// Bottom Line
This Goodman system works best for homeowners in mixed climates who want solid heating and cooling efficiency without premium pricing. The 96% AFUE furnace and 16 SEER1 air conditioner deliver measurable energy savings, making it ideal for retrofit jobs and new construction where budget and performance matter equally.

Review

The Goodman 4-ton (actually 5-ton) gas furnace and air conditioner system is a workhorse unit designed for residential comfort without premium pricing. This upflow configuration combines a 100,000 BTU furnace with 48,000 BTU cooling capacity, making it suitable for homes in moderate to cold climates. Energy Star certification backs the efficiency claims, and the two-stage design on both heating and cooling sides demonstrates Goodman's commitment to balancing performance with operational costs.

Where this system shines is efficiency. The furnace hits 96% AFUE, meaning 96 cents of every heating dollar converts to usable heat, while the air conditioner delivers 16 SEER1 cooling efficiency. The scroll compressor with two-stage modulation runs cooler and quieter than single-stage alternatives, and the ECM blower motor adjusts speed automatically to match demand. At 1,600 CFM maximum airflow, the unit handles both upflow and downflow configurations, offering installation flexibility.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency reduces heating costs significantly compared to 80-90% units
  • 16 SEER1 cooling rating exceeds most mid-range systems and qualifies for Energy Star certification
  • Two-stage burners and compressor modulate output for quieter operation and better comfort control
  • Multi-speed ECM blower motor handles up to 1,600 CFM with flexible airflow configuration
  • PVC plastic exhaust capability simplifies venting in retrofit applications
  • 10-year warranty with online registration provides solid consumer protection

Cons

  • 74 dB noise level on cooling cycles audible to nearby occupants during peak operation
  • Spec confusion in listing: header claims 4 ton and 15 SEER but actual specs show 5 ton and 16 SEER1
  • Requires minimum 27.7 amp breaker and proper line sizing, adding installation complexity

Who Should Buy

Best For

Homeowners replacing aging furnaces who want a dependable matched system with above-average efficiency ratings at reasonable cost. Contractors handling residential retrofits will appreciate the PVC flue compatibility and straightforward two-stage staging.

Consider Alternatives If

Buyers prioritizing ultra-quiet operation should explore variable-speed units, as 74 dB is moderately loud for cooling cycles.

Installation

Installation requires careful electrical planning. The 45 amp maximum breaker size and 27.7 amp minimum demand mean proper circuit design is essential. The unit weighs 73 pounds, manageable by two technicians, but the A-coil style and upflow configuration demand correct ductwork alignment. PVC plastic exhaust compatibility simplifies venting in many homes, but suction and liquid line sizing must match the 7/8 inch and 3/8 inch specifications exactly.

Warranty & Reliability

Goodman backs this system with 10 years of parts coverage when you register online, a consumer-friendly approach that protects your investment during the critical years when major failures typically occur. The extended warranty differentiates Goodman from budget competitors but trails premium brands offering 12-15 year coverage. Registration is straightforward and recommended immediately after installation.

Frequently Asked Questions

Does this 5-ton system oversize my home? +
The specs show 5 tons cooling and 100,000 BTU heating capacity. Verify your actual load with a Manual J calculation. Oversizing reduces efficiency and causes short cycling, so right-sizing matters. Goodman offers smaller models if your load runs 3-4 tons.
Can I install this in a crawlspace or attic? +
Yes, both upflow and downflow configurations work. The 30 inch height fits most crawlspaces, but verify clearance for the 21 by 21 inch footprint. Attic installation requires proper return air ducting and adequate ventilation for the plastic PVC exhaust.
How much does the 96% AFUE save versus standard 80% efficiency? +
On 100,000 BTU output, you recover 96,000 BTU versus 80,000 BTU from equivalent input. Over a heating season, this translates to roughly 15-20% lower gas bills depending on climate, runtime hours, and local gas rates.
Is 16 SEER1 better than 15 SEER2 from other brands? +
SEER1 and SEER2 use different rating standards. SEER2 typically scores 10-15% lower than equivalent SEER1 ratings. A 16 SEER1 unit roughly matches 13-14 SEER2 performance, so compare actual SEER2 numbers when evaluating competitors.
What does the 10-year warranty actually cover? +
Parts replacement for manufacturing defects, excluding wear items like bearings and contactors. Labor and refrigerant are typically not covered. Online registration is required within 30 days of installation to activate the full term.
