// Bottom Line
This horizontal unit works best for homeowners upgrading older GSX systems or installing in tight attic spaces where upflow isn't possible. The 96% AFUE heating and ENERGY STAR 13 SEER cooling deliver solid year-round efficiency without premium pricing.

Review

This 3-ton ACiQ horizontal furnace-coil system bridges budget-conscious buyers and efficiency requirements. Manufactured to replace GSX130362, GSX130363, and GSX130365 models, it delivers 100,000 BTU heating and 36,000 BTU cooling in a configuration designed specifically for horizontal attic installation. The unit combines Goodman's proven reliability with modern refrigerant standards and ENERGY STAR qualification, making it practical for homeowners tired of utility bills but unwilling to overspend.

Performance data shows solid real-world capability. The furnace achieves 96% AFUE efficiency, meaning 96 cents of every heating dollar reaches your home. Cooling comes in at 13 SEER1 with two-stage burner control for comfort modulation. The multi-speed ECM blower motor caps out at 1,600 CFM and runs on standard 115V single-phase power (19.1 to 30-amp breaker range). R454B refrigerant, 3/8-inch liquid lines, and 7/8-inch suction lines work within standard installation practices for residential systems.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency exceeds most standard gas furnaces by 5-10 percentage points
  • 13 SEER cooling with R454B refrigerant meets current EPA environmental standards
  • Multi-speed ECM blower motor adjusts to actual heating/cooling demand, reducing electricity waste
  • Two-stage burner provides better comfort control and quieter operation at part load
  • 100,000 BTU heating capacity handles demanding climates without oversizing

Cons

  • Single-stage compressor lacks variable cooling capacity for maximum efficiency gains
  • 74 dB noise level runs slightly louder than premium units during peak operation
  • Horizontal configuration limits placement flexibility compared to vertical options

Who Should Buy

Best For

Homeowners in single-story homes with horizontal attic space who need dependable heating and cooling without spending on top-tier variable-capacity systems. Contractors upgrading from older Goodman GSX models will appreciate the drop-in compatibility.

Consider Alternatives If

Buyers prioritizing ultra-quiet operation or those with space constraints should compare vertical upflow alternatives or higher-SEER variable-capacity units.

Installation

Horizontal mounting requires adequate attic clearance and structural support for the 120-pound unit. Standard sweat valve connections and PVC/plastic exhaust flue compatibility align with typical residential installations. The system needs 30 feet of suction line insulation (3/8-inch thickness included) to prevent efficiency loss. Most HVAC contractors complete installation in one full day when upgrading existing systems.

Warranty & Reliability

Ten-year full parts coverage applies with online registration, protecting against compressor failure, coil leaks, and component defects. This warranty matches industry-standard coverage for mid-tier equipment and covers labor in many cases depending on your service agreement. Registration takes minutes and significantly extends peace of mind.

Frequently Asked Questions

What cooling capacity does this system deliver? +
The unit provides 36,000 BTU (3 tons) of cooling at 13 SEER1 efficiency using R454B refrigerant. This capacity works for homes averaging 1,200 to 1,500 square feet in moderate climates. Hotter regions may need the 3.5-ton option for comfortable operation during peak summer demand.
Can I install this in a cramped horizontal space? +
Yes, the 21-inch height, 21.125-inch width, and 26-inch depth fit most standard horizontal attic frames. Confirm suction line routing can accommodate 30 feet of copper run with proper 3/8-inch insulation. Tight spaces may require professional routing planning.
How much does this save on heating costs compared to older furnaces? +
Moving from an 80% AFUE furnace to this 96% unit cuts heating energy use by approximately 16 percent. On a $1,200 annual heating bill, expect savings near $190 per year, often recovering the upgrade cost within 5-7 years through efficiency gains alone.
Does this compare to higher-SEER variable-capacity systems? +
This single-stage unit operates at full compressor speed constantly, while variable-capacity competitors ramp down on mild days. You'll pay $2,000-$4,000 less here but accept slightly higher cooling electricity use. Best for steady climates where sustained capacity is needed most months.
Is the 10-year warranty enough protection? +
Yes, 10 years covers the lifespan when maintained properly. Most furnaces and coils last 15-20 years, so post-warranty failures are rare. Consider extended service plans for labor coverage beyond year ten if desired.
