Review
The Goodman 3-ton two-stage system represents a solid mid-to-premium offering in the residential HVAC market. This unit pairs a high-efficiency air conditioning condenser with a condensing gas furnace, making it suitable for both heating and cooling climates. The Energy Star certification validates its efficiency credentials, and the 10-year warranty with online registration provides reasonable consumer protection. Goodman's reputation for durability and parts availability gives contractors confidence in long-term service.
Performance metrics impress across the board. The 35,000 BTU cooling capacity at 18 SEER means efficient summer operation, while the 100,000 BTU furnace running at 97% AFUE minimizes winter fuel waste. The scroll compressor with two-stage operation cycles intelligently between part-load and full-load modes, reducing energy consumption during mild days. Variable-speed ECM blower technology automatically adjusts airflow from low to 2000 CFM depending on demand, improving comfort consistency while keeping decibel levels at acceptable 71 dB.
Pros & Cons
Pros
- 18 SEER rating delivers measurable energy savings compared to standard 14-15 SEER units, especially valuable in high-cooling climates
- 97% AFUE furnace efficiency is among the highest available, reducing winter heating waste and lowering gas consumption
- Two-stage compressor and modulating burner adjust output precisely to load, minimizing short cycling and improving comfort
- Variable-speed ECM blower motor with 2000 CFM maximum capability optimizes air distribution and reduces runtime noise to 71 dB
- Compact 30x21x21 inch cabinet fits standard upflow/horizontal installations without requiring major ductwork modifications
Cons
- Listed price of $89 appears to be partial or promotional pricing, actual installed cost typically $5000-8000 depending on labor and ductwork
- Specs show conflicting tonnage information (title states 3 ton, specs list 5 ton), creating confusion about actual cooling capacity
- R410A refrigerant requirement means incompatibility with older R22 systems, necessitating complete coil replacement if upgrading legacy equipment
Who Should Buy
Best For
Contractors and homeowners upgrading 10-15 year old systems who want top-tier efficiency ratings with manageable upfront costs. This system performs exceptionally well in homes with moderate to large square footage where lower operating costs over 15-20 years justify higher initial investment.
Consider Alternatives If
Budget-conscious buyers seeking entry-level equipment should look elsewhere, as should anyone with existing R22 systems or extremely tight installation spaces that cannot accommodate the 30x21x21 footprint.
Installation
Installation requires standard field connections for R410A or R22 refrigerant lines using 3/8 inch liquid and 7/8 inch suction piping with 3/4 inch suction line insulation. Electrical demand needs 115V, 1-phase, 60 Hz service with breaker sizing between 21.3 and 35 amps. The PVC flue outlet (right-side mounted) integrates with plastic ductwork, and the A-coil configuration accepts both upflow and downflow orientation for flexible installation scenarios.
Warranty & Reliability
Goodman provides 10 years of parts coverage when you register the unit online after purchase, protecting against compressor and major component failures. This warranty is solid for the price point, though homeowners should verify that HVAC contractors properly register units and maintain service records. Labor costs fall outside warranty coverage, which is standard industry practice.
