Review
Goodman's 2-ton downflow system represents a practical middle ground for HVAC replacement projects. Priced competitively, it combines a high-efficiency gas furnace with solid air conditioning cooling capacity. The system targets homeowners who value heating performance while maintaining reasonable equipment costs. Available through Online Supply with full manufacturer documentation, this unit carries the AHRI certification number 7424270, confirming matched component performance.
The furnace delivers 80,000 BTU heating output at 97% AFUE, meaning 97 cents of every heating dollar converts to warmth. Cooling produces 23,600 BTU at 16 SEER, handling typical cooling loads for modest-sized homes efficiently. The modulating burner fires in stages rather than on-off cycles, reducing temperature swings. The variable-speed ECM motor ramps between 0 and 1,200 CFM, matching airflow to actual heating and cooling demand rather than running constantly at full speed.
Pros & Cons
Pros
- 97% AFUE furnace converts nearly all fuel to heat, reducing heating costs significantly
- 16 SEER rating exceeds Energy Star requirements and qualifies for many utility rebates
- Modulating burner adjusts heating output in stages for consistent comfort and efficiency
- Variable-speed ECM blower motor optimizes airflow from 0 to 1,200 CFM
- Compact 32.25-inch height fits tight spaces in downflow configurations
- PVC exhaust compatibility allows flexible venting in retrofit applications
Cons
- Single-stage cooling means AC runs at full capacity even on mild days
- 71.5 dB noise level approaches upper comfort range during furnace operation
- Older SEER1 rating (not SEER2) makes direct efficiency comparisons with newer units difficult
Who Should Buy
Best For
Contractors and homeowners in moderate climates wanting high heating efficiency without high cooling demands will find strong value here. This system makes sense for replacement installations where downflow configuration suits existing ductwork and budget matters.
Consider Alternatives If
Buyers in very hot climates or larger homes over 2,000 square feet should explore higher tonnage or dual-stage cooling options.
Installation
This downflow A-coil configuration mounts vertically with 3/8-inch liquid lines and 3/4-inch suction lines, both requiring 3/4-inch insulation. Plastic PVC exhaust venting routes through the right flue location, simplifying retrofit installations. Standard 208/230V single-phase 60Hz electrical service with 12.4 to 20-amp breaker sizing fits most residential panels. Professional installation ensures proper refrigerant charge and airflow calibration.
