Review
Goodman's 3.5 ton system pairs a 96% AFUE furnace with a 14 SEER condenser in a proven upflow configuration. This combination addresses two critical HVAC functions with equipment that balances performance and affordability. The 80,000 BTU furnace and 42,000 BTU condenser are sized for mid-sized homes, while the A-coil design supports efficient heat transfer without excessive cost or complexity.
Heating efficiency reaches 96% AFUE through a two-stage burner and 30-foot suction line insulation that minimizes losses. The 14 SEER condenser uses a scroll compressor and operates at 73 dBA, quieter than many competing units. Variable-speed ECM blower reaches 1600 CFM and adjusts automatically, avoiding the energy waste of fixed-speed fans that run at full power regardless of demand.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means lower heating bills and minimal fuel waste compared to 80-90% units
- 14 SEER cooling efficiency qualifies for ENERGY STAR, reducing summer cooling costs by 15-20% versus baseline AC
- Two-stage burner and variable-speed ECM blower adjust output to match load, improving comfort and efficiency
- Lifetime heat exchanger warranty covers the most expensive failure point, backed by 10-year parts coverage
- Scroll compressor in the condenser is quieter at 73 dBA and more durable than rotary designs
Cons
- Single-stage condenser cannot modulate cooling capacity, limiting part-load efficiency on mild days
- 73 dBA noise level is audible from 20 feet away, may concern noise-sensitive installations
- R410A refrigerant requires certified handling and recovery, increasing service costs versus older R22 systems
Who Should Buy
Best For
Homeowners and contractors replacing complete HVAC systems in houses where upflow furnace placement works naturally, such as basements or attics. This combo excels in mixed climates where both heating and cooling run regularly throughout the year.
Consider Alternatives If
Buyers needing variable-capacity cooling for maximum efficiency on mild-weather days should consider a two-stage or modulating condenser. Noise-sensitive installations or tight mechanical spaces under 34.5 inches tall are poor fits.
Installation
Upflow configuration suits basements and crawlspaces with limited headroom. The 34.5-inch height fits most installations, though 21-inch width and 28.75-inch depth require proper clearance for service access. Two-stage burner requires standard 115V, 1-phase power and 22-35 amp breaker. Plastic PVC exhaust flue venting is standard and cost-effective compared to metal ductwork.
Warranty & Reliability
Lifetime heat exchanger coverage protects against the costliest failure point, while 10-year parts warranty applies with online registration. Heat exchanger coverage is transferable to second owners, adding resale value. Parts warranty excludes labor, so service calls still incur technician fees, but major component replacement cost is capped.
