Review
The Goodman 3 Ton system delivers practical efficiency where homeowners need it most: in furnaces and air conditioners that handle both heating and cooling seasons. This upflow A-coil configuration fits standard equipment closets and basements, making it a common choice among contractors and DIY installers. With ENERGY STAR certification, a 97% AFUE furnace, and a 16 SEER cooler, this unit occupies the sweet spot between budget models and premium equipment, offering genuine efficiency gains without luxury pricing.
Performance numbers tell a solid story here. The modulating gas burner delivers 80,000 BTU heating output while maintaining 97% efficiency, meaning nearly all fuel converts to usable heat rather than venting waste. The cooling side produces 34,800 BTU at 16 SEER, using R410A refrigerant and a scroll compressor. Variable-speed ECM blower motor reaches 1600 CFM maximum, allowing the system to match capacity to actual demand rather than cycling on and off constantly. Operating at 73.5 dB is moderate, though noticeable during peak load.
Pros & Cons
Pros
- Modulating burner stages reduce energy waste compared to single-stage burners, cutting heating costs by 10-15% in typical use
- 16 SEER rating delivers solid cooling efficiency with ENERGY STAR certification, meeting modern efficiency standards
- Variable-speed ECM blower motor optimizes airflow at 1600 CFM maximum and reduces runtime energy consumption
- 97% AFUE furnace efficiency means minimal heat loss up the flue, among the best available in mid-range units
- 10-year warranty with online registration provides genuine peace of mind on both major components
Cons
- Single-stage compressor in cooling mode means less precise temperature control than two-stage or variable-capacity alternatives
- 73.5 dB noise level is moderately loud during compressor operation, noticeable in quiet homes or bedrooms near equipment
- Upflow-only configuration limits placement options for attic installations or non-traditional layouts
Who Should Buy
Best For
Homeowners in moderate to cold climates seeking balanced heating and cooling performance at reasonable cost. Contractors installing systems in homes with existing ductwork that supports upflow configuration will appreciate the straightforward installation requirements and AHRI certification backing.
Consider Alternatives If
Budget-conscious buyers wanting absolute lowest price should compare entry-level 14 SEER units, and homes needing horizontal downflow discharge should look at alternative configurations.
Installation
Upflow installation requires standard ductwork connections with 3/8 inch liquid and 7/8 inch suction line sizing. Unit dimensions of 34.5 inches height by 21 inches width by 28.75 inches depth fit most mechanical rooms. Electrically modest at 115V single phase 60Hz with 18.7 to 30 amp breaker range. Exhaust requires plastic or PVC flue venting, adding minimal complexity to most homes.
Warranty & Reliability
Ten-year warranty coverage applies when you register online with Goodman, protecting against manufacturer defects in compressor and major components. This matches industry standard for mid-tier equipment. Coverage is straightforward without unusual exclusions, though homeowners must complete registration to activate the full term.
