Review
Goodman's horizontal A-coil combination system pairs a high-efficiency gas furnace with an air conditioning condenser, targeting budget-conscious homeowners and contractors. At $89, this offering appears aggressively priced, though the spec sheet reveals a meaningful mismatch between its stated 3-ton tonnage and actual 35,000 BTU cooling output. The unit measures 34.5 inches tall by 21 inches wide by 28.75 inches deep, fitting tight spaces where vertical coils won't work. Online Supply markets this as an energy-efficient alternative to older systems, emphasizing rebate availability through local utility programs.
The furnace delivers impressive 100,000 BTU heating capacity at 97% AFUE, meaning 97 cents of every fuel dollar converts to usable heat. The modulating burner adjusts flame intensity based on demand, reducing on-off cycling that wastes energy. The cooling condenser uses R410A refrigerant with a scroll compressor and achieves 18 SEER2 efficiency across two stages. Variable-speed ECM blower motors in both sections ramp up or down as needed, cutting standby consumption. The 71 dB noise profile sits in the moderate range, audible from nearby outdoor seating but acceptable for residential use.
Pros & Cons
Pros
- Exceptional 97% AFUE furnace efficiency reduces heating fuel costs significantly year-round
- 18 SEER2 two-stage scroll compressor earns Energy Star certification for cooling efficiency
- Modulating gas burner adapts to heating demand, minimizing cycling losses
- Variable-speed ECM blower motor optimizes airflow and reduces parasitic energy draw
- 10-year warranty with online registration provides solid coverage for parts and labor
Cons
- 35,000 BTU cooling capacity is underpowered for most 3-ton system applications, creating confusion in product naming
- 71 dB noise level runs moderately loud for a residential condenser, noticeable during operation
- Requires 115V single-phase power with 21.3 to 35 amp breaker, limiting some installation sites
Who Should Buy
Best For
Contractors and homeowners replacing aging horizontal furnace-coil combos in smaller homes or zones where 3-ton cooling capacity isn't needed. This system works well for supplemental heating and cooling in mild climates, plus vacation properties where efficiency matters more than peak capacity.
Consider Alternatives If
Anyone needing full 3-ton (36,000 BTU) cooling capacity should look elsewhere, as this unit's 35,000 BTU output falls short and creates undersizing risk in hot climates.
Installation
This horizontal configuration requires proper ductwork clearance above the unit for return and supply connections. The 3/8 inch liquid line and 7/8 inch suction line need sweat-soldered copper connections, demanding skilled HVAC technicians. Refrigerant lines accept up to 50 feet of run length, providing design flexibility. PVC exhaust flue venting exits from the right side, requiring careful routing in tight attics. Electrical connection uses standard 115V single-phase 60Hz service with breakers between 21.3 and 35 amps.
Warranty & Reliability
Goodman includes a 10-year warranty on covered parts and components when you register online, a standard practice across major manufacturers. This extended coverage period protects against compressor failure, heat exchanger cracks, and motor burnout. Registration is straightforward and typically completed at purchase. The warranty does not cover installation labor, maintenance items, or damage from improper sizing or poor installation practices.
