Review
Goodman's 5-ton combination system pairs a gas furnace with an air conditioning condenser to deliver complete climate control in one coordinated unit. The SKU LS381183850 configuration provides 120,000 BTU heating and 54,000 BTU cooling capacity, making it suitable for homes around 2,000 to 2,500 square feet. As an Online Supply offering, this system represents mainstream commercial HVAC equipment trusted by contractors nationwide, though it lacks the premium branding of some competitors.
Efficiency is where this system truly shines. The furnace reaches 96% AFUE, meaning 96 cents of every heating dollar converts to usable warmth, with two-stage burners allowing precise heat modulation. The air conditioner delivers 16 SEER1 cooling efficiency using R410A refrigerant, earning ENERGY STAR certification. The variable-speed ECM blower motor at 2,000 CFM maximum adjusts continuously, reducing runtime and electricity consumption while maintaining comfort in upflow installations.
Pros & Cons
Pros
- 96% AFUE heating efficiency reduces natural gas costs substantially compared to 80% systems
- 16 SEER1 cooling rating qualifies for ENERGY STAR with R410A refrigerant flexibility
- Two-stage burner and variable-speed ECM blower motor enable quieter, more precise operation
- PVC exhaust flue compatibility simplifies venting in modern homes without metal chimneys
- 10-year warranty with online registration provides solid coverage for parts and labor
Cons
- 73 dBA noise level is moderately loud, especially during peak heating cycles
- Single-stage compressor limits cooling modulation compared to two-stage alternatives
- SEER1 rating of 16 trails premium units at 18+, affecting summer efficiency gains
Who Should Buy
Best For
Homeowners in cold or mixed climates needing furnace replacement will appreciate the 96% AFUE efficiency and two-stage heating. Budget-conscious contractors installing complete systems in standard residential applications find this unit's combination of performance and price highly competitive.
Consider Alternatives If
Buyers prioritizing ultra-quiet operation or maximum cooling efficiency should explore higher-SEER units with variable-capacity compressors.
Installation
Installation requires 115V single-phase power with a 29.6 to 50-amp breaker, making standard residential electrical acceptable. The upflow configuration suits basements and crawlspaces with modest height constraints at 30 inches tall. PVC exhaust venting eliminates masonry chimney requirements. Refrigerant lines include 3/8-inch liquid and 1 1/8-inch suction sizing with 50-foot maximum line length and 1/2-inch suction insulation thickness.
Warranty & Reliability
The 10-year parts and labor warranty activates upon online registration with Goodman, providing comprehensive coverage for compressor and heat exchanger failures. This protects against premature component degradation but excludes routine maintenance and wear items. Registration is essential, as warranty defaults to shorter periods without proof of purchase.
