Review
Goodman's 3-ton horizontal gas furnace and air conditioner system occupies a comfortable middle ground in the HVAC market. It targets cost-conscious homeowners and contractors who need reliable equipment without premium pricing. The horizontal configuration suits homes with basement or crawlspace layouts where traditional upflow furnaces don't fit. Online Supply positions this as a replacement option for legacy Goodman models, leveraging existing installation familiarity among service technicians.
The furnace delivers impressive heating performance with a 96% AFUE rating and 80,000 BTU output, making it genuinely efficient for winter months. Cooling comes from a reciprocating compressor pushing 36,000 BTU through an A-coil design with 13 SEER efficiency. The multi-speed blower motor rated for 1,600 CFM maximum allows contractors to balance comfort and energy use. Electrical requirements are modest, drawing between 19.1 and 30 amps at 115V single-phase, simplifying installation in homes without dedicated circuits.
Pros & Cons
Pros
- 96% AFUE furnace efficiency ranks among the best for gas heating, delivering superior warmth from every BTU burned
- 80,000 BTU heating capacity with single-stage burner is sufficient for most three-ton cooling zones
- 13 SEER cooling efficiency exceeds baseline standards, providing reasonable AC performance at competitive pricing
- Multi-speed blower motor allows flexibility in airflow control for both heating and cooling seasons
- Plastic PVC exhaust compatibility simplifies venting installation compared to metal ductwork requirements
- 10-year warranty with online registration protects against major component failures
Cons
- 36,000 BTU cooling capacity falls short of the marketed 3-ton rating, creating a mismatch between heating and cooling output
- Single-stage compressor and burner lack modulation, resulting in less efficient operation at partial loads common in spring and fall
- Not Energy Star certified, which means higher standby energy consumption than premium models
- 74 dBA noise level is louder than variable-speed competitors, potentially noticeable in quiet neighborhoods
Who Should Buy
Best For
This system suits homeowners replacing older Goodman units (GSX130362, GSX130363, GSX130365) in homes with existing ductwork designed for horizontal installation. It's ideal for those who heat more than they cool and want a straightforward, dependable system without smart controls or premium efficiency tiers.
Consider Alternatives If
Skip this model if you need balanced heating and cooling capacity, live in a hot climate requiring heavy AC use, or want quiet operation and advanced modulation features.
Installation
Installation complexity is moderate. The horizontal configuration demands careful positioning in tight spaces, and the right-side flue location must align with PVC exhaust routing. Valve sizes require 3/8 inch liquid line and 7/8 inch suction line connections with 3/8 inch insulation thickness on the suction side. Sweat valve connections need proper brazing or soldering experience. Most contractors familiar with Goodman equipment will handle this quickly, but first-timers should allocate extra time for ductwork measurements.
Warranty & Reliability
The 10-year parts warranty applies when you register online after purchase, which is standard practice in the industry. This covers compressor, heat exchanger, and major components against manufacturing defects. Labor is not included, so repair costs beyond parts fall on the homeowner. Registration is straightforward but required, so don't skip this step immediately after installation.
