Review
This 3-ton Goodman combination system pairs a gas furnace with an air conditioner condenser, designed as a direct replacement for discontinued GSX models. The upflow A-coil configuration fits standard attic or closet installations common in residential construction. At the entry-level efficiency tier, it appeals to budget-conscious homeowners and contractors who prioritize proven Goodman reliability over cutting-edge variable-capacity features.
The 96% AFUE gas furnace with single-stage burner converts heating fuel to usable warmth with minimal waste, while the 13 SEER condenser achieves 36,000 BTU cooling output. The reciprocating compressor runs at 115V single-phase power with a 19.1 to 30-amp circuit requirement, making electrical upgrades unnecessary in most homes. Multi-speed blower control addresses moisture removal better than fixed-speed alternatives, though the 74 dB noise level registers as audible during full operation.
Pros & Cons
Pros
- 96% AFUE gas furnace minimizes heating fuel waste with excellent combustion efficiency
- 13 SEER cooling efficiency reduces summer operating costs compared to older equipment
- 3.5-ton capacity handles mid-size homes with 36,000 BTU cooling and 80,000 BTU heating output
- Single-stage reciprocating compressor is field-proven and parts availability is strong
- Multi-speed blower motor allows better dehumidification and comfort control versus single-speed alternatives
Cons
- Not Energy Star certified, so no federal tax credits apply
- Single-stage cooling compressor lacks variable capacity for more efficient partial-load operation
- 74 dB noise level is louder than variable-speed competitors, noticeable during operation
- Requires plastic PVC exhaust flue, limiting some installation scenarios
- R22 refrigerant option complicates service costs and future availability
Who Should Buy
Best For
Homeowners replacing failed Goodman GSX130362, GSX130363, or GSX130365 units will appreciate the direct compatibility and 10-year warranty registration protection. Contractors seeking cost-effective replacements in moderate climates where single-stage simplicity and proven reliability outweigh advanced efficiency features.
Consider Alternatives If
Buyers in hot climates, those pursuing Energy Star rebates, or homes with noise-sensitive locations should evaluate variable-speed alternatives with SEER2 16+ ratings.
Installation
The upflow A-coil design suits attic or vertical closet placement with right-side flue exit requiring PVC piping. Suction and liquid line sizes measure 7/8 inch and 3/8 inch respectively, with 3/8-inch insulation thickness specified. Sweat-type refrigerant connections require brazing experience. Standard ductwork compatibility applies, though the 2,000 CFM maximum airflow should be verified against existing trunk lines.
Warranty & Reliability
Goodman provides 10 years parts coverage when owners complete online registration within specified timeframes. This non-transferable warranty protects against manufacturing defects but excludes normal wear, refrigerant loss, and installation errors. Registration documentation should be filed immediately at purchase to secure coverage eligibility.
