Review
Goodman's combination gas furnace and air conditioner system represents the practical middle ground in residential HVAC equipment. Built by a manufacturer with decades of contractor relationships, this upflow configuration handles heating and cooling in one integrated package. The unit targets homeowners seeking reliable performance without stepping into premium efficiency territory. Online Supply offers this system competitively, supported by clear documentation and accessible parts networks that contractors trust.
Performance specs reveal a capable system with some unexplained inconsistencies. The 16 SEER2 cooling efficiency rating actually exceeds the advertised 15 SEER designation, delivering approximately 29,000 BTU cooling capacity in the stated tonnage. The furnace operates at 80% AFUE with 80,000 BTU heating output and two-stage burners that modulate for comfort. Electrical requirements total 120V, 1 phase, 60 Hz with a 17.1 to 25 amp breaker range. The R410A refrigerant and scroll compressor are industry standard, though single-stage operation means full-power cooling cycles on all days.
Pros & Cons
Pros
- 16 SEER2 rating exceeds the stated 15 SEER claim, delivering better cooling efficiency than advertised
- 80,000 BTU heating capacity with two-stage burner provides responsive comfort and modulation
- Energy Star certified system qualifies for utility rebates in many regions
- High-efficiency multi-speed blower motor with 2,000 CFM max output improves air distribution
- 10-year warranty with online registration covers major components and provides peace of mind
- Scroll compressor is proven technology known for durability in residential applications
Cons
- Spec sheet shows conflicting tonnage data, listing both 2.5 ton and 3.5 ton, which creates confusion for proper sizing
- 80% AFUE is baseline efficiency for modern gas furnaces, not exceptional, lacks condensing technology for higher efficiency
- Single-stage compressor means the air conditioner runs at full capacity rather than modulating, using more energy on mild days
Who Should Buy
Best For
Homeowners in moderate climates replacing 15-20 year old systems who want straightforward, dependable performance at reasonable cost. This setup serves well for homes around 2,000-2,500 square feet where mid-range efficiency meets budget constraints.
Consider Alternatives If
Energy-conscious buyers should consider 95% AFUE condensing furnaces and variable-capacity AC units, which cost more but deliver 15-25% better efficiency over the system's life.
Installation
Installation requires standard split-system setup with 3/8 inch liquid and 7/8 inch suction lines, each up to 50 feet. The compact 30 by 21 by 21 inch footprint suits most mechanical closets or outdoor pads. Metal flue piping handles exhaust, and the upflow/horizontal configuration adapts to various home layouts. Licensed installers should verify the conflicting tonnage ratings before sizing ductwork and matching indoor coils.
Warranty & Reliability
Ten years of parts coverage activates upon online registration, covering compressor, heat exchanger, and sealed components. This protection exceeds the industry standard 5-year limited warranty on many budget units. Registration typically takes minutes and provides valuable documentation for future service calls. Coverage excludes normal maintenance items like filters and refrigerant top-offs.
