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

// Bottom Line

This Goodman system works best for contractors and homeowners replacing older equipment in moderate climates where 80% AFUE and 14 SEER meet local code requirements. At $2,071, it delivers solid performance without premium pricing, making it ideal for budget-conscious replacements rather than high-efficiency retrofits.

Review

The Goodman 5-ton gas furnace and air conditioner combo represents practical equipment for residential HVAC replacements. Manufactured by Online Supply under SKU LS38783830, this upflow configuration delivers 80,000 BTU heating and 60,000 BTU cooling in a compact 30 by 24.5 by 21-inch footprint. Goodman's reputation for durability and widespread parts availability makes this system familiar to most HVAC contractors nationwide.

Performance specs show an 80% AFUE furnace with two-stage burners and a 14 SEER air conditioner using scroll compressor technology. The variable-speed blower pushes up to 2,000 CFM across the A-coil, adapting to load changes for better comfort. Electrical requirements stay modest at 120V single-phase with 32.8 to 50-amp breaker sizing, simplifying installation in standard residential panels.

Pros & Cons

Pros

14 SEER cooling efficiency is respectable for a single-stage unit, delivering 60,000 BTU cooling capacity
Two-stage furnace burner optimizes heating between 80% AFUE baseline and peak output of 80,000 BTU
Variable-speed blower motor with 2,000 CFM maximum airflow improves comfort and air distribution
Scroll compressor technology proven reliable and quiet at 75 dB noise level
$2,071 price point is competitive for a complete 5-ton combo system
10-year warranty with online registration provides adequate coverage for parts and labor

Cons

80% AFUE falls below modern 95%+ standards, missing Energy Star certification and higher efficiency rebates
Single-stage cooling limits modulation in variable load conditions, less efficient than two-stage compressors
Not SEER2 rated, making direct comparison with newer systems difficult for informed buyers
R410A or R22 refrigerant options suggest older design generation versus R32 alternatives

Who Should Buy

Best For

Contractors managing residential replacements in areas without aggressive efficiency mandates will appreciate the straightforward installation and proven Goodman platform. Homeowners in moderate climates seeking reliable heating and cooling without stretching budgets find good value here.

Consider Alternatives If

Skip this system if your region requires 90%+ AFUE or 16+ SEER, or if you plan to stay 15+ years and want maximum operating savings.

Frequently Asked Questions

Why does this unit show both R410A and R22 refrigerant options? +

This reflects older system design flexibility. R410A is standard for new installations, while R22 notation supports legacy retrofit compatibility. Specify R410A for all new systems. Confirm with your supplier which refrigerant ships with your unit before installation.

Will this furnace work with my existing ductwork designed for 2,000 CFM? +

Yes. The variable-speed blower maxes at 2,000 CFM, matching most residential duct systems. However, actual CFM depends on filter restriction and duct design. Have an HVAC tech verify static pressure remains under 0.5 inches of water column for efficiency.

How does 80% AFUE compare to other budget furnaces? +

It's baseline for economy models. Mid-range units hit 90-92% AFUE, and premium systems reach 95%+. At 80%, expect roughly 20% higher gas consumption versus 95% AFUE over a heating season, reducing long-term savings potential.

Is 14 SEER competitive with modern air conditioners? +

Fourteen SEER is good for budget systems but trails current standards. Newer units reach 16-18 SEER or higher. This unit remains solid for moderate climates, though homeowners in hot regions might prefer higher efficiency despite higher upfront cost.

Does the 10-year warranty cover refrigerant leaks? +

The warranty covers defects in the compressor and coil causing leaks. It does not cover improper charging or line damage from installation. Check your supplier's specific warranty document for exact exclusions and claim procedures.
