Review
Goodman's 3-ton combination system sits in the practical middle ground of residential HVAC. This particular unit, sold through Online Supply under SKU LS38783830, replaces older GSX130 series condensers and pairs effectively with standard furnaces. At $647, it targets homeowners who prioritize reliability and reasonable efficiency over cutting-edge performance. Goodman equipment dominates contractor installations across North America precisely because it balances solid engineering with accessible pricing.
The furnace delivers 100,000 BTU heating capacity at 80% AFUE with two-stage burners that ramp output based on temperature demand. Cooling pulls 36,000 BTU at 13 SEER through a single-stage reciprocating compressor using R410A or R22 refrigerant. The variable-speed blower motor adapts airflow up to 2000 CFM, preventing energy waste on mild days. These numbers translate to moderate monthly heating costs and respectable cooling performance without the premium efficiency price tag.
Pros & Cons
Pros
- 80% AFUE furnace efficiency with two-stage burners for better comfort and lower heating bills
- 13 SEER cooling matches mid-tier air conditioning efficiency standards without Energy Star premium
- Variable-speed blower motor maximizes comfort by adjusting output to actual heating/cooling demand
- Compact upflow A-coil design fits tight spaces, 30 inches tall by 21 inches wide
- Two-stage burner operation reduces short-cycling and extends equipment lifespan
- 10-year warranty with online registration covers manufacturing defects adequately
Cons
- Single-stage compressor in cooling side means less precise temperature control than variable-capacity units
- 80% AFUE is respectable but not premium, missing 90%+ efficiency that newer condensing furnaces offer
- 74 dB operating noise is moderately loud, noticeable in quiet living spaces
- Not Energy Star certified, so no utility rebates or tax credits available
Who Should Buy
Best For
Homeowners replacing failed equipment in moderate climates who need reliable performance without premium pricing. DIY-comfortable contractors installing systems for budget-conscious clients will appreciate the straightforward specifications and standard refrigerant compatibility.
Consider Alternatives If
Buyers in extremely cold climates needing maximum heating efficiency or those seeking premium features like variable-stage cooling and quieter operation should look at higher-SEER alternatives.
Installation
This upflow A-coil configuration requires standard 3/8-inch liquid lines and 7/8-inch suction lines with 3/8-inch insulation thickness. Electrical demand sits between 19.1 and 30 amps at 120V single-phase 60Hz, well within typical home service. The 30-inch height allows installation in most basements and attics. Metal exhaust flue is required for safe operation. Refrigerant line length capacity reaches 30 feet.
Warranty & Reliability
Goodman covers this system for 10 years against manufacturer defects when you register online, which takes five minutes on their website. Registration is mandatory to activate the full term, otherwise coverage drops significantly. This timeframe is industry standard for mid-range equipment. Parts replacement is typically available within one week from major suppliers.
