Review
The Goodman 3 Ton gas furnace and air conditioner system represents the practical middle ground in residential HVAC. This downflow-configured combo unit pairs a 100,000 BTU furnace with a 36,000 BTU cooling coil, making it suitable for small to average homes. It's built on proven Goodman engineering with straightforward component selection, which contractors and homeowners appreciate for its service availability and replacement-part accessibility across North America.
The furnace delivers where it counts most, the heating side. Its 97% AFUE rating means 97 cents of every dollar spent on gas converts to usable heat, among the best available in standard-efficiency furnaces. The modulating burner adapts output in stages rather than simple on-off cycling, reducing energy waste. On cooling, the 13 SEER1 rating with R454B refrigerant is competent but not aggressive. The reciprocating compressor operates at single-stage capacity, which works well for moderate cooling demands but lacks the part-load efficiency of variable-capacity competitors.
Pros & Cons
Pros
- Exceptional 97% AFUE heating efficiency reduces gas bills significantly compared to 80-90% systems
- Modulating burner stages optimize heating output and reduce cycling, improving comfort and efficiency
- Variable-speed ECM blower motor adapts to heating and cooling demands, using less electricity than fixed-speed alternatives
- 13 SEER cooling with R454B refrigerant meets current environmental standards without compromise
- 10-year warranty with online registration provides solid protection for major components
- Energy Star certified system qualifies for utility rebates in many regions
Cons
- 13 SEER cooling is respectable but trails 16+ SEER models if maximum AC efficiency is your priority
- 74 dB noise level during cooling operation may be noticeable in quiet neighborhoods or bedrooms near outdoor unit
- Single-stage compressor is less efficient than variable-capacity units during partial-load cooling scenarios
Who Should Buy
Best For
Homeowners in climates where heating costs dominate the annual HVAC bill will see the best ROI on this system. It's ideal for those upgrading from older furnaces with 80-85% AFUE who want proven reliability without paying premium prices for oversized cooling capacity.
Consider Alternatives If
Anyone in hot, humid climates relying heavily on air conditioning should consider 15+ SEER models, and buyers wanting a modulating cooling compressor won't find it here.
Installation
This downflow configuration suits basements, crawlspaces, and utility closets where ducts can feed downward. The A-coil style integrates with standard furnace plenums. Electrically, it runs on 115V single-phase 60 Hz standard household power with a 19.1 to 30-amp breaker requirement. Suction lines need 3/8 inch insulation. PVC flue venting keeps installation costs reasonable. Total unit height is 34.5 inches, making it fit most standard spaces.
Warranty & Reliability
Goodman includes a 10-year parts warranty when you register online, which is standard but solid coverage. This protects the compressor, heat exchanger, and major components against manufacturing defects. It does not cover labor, refrigerant recharge, or routine maintenance. Registration is simple and essential, do not skip it.
