5 Ton 14 SEER 80% AFUE 100,000 BTU Goodman Gas Furnace and Air Conditioner System - Upflow Review 2026

// Bottom Line

This Goodman 5-ton system is built for contractors who need balanced performance without premium pricing. It delivers solid efficiency (14 SEER, 80% AFUE) and straightforward installation, making it reliable for residential homes in moderate climates where 80% furnace efficiency is acceptable.

Review

The Goodman 5-ton combination gas furnace and air conditioner represents mainstream HVAC equipment trusted by contractors for residential replacement work. This upflow/horizontal configuration delivers 60,000 BTU cooling capacity paired with a 100,000 BTU heating stage, sized appropriately for medium homes across most climates. Online Supply markets this unit with practical engineering and strong contractor support, making it a workable choice for crews prioritizing installation speed and parts availability over cutting-edge efficiency.

Performance metrics tell a straightforward story. The 14 SEER rating on the cooling side meets post-2023 regional standards without excessive cost, while the 80% AFUE furnace sits at industry baseline for non-condensing models. The scroll compressor runs single-stage, meaning it cycles fully on and off rather than modulating capacity, which simplifies controls but reduces efficiency under partial load. Maximum airflow reaches 2000 CFM, and electrical demands stay reasonable at 32.8 to 50 amps, fitting most existing 100-amp residential service panels.

Pros & Cons

Pros

14 SEER cooling efficiency meets modern standards for most regions without ENERGY STAR complexity
Two-stage burner with 100,000 BTU heating capacity provides balanced comfort and efficiency
Scroll compressor is proven architecture with fewer failure points than rotary designs
High-efficiency multi-speed blower with up to 2000 CFM adapts to varying load conditions
Compact 30 x 21 x 21 inch footprint fits tight closets and utility spaces
10-year warranty with online registration covers manufacturer defects and coil failures

Cons

80% AFUE falls below modern 95%+ standards, resulting in higher heating costs over time
Single-stage cooling compressor cycles on/off rather than modulating capacity smoothly
Not ENERGY STAR certified, limiting appeal to efficiency-conscious buyers
75 dB noise level runs louder than inverter-driven competitors during operation

Who Should Buy

Best For

Contractors restocking inventory with reliable mid-range equipment and homeowners replacing older systems who want proven technology without premium pricing. This system works well in climates where heating costs aren't extreme and efficiency is secondary to upfront affordability.

Consider Alternatives If

Buyers seeking ENERGY STAR certification, homes in cold climates where 95%+ AFUE becomes cost-justified, or noise-sensitive installations near bedrooms.

Installation

Installation requires metal exhaust flue venting, R410A or R22 refrigerant charging, and standard lineset connections using 3/8 inch liquid line and 7/8 inch suction line with 3/8 inch factory insulation. The A-coil configuration demands upflow or downflow mounting, and the unit needs 120V single-phase power. Technicians appreciate the straightforward design, but proper airflow testing and ductwork balance remain essential for rated performance.

Warranty & Reliability

Goodman backs this system with 10 years parts coverage upon online registration, extending to the evaporator coil through their separate coil warranty program. This standard coverage protects against manufacturing defects but excludes wear items, refrigerant, and labor. Registration is required, so buyers must complete that step within 30 days to lock in the full term.

Frequently Asked Questions

How does 14 SEER compare to modern air conditioners? +

14 SEER meets current efficiency standards in most regions and costs less than 16-18 SEER units. It performs adequately for moderate climates but runs higher operating costs than inverter-driven systems in hot areas. For cooling-heavy regions, consider stepping up to higher SEER ratings if utility rebates apply.

Will this fit my existing ductwork? +

The 5-ton rating and 2000 CFM maximum capacity suit homes originally sized for 5-ton systems. However, proper duct design and airflow testing are non-negotiable. Undersized ducts will reduce efficiency significantly, so have a technician verify your return and supply ductwork diameter before purchase.

What's the difference between 80% and 95% AFUE? +

80% AFUE means 20% of fuel energy escapes as waste heat, while 95% systems lose only 5%. Over 15 years, the efficiency gap costs roughly 15-20% more on heating bills depending on local gas prices. In cold climates, the higher upfront cost of 95% systems typically pays back in 7-10 years.

How does single-stage cooling affect my comfort? +

Single-stage compressors run at full capacity or off, creating temperature swings. Two-stage or variable-capacity systems maintain steadier comfort. This unit works adequately in mild climates but feels less comfortable during shoulder seasons when partial cooling would suffice.

Is the 10-year warranty enough protection? +

Yes, it covers most component failures within that window. However, refrigerant leaks and labor aren't included. Consider adding an extended service plan if you prefer predictable repair costs beyond year five.
