Review
Goodman has built its reputation on delivering dependable HVAC equipment at reasonable prices, and this 3-ton upflow system represents that value proposition well. The combination of a 100,000 BTU furnace paired with a 34,800 BTU cooling coil addresses both heating and cooling needs in one package. This is a workhorse system designed for contractors and homeowners who want meaningful efficiency upgrades without premium pricing. The Energy Star certification signals compliance with federal standards, though the real story is in the component-level performance specs.
The furnace leads with 97% AFUE efficiency using a modulating burner that adjusts flame intensity rather than running at full blast constantly. This translates to measurably lower gas consumption compared to standard 80-90% AFUE equipment. On the cooling side, the 16 SEER1 rating reflects decent efficiency using R410A refrigerant and a scroll compressor in single-stage configuration. The variable-speed ECM blower motor adjusts airflow up to 2,000 CFM, reducing short-cycling and allowing the system to deliver conditioning more smoothly. Real-world performance will vary by ductwork quality and thermostat programming.
Pros & Cons
Pros
- 97% AFUE furnace with modulating burner reduces fuel waste and heating costs significantly compared to standard 80-85% units
- 16 SEER1 cooling efficiency with scroll compressor delivers strong performance on 34,800 BTU capacity while staying Energy Star certified
- Variable-speed ECM blower motor adapts airflow up to 2,000 CFM for better comfort and lower runtime costs
- Compact upflow A-coil configuration fits tight spaces, with 3/4 inch suction line insulation for quieter operation
- 10-year warranty with online registration provides solid protection against manufacturing defects
Cons
- Single-stage cooling condenser limits part-load efficiency during mild weather compared to two-stage alternatives
- 73.5 dB noise level is higher than premium variable-capacity systems, which may concern sound-sensitive homeowners
- 5-ton condenser paired with furnace tonnage creates a mismatch in the listed specs that needs clarification from installer
Who Should Buy
Best For
Contractors and homeowners replacing 15-plus-year-old furnace and AC systems will see immediate ROI through lower energy bills and improved heating control. Budget-conscious buyers in moderate climates benefit most from the modulating gas furnace and reliable Goodman reliability.
Consider Alternatives If
Buyers seeking ultra-quiet operation or maximum cooling efficiency in hot climates should explore variable-capacity or two-stage compressor systems instead.
Installation
Installation requires standard residential electrical service at 115V single-phase 60 Hz, with breaker sizing between 18.7 and 30 amps depending on actual load. The upflow A-coil design works in attics or closets where upward airflow makes sense. Suction line (7/8 inch) and liquid line (3/8 inch) connections are standard, with 3/4 inch insulation on the suction side already applied. PVC or plastic exhaust flue venting is required, simplifying installation in homes without metal chimney infrastructure.
Warranty & Reliability
The 10-year parts warranty requires online registration to activate, which is straightforward but essential for buyers to complete immediately after purchase. This covers manufacturing defects on sealed components and internal mechanical failure but typically excludes wear items like capacitors. Registration should be done within 30 days of installation to avoid missing the deadline and losing coverage.
