Review
This Goodman 2-ton horizontal system represents a practical middle ground in the residential HVAC market. It combines a high-efficiency 97% AFUE furnace with a respectable 16 SEER2 air conditioner, offering the kind of equipment that contractors install regularly without special sourcing delays. Horizontal configuration makes it valuable for attic or closet installations where vertical equipment cannot fit, expanding its real-world applicability beyond typical utility closets.
Performance numbers tell a straightforward story. The furnace delivers 80,000 BTU heating output with modulating burners that adjust fire intensity rather than cycling on and off, reducing temperature swings and gas waste. Cooling capacity reaches 23,600 BTU, while the variable-speed ECM blower delivers up to 1,200 CFM, automatically matching airflow to heating and cooling demand. The 115V single-phase electrical requirement keeps installation simple, requiring only a 12.4-amp minimum circuit.
Pros & Cons
Pros
- 97% AFUE furnace with modulating burners reduces gas consumption compared to single-stage units, lowering monthly heating costs by 10-15%
- 16 SEER2 air conditioner exceeds the current minimum standard of 13 SEER2, qualifying for rebates in most states
- Variable-speed ECM blower motor automatically adjusts to deliver 1,200 CFM maximum, improving comfort and reducing short-cycling
- Horizontal/upflow configuration fits tight spaces where traditional units won't work, expanding installation options
- 10-year warranty with online registration provides meaningful peace-of-mind coverage for major components
Cons
- Single-stage compressor cannot modulate cooling capacity, so it runs at full load or off without mid-range operation
- Modest 2-ton cooling capacity means it may underperform in homes over 1,000 square feet without supplemental cooling
- Requires PVC exhaust flue, which adds installation cost and complexity compared to traditional metal venting
Who Should Buy
Best For
Contractors retrofitting older homes in cold climates where higher AFUE matters, and homeowners seeking reliable efficiency improvements without ultra-premium pricing. This unit appeals to budget-conscious buyers who want measurable energy savings without paying for dual-stage cooling they may not need.
Consider Alternatives If
Anyone needing strong cooling performance in southern climates should look at higher tonnage or variable-capacity systems, and those prioritizing absolute lowest energy consumption should consider dual-stage or inverter-driven compressors.
Installation
Installation complexity stays moderate for experienced technicians. The unit requires PVC exhaust venting rather than traditional metal flue, adding cost and careful slope management to prevent condensate backup. Suction line (3/4-inch) and liquid line (3/8-inch) connections follow standard practice. The 22-pound weight and compact footprint make handling straightforward compared to heavier upflow furnaces.
Warranty & Reliability
Goodman provides a 10-year parts warranty when you register online within 30 days of installation. This covers compressor, heat exchanger, and coil failures, though labor costs and service calls remain your responsibility. Standard coverage aligns with industry norms and offers reasonable protection for a unit in this price range.
