// Bottom Line
This combo system excels for contractors needing a compact, efficient all-in-one solution for existing upflow installations. The 96% AFUE furnace and 14 SEER air conditioner deliver solid year-round savings without requiring major ductwork modifications.

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.

Frequently Asked Questions

Why does the spec sheet list 5 tons of cooling when this is marketed as a 4-ton system? +
The 48,000 BTU cooling capacity technically equals 4 tons, but the SKU references 5-ton equipment. This likely reflects manufacturer nomenclature differences or a data entry discrepancy. Verify AHRI Certificate 7368835 for exact capacity ratings before ordering to ensure correct sizing for your application.
Can this system be installed horizontally instead of upflow? +
Configuration lists upflow/horizontal capability, but furnace orientation significantly affects performance and drainage. Horizontal installation requires proper condensate handling and may affect heat exchanger life. Consult Goodman installation instructions specific to your space before converting from upflow to horizontal operation.
How does 14 SEER1 compare to modern high-efficiency air conditioners? +
14 SEER1 falls into the mid-efficiency range. Newer dual-stage or inverter-driven units reach 16-18 SEER2. However, this unit's reliability and straightforward operation often justify the trade-off for contractors prioritizing installation speed over peak efficiency gains.
Should I choose this system over a higher SEER option? +
Choose this for budget-conscious replacements where ductwork is good and you want proven simplicity. Select higher SEER alternatives if you prioritize long-term energy savings, higher humidity control, or quieter operation. The payback period depends on local utility rates and cooling season length.
Does online registration for the 10-year parts warranty cover all components? +
Parts warranty covers major components like the compressor and blower motor after registration. Review the full warranty document for exclusions. Registration is straightforward but required within a specified timeframe to activate the extended coverage.
