Review
The Goodman 5-ton horizontal combo system occupies a practical middle ground in the residential HVAC market. At $2,071, it's positioned well below premium Lennox or Carrier equipment while maintaining respectable efficiency credentials. This unit combines an 80% AFUE furnace with a 14 SEER air conditioner, making it suitable for homeowners who need dependable heating and cooling without investing in the highest efficiency tiers. The horizontal configuration targets attic and tight-space installations, a real limitation that ruled out numerous alternative placements.
Performance-wise, the system delivers 80,000 BTU heating and 57,000 BTU cooling capacity for appropriate 5-ton sizing. The variable-speed blower motor adjusts to actual load conditions, reducing runtime and energy consumption during mild weather or partial cooling demand. Two-stage burners optimize efficiency across different heating loads. However, at 80% AFUE, you'll see noticeably higher heating bills compared to 95% AFUE condensing furnaces, particularly in regions with long winters. The 14 SEER cooling efficiency is adequate but trails 16+ SEER models by roughly 15-20% in summer operating costs.
Pros & Cons
Pros
- 80% AFUE furnace with two-stage burners provides efficient heating without premium pricing
- Variable-speed blower motor maximizes comfort and reduces energy waste during partial-load operation
- 5-ton capacity with 57,000 cooling BTU handles most residential applications effectively
- Horizontal configuration and 38.25-inch height fit tight attic or closet installations
- 10-year warranty with online registration covers major components and provides peace of mind
Cons
- 14 SEER rating and 80% AFUE are mid-range, not high-efficiency, limiting energy savings in cold climates
- 73 dB noise level is noticeably louder than premium models, particularly during two-stage burner operation
- Not Energy Star certified, meaning higher operating costs compared to 95% AFUE and 16 SEER alternatives
Who Should Buy
Best For
Budget-conscious homeowners in moderate climates replacing 15-20 year old systems, and contractors handling rental properties where upfront cost matters more than long-term efficiency. Also suitable for secondary homes with seasonal use where premium efficiency ROI doesn't pencil out.
Consider Alternatives If
Buyers in very cold climates like Minnesota or New England should consider 95% AFUE models, and anyone prioritizing quiet operation should evaluate units rated below 70 dB.
Installation
This horizontal unit requires 208/230V single-phase power with a minimum 32.8 amp and maximum 50 amp breaker. Metal exhaust flue is mandatory for the gas furnace component. At 30 pounds with 35.5-inch width and depth dimensions, it fits most attic or utility closet spaces where horizontal airflow orientation works. The suction line uses 7/8-inch diameter with 3/4-inch insulation, and liquid line is 3/8-inch. Standard refrigerant lines extend up to 50 feet, offering reasonable flexibility for condenser placement.
Warranty & Reliability
Goodman backs this system with a standard 10-year parts warranty when you register online after purchase. This covers the compressor, heat exchanger, and most internal components. Ten years is competitive for mid-tier equipment, though some manufacturers now offer 12-year coverage. Warranty registration is straightforward through Goodman's website and should be completed immediately upon installation to activate coverage.
