Review
The Online Supply Goodman 3-ton split system represents a rare market opportunity, combining legitimate efficiency credentials with an aggressive price tag. This upflow configuration includes a 120,000 BTU furnace paired with a 34,800 BTU cooling condenser, suitable for homes ranging from 1,500 to 2,000 square feet depending on climate and insulation. For contractors and homeowners accustomed to paying $1,200 to $1,800 for comparable equipment, the $634 pricing warrants serious consideration despite the lower brand recognition of the Online Supply channel.
Performance specs tell a compelling efficiency story. The furnace delivers 96% AFUE, meaning minimal heat loss through the flue, while the condenser achieves 16 SEER1 cooling efficiency with a scroll compressor using R410A refrigerant. The two-stage burner modulates between high and low fire, reducing energy waste during mild weather. Maximum airflow reaches 2,000 CFM through the multi-speed ECM blower, providing responsive temperature control. These numbers place the system firmly in the high-efficiency category without premium pricing.
Pros & Cons
Pros
- Exceptional price-to-efficiency ratio at $634 for a complete 3-ton split system
- 96% AFUE furnace rating means 96 cents of every heating dollar converts to usable heat
- 16 SEER1 condenser exceeds the national minimum and qualifies as Energy Star certified
- Two-stage burner on furnace allows for modulated heating, reducing short-cycling and improving comfort
- Multi-speed ECM blower motor adapts to heating and cooling demands, running quieter when full power isn't needed
- 10-year warranty with online registration covers parts on both furnace and air conditioner
Cons
- Single-stage compressor on condenser unit means it runs at full capacity or off, lacking modulation for variable load conditions
- 73.5 dB noise level is audible, particularly during compressor cycling in cooling mode
- Actual tonnage is 3.5 tons for cooling but system is marketed as 3-ton, creating slight specification confusion
- Requires 115V electrical service and 18.7 to 30 amp breaker, standard but worth verifying on older homes
Who Should Buy
Best For
Homeowners replacing a failed system who prioritize efficiency over premium features, and contractors stocking affordable, reliable equipment for client installations. This system works particularly well in moderate climates where heating demand justifies the high-efficiency furnace investment.
Consider Alternatives If
Anyone seeking variable-capacity cooling or those living in extremely hot climates where single-stage compressor cycling will drive higher cooling costs and reduce comfort stability.
Installation
Installation requires standard split-system work, standard 115V 60Hz electrical service and a 18.7 to 30 amp breaker. The upflow A-coil configuration suits basements, crawlspaces, or attic locations with right-side flue exit. Suction and liquid lines measure 7/8 inch and 3/8 inch respectively, with 50 feet of pre-insulated suction line included. Plastic PVC exhaust flue is required, typical for modern high-efficiency furnaces. Professional installation is strongly recommended.
Warranty & Reliability
Coverage runs 10 years on parts when registered online, a solid commitment covering compressor, heat exchanger, and controls. This protects your $634 investment through typical equipment lifespan failures. No labor coverage is included, so factor service call costs into your budget if major repairs occur outside warranty period.
