Review
The ACiQ 4 Ton horizontal furnace and air conditioner system brings solid mid-range performance to replacement and new-install markets. This unit pairs a 120,000 BTU furnace with 48,000 BTU cooling capacity in a footprint designed for horizontal installation in attics and crawlspaces. ACiQ continues to offer value-focused alternatives to premium brands, and this model's AHRI certification number 7424268 confirms compatibility with standard R454B refrigerant piping and controls.
The furnace delivers 97% AFUE efficiency with modulating burner technology that varies flame intensity from 30 to 100 percent capacity, reducing energy waste during partial-load conditions. On the cooling side, 13 SEER1 represents competent performance, though prospective buyers should note this does not yet reflect newer SEER2 testing standards. The variable-speed ECM blower motor manages up to 2,000 CFM, allowing quieter operation at 76 dBA and adapting airflow to actual heating and cooling demand.
Pros & Cons
Pros
- 97% AFUE furnace efficiency reduces natural gas or propane consumption compared to older two-stage units
- Modulating burner adjusts heating output in real time, lowering short-cycling and improving comfort consistency
- Variable-speed ECM blower motor delivers up to 2,000 CFM with quiet operation at 76 dBA
- Horizontal configuration fits tight attics and crawlspaces where traditional vertical furnaces won't work
- R454B refrigerant is non-flammable and lower-GWP than R410A, meeting current environmental standards
- 10-year warranty with online registration covers parts and labor on major components
Cons
- 13 SEER1 rating is mid-range by current standards, SEER2 conversion likely drops it to 10-11 range
- Single-stage condenser cannot modulate cooling capacity, limiting efficiency during mild weather
- Reciprocating compressor is louder and less efficient than rotary or scroll designs in competing units
- Right-side flue location limits installation flexibility in some mechanical closets or tight vents
Who Should Buy
Best For
Contractors replacing failed Goodman GSX130483-485 units will appreciate direct compatibility and streamlined ordering. Homeowners in older homes with attic or crawlspace HVAC placement benefit from the compact horizontal design without sacrificing heating efficiency.
Consider Alternatives If
Energy-conscious buyers prioritizing SEER2 ratings or those with existing ductwork optimized for variable-stage cooling should compare scroll-compressor units with dual-stage condensers.
Installation
Horizontal installation requires adequate clearance depth of 21.125 inches and width of 26 inches, typical for attic or crawlspace placement. The right-side flue location demands plastic or PVC ductwork for exhaust routing. Electrical service requires 208/230V single-phase 60 Hz, with breaker sizing between 26.3 and 45 amps. Refrigerant lines use 3/8-inch liquid and 1 1/8-inch suction connections with 1/2-inch insulation thickness and 50-foot maximum line length.
Warranty & Reliability
ACiQ backs this system with a 10-year parts and labor warranty upon online registration, covering compressor, heat exchanger, and blower motor defects. The included Goodman evaporator coil warranty extends protection to the A-coil cooling component. This warranty level is competitive for mid-tier brands and offers meaningful financial protection during the critical first decade of operation.
