// Bottom Line

This Goodman combo system works well for homeowners replacing older equipment in moderate climates where 13 SEER performance meets code requirements. The 96% AFUE furnace and straightforward installation make it a practical choice for budget-conscious buyers seeking reliable heating and cooling without premium-tier efficiency.

Review

The Goodman 2.5-ton combo system combines a gas furnace and air conditioner in a single upflow configuration designed for tight spaces and straightforward replacement installations. At the entry-level of today's market, this unit delivers adequate performance for homeowners seeking no-frills comfort without investing in premium efficiency tiers. The 40,000 BTU heating output and 30,000 BTU cooling capacity fit typical mid-sized homes across moderate climates.

This system pairs a 96% AFUE furnace with a 13 SEER air conditioner, positioning it solidly in the budget segment. The furnace's high annual fuel utilization efficiency minimizes heating waste, while 13 SEER meets federal minimum cooling standards without premium features. Single-stage operation, a reciprocating compressor, and standard R410A refrigerant support keep maintenance straightforward. The 115V electrical requirement and 16.7 to 25 amp breaker range suit typical residential panels without upgrades.

Pros & Cons

Pros

96% AFUE furnace efficiency reduces heating costs compared to older 80-85% AFUE systems
13 SEER cooling rating meets federal minimum standards, providing modest AC efficiency
Single-stage reciprocating compressor delivers predictable, low-maintenance operation
A-coil design with 800 CFM multi-speed blower fits standard upflow/downflow installations
10-year parts warranty with online registration provides reasonable protection against manufacturing defects

Cons

13 SEER is entry-level efficiency, trailing 16+ SEER high-efficiency models by 20-30% in cooling energy use
Single-stage cooling means compressor cycles on/off rather than modulating, reducing comfort in mild weather
73 dB noise level at full capacity may be noticeable in quiet homes or bedrooms

Who Should Buy

Best For

Homeowners in moderate climates replacing 10-20 year old systems who prioritize upfront cost over long-term energy savings. Contractors building affordable replacement packages for price-sensitive customers in areas with moderate cooling demands.

Frequently Asked Questions

How does 13 SEER compare to newer high-efficiency systems? +

13 SEER meets federal minimum standards but lags 16-18 SEER systems by roughly 20-25% in seasonal cooling efficiency. Over 15 years, homeowners in hot climates could pay $3,000-5,000 more in electricity. Best for mild climates or shorter-term ownership.

Will this fit my existing ductwork and furnace location? +

The compact 22x17.5x21 inch A-coil footprint fits most standard return plenums. Upflow/downflow versatility handles both basement and attic installations. Verify your suction and liquid line routing can accommodate the 3/8 inch and 3/4 inch connections before ordering.

Why is it single-stage instead of two-stage? +

Single-stage operation cuts manufacturing and component costs by running the compressor at full capacity or off. Two-stage systems modulate output for quieter, steadier operation. This unit cycles more frequently, which may affect comfort and electricity use on mild days.

Is R410A refrigerant a concern as EPA phases it out? +

The spec lists R410A or R22 compatibility. R410A remains legal for new installations through 2030. R22 is expensive and outdated. Stick with R410A for this system and avoid phaseout headaches. Plan future replacement around 2025-2030 if that matters to you.

What does the 10-year warranty actually cover? +

Parts defects including compressor, heat exchanger, and coil failures are covered for 10 years with registration. Labor is typically excluded. Terms vary by supplier, so confirm details before purchase and register promptly.
