Review
The Goodman 2-ton system with model LS38343850 combines a high-efficiency gas furnace with an ENERGY STAR certified air conditioner into one package. This upflow A-coil configuration appeals to contractors and homeowners seeking straightforward combo solutions. Goodman maintains strong market penetration in mid-tier equipment, and this particular SKU represents a balanced approach between performance and cost, replacing the older GSX16S241 model.
The furnace delivers 80,000 BTU output with an impressive 96% AFUE rating, coupled with a two-stage burner that optimizes efficiency across heating loads. The air conditioner provides 23,600 BTU cooling capacity at 16 SEER1, earning ENERGY STAR recognition. A scroll compressor and multi-speed ECM blower motor managing up to 1200 CFM round out the spec sheet. The 115V single-phase electrical requirement with 12.4 to 20-amp breaker sizing fits standard residential installations.
Pros & Cons
Pros
- 96% AFUE furnace exceeds most baseline standards and qualifies for some utility rebates
- Two-stage burner configuration provides better part-load efficiency and quieter operation during mild weather
- ENERGY STAR certified air conditioner with 16 SEER1 rating meets modern efficiency expectations
- Multi-speed ECM blower motor adjusts airflow from 0-1200 CFM for personalized comfort control
- Durable scroll compressor with 10-year warranty and PVC flue compatibility simplifies venting requirements
Cons
- Single-stage air conditioner lacks variable-speed cooling, limiting efficiency during partial-load conditions
- 2.5-ton cooling capacity appears oversized relative to 80,000 BTU heating output, suggesting potential mismatch in mixed-climate sizing
- 71.5 dB noise level is audible from adjacent rooms during full-capacity operation
Who Should Buy
Best For
Homeowners in climates where winter heating demands are substantial should consider this unit. It pairs excellent furnace efficiency with adequate cooling performance at a fair price, making it ideal for applications where heating costs represent the larger share of annual energy consumption.
Consider Alternatives If
Buyers in warm climates seeking maximum cooling efficiency or variable-capacity technology should look at variable-stage systems instead, as the single-stage compressor limits part-load cooling performance.
Installation
This upflow unit accepts plastic or PVC flue venting, simplifying exhaust routing in many homes. Standard 3/8-inch liquid and 3/4-inch suction line connections with 50 feet of insulated suction line included reduce field labor. The multi-position A-coil design handles both upflow and downflow installations. Contractors report straightforward integration with existing ductwork, though proper airflow verification remains essential for optimal performance.
Warranty & Reliability
Goodman provides 10 years of parts warranty when you complete online registration after purchase. This coverage applies to the compressor, blower motor, and heat exchanger. Registration extends protection but requires documentation, so homeowners should maintain proof of installation and activation dates. Ten years is competitive for this equipment tier.
