Review
This Goodman gas furnace and air conditioner system bundles a high-efficiency heating unit with respectable cooling capacity into one downflow package. The 100,000 BTU furnace handles heating duties while the 3-ton (36,000 BTU) condenser manages summer cooling. Goodman positions this combo as a mid-market option for homeowners replacing failed equipment or upgrading 10-to-15-year-old systems. The downflow configuration makes it ideal for basement installations feeding horizontal or vertical ductwork.
The 97% AFUE rating on the furnace side means heating efficiency that competes with premium brands, with modulating burners that stage output for better control. Cooling efficiency at 14 SEER meets ENERGY STAR standards but uses a single-stage compressor that runs full-power or off, missing the efficiency gains of two-stage designs. The variable-speed ECM blower motor adjusts airflow from 0 to 2,000 CFM based on demand, reducing energy waste compared to fixed-speed motors. Electrical requirements are modest at 115V single-phase with a 30-amp maximum breaker.
Pros & Cons
Pros
- 97% AFUE furnace efficiency means you're recovering nearly all combustion heat, translating to real savings on winter gas bills
- 14 SEER rating qualifies for ENERGY STAR, plus rebates are available in many utility districts
- Modulating burner adjusts heating output in stages, reducing on-off cycling and improving comfort
- Variable-speed ECM blower motor runs more efficiently than fixed-speed alternatives, quietly conditioning air
- R454B refrigerant is future-proof and widely stocked by technicians
- 10-year parts warranty with online registration covers compressor and major components
Cons
- Single-stage cooling compressor cycles on-off rather than modulating, less efficient than two-stage units in mild weather
- 73 dB noise level is audible, particularly from basement locations near living spaces
- Downflow configuration limits placement options to homes where furnace can sit above ductwork
Who Should Buy
Best For
Homeowners in cold-climate regions replacing aging furnace-AC combos and prioritizing heating efficiency. This system works well for basements in northern climates where 97% AFUE payback happens within 5-7 years.
Consider Alternatives If
Buyers in mild climates wanting variable-capacity cooling should compare dual-stage units, as single-stage cooling wastes energy during shoulder seasons.
Installation
Downflow configuration requires furnace placement above ductwork with gravity-assist airflow. Plastic or PVC exhaust flue is required for safe venting. The 3/8-inch liquid line and 3/4-inch suction line (with 3/4-inch insulation thickness included) connect to outdoor condenser during commissioning. Total system height is 34.5 inches, width 21 inches, depth 28.75 inches. Weight of 120 pounds keeps installation manageable for two technicians.
Warranty & Reliability
Ten-year parts warranty with online registration covers compressor failure, heat exchanger cracks, and most internal components. Labor and refrigerant are typically excluded under standard Goodman terms. Registration is essential, as many claims are denied without proof of activation. Coverage is solid for mid-tier equipment but trails extended-warranty programs some competitors offer.
