// Bottom Line
This Goodman system works best for homeowners replacing an older unit in moderate climates who want respectable efficiency without paying premium prices. The 14 SEER cooling and 80% AFUE heating make it a practical middle-ground choice for budget-conscious buyers.

Review

The Goodman 5-ton gas furnace and air conditioner combination represents a practical entry point into reliable HVAC systems. Manufactured by Online Supply under SKU LS38783830, this upflow-configured unit pairs a 100,000 BTU furnace with 60,000 BTU cooling capacity. It's positioned for homeowners and contractors seeking established brand quality without boutique pricing, occupying the middle tier of residential HVAC equipment rather than premium or budget extremes.

Performance specs show a 14 SEER cooling rating from a single-stage scroll compressor using R410A or R22 refrigerant, paired with two-stage heating and a variable-speed blower reaching 2,000 CFM maximum airflow. The 80% AFUE furnace efficiency is respectable for non-premium equipment but trails newer systems hitting 95%+. Electrical demands run 120V single-phase at 32.8 to 50 amp breaker sizing. Noise output measures 75 dBA, acceptably quiet for comfort.

Pros & Cons

  • Scroll compressor is known for durability and quieter operation at 75 dB
  • 10-year warranty with online registration provides meaningful protection

Cons

  • 80% AFUE is below modern standards; newer systems reach 95%+ efficiency
  • Single-stage cooling compressor less efficient than two-stage alternatives in variable loads
  • Not Energy Star certified, limiting appeal to efficiency-focused buyers

Frequently Asked Questions

What's the real difference between 14 SEER and newer 16+ SEER systems? +
SEER2 standards (now industry standard) would rate this unit slightly lower. A 14 SEER system costs 10-15% less but uses roughly 12-15% more electricity than 16+ SEER models. Over 10 years in moderate climates, the difference is $300-500 in cumulative utility costs.
Can I use this in cold climates with backup electric heat? +
Yes. Two-stage heating and variable-speed blower help, but 80% AFUE means significant heat loss. Very cold climates benefit more from high-efficiency 95%+ AFUE systems. This unit works adequately in zones averaging winter lows above 0°F.
How loud is 75 dB compared to other systems? +
75 dB is typical for single-stage cooling. You'll hear the compressor cycle, similar to older units. Premium two-stage systems run 72-73 dB. For most residential locations, 75 dB is acceptable during operation but noticeable if outdoor unit is near bedrooms.
Should I choose this over a higher-efficiency Lennox or Carrier? +
Not if efficiency justifies 25-35% higher cost for your scenario. Goodman scores well on reliability and value. Choose premium brands only if you're staying 15+ years or live in extreme climates where efficiency directly impacts comfort.
Is the 10-year warranty actually comprehensive? +
Covers parts and labor on major components when registered. Excludes damage from improper installation, freezing, or acid burnout. It's honest protection, not as broad as some manufacturer programs, but adequate for standard residential use.
