Review
Goodman's 4-ton gas furnace and air conditioner combo represents the practical middle ground in residential HVAC. Priced competitively, this system combines a 100,000 BTU two-stage furnace with a 48,000 BTU cooling condenser in a compact upflow A-coil configuration. It's the equipment choice when budget constraints matter but complete system failure isn't an option.
Performance sits squarely in the mid-market tier. The 80% AFUE heating efficiency means roughly 80 cents of every fuel dollar converts to usable heat, standard for non-condensing furnaces. Cooling reaches 13 SEER, translating to moderate seasonal efficiency with the reciprocating compressor cycling on and off in single-stage operation. The high-efficiency multi-speed blower motor reaches 2000 CFM maximum, adjusting airflow intelligently across your ductwork.
Pros & Cons
Pros
- Two-stage burner provides better heating modulation than single-stage competitors, reducing temperature swings
- 13 SEER rating meets mid-market expectations at accessible price point
- High-efficiency multi-speed blower motor adjusts CFM up to 2000 based on load demands
- Two-piece A-coil design fits tight upflow installations more easily than alternatives
- 10-year warranty with online registration provides solid coverage for parts replacement
Cons
- 80% AFUE trails high-efficiency models by 10-15 points, meaning higher winter heating bills in cold climates
- Single-stage compressor cycles on and off rather than modulating, reducing part-load efficiency
- 76 dB noise level runs louder than premium units, noticeable in quiet neighborhoods
- No ENERGY STAR certification limits eligibility for rebates in some utility programs
Who Should Buy
Best For
Budget-conscious homeowners in moderate climates replacing 15+ year old systems will appreciate the value proposition. Rental property owners and those planning to sell within 10 years benefit from lower upfront costs without sacrificing basic reliability.
Consider Alternatives If
High-efficiency seekers in cold climates should explore 95% AFUE furnaces and 16+ SEER units, which recover their 20-30% cost premium through energy savings within 5-7 years.
Installation
Installation demands standard HVAC skill sets. The system requires 120V single-phase 60 Hz power with a 26.3 to 45 amp breaker, typical residential electrical service. Liquid and suction lines measure 3/8-inch and 1 1/8-inch respectively with 1/2-inch insulation included. Metal flue exhaust venting is mandatory. Most contractors complete installation in one workday.
Warranty & Reliability
The 10-year parts warranty activates through online registration, a reasonable protection span covering compressor, coil, and cabinet components. This covers manufacturing defects but excludes wear items and maintenance-related failures. Labor warranty details vary by installer, so confirm coverage during installation scheduling.
