Review
Goodman's combined furnace and AC system targets the value-conscious contractor and homeowner seeking reliable performance without premium branding. This 4-ton cooling, 5-ton configuration ships ready for upflow or downflow installation with A-coil design, making it flexible for retrofit and new builds. The unit carries Energy Star certification on both heating and cooling sides, signaling genuine efficiency investment. Online Supply handles distribution with rebate availability, though pricing and promotion timing vary seasonally.
The furnace delivers 80,000 BTU heating at 96% AFUE efficiency, translating directly to reduced gas consumption during winter operation. The AC side produces 48,000 BTU cooling with a measured 16 SEER2 rating, exceeding the advertised 14 SEER spec. Multi-speed blower motors vary fan speed across demand cycles, avoiding the energy penalty of single-speed designs running constantly. The scroll compressor operates at single stage, meaning full-capacity output without mid-cycle modulation. Maximum CFM reaches 1,600, adequate for ductwork supporting 4-ton cooling loads in typical residential applications.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means lower heating bills, especially in colder months with 80,000 BTU output
- 16 SEER2 rating exceeds the 14 SEER spec claim, delivering better than advertised cooling efficiency
- Multi-speed blower motor adapts to demand, reducing noise and energy waste across seasons
- Energy Star certified across both furnace and AC components
- Scroll compressor proven technology, generally quieter and more reliable than reciprocating designs
Cons
- 5-ton tonnage claims don't align with 48,000 BTU cooling capacity, which is actually 4-ton spec only
- Single-stage compressor runs at full capacity or off, less efficient than two-stage or variable in mild weather
- 74 dB noise level is moderate, potential concern in noise-sensitive installations
Who Should Buy
Best For
Homeowners in transitional climates (zones 4-7) who heat 6+ months yearly and need reliable AC coverage. This system rewards balanced use cases where both heating and cooling matter equally, rather than extreme climates favoring one season heavily.
Consider Alternatives If
Those in hot climates prioritizing cooling should look at higher-tonnage units or variable-capacity systems, and cold-climate builders should compare modulating furnaces for better part-load efficiency.
Installation
Installation requires 115V single-phase 60 Hz power with breaker sizing between 26.4 and 45 amps. Suction line uses 1 1/8 inch diameter with 1/2 inch insulation supplied up to 50 feet, supporting longer runs without capacity loss. Liquid line connects via 3/8 inch sweat valve. PVC or plastic exhaust flue acceptable, simplifying vent retrofits. A-coil orientation suits basement, attic, or closet mounting in standard residential layouts.
Warranty & Reliability
10-year parts and labor warranty activates upon online registration after purchase. This matches industry standard for mid-tier equipment and covers compressor, heat exchanger, and major components. Registration is mandatory, so buyers must complete paperwork promptly. Goodman's warranty reputation holds solid across contractor networks, with responsive claim processing and parts availability generally strong.
