Review
Goodman has built a solid reputation for delivering reliable HVAC equipment at accessible price points, and this 3-ton upflow system reflects that positioning. The unit combines a gas furnace with a matched air conditioning condenser, designed for homes needing both heating and cooling in a single integrated package. It's configured for upflow installation with an A-coil design, making it suitable for many residential retrofit applications where space is limited.
Performance metrics show the system provides 36,000 BTU of cooling capacity at 14 SEER efficiency, which is respectable for mid-market equipment. The furnace delivers 100,000 BTU of heating output at 80% AFUE with a two-stage burner setup, allowing it to modulate heating intensity. The scroll compressor operates at 73 dB, while the multi-speed blower handles airflow up to 2000 CFM. These specifications position it as a practical choice for homeowners balancing performance needs with budget constraints.
Pros & Cons
Pros
- 14 SEER rating delivers respectable cooling efficiency at mid-market price point
- 80% AFUE furnace with two-stage burners provides reasonable heating performance and fuel economy
- 36,000 BTU cooling and 100,000 BTU heating covers 3-ton capacity needs appropriately
- Multi-speed blower motor allows customized airflow from 0 to 2000 CFM for comfort control
- 10-year warranty with online registration covers compressor and parts comprehensively
- Scroll compressor design is proven reliable with lower noise output at 73 dB
Cons
- 80% AFUE is dated by current standards, modern systems reach 95%+ efficiency and lower heating bills significantly
- Single-stage compressor means the unit runs at full capacity or off, no modulation for mild conditions
- Not Energy Star certified, missing potential utility rebates that could offset purchase cost
- 73 dB noise level is moderately loud, may be noticeable during operation in quiet residential settings
Who Should Buy
Best For
Homeowners in moderate climates seeking equipment replacement without premium pricing, or contractors building budget-friendly packages for rental properties and secondary residences. This system works well for climates where heating and cooling demands are balanced rather than extreme.
Consider Alternatives If
Buyers in high-efficiency-focused regions with significant energy rebates, those seeking quieter operation, or homeowners in extreme climates where higher SEER and AFUE ratings deliver faster payback periods.
Installation
Installation requires standard refrigerant line work with 3/8 inch liquid and 3/4 inch suction lines, both valve sizes matching those dimensions. The unit requires 120V single-phase 60Hz electrical service with a minimum 18.7 amp breaker and maximum 30 amp capacity. Dimensions of 34.5 inches high by 21 inches wide by 28.75 inches deep fit most standard closets and mechanical spaces. A metal exhaust flue is mandatory for safe furnace venting.
Warranty & Reliability
Goodman backs this system with a 10-year warranty that applies to compressor and parts when you register online. This is generous coverage that typically runs longer than budget competitors, providing meaningful protection against manufacturing defects. Online registration is straightforward and unlocks the full warranty term, making it worth completing at installation.
