Review
The Goodman 4 Ton combo system delivers a straightforward approach to home comfort without flashy features or premium pricing. This upflow-configured unit pairs an 80,000 BTU gas furnace with a 48,000 BTU air conditioner, making it suitable for typical 3 to 4-bedroom homes. SKU LS381183850 represents the practical middle ground in residential HVAC, offering established Goodman reliability alongside modest efficiency improvements over older equipment.
Performance metrics show solid mid-tier capability. The furnace reaches 80% AFUE with two-stage burning, improving on older 78% models. The air conditioner delivers 13 SEER cooling efficiency using R410A or R22 refrigerant, meeting current minimums but trailing premium options. A high-efficiency multi-speed blower motor maximizes the 2000 CFM airflow, adjusting output to actual heating and cooling demand rather than running full blast constantly.
Pros & Cons
Pros
- 80% AFUE furnace with two-stage burners reduces heating costs compared to 78% models
- 13 SEER air conditioner meets current minimum standards with single-stage reciprocating compressor
- High-efficiency multi-speed blower motor adjusts to actual heating and cooling demand
- 80,000 BTU heating output handles most residential heating loads effectively
- 10-year warranty with online registration provides decent coverage for parts and labor
Cons
- 13 SEER is entry-level efficiency, not Energy Star rated, meaning higher cooling costs than 16+ SEER units
- Single-stage compressor cycles on and off rather than varying output, reducing comfort and efficiency
- 76 dB noise level runs louder than high-efficiency models, noticeable during operation
Who Should Buy
Best For
Budget-conscious homeowners replacing 15+ year old systems who prioritize affordability over premium efficiency ratings. This works well for moderate climates where heating and cooling loads are balanced throughout the year.
Consider Alternatives If
Buyers in extreme climates, those seeking ENERGY STAR certification, or homeowners planning 20+ year ownership who'd benefit from higher SEER/AFUE models.
Installation
Installation requires standard connections: 3/8 inch liquid line, 1 1/8 inch suction line with half-inch insulation, and 3/8 inch sweat valves. Electrical setup needs 120V single-phase power with 26.3 to 45 amp breaker sizing. Metal exhaust flue is mandatory. Upflow/downflow A-coil configuration fits most residential installations without unusual ductwork modifications.
Warranty & Reliability
Online Supply provides a 10-year warranty when you register the unit after installation. Coverage includes parts and labor for both heating and cooling components. This mid-range warranty is competitive for equipment at this price point, though premium brands sometimes extend to 12 or 15 years. Registration is straightforward and required to activate full protection.
