Review
Goodman has built a reputation for delivering dependable HVAC equipment at contractor-friendly prices, and this 3-ton system continues that tradition. The unit combines a 60,000 BTU furnace with 35,000 BTU cooling capacity in a single downflow package designed for straightforward installation in most homes. At $2,466, it positions itself between basic efficiency models and premium variable-refrigerant systems, targeting cost-conscious homeowners who want modern performance without luxury pricing.
Performance metrics justify the efficiency focus. The furnace achieves 96% AFUE, meaning 96 cents of every heating dollar converts to home warmth, compared to roughly 80 cents in systems from 15 years ago. Cooling delivers 18 SEER2 efficiency through a scroll compressor with two-stage operation, allowing the system to ramp down capacity during mild days rather than cycling on-off constantly. The variable-speed ECM blower motor adjusts airflow from 0 to 1,200 CFM, reducing energy waste during partial-load operation while maintaining 71 dB sound levels.
Pros & Cons
Pros
- 18 SEER2 cooling efficiency with two-stage compressor reduces summer energy costs by 15-20% versus baseline units
- 96% AFUE gas furnace captures nearly all fuel energy, significantly more efficient than older 80% models
- Variable-speed ECM blower motor adapts to home demand, improving comfort and reducing runtime waste
- Two-stage burner and two-stage compressor provide modulating performance for quieter operation at 71 dB
- ENERGY STAR certified system qualifies for utility rebates that can offset $300-500 of purchase price
Cons
- Title lists 3 ton cooling capacity but specs show 5 ton unit with 35,000 BTU cooling, creating significant specification confusion
- Heating and cooling tonnage mismatch means system is oversized for cooling relative to heating, which can reduce dehumidification performance
- A-coil downflow configuration limits installation flexibility, incompatible with upflow or horizontal installations
Who Should Buy
Best For
Homeowners replacing failed systems in regions with moderate heating and cooling loads who want efficiency improvements without high-end pricing. Contractors appreciate the straightforward two-stage design and availability of complete technical documentation for faster service calls.
Consider Alternatives If
Skip this if you need a system sized exactly to Manual J calculations showing undersized cooling, or if your ductwork requires upflow/horizontal coil orientation instead of downflow.
Installation
Downflow configuration suits basements and crawlspaces where the unit sits above the main floor. Requires 115V, 1-phase, 60Hz service with 21.3 to 35-amp breaker capacity, standard in most homes. Liquid and suction lines use 3/8-inch and 7/8-inch sweat connections. PVC exhaust flue is required. Dimensions of 34.5 inches high by 17.5 inches wide by 28.75 inches deep demand adequate clearance space for service access.
Warranty & Reliability
Goodman backs this unit with a 10-year parts warranty when you register online, covering compressor, heat exchanger, and blower components. Registration is straightforward and typically takes five minutes. This provides solid mid-range protection, though it doesn't match extended coverage from some premium brands. Covers manufacturer defects but excludes installation errors and improper maintenance.
