// Bottom Line
This Goodman system delivers solid efficiency for homeowners in moderate climates who need a dependable furnace-AC combo without premium pricing. The 97% AFUE furnace and variable-speed blower make it particularly smart for homes where heating dominates the annual load.

Review

The Goodman 2 Ton upflow system bridges the gap between entry-level and mid-tier efficiency, combining a gas furnace rated 97% AFUE with an air conditioner delivering SEER16 cooling. This combo appeals to contractors and homeowners prioritizing furnace performance in heating-dominated regions. The unit carries ENERGY STAR certification and includes a 10-year warranty with online registration, positioning it as a responsible choice for budget-conscious replacements that don't sacrifice longevity.

The furnace section produces 80,000 BTU with modulating burners that adjust output in real time, minimizing the on-off cycling that wastes fuel in conventional units. The air conditioner delivers 23,600 BTU cooling capacity using a scroll compressor running on R410A or R22 refrigerant. The variable-speed ECM blower motor runs at 1,600 CFM maximum and intelligently matches airflow to load, reducing blower electricity consumption compared to fixed-speed competition. At 34.5 inches tall and 21 inches wide, it fits standard attic and basement spaces.

Pros & Cons

Pros

  • 97% AFUE furnace with modulating burners reduces gas waste and cycling losses compared to single-stage units
  • Variable-speed ECM blower motor adjusts to actual heating demand, cutting electricity use by 30-40% versus fixed-speed alternatives
  • SEER16 air conditioner rating provides above-average cooling efficiency, especially for a 2-ton system
  • Lightweight 22 lb condenser simplifies rooftop installation and reduces structural load concerns
  • Plastic PVC exhaust flue eliminates expensive metal ductwork and permits horizontal venting flexibility

Cons

  • 3 ton condenser paired with 2 ton nameplate creates a mismatch that may appear on paperwork, though physically compatible via AHRI certificate 7424266
  • Single-stage air conditioning compressor cycles on and off rather than modulating, meaning inconsistent cooling dehumidification during shoulder seasons
  • 71.5 dB noise level ranks moderately loud for residential units and may be audible during operation in quiet neighborhoods

Who Should Buy

Best For

Homeowners in northern climates replacing older furnaces who heat 7-8 months annually will see the best ROI on the high-efficiency burner. Contractors seeking ENERGY STAR-rated combo systems for quick, code-compliant replacements will appreciate the PVC exhaust simplicity and minimal electrical requirements at 12.4 amps minimum.

Consider Alternatives If

Homeowners in hot climates needing primary air conditioning should look at units with variable-capacity compressors, and those sensitive to equipment noise should audition this unit first.

Installation

Installation requires 115V single-phase 60 Hz power with a 12.4 to 20 amp breaker, making it compatible with standard residential electrical panels. The plastic PVC exhaust flue allows horizontal or upward venting without rigid metal ductwork, reducing labor time. Refrigerant line sets use standard 3/8 inch liquid and 3/4 inch suction connections with 3/4 inch insulation thickness, compatible with most existing copper runs or new installations.

Warranty & Reliability

Goodman backs this system with 10 years of parts warranty when you register the unit online within 30 days of installation. Registration is straightforward and required to activate the full term, so document your purchase and complete it promptly. No labor coverage is included, so maintenance and repair service calls are your responsibility after year one.

Frequently Asked Questions

Why does the spec sheet say 3 ton condenser when this is a 2 ton system? +
The 23,600 BTU cooling output and AHRI certificate 7424266 confirm the unit is physically compatible and tested as a 2 ton system. The condenser tonnage listed reflects the component manufacturer's rating, not the matched system tonnage. This is common in combo packages and is not a defect.
Can I install this myself, or do I need a licensed technician? +
EPA refrigerant handling requires EPA certification, so you must hire a licensed technician for the final hookup. However, the mounting, gas connections, ductwork, and electrical rough-in can often be DIY if you're experienced. Check local codes, as many jurisdictions require licensed installation regardless.
How much will my heating bill drop compared to an 80% AFUE furnace? +
At 97% AFUE versus 80% AFUE, you recover roughly 17 percentage points of fuel efficiency. On a 100 million BTU annual heating load, that translates to saving approximately 21 million BTU per year, or about 15-20% on heating costs depending on your gas rate and climate.
Is SEER16 good compared to newer air conditioners with SEER2 ratings? +
SEER1 and SEER2 are different rating methods, so direct comparison is misleading. SEER16 under the old standard roughly equals SEER12-13 under SEER2. It's above average for a basic system but trails premium variable-capacity models rated SEER2 20 or higher.
What does the 10 year warranty actually cover? +
Parts coverage includes compressor, furnace heat exchanger, blower motor, and controls. It does not cover labor, refrigerant, routine maintenance, or damage from improper installation. Warranty is voided if the unit is not registered online within 30 days.
