residential settings.

Pros & Cons

Pros

  • Delivers 36,000 BTU cooling capacity at 13 SEER rating, meeting most regional efficiency standards
  • Uses R454B refrigerant, future-proofed against EPA phase-down of older refrigerants like R410A
  • Single-stage reciprocating compressor is straightforward to troubleshoot and service
  • Horizontal 17.5-inch cased coil configuration fits tight attic and utility closet installations
  • 10-year warranty with online registration provides meaningful protection for homeowner peace of mind

Cons

  • 74 dB noise level is moderate to loud, noticeable during operation for nearby neighbors
  • Not Energy Star certified, eliminating eligibility for some utility rebates and tax credits
  • Single-stage compressor cycles on/off rather than modulating, reducing efficiency during partial-load conditions

Who Should Buy

Best For

Contractors replacing failed Goodman GSX130362/363/365 units will appreciate the direct compatibility and familiar installation. Homeowners in moderate climates without aggressive rebate programs seeking straightforward, affordable cooling replacement will find good value here.

Consider Alternatives If

Skip this unit if you need Energy Star certification for rebates, require whisper-quiet operation below 70 dB, or live in high-efficiency-mandate regions requiring 14+ SEER ratings.

Installation

Installation demands standard HVAC practices. Electrical requirements specify 208/230V single-phase 60 Hz with 19.1 to 30-amp breaker sizing. Refrigerant lines use 3/8-inch liquid and 7/8-inch suction connections with sweat valve fittings and 3/8-inch insulation thickness on 30 feet of pre-insulated suction line. The 17.5-inch width fits horizontal attic and closet placements. Weighing 120 pounds, handling is manageable for two technicians.

Warranty & Reliability

Coverage includes 10 years of manufacturer protection when you register online, a straightforward process most HVAC contractors complete at installation. This warranty applies to compressor, refrigerant system, and coil defects. Registration is essential, as non-registered units receive reduced coverage. For a 3-ton system in moderate climates, 10-year protection adequately covers typical compressor lifespan under normal cycling conditions.

Frequently Asked Questions

Will this unit replace my old Goodman GSX130362? +
Yes, directly. ACiQ built this unit to replace GSX130362, GSX130363, and GSX130365 models. Mounting footprints and connection sizes match. Verify your tonnage before ordering, as tonnage variants exist. Consult your Goodman documentation or a contractor if unsure.
What's the difference between R454B and R410A refrigerant? +
R454B is EPA-approved for future compliance as R410A phases out. Performance is comparable, though R454B operates at slightly higher pressures. Existing R410A systems won't be retrofitted; R454B is mandatory for new equipment. Your old system will continue running on R410A.
How does 13 SEER compare to newer units? +
13 SEER is solid baseline efficiency, meeting most regional codes and utility requirements. Newer inverter-driven units reach 15-20 SEER, consuming 15-20% less electricity. For moderate climates, 13 SEER provides good ROI without premium pricing, though high-efficiency zones may demand 14+ SEER ratings.
Is the 74 dB noise level acceptable? +
74 dB is moderate, roughly equivalent to a vacuum cleaner or heavy traffic. It's noticeably louder than premium variable-speed units running at 70 dB or below. Acceptable depends on your location, neighbors, and sensitivity. Request acoustic testing data if noise concerns exist.
Do I need online registration for the warranty? +
Yes, registration is mandatory for the full 10-year warranty. Without it, coverage drops significantly. Most contractors register units at installation using the serial number and model information, completing the process in minutes.
