// Bottom Line
This Goodman system is ideal for contractors and homeowners upgrading attic or crawlspace installations where horizontal configuration is required. The 97% AFUE furnace and 16 SEER cooling deliver real energy savings in moderate to cold climates, especially for properties with natural gas or propane availability.

Review

The Goodman 5-ton horizontal system occupies a practical middle ground in the HVAC market. It combines proven furnace technology with solid cooling capacity in a configuration designed for tight spaces where traditional vertical units won't fit. At 77 pounds and measuring 24.5 inches tall, 26 inches wide, and 21.125 inches deep, it fits easily into most attic and crawlspace installations. This model targets cost-conscious contractors and homeowners seeking efficiency improvements without enterprise-level pricing.

Performance specifications tell a compelling story for heating-dominant regions. The furnace delivers 120,000 BTU at 97% AFUE, converting nearly every dollar of fuel into usable heat rather than wasting it up the chimney. Cooling output reaches 57,000 BTU with 16 SEER efficiency and two-stage compressor operation. The variable-speed ECM blower adjusts to 2,000 CFM maximum, matching output to actual heating and cooling demand rather than running at constant speed. These features meaningfully reduce energy consumption compared to older 90-93% AFUE single-stage equipment.

Pros & Cons

Pros

  • 97% AFUE furnace efficiency reduces heating costs significantly compared to 90-93% models
  • Modulating burner stages adjust heating output for better comfort and lower utility bills
  • Variable-speed ECM blower optimizes airflow while reducing fan energy consumption
  • Two-stage condenser with scroll compressor provides reliable cooling at 57,000 BTU for 5-ton capacity
  • PVC exhaust flue compatibility simplifies venting in modern construction
  • 10-year warranty with online registration covers both heating and cooling components

Cons

  • Not Energy Star certified despite high efficiency ratings
  • 16 SEER cooling rating lags behind newer 18-20 SEER competitors released in recent years
  • 74 dB noise level is moderately loud during operation, noticeable in some installations
  • Requires 36.7 to 60-amp breaker sizing, limiting some older electrical panel placements

Who Should Buy

Best For

Contractors installing horizontal systems in attics or compact crawlspaces will appreciate the proven Goodman reliability and straightforward PVC venting. Homeowners in northern climates who heat with natural gas or propane and want genuine efficiency gains without premium pricing should seriously consider this unit.

Consider Alternatives If

Skip this if you need maximum cooling efficiency above 17 SEER, prefer Energy Star certification, or have electrical service limitations below 36.7 amps.

Installation

Horizontal mounting simplifies installation in confined spaces where vertical clearance doesn't exist. The right-side flue outlet works with standard PVC or plastic venting, avoiding expensive metallic ductwork costs. Refrigerant connections use 3/8-inch liquid lines and 7/8-inch suction lines with sweat valves, allowing experienced technicians to integrate with existing copper linework. Electrical requirements demand 208/230V single-phase 60Hz service with breaker sizing between 36.7 and 60 amps.

Warranty & Reliability

Goodman backs this system with 10 years of parts and labor coverage when registered online, a solid commitment matching most mid-tier competitors. The warranty protects against compressor failure, heat exchanger defects, and blower motor problems. Online registration takes minutes and activates coverage immediately. Ten years provides genuine protection for residential applications, though commercial users should verify specific terms with the dealer.

Frequently Asked Questions

Does this system work with both natural gas and propane? +
Yes. The furnace accepts both natural gas and propane fuel, offering flexibility for homes with either supply type. Field conversion requires a qualified technician to adjust the burner assembly, so verify your gas type before installation and confirm your technician completes proper setup.
Can I install this in my attic with limited headroom? +
Absolutely. The horizontal configuration with 24.5-inch height makes it ideal for attics with seven to eight feet of clearance. The PVC flue vents horizontally through a gable or soffit vent, simplifying installation. Ensure adequate clearance around the unit for filter access and maintenance.
How does 16 SEER compare to newer systems I'm seeing advertised? +
16 SEER is respectable but not cutting-edge. Recent competitors offer 17-20 SEER ratings with variable-capacity compressors. The trade-off here is that you get solid cooling efficiency and proven reliability at lower cost, rather than maximum efficiency that takes longer to recoup through energy savings.
Will this system qualify for utility rebates? +
The listing notes rebates are available, but eligibility varies by location and utility company. Contact your local utility before purchasing, as some require ENERGY STAR certification, which this unit lacks. However, the 97% AFUE furnace often qualifies for state or regional heating efficiency incentives.
What does the 10-year warranty actually cover? +
Standard parts and labor coverage applies to the compressor, heat exchanger, blower motor, and sealed refrigerant circuit. Wear items like capacitors and contractors may have separate terms. Register online immediately to activate coverage and retain documentation for any claims.
