Review
This Goodman 3-ton system represents a practical middle-ground choice in the residential HVAC market. It pairs a high-efficiency gas furnace with a solid air conditioning unit, both from a manufacturer with decades of contractor trust. The downflow configuration makes it flexible for basement or attic installation, while the 100,000 BTU heating capacity handles most three-ton cooling requirements effectively. Online Supply's positioning emphasizes value, and the available rebate makes entry-level pricing attractive for budget-conscious homeowners.
Performance specs are impressive across the board. The furnace delivers 100,000 BTU input with 96% AFUE, meaning 96 cents of every heating dollar converts to usable heat instead of escaping up the flue. The air conditioning side produces 34,800 BTU cooling with a 16 SEER2 rating and Energy Star certification. The variable-speed ECM blower motor runs at 2000 CFM maximum and adjusts automatically, reducing energy waste during partial-load operation. Two-stage heating provides efficient low-fire operation during shoulder seasons, extending equipment lifespan.
Pros & Cons
Pros
- 96% AFUE furnace efficiency exceeds most competitors, reducing heating costs substantially
- 16 SEER2 rating (listed as SEER1) provides Energy Star certification and strong cooling efficiency
- Variable-speed ECM blower motor adjusts airflow dynamically, improving comfort and reducing runtime costs
- Two-stage burner allows low-fire operation during mild weather, minimizing short cycling
- 10-year warranty with online registration covers both heating and cooling components
- Downflow/horizontal configuration adapts to various home layouts and installation scenarios
Cons
- Single-stage compressor lacks modulating capability, missing some efficiency gains available in variable-capacity units
- 73.5 dB noise level is moderately loud, which may be noticeable in quiet neighborhoods during peak operation
- Requires plastic or PVC exhaust flue, limiting installation flexibility in older homes with masonry chimneys
Who Should Buy
Best For
Homeowners in moderate climates needing both heating and cooling efficiency should strongly consider this system. It's particularly well-suited for those prioritizing lower energy bills and reliable performance without premium pricing on variable-capacity components.
Consider Alternatives If
Buyers in extreme cold climates requiring maximum heating output or those needing whisper-quiet operation should explore alternative options with modulating compressors and sound dampening.
Installation
Installation complexity is moderate. The system requires standard 115V single-phase power with a 30-amp breaker at maximum, making electrical work straightforward for most installers. Refrigerant lines use industry-standard 3/8-inch liquid and 7/8-inch suction sizes with 3/4-inch insulation, and the 50-foot suction line length accommodates typical residential layouts. Crucially, the plastic or PVC exhaust flue requirement eliminates homes with older masonry chimneys unless expensive modifications occur.
Warranty & Reliability
The 10-year warranty with online registration covers manufacturing defects on both the furnace and air conditioning components. This is solid coverage for the price point. Registration is mandatory to activate the full term, so buyers must complete this immediately after installation. Labor and refrigerant are not covered, which is standard across the industry at this price tier.
