Review
The ACiQ 4-ton system bridges affordability and performance in the mid-tier HVAC market. This unit pairs a 100,000 BTU gas furnace with 48,000 BTU cooling capacity in a downflow/horizontal configuration suitable for basements or attics. ACiQ positions this model as a straight replacement for older Goodman units like the GSX130483 series, making it attractive for contractors managing legacy equipment swaps without complete system redesigns.
The 97% AFUE rating places this furnace in the high-efficiency category, recovering nearly all combustion heat instead of venting it away. Cooling delivers 13 SEER1 efficiency with a single-stage reciprocating compressor and R454B refrigerant, meaning lower operating costs than 90-92 AFUE units but moderate cooling expenses compared to two-stage 14-16 SEER systems. The variable-speed ECM blower reaching 2,000 CFM maximum allows precise airflow matching to heating and cooling demands, reducing runtime and noise.
Pros & Cons
Pros
- 97% AFUE efficiency reduces heating costs significantly compared to 95% AFUE competitors, saving roughly 2% annually on gas bills
- Modulating gas burner adjusts flame intensity for consistent comfort and lower energy waste versus single-stage burners
- Variable-speed ECM blower motor reduces fan cycling, lowering electricity consumption and noise during partial-load operation
- R454B refrigerant meets current EPA environmental standards without ozone depletion potential
- 10-year warranty with online registration provides solid long-term protection for major components
Cons
- Single-stage compressor means cooling runs at full capacity or not at all, limiting efficiency on mild days versus two-stage models
- 13 SEER1 rating is mid-range for modern systems, so cooling bills won't be as low as 14+ SEER alternatives
- 76 dB noise level is moderately loud for an outdoor unit, which may concern neighbors in close quarters
Who Should Buy
Best For
Homeowners in colder climates who prioritize heating efficiency and run furnaces 6-8 months yearly will see the best ROI from this 97% AFUE system. Contractors installing in modest-income neighborhoods appreciate the balance of quality components and reasonable pricing without premium cooling features.
Consider Alternatives If
Buyers in hot climates where cooling dominates should seek 14+ SEER systems, and those needing ultra-quiet equipment should consider units rated under 72 dB.
Installation
Downflow configuration requires ductwork below the unit, typical for basement or attic installations. Suction and liquid lines measure 1 1/8 inches and 3/8 inches respectively with 1/2-inch insulation on the suction line and 50-foot maximum line-set length. Plastic PVC exhaust flue is required. Electrical demands 115V single-phase 60 Hz with breaker sizing between 26.3 and 45 amps, manageable for most residential panels.
Warranty & Reliability
Coverage extends 10 years on compressor, heat exchanger, and coil after online registration, which is standard for mid-market systems. This protects against major failures without labor costs, though homeowners remain responsible for refrigerant, refrigerant recovery, and service calls. Registration is essential to activate the full term.
