Review
Goodman's 3-ton horizontal gas furnace and air conditioner system occupies a practical niche for contractors and homeowners dealing with space constraints. This pre-packaged unit combines a scroll compressor condenser with an 80% AFUE two-stage furnace, offering both cooling and heating in a footprint suited to attic or horizontal installation. Priced at $2,142, it positions itself as a no-frills alternative to premium brands while maintaining Energy Star certification.
Cooling performance delivers 35,000 BTU at 17 SEER, which outperforms most standard split systems rated 13-15 SEER and translates to tangible monthly savings in moderate climates. The furnace produces 80,000 BTU heating output at 80% AFUE, handling propane or natural gas. Two-stage operation on both sides reduces short-cycling and noise (71 dB), while the variable-speed blower motor adjusts CFM between near-silent operation and a maximum 2,000 CFM to match actual demand rather than running constantly at full speed.
Pros & Cons
Pros
- 17 SEER cooling efficiency exceeds the national average of 13 SEER, saving 25-30% on cooling costs vs. baseline units
- Two-stage compressor and condenser run at lower capacity during mild weather, reducing wear and noise (71 dB rating)
- Variable-speed blower motor adapts to load demand, improving comfort and reducing energy consumption during partial-load operation
- 80% AFUE furnace with two-stage burners handles both natural gas and propane, offering fuel flexibility
- Horizontal configuration is rare in pre-packaged systems, solving installation challenges in tight attic or crawlspace environments
Cons
- Product listing contains conflicting specs: advertised as 3 ton but datasheet shows 3.5 ton, creating confusion on actual capacity
- 80% AFUE is solid but not exceptional, falling short of 95%+ AFUE modulating units that cost $400-600 more
- No variable-stage furnace operation, so heating runs at two discrete settings rather than continuous modulation
Who Should Buy
Best For
Contractors installing replacement systems in homes with attic or horizontal ductwork, and homeowners in zones 4-5 who prioritize cooling efficiency and want to avoid oversized equipment. This unit's horizontal design solves real installation headaches many contractors face.
Consider Alternatives If
Buyers in cold climates (zones 1-3) who need higher AFUE furnace efficiency, or those seeking modulating compressors and variable heating for minimal operating costs.
Installation
The horizontal A-coil configuration requires careful placement in attic or crawlspace environments where upflow furnaces won't fit. Connection requires 3/8-inch liquid lines and 7/8-inch suction lines with 3/4-inch insulation; pre-flared sweat connections simplify work. Electrical demand is minimal at 120V, 1-phase 60Hz with a 21.3 to 35-amp breaker. Metal exhaust flue is mandatory for safety compliance.
Warranty & Reliability
Goodman includes a standard 10-year manufacturer warranty activated by online registration. Coverage applies to compressor, condenser, furnace heat exchanger, and evaporator coil. Registration is straightforward and typically covers defects in materials and workmanship. Parts replacement is available, though labor costs fall on the homeowner or contractor after the first year in most cases.
