Review
This 3-ton Goodman horizontal system represents the middle ground for contractors and homeowners who need balanced heating and cooling without premium pricing. The unit combines an 80,000 BTU furnace with 35,000 BTU cooling capacity in a horizontal A-coil configuration designed for attic installations. Energy Star certification and solid component quality make it reliable for most residential applications, though it falls short of high-efficiency categories in both modes.
Performance specs tell a practical story. The furnace delivers 80% AFUE efficiency with dual-stage burners and a variable-speed blower reaching 2000 CFM, while cooling achieves 18 SEER1 via a two-stage scroll compressor and condenser. The unit runs at 71 dB, stays within standard electrical requirements (21.3 to 35 amps at 120V), and uses R410A refrigerant. Real-world heating output reaches 80,000 BTU, perfect for homes averaging 1500 to 2000 square feet in moderate climates.
Pros & Cons
Pros
- 18 SEER2 cooling efficiency with two-stage compressor and condenser reduces runtime and energy bills in summer months
- 80% AFUE furnace with two-stage burner and variable-speed blower minimizes heating waste during winter operation
- Horizontal A-coil configuration fits tight attic spaces, making it ideal for retrofit installations where vertical space is limited
- Scroll compressor technology delivers reliable, quiet operation at 71 dB with minimal vibration transfer
- 10-year warranty with online registration provides meaningful coverage at this price point, protecting against compressor failure
Cons
- 80% AFUE rating lags behind high-efficiency condensing models (95% plus) by approximately 15 percentage points, adding long-term fuel costs
- Specs list 17 SEER in title but 18 SEER1 in data, creating labeling confusion around actual seasonal efficiency
- R410A refrigerant compatibility limits future serviceability if supply chains shift or regulations change within the 10-year warranty period
Who Should Buy
Best For
Contractors installing replacement systems in homes with existing horizontal ductwork and tight attic spaces will appreciate the compact 50-foot suction line and straightforward sweat valve connections. Homeowners in mixed climates with moderate heating and cooling demands benefit from the balanced 80,000 BTU furnace and 35,000 BTU cooling capacity without overpaying for ultra-high-efficiency models.
Consider Alternatives If
Buyers in very cold climates needing serious heating efficiency or extremely hot climates demanding maximum cooling should explore 95% AFUE furnaces or 20+ SEER systems respectively.
Installation
Installation complexity is moderate for licensed technicians. The horizontal design requires metal exhaust flue ducting and fits standard attic cavities at 24.5 inches tall and 26 inches deep. Sweat valve connections demand soldering skills, and the 3/8-inch liquid line with 3/4-inch suction insulation thickness follow industry standards. Variable-speed blower integration into existing ductwork typically takes 4 to 6 hours for experienced crews.
Warranty & Reliability
Online Supply backs this unit with a straightforward 10-year parts warranty following online registration. This covers the compressor, heat exchanger, and major components against defects but excludes labor and refrigerant. At this price point, the coverage is competitive and meaningful for homeowners planning to stay in their homes long term.
