Review
The Goodman 4-ton combination gas furnace and air conditioner system sits squarely in the value tier of residential HVAC equipment. Priced at $117 with a 10-year warranty, it competes against budget brands while carrying Goodman's decades of contractor trust. This upflow A-coil configuration suits standard residential installations, and the Energy Star certification signals compliance with modern efficiency standards without premium positioning.
Performance specs tell a straightforward story. The furnace delivers 100,000 BTU heating output at 96% AFUE, meaning nearly all fuel converts to usable heat. The air conditioner produces 45,500 BTU cooling capacity with a 16 SEER2 rating, which translates to measurable summer energy savings. The multi-speed ECM blower motor adjusts airflow up to 1,600 CFM, improving temperature distribution versus fixed-speed alternatives. However, the single-stage compressor operates at one fixed speed rather than modulating capacity, reducing efficiency during partial-load conditions.
Pros & Cons
Pros
- 96% AFUE furnace efficiency meets or exceeds most regional building codes
- 16 SEER2 rating qualifies for Energy Star, lowering long-term utility costs
- Two-stage burner and multi-speed ECM blower motor optimize comfort across seasons
- Plastic PVC exhaust allows flexible ductwork routing in tight installations
- 10-year warranty with online registration provides reasonable homeowner protection
Cons
- Single-stage compressor cannot modulate cooling capacity, reducing part-load efficiency and comfort
- 73 dB noise level runs louder than variable-speed alternatives during operation
- R410A refrigerant phaseout means future service costs may increase after 2025
Who Should Buy
Best For
Budget-conscious homeowners in moderate climates seeking a reliable, efficient replacement system that balances cost and performance. This works especially well for properties with standard ductwork and no extreme seasonal temperature swings.
Consider Alternatives If
Buyers in hot climates needing variable-capacity cooling, or those prioritizing whisper-quiet operation should look at two-stage or variable-speed compressor models instead.
Installation
Installation requires standard tools and moderate technical skill. The unit accepts both R410A and R22 refrigerant, easing retrofit situations. Liquid and suction line sizes are 3/8 inch and 1 1/8 inch respectively, with 1/2 inch suction insulation provided up to 50 feet. The right-side flue outlet and PVC exhaust compatibility fit most residential layouts. Electrical demand ranges from 23.9 to 40 amps at 115V single-phase, 60 Hz, matching typical household service.
Warranty & Reliability
The 10-year parts warranty requires online registration at purchase, a common Goodman practice. Coverage includes the compressor, heat exchanger, and evaporator coil under standard residential use. This period covers most major component failures during the system's expected lifespan. Extended protection plans are available but sold separately. Read the full warranty terms before registration to confirm coverage limits and exclusions.
