Review
The Goodman 3-ton gas furnace and air conditioner system (SKU LS38783830) is a straightforward choice for homeowners balancing comfort needs with budget constraints. Manufactured by Goodman and distributed through Online Supply, this upflow unit combines a gas furnace with an air conditioner in a single integrated package. It replaces earlier GSX130 series models and targets the mid-market segment where efficiency matters but premium features aren't required. The A-coil configuration and upflow airflow direction make it suitable for attic or closet installations in most residential applications.
Performance specifications tell a practical story here. The furnace delivers 80,000 BTU of heating output at an impressive 96% AFUE rating, meaning nearly all fuel converts to usable heat with minimal exhaust loss through the PVC flue. On the cooling side, expect 36,000 BTU and 13 SEER efficiency, which ranks decent but not exceptional. The multi-speed blower reaches 1200 CFM maximum, allowing flexibility in airflow management. The reciprocating compressor and single-stage operation mean this system runs full-bore or idle, sacrificing the modulating efficiency of more advanced units but keeping service costs lower.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means lower winter heating bills and minimal energy waste through the PVC flue
- 13 SEER cooling provides solid seasonal efficiency, delivering 36,000 BTU of cooling capacity for 3-ton applications
- Multi-speed blower motor optimizes airflow at 1200 CFM maximum, reducing temperature swings and improving comfort
- Upflow A-coil configuration fits tight attic or closet spaces common in residential installations
- 10-year warranty with online registration provides reasonable peace-of-mind protection on parts and labor
Cons
- Single-stage compressor and burner mean the system runs at full capacity or off, lacking efficiency in mild weather conditions
- Not ENERGY STAR certified, so it misses the mark for homeowners targeting eco-friendly rebates or higher efficiency tiers
- 74 dB noise level is moderately loud during AC operation, noticeable in quieter neighborhoods or near bedrooms
Who Should Buy
Best For
Budget-conscious homeowners and landlords needing dependable heating and cooling without investing in variable-capacity systems. This works well in areas with distinct seasonal heating demands where single-stage efficiency is acceptable and where PVC exhaust venting is permissible.
Consider Alternatives If
Homeowners in warm climates seeking high cooling efficiency, or those wanting a system that modulates capacity for whisper-quiet operation in spring and fall.
Installation
Installation complexity is moderate. Electrical requirements are straightforward at 115V, single phase, 60 Hz with a 19.1 to 30-amp breaker range. Refrigerant connections use 3/8 inch liquid and 3/4 inch suction valves with sweat-type fittings, requiring competent soldering work. The 3/8 inch suction line insulation and 30-foot maximum line length keep runs manageable. Upflow configuration suits tight spaces, but proper ductwork connection and gas line installation demand licensed technician expertise.
Warranty & Reliability
Goodman backs this system with a 10-year parts and labor warranty upon online registration. Registration is essential, as you'll need to complete it to activate coverage. This warranty level is solid for the price point and covers compressor, heat exchanger, and major components. Keep your registration confirmation and service records organized for any future claims.
