// Bottom Line
This 2-ton Goodman combo system excels for homeowners replacing older split systems who want genuine efficiency gains without premium pricing. The 97% AFUE furnace and 13 SEER1 AC, paired with modulating burners and variable-speed ECM blower, deliver measurable energy savings in moderate climates.

Review

The Goodman 2-ton combo system pairs a 97% AFUE gas furnace with a 13 SEER1 air conditioner into one integrated unit designed for downflow installations. This SKU replaces the older GSX130242 and comes equipped with a variable-speed ECM blower motor, modulating furnace burner, and modern R454B refrigerant. At 120 pounds and compact dimensions of 34.5 inches tall by 17.5 inches wide, it fits tight utility closets and basement corners where space is premium. Goodman's reputation for no-frills reliability rather than cutting-edge features positions this as a solid contractor choice.

Performance specs tell the story: the furnace delivers 80,000 BTU of heating output with modulating burner control, while the AC side handles 24,000 BTU of cooling at single-stage capacity. The 13 SEER1 rating and Energy Star certification mean year-round efficiency gains over 10-12 SEER1 competitors. The ECM blower varies from quiet operation to 1200 CFM maximum, adapting to heating and cooling demand. Combined with PVC exhaust flue compatibility and standard 3/8 inch suction lines, installation follows familiar protocols contractors know well.

Pros & Cons

Pros

  • 97% AFUE furnace efficiency cuts heating waste significantly compared to 80-90% models, saving roughly 15-20% on winter bills
  • 13 SEER1 air conditioner meets Energy Star standards and uses modern R454B refrigerant, reducing environmental impact
  • Modulating burner stages automatically adjust output rather than cycling full on/off, improving comfort and reducing noise
  • Variable-speed ECM blower motor adjusts CFM from near-silent to 1200 CFM maximum, eliminating the constant roar of single-speed units
  • Downflow A-coil configuration works in most residential installations where space above the furnace is limited

Cons

  • Single-stage AC compressor cannot modulate cooling capacity, so you get either full cooling or nothing, less efficient than two-stage units in mild weather
  • 75 dBA noise level is moderately loud for outdoor operation, noticeably louder than quieter high-efficiency units rated 70 dBA or below
  • Downflow configuration limits placement options, ruling out basement installations where horizontal discharge is impractical

Who Should Buy

Best For

Contractors and homeowners upgrading 15-25 year old furnace-AC systems in northern and central climates where heating dominates energy costs. This system justifies itself quickly through reduced natural gas consumption, especially if your current furnace scores below 90% AFUE.

Consider Alternatives If

Skip this if you're in a pure cooling climate, if single-stage AC cycling bothers you, or if noise under 70 dBA is essential near bedrooms. Also avoid if you lack upflow/horizontal space, since the downflow-only configuration won't work in all homes.

Installation

This downflow A-coil requires above-furnace placement with gravity return airflow, limiting retrofit options to homes with upflow capability. Electrical needs are minimal: 115V single-phase 60 Hz power with a 10.3-15 amp breaker. Refrigerant line connections use 3/4 inch suction and 3/8 inch liquid lines with sweat valve fittings. PVC exhaust flue on the right side needs proper slope and venting per Goodman specs. Most experienced HVAC techs complete installation in 4-6 hours.

Warranty & Reliability

Goodman covers this system with a 10-year parts warranty, activated through online registration at no cost. This is industry-standard protection for mid-range equipment. Coverage includes compressor, blower motor, and furnace heat exchanger. Labor costs and routine maintenance fall outside coverage. Registration takes five minutes and is worth doing immediately to lock in the full term.

Frequently Asked Questions

How much can I expect to save on heating bills versus my old furnace? +
If replacing an 80-90% AFUE furnace with this 97% model, expect 7-17% annual heating savings depending on climate and usage. In colder regions burning 100+ therms monthly, that's roughly $150-300 yearly. Savings compound over the 15-20 year lifespan, totaling $2,250-6,000 in fuel costs avoided.
Will this fit my basement if I have limited vertical space? +
The downflow configuration requires at least 35 inches of height clearance above the unit and return air ducting below, so tight basements may not work. Measure your space against 34.5 inches furnace height plus ductwork. Horizontal installations are possible but require specific air handler design, so consult a tech before purchasing.
Is 13 SEER1 good enough for hot climates where I run AC constantly? +
13 SEER1 is solid but not premium. If cooling runs 6-8 months yearly, a 15-16 SEER1 two-stage unit might pay back in 3-5 years through utility savings. This Goodman works best in mixed climates where heating and cooling are equally important, not cooling-dominated regions.
How does the modulating furnace burner compare to single-stage heating? +
Modulating burners run at 40-100% capacity rather than cycling fully on/off, maintaining steadier room temperature and reducing the 'kick on' noise. You'll notice quieter, more even heating throughout your home, plus slightly better efficiency since less cycling means less startup loss.
What's the warranty coverage if my compressor fails after year three? +
The 10-year parts warranty covers compressor replacement cost, but you pay labor. If failure occurs at year three, Goodman replaces the compressor assembly at no charge. You cover the service call and technician time, typically $800-1,500 depending on your area and contractor rates.
