Review
Goodman's 3-ton upflow system represents intelligent budget positioning in the value HVAC segment. At $504, this unit pairs a 96% AFUE gas furnace with an 18 SEER1 air conditioner, delivering two-stage heating and cooling without premium pricing. The scroll compressor and variable-speed ECM blower indicate Goodman invested in operational efficiency rather than flashy features. This system targets homeowners seeking measurable energy savings and contractors needing dependable equipment for volume installations.
Real-world performance numbers tell the story. The 120,000 BTU furnace heats efficiently via two-stage burners that modulate between 40-100% capacity, while the 35,000 BTU condenser cools at 18 SEER1 efficiency. The variable-speed ECM blower reaches 2,000 CFM maximum, automatically adjusting between heating and cooling cycles. At 71 dB, noise levels remain acceptable for most installations, though not silent. Energy Star qualification unlocks rebate eligibility in most utility programs, offsetting initial purchase costs within 2-3 years.
Pros & Cons
Pros
- 96% AFUE furnace efficiency with two-stage burners reduces heating costs in cold climates
- 18 SEER1 condenser unit qualifies for Energy Star, supporting seasonal cooling rebates
- Two-stage compressor and variable-speed ECM blower adapt to load demands automatically
- Compact dimensions (30 inches high, 24.5 inches wide) fit tight installation spaces easily
- PVC exhaust compatibility eliminates expensive chimney modifications on many retrofits
Cons
- Spec sheet lists conflicting tonnage (3 ton in title but 3.5 ton in specs), creating confusion during installation planning
- 71 dB noise level runs louder than premium units during compressor cycles
- 10-year warranty requires online registration, and coverage excludes labor costs for repairs
Who Should Buy
Best For
Homeowners replacing failed 15-20 year old systems where efficiency gains translate to immediate savings, and contractors managing multi-property portfolios where standardized equipment simplifies maintenance. This system works especially well in moderate climates where the heating/cooling balance favors its mid-range specifications.
Consider Alternatives If
Anyone in extreme climates (desert heat or deep cold) requiring maximum capacity, or noise-sensitive installations near bedrooms, should explore higher SEER units despite the cost premium.
Installation
Installation requires standard HVAC equipment and skills. PVC exhaust compatibility eliminates custom chimney work on many retrofits, cutting labor time significantly. The sweat-type valve connections demand competent brazing or professional help. Electrical demand stays modest at 115V single-phase with 21.9-35 amp breaker sizing, fitting standard residential panels. Compact 30-inch height accommodates upflow placement in basements or utility closets without modification.
Warranty & Reliability
Goodman backs this unit with 10 years parts coverage upon online registration, a solid commitment at this price point. Warranty excludes labor, refrigerant, and filter replacement, meaning repair costs split between covered components and your expense. Registration takes 10 minutes online and activates coverage immediately. Compare favorably against competitors offering 5-7 year warranties on budget equipment.
