Review
Goodman has built its reputation on delivering competent HVAC equipment at accessible pricing, and this 3-ton system proves the formula works. The 16 SEER air conditioner and 96% AFUE furnace combination positions it firmly in the energy-efficient category without entering premium territory. SKU LS38783850 is an upflow configured unit designed for typical residential installations where ducting runs vertically from a basement or utility closet.
The heating side produces 120,000 BTU with two-stage burner operation and variable-speed ECM blower motor that can push up to 2,000 CFM. Cooling delivers 34,800 BTU using a scroll compressor with R410A refrigerant and single-stage operation. The 96% AFUE rating means only 4% of fuel energy is lost, translating to heating costs roughly 12-15% lower than 85% AFUE equipment. The 16 SEER1 efficiency rating meets Energy Star criteria and supports midrange utility savings.
Pros & Cons
Pros
- 96% AFUE heating efficiency reduces natural gas or propane consumption significantly compared to 80-90% units
- 16 SEER cooling rating qualifies as Energy Star and delivers solid cooling efficiency for the price point
- Variable-speed ECM blower motor adjusts airflow automatically, improving comfort and reducing runtime costs
- Two-stage burner provides better heating modulation and less temperature swinging than single-stage alternatives
- 10-year warranty with online registration covers parts and labor comprehensively
- PVC exhaust compatibility simplifies installation in many existing homes without expensive flue upgrades
Cons
- Single-stage condenser limits cooling modulation, meaning the unit cycles on-off rather than ramping capacity smoothly
- 73.5 dB operating noise falls within acceptable range but louder than premium variable-capacity systems
- 3-ton cooling paired with 5-ton equivalent heating creates minor sizing mismatch for homes with balanced seasonal demands
Who Should Buy
Best For
Homeowners in mixed climates replacing 15-20 year old furnace and AC systems who prioritize operating cost reduction and value reliable mid-tier equipment. Contractors looking for dependable equipment that installs straightforwardly and carries reasonable warranty backing.
Consider Alternatives If
Buyers in extreme climates needing matched tonnage across heating and cooling, or those seeking variable-capacity compressors for maximum efficiency should explore higher-tier offerings from Goodman or competitors.
Installation
This system requires 208/230V single-phase 60Hz electrical service with breaker sizing between 18.7 and 30 amps, standard in most homes. PVC exhaust flue compatibility eliminates expensive metal flue replacements in many installations. Upflow configuration suits typical basement or utility room placement. Suction line insulation (3/4 inch) and 50-foot maximum line length accommodate most residential layouts without special modifications.
Warranty & Reliability
Goodman backs this unit with a solid 10-year parts and labor warranty provided you complete online registration after purchase. Coverage includes compressor, condenser coil, and furnace components. The A-coil evaporator carries separate extended warranty documentation. This warranty level represents middle-market protection, falling behind premium brands but exceeding builder-grade equipment typically bundled with new construction.
