2 Ton 15 SEER 80% AFUE 60,000 BTU Goodman Gas Furnace and Air Conditioner System - Horizontal Review 2026

// Bottom Line

This Goodman system works best for homeowners in moderate climates seeking reliable heating and cooling without premium pricing. The 80% AFUE furnace and 16 SEER2 condenser deliver solid year-round performance for 2-3 ton applications, making it ideal for retrofit installations and new construction where energy efficiency matters more than cutting-edge performance.

Review

The Goodman 2 Ton 15 SEER 80% AFUE horizontal furnace and air conditioner system sits solidly in the mainstream HVAC market. This unit combines a gas furnace delivering 60,000 BTU of heating with an air conditioner producing 23,600 BTU of cooling capacity. The system earns Energy Star certification and addresses homeowners seeking dependable performance without premium pricing. SKU LS38343850 replaces the older GSX16S241 model, offering incremental improvements in efficiency and technology adoption.

Performance specs reveal a balanced approach to residential comfort. The furnace achieves 80% Annual Fuel Utilization Efficiency with a two-stage burner that adjusts output based on heating demand. Cooling efficiency registers at 16 SEER2, delivering strong seasonal performance for moderate climates. The scroll compressor operates at 71.5 dBA, providing reasonable noise levels during operation. A high-efficiency multi-speed blower motor reaches 1200 CFM maximum airflow while using less electricity than single-speed alternatives, resulting in lower overall utility bills.

Pros & Cons

Pros

16 SEER2 cooling efficiency exceeds baseline standards and qualifies for Energy Star certification
Two-stage burner on furnace allows modulating heat output, reducing short-cycling and improving comfort
High-efficiency multi-speed blower motor matches airflow to demand, lowering electricity consumption
Scroll compressor design runs quieter at 71.5 dBA and demonstrates proven reliability in residential applications
10-year warranty with online registration covers parts and compressor against manufacturing defects

Cons

80% AFUE is mid-range efficiency, not high-efficiency like 95% AFUE models that reduce gas waste
Single-stage cooling compressor cannot modulate capacity, cycling on and off rather than ramping output
Metal exhaust flue requirement adds installation complexity and cost compared to direct-vent alternatives

Who Should Buy

Best For

Homeowners replacing an aging system who want measurable efficiency gains without extreme upfront costs. Contractors installing systems in mixed-climate regions where heating and cooling demands are balanced throughout the year.

Consider Alternatives If

Anyone prioritizing lowest possible heating costs should evaluate 95% AFUE models, and buyers in high-SEER requirement states may need 18+ SEER2 units.

Installation

Installation requires a metal exhaust flue, which adds cost and complexity compared to systems offering direct vent or plastic flue options. The unit accepts both R410A and R22 refrigerants, allowing technicians flexibility with existing line sets. Electrical requirements are modest at 120V single-phase 60Hz with a 12.4 to 20 amp breaker range, fitting standard residential panels. Horizontal configuration and A-coil design work well in attics and tight spaces.

Warranty & Reliability

Goodman provides a 10-year parts and compressor warranty when registered online after purchase. This coverage is competitive for mid-tier equipment but trails premium brands offering 12-year terms. Registration is straightforward and essential, protecting your investment against manufacturing failures. Labor costs for warranty service claims vary by contractor and region.

Frequently Asked Questions

How does the 80% AFUE furnace compare to high-efficiency models for long-term savings? +

An 80% AFUE furnace converts four-fifths of gas energy into heat, while 95% AFUE models waste only 5%. In cold climates heating 9+ months yearly, the efficiency gap costs $300-600 annually in additional gas. In milder regions, the difference shrinks to $100-200 yearly, making 80% AFUE acceptable.

Can I install this system in my existing ductwork without modifications? +

Possibly, but verify three factors first: duct diameter matches the 1200 CFM maximum airflow capacity, existing flue venting infrastructure supports metal requirements, and the horizontal A-coil physically fits your space. Have a technician perform a load calculation before assuming compatibility.

Why is the cooling rated at 23,600 BTU but marketed as 2 Ton? +

The specs list 3 Ton tonnage with 23,600 cooling BTU, which is approximately 2 tons. This discrepancy suggests possible data entry errors in the specification sheet. Verify actual tonnage with the distributor before purchasing to ensure proper sizing for your home.

How does the two-stage furnace burner improve comfort compared to single-stage units? +

Two-stage burners modulate between low and high capacity based on temperature demand. Low stage runs 65-75% of maximum output on mild days, reducing on-off cycling, maintaining steadier indoor temperatures, and minimizing temperature swings that feel uncomfortable. Single-stage units blast full heat then shut down abruptly.

What does the 10-year warranty actually cover if my compressor fails in year 5? +

Coverage includes compressor replacement and parts labor for manufacturing defects, but excludes wear items, corrosion, and improper installation damage. Refrigerant is often separate. Review the full warranty document after registration to understand exact limits and exclusions.
