Review
The Goodman 3-ton upflow system represents a pragmatic choice in the mid-market HVAC segment. Combining a 60,000 BTU gas furnace with a 36,000 BTU air conditioner, this configuration handles most residential cooling and heating needs across small to mid-sized homes. The upflow A-coil design fits standard attic or basement installations, and Goodman's established track record in North American markets provides confidence in parts availability and service support.
Performance metrics show solid efficiency credentials. The furnace delivers 96% AFUE, meaning 96 cents of every heating dollar converts to usable heat, substantially better than legacy 80% AFUE systems. The AC side achieves 13 SEER1 efficiency with reciprocating compressor technology and single-stage operation. The multi-speed blower motor can deliver up to 1200 CFM, adapting to different ductwork configurations. Electrical requirements are modest at 115V single-phase with 19.1-30 amp breaker sizing, fitting standard home service panels.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs by 10-15% versus older single-stage units
- 13 SEER cooling component meets Energy Star thresholds and delivers 36,000 BTU capacity
- Multi-speed blower motor allows better air distribution and zoning flexibility
- PVC exhaust compatibility simplifies venting and reduces installation complexity
- 10-year warranty with online registration covers both heating and cooling components
Cons
- Single-stage compressor and burner lack modulation, cycling on and off rather than scaling to demand
- 74 dB noise level is moderately loud, noticeable during operation in quiet spaces
- Not Energy Star certified, missing qualification that some utility rebates require
Who Should Buy
Best For
Homeowners in moderate climates needing a straightforward furnace and AC replacement who prioritize reliability and value over premium features. Contractors installing systems in budget-conscious residential builds where 96% AFUE and 13 SEER performance meets customer expectations.
Consider Alternatives If
Anyone seeking variable-capacity systems, Energy Star certification, or whisper-quiet operation under 70 dB should explore higher-tier Goodman lines or competing brands.
Installation
Installation follows predictable patterns for upflow configurations. The unit accepts both R410A and R22 refrigerants, though R410A is standard in new systems. Suction line requires 3/8-inch foam insulation over the 7/8-inch copper tube, preventing condensation and efficiency loss. PVC flue venting simplifies exhaust routing compared to metal ducting. Sweat valve connections demand basic brazing skills or HVAC professional installation. Ductwork sizing and furnace placement merit attention to maximize the 1200 CFM capability.
Warranty & Reliability
Goodman backs this system with a 10-year parts warranty contingent on online registration. This covers compressor and heating exchanger defects, the two most expensive failure points. Labor and refrigerant charges fall outside coverage, so homeowners should budget separately for service calls. Registration within 30 days of installation activates the full term, making prompt paperwork essential.
