Review
The Goodman 5-ton gas furnace and air conditioner system represents the practical middle ground in residential HVAC equipment. With a 54,000 BTU cooling capacity and 80,000 BTU heating output, this unit handles most single-family homes effectively. Online Supply's SKU LS381183850 attracts contractors who value proven Goodman reliability without premium pricing. The ENERGY STAR certification signals acceptable efficiency for buyers seeking balanced performance.
Performance metrics are straightforward and competitive. The air conditioner achieves 16 SEER2 efficiency with a scroll compressor operating at single-stage compression, delivering 2,000 CFM maximum airflow. The furnace provides 80% AFUE efficiency with two-stage burners, meaning 80 cents of every heating dollar convert to usable heat. Electrical requirements are modest at 120V single-phase 60Hz with a 29.6 to 50-amp breaker range, simplifying electrical work on most residential panels. The system uses R410A refrigerant and accepts 3/8-inch liquid and 1 1/8-inch suction lines with standard 1/2-inch insulation.
Pros & Cons
Pros
- 16 SEER2 rating beats the spec sheet claim and qualifies for ENERGY STAR certification
- Two-stage burner with 80,000 BTU heating capacity handles cold climates effectively
- High-efficiency multi-speed blower motor maximizes comfort while reducing runtime cycles
- Compact A-coil design fits tight spaces with modest 21 by 21 inch footprint
- 10-year compressor warranty provides meaningful coverage with online registration
Cons
- 80% AFUE is acceptable but trails high-efficiency condensing furnaces at 95%+ AFUE
- Single-stage cooling compressor cycles on and off rather than modulating for precision
- 73 dB noise level at maximum output may concern noise-sensitive homeowners
Who Should Buy
Best For
Contractors and homeowners replacing aging systems in moderate climates who prioritize reliability and reasonable upfront cost over premium efficiency. This system suits homes where natural gas heating is primary and cooling handles summer loads predictably.
Consider Alternatives If
Buyers in extreme climates, those chasing maximum efficiency rebates, or homeowners with strict noise restrictions should explore variable-capacity or condensing alternatives.
Installation
Installation requires metal exhaust flue venting for the furnace, metal ductwork connection, and proper lineset routing with the provided 50-foot insulated suction line. The compact 21 by 21 by 30-inch condenser and upflow A-coil configuration fit basements, crawlspaces, and mechanical closets with minimal clearance issues. Licensed technicians typically complete installation in four to six hours for standard installations without major ductwork modifications.
Warranty & Reliability
The 10-year compressor and parts warranty activates upon online registration and provides solid protection against manufacturing defects. Goodman's evaporator coil carries separate coverage noted in documentation. This warranty is standard for mid-tier equipment and offers meaningful peace of mind, though premiums models sometimes extend to 12 years.
