Review
This Goodman 3-ton system combines a gas furnace and air conditioner in a compact downflow configuration suitable for tight equipment closets and basement installations. The unit sits squarely in the mainstream market, offering contractors a familiar choice with strong customer recognition. Online Supply's listing carries SKU LS38783830 and positions this as a direct replacement for older GSX models, making it attractive for retrofit jobs where ductwork and electrical already exist.
The heating side delivers 80,000 BTU with an impressive 96% AFUE rating, meaning minimal natural gas waste during winter operation. Cooling capacity reaches 36,000 BTU at 13 SEER, with a reciprocating compressor handling single-stage operation at 74 dB. The multi-speed blower motor maxes out at 1,600 CFM, accommodating standard residential ductwork. Electrical requirements are straightforward, needing 115V single-phase 60 Hz service with a breaker sized between 19.1 and 30 amps.
Pros & Cons
Pros
- 96% AFUE furnace efficiency exceeds most mid-range competitors, reducing heating costs significantly
- 13 SEER rating on 3-ton cooling capacity delivers solid summer performance at 36,000 BTU
- Multi-speed blower motor optimizes comfort by varying airflow based on demand
- Single-stage reciprocating compressor is proven technology with established service networks
- 10-year warranty with online registration provides solid protection on parts
Cons
- 13 SEER is respectable but trails newer 14-16 SEER systems gaining market share
- Single-stage compressor means less efficiency ramping at partial loads compared to two-stage units
- 74 dB noise level is acceptable but not whisper-quiet like premium variable-speed models
- Requires R410A or R22 refrigerant, limiting future compatibility if regulations shift
Who Should Buy
Best For
Contractors installing systems in cost-conscious residential markets will appreciate the reliable Goodman name and straightforward single-stage design. Homeowners upgrading from aging equipment and seeking balanced efficiency without premium pricing fit this system well.
Consider Alternatives If
Buyers seeking Energy Star certification, ultra-quiet operation below 70 dB, or high-efficiency SEER ratings above 15 should explore alternative brands or higher-tier Goodman models.
Installation
Installation requires plastic or PVC flue venting with the exhaust outlet positioned on the right side of the unit. Refrigerant lines need 3/8 inch suction insulation at 3/8 inch thickness for proper A-coil performance. The downflow configuration means gravity assists condensate drainage. Technicians should budget time for standard electrical connection, gas line setup, and ductwork evaluation.
Warranty & Reliability
Online Supply extends a 10-year parts warranty upon online registration, covering manufacturing defects on compressor, heat exchanger, and coil components. This is standard industry protection that motivates proper installation and maintenance. Coverage requires documenting your purchase within the registration window to activate full benefits.
