Review
Goodman's 4 Ton system combines 100,000 BTU heating capacity with 48,000 BTU cooling in a single upflow unit designed for homes needing replacement furnace and air conditioner work. The 97% AFUE furnace and 14 SEER1 air conditioner position this as a solid mid-market option for contractors billing moderate-efficiency retrofits. At this price point, the system appeals to budget-conscious homeowners and property managers who want certified Energy Star performance without premium-tier costs.
The heating side operates at 97% AFUE with a modulating burner that adjusts flame output continuously, avoiding the stop-start inefficiency of single-stage burners. Cooling delivers 14 SEER1 through a scroll compressor running at single-stage capacity, adequate for temperate regions but not optimal for high-heat areas. The variable-speed ECM blower motor runs up to 2,000 CFM and automatically adjusts between heating and cooling cycles, reducing runtime and energy draw compared to fixed-speed motors in older systems.
Pros & Cons
Pros
- 97% AFUE furnace efficiency means minimal heating fuel waste, delivering 100,000 BTU output with modulating burners for precise temperature control
- 14 SEER cooling efficiency reduces summer electricity costs, especially for homes in mixed climates
- Variable-speed ECM blower motor adjusts airflow up to 2,000 CFM, improving comfort and efficiency versus single-speed alternatives
- Compact 30x21x21 inch footprint fits tight attic or basement spaces common in retrofit situations
- Energy Star certified system qualifies for rebates in many regions, lowering upfront purchase cost
Cons
- 14 SEER1 is respectable but not cutting-edge, versus 16-18 SEER units available at higher price points
- Single-stage cooling compressor means the AC runs at full capacity or off, less efficient than variable capacity models
- Requires proper R454B refrigerant service, which some older HVAC shops may not stock
Who Should Buy
Best For
Contractors and homeowners replacing matched furnace-AC pairs who prioritize reasonable efficiency gains over premium ratings. This system works well for single-family homes up to 2,000 square feet in heating-dominated or mixed climates where modulating burners and ECM blowers deliver tangible comfort improvements.
Consider Alternatives If
Buyers seeking the absolute highest cooling efficiency or those in hot climates should look at 16+ SEER units with variable-capacity compressors instead.
Installation
Installation requires standard line sets (3/8 inch liquid, 7/8 inch suction) with 3/8 inch foam insulation on suction lines. The plastic PVC exhaust flue attaches right-side, fitting most residential furnace closets and attic spaces. Electrical demands 26.4 to 45 amp breaker at 115V single-phase 60 Hz, well within typical home service panels. AHRI certificate 7424267 confirms proper sizing and component matching.
Warranty & Reliability
Goodman includes a 10-year parts warranty when registered online, covering compressor and heat exchanger defects. Registration is straightforward via the manufacturer website and protects both furnace and AC components under one combined warranty, simplifying claims for homeowners dealing with combined system failures.
