Review
The Goodman 3 Ton 14 SEER 80% AFUE system occupies a practical middle ground in the residential HVAC market. At $736, this matched furnace and air conditioning unit undercuts competitors significantly while maintaining respectable efficiency ratings. Online Supply's offering targets homeowners and contractors who need reliable equipment without stretching budgets. The unit handles heating through an 80,000 BTU gas furnace and cooling via a 3-ton air conditioning section, making it versatile for mixed-climate regions.
Performance specs tell a straightforward story. The furnace delivers 36,000 BTU heating output with 80% AFUE, which is competent for gas equipment but trails high-efficiency models at 95% AFUE. On the cooling side, the 14 SEER rating with scroll compressor technology translates to reliable air conditioning without premium efficiency. The multi-speed PSC blower motor runs up to 2000 CFM, providing adequate airflow for 3-ton capacity. Single-stage operation on both heating and cooling keeps runtime longer than modulating systems, though this simplicity reduces mechanical complexity.
Pros & Cons
Pros
- 80% AFUE furnace efficiency with single-stage burner keeps heating costs reasonable for gas systems
- 14 SEER rating on cooling side with scroll compressor offers reliable air conditioning performance
- Multi-speed PSC blower motor adjusts airflow up to 2000 CFM for better comfort control
- Compact upflow/downflow configuration at 30 inches tall fits tight utility closet spaces
- 10-year warranty with online registration provides solid coverage for residential installations
- $736 price point is exceptionally competitive for a complete 3-ton matched system
Cons
- Single-stage burner and condenser mean less precise modulation compared to two-stage systems, leading to slightly higher runtime costs
- 73 dB noise level is noticeably louder than modern variable-speed equipment, which could matter in noise-sensitive applications
- R410A refrigerant specification limits future retrofitting flexibility as HVAC industry transitions away from this refrigerant
Who Should Buy
Best For
Homeowners in moderate climates needing straightforward furnace and AC replacement without premium features, and contractors stocking mid-range equipment for price-sensitive residential customers. This works well in 1500-2000 square foot homes where balanced efficiency and upfront cost matter more than cutting-edge technology.
Consider Alternatives If
Anyone in extreme climates, homes over 2500 square feet, or buyers prioritizing minimal operating costs should explore higher SEER and AFUE ratings despite the larger initial investment.
Installation
This upflow unit measures 30 inches tall by 21 inches wide and deep, fitting standard utility closets without issue. Installation requires 208/230V single-phase power with 19.1 to 30 amp breaker sizing, placing it within typical residential electrical service. Metal flue venting exits from the top, and the system uses standard 3/8-inch liquid and 7/8-inch suction lines with 3/4-inch insulation thickness. Professional installation is essential for proper refrigerant charging and ductwork integration.
Warranty & Reliability
The 10-year warranty provides solid residential coverage when you register online after installation. This protects against major component failures on both furnace and air conditioning sections. Coverage includes the evaporator coil, which commonly fails in systems without warranty protection. However, warranty duration is standard rather than exceptional, so extended service plans may add value for long-term peace of mind.
