Review
The Goodman 5-ton gas furnace and air conditioner system pairs a high-efficiency furnace with conventional cooling in a market-proven configuration. Designed for upflow installations, this unit splits heating and cooling duties cleanly, letting homeowners maximize furnace efficiency without overbuying cooling capacity. At 120,000 BTU heating and 57,000 BTU cooling, the 5-ton sizing hits the mid-market sweet spot for homes needing balanced seasonal load management.
The 97% AFUE rating on the furnace is the headline specification here, delivering substantially better efficiency than the 80-90% standard in homes built before 2010. On the cooling side, 16 SEER2 with a scroll compressor and two-stage design keeps sound levels to 74 dB, a meaningful comfort factor during summer operation. The modulating burner and variable-speed ECM blower work together to reduce short-cycling, lowering operating costs and extending component life.
Pros & Cons
Pros
- 97% AFUE heating efficiency cuts natural gas consumption substantially compared to 80-85% units, translating to real monthly savings
- Variable-speed ECM blower motor adjusts airflow dynamically, improving comfort and reducing energy waste versus single-stage alternatives
- Two-stage compressor with modulating burner provides whisper-quiet operation at 74 dB during part-load cooling and heating
- ENERGY STAR certified with 10-year warranty including online registration, covering major components for a decade
- Upflow A-coil configuration suits retrofit installations where space and ductwork orientation matter
Cons
- 16 SEER2 cooling efficiency is solid but not high-end, missing the 18-20 SEER2 range that commands premium rebates
- 120,000 BTU heating capacity requires accurate sizing, risking undersizing in very cold climates without load calculations
- Requires licensed technician installation and proper gas venting, adding cost and complexity compared to electric-only heat pumps
Who Should Buy
Best For
Homeowners in moderate climates replacing aging gas furnaces who prioritize heating efficiency and want a straightforward, proven system that qualifies for standard rebates. Contractors installing systems in homes with existing natural gas service and upflow ductwork will appreciate the compatibility and quick commissioning.
Consider Alternatives If
Buyers in extreme cold climates needing 150,000+ BTU capacity, those seeking maximum cooling efficiency above 18 SEER2, or homeowners in areas transitioning away from fossil fuels should explore heat pump alternatives.
Installation
Installation demands a licensed HVAC technician due to gas line and venting requirements. The unit requires 115V single-phase 60Hz service with breaker sizing between 36.7 and 60 amps. PVC exhaust flue venting is compatible with modern code requirements. Weight of 146 pounds is manageable for basement or attic placement, and the 34.5-inch height fits most utility closets without modification.
Warranty & Reliability
Goodman provides a standard 10-year parts warranty on this system when registered online after purchase. Coverage includes compressor, blower motor, heat exchanger, and controls, representing solid protection for the major cost drivers. Online registration is quick and mandatory to activate the full term, so documentation retention matters.
