Review
This Goodman combination system stacks a high-efficiency gas furnace with a mid-tier air conditioner into one integrated package designed for upflow applications. The 80,000 BTU furnace paired with 48,000 BTU cooling capacity makes this suitable for moderate-sized homes seeking simplified installation. Built around proven Goodman engineering, the system targets contractors and homeowners who value straightforward technology over complex multi-stage features.
The furnace delivers 96% AFUE efficiency using a two-stage burner that modulates between high and low fire rates for improved comfort during partial-load conditions. The air conditioner achieves 14 SEER1 with a scroll compressor and single-stage operation, qualifying for Energy Star certification. The variable-speed ECM blower motor ramps to 1,600 CFM, distributing heated or cooled air efficiently while maintaining a reasonable 74 dB noise level. Refrigerant lines measure 3/8 inch liquid and 7/8 inch suction with 3/8 inch insulation thickness for proper operation.
Pros & Cons
Pros
- 96% AFUE furnace efficiency minimizes heating energy waste and reduces monthly gas bills significantly
- 14 SEER cooling rating qualifies for Energy Star certification, cutting air conditioning costs by 10-15% versus older units
- Two-stage burner adapts to heating demand, running at part load during mild weather to improve comfort and efficiency
- Variable-speed ECM blower motor reaches 1,600 CFM maximum while operating quietly at 74 dB
- Compact A-coil design fits tight spaces, 34.5 inches tall with upflow configuration ideal for basement installations
- R454B refrigerant meets modern environmental standards with lower global warming potential than R-410A
Cons
- Single-stage compressor cannot modulate cooling capacity, running full-load even during partial-load conditions on mild days
- Plastic PVC exhaust flue requirement may need upgrades if existing metal flue pipes are present
- 5-ton cooling capacity mismatches the stated 4-ton system designation, potentially causing confusion during specification
Who Should Buy
Best For
Contractors replacing failed furnace and AC units in homes with existing upflow ductwork who want to avoid the cost of multi-stage equipment. Homeowners in moderate climates who prioritize installation simplicity and straightforward efficiency gains over premium features.
Consider Alternatives If
Anyone needing variable-capacity cooling to handle humidity or those with tight noise requirements should consider inverter-driven or dual-stage alternatives.
Installation
This upflow A-coil system fits into tight vertical spaces at 34.5 inches tall by 21 inches wide. The plastic PVC exhaust flue requirement suits modern installations but requires conversion if upgrading from older metal flue systems. Electrical needs are minimal, requiring 115V single-phase 60Hz service with a 26.4 to 45-amp breaker. Refrigerant line routing uses standard 3/8 inch and 7/8 inch connections, familiar to most HVAC installers.
Warranty & Reliability
Coverage includes a transferable lifetime warranty on the heat exchanger and 10 years of parts coverage with online registration. The heat exchanger warranty is industry-leading, protecting against expensive internal corrosion failures. Parts warranty requires registration but covers compressor, blower motor, and control components for a full decade, reducing out-of-pocket repair costs during the critical early years.
