Review
The Goodman 3-ton gas furnace and air conditioner system represents a solid midmarket choice for residential HVAC replacement projects. Manufactured by Online Supply and designed for upflow installation, this unit balances efficiency gains with contractor-friendly specs. The combination of a 96% AFUE furnace with a 16 SEER2 cooler makes sense for homeowners tired of aging equipment but unwilling to invest in premium systems. Goodman's reputation for straightforward engineering and parts availability has earned contractor trust over decades.
Performance metrics confirm this system's capable design. The furnace delivers 100,000 BTU of heating through a two-stage burner, while the 3-ton condenser produces 34,800 BTU of cooling. An ECM multi-speed blower reaches 1,600 CFM maximum and modulates heating delivery for better comfort. The 96% AFUE rating means substantially lower gas bills compared to 80-90% baseline units. At 16 SEER2, cooling efficiency sits above mid-market standards. Electrical requirements are modest, needing only 208/230V single-phase service with 18.7 to 30 amp breaker sizing.
Pros & Cons
Pros
- Exceptional 96% AFUE furnace efficiency cuts heating costs significantly compared to standard 80% systems
- 16 SEER2 cooling rating delivers solid air conditioning efficiency for energy-conscious homeowners
- Two-stage burner and ECM blower motor provide precise temperature control and quieter operation
- PVC flue compatibility simplifies installation in modern homes without masonry chimneys
- 10-year warranty with online registration offers solid protection for residential applications
Cons
- 73.5 dB noise level runs louder than premium systems, noticeable during furnace operation
- Single-stage cooling condenser lacks modulating capability of higher-end units
- Specs show conflicting tonnage information, creating potential confusion during ordering
Who Should Buy
Best For
Contractors installing systems in homes with upflow ductwork constraints and homeowners seeking reliable mid-tier efficiency without premium pricing. This system works well for moderate climates where heating demands justify the efficient furnace but extreme cooling loads aren't a primary concern.
Consider Alternatives If
Buyers in extremely hot climates needing variable-capacity cooling or those seeking the quietest possible operation should explore alternatives.
Installation
Installation follows standard split-system protocols. PVC flue compatibility eliminates costly chimney modifications in homes lacking masonry vents. The unit accepts R410A or R22 refrigerant, though R22 availability requires upgrading existing systems. Upflow configuration works with right-side flue positioning. Included A-coil evaporator and 50-foot suction/liquid line set simplify field setup. Contractors should verify 208/230V availability before installation begins.
Warranty & Reliability
Goodman provides 10 years of coverage with online registration, protecting compressor, coils, and heat exchanger. This extended warranty period exceeds many competitors and reflects manufacturer confidence in component durability. Coverage requires proper installation and maintenance but doesn't impose unusual restrictions that complicate claims processing.
