Review
The Goodman 4-ton gas furnace and air conditioner system represents solid midrange equipment for residential HVAC applications. Manufactured by Online Supply, this downflow A-coil unit combines 96% AFUE heating efficiency with 14 SEER cooling performance. The system targets homeowners upgrading from dated single-stage equipment seeking measurable efficiency gains without premium pricing. With proper installation, this combination delivers reliable operation across most residential heating and cooling demands.
Performance specs show 120,000 BTU heating output with single-stage burner technology and 48,000 BTU cooling capacity via scroll compressor. The multi-speed blower motor reaches 2000 CFM maximum airflow. Electrical requirements are modest at 115V single-phase 60Hz with 26.4 to 45 amp breaker sizing. Operating noise measures 74 dB, which is noticeable but acceptable. The system accepts R410A or R22 refrigerant with 3/8 inch liquid and 7/8 inch suction lines.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs significantly compared to standard 80-85% models
- 14 SEER cooling rating meets mid-range efficiency without Energy Star certification premium
- 120,000 BTU heating output handles most residential applications in single-stage operation
- Multi-speed blower motor optimizes airflow at 2000 CFM maximum for consistent comfort
- 10-year warranty with online registration provides substantial coverage for parts and labor
- Downflow A-coil configuration works well for attic or basement furnace placement
Cons
- Single-stage burner and compressor means less precise temperature control than two-stage models
- 74 dB noise level during operation is audible in nearby living spaces
- Not Energy Star certified, missing eligibility for some utility rebate programs
- 5-ton cooling capacity listed in specs but 48,000 BTU actual output creates inconsistency
Who Should Buy
Best For
Homeowners in moderate climates replacing 15-20 year old systems want straightforward efficiency improvements without complex two-stage operation. Contractors installing standardized residential systems appreciate Goodman's reliability and straightforward installation requirements.
Consider Alternatives If
Buyers seeking Energy Star certification or those in extreme climates requiring two-stage compressor modulation should evaluate alternatives.
Installation
Installation requires plastic or PVC exhaust flue with right-side location. Downflow configuration suits attic or basement placement with horizontal airflow routing. Multi-speed blower operates through standard thermostat control. Dimensions of 34.5 inches high by 24.5 inches wide by 28.75 inches deep fit standard utility closets. Contractors appreciate straightforward single-stage controls requiring minimal technical troubleshooting during startup.
