Review
The Goodman 3-ton combo system at $2,552 occupies the practical middle ground for HVAC replacement. It combines a 60,000 BTU furnace with matching 36,000 BTU air conditioning into one upflow-capable package. This SKU LS38783830 is AHRI certified and carries Goodman's reputation for no-nonsense equipment. Contractors and homeowners appreciate this system because it delivers solid performance without forcing premium efficiency upgrades they may not recover through energy savings within the warranty period.
Performance specs show 80% AFUE heating efficiency paired with 13 SEER cooling, a respectable combination for baseline replacement work. The variable-speed blower motor handles 1600 CFM maximum airflow, adjusting runtime to match heating or cooling demand. Two-stage burners give the furnace finer control over heat output, reducing short-cycling during mild weather. R410A refrigerant and reciprocating compressor technology are industry standard. The 208/230V single-phase electrical requirement suits typical residential panels with 19.1 to 30 amp breaker sizing.
Pros & Cons
Pros
- 60,000 BTU heating output with two-stage burner provides responsive comfort in transitional seasons
- 13 SEER cooling efficiency exceeds baseline standards, delivering 36,000 BTU cooling capacity for 3-ton systems
- Variable-speed blower motor maximizes comfort by adjusting airflow from 0 to 1600 CFM based on demand
- Dual fuel compatibility, natural gas or propane, expands installation options for rural properties
- Compact 26x26x27.5 inch footprint fits existing closet and basement installations without major retrofitting
Cons
- 80% AFUE is dated technology, missing out on 95%+ AFUE high-efficiency models that save significantly over system lifetime
- Single-stage condenser means cooling runs at full capacity until satisfied, less precise than two-stage systems
- 74 dB noise level is moderately loud during compressor operation, noticeable in quiet neighborhoods
Who Should Buy
Best For
Homeowners in temperate climates (zones 4-6) replacing 15+ year old systems who prioritize upfront affordability over peak efficiency. Contractors seeking reliable equipment for budget-conscious clients who plan to stay in homes another 10 to 15 years.
Consider Alternatives If
Energy-conscious buyers in cold climates should pursue 95% AFUE furnaces, and those in very hot climates need high-SEER equipment.
Installation
Installation requires metal exhaust flue and proper refrigerant line sizing with 3/8 inch suction insulation thickness. The compact 26x26x27.5 inch dimensions simplify retrofit work in tight spaces. Technicians need standard 3/8 inch and 3/4 inch sweat valve fittings. Propane or natural gas conversion involves minimal adjustments. Configuration supports both upflow and downflow positions, giving installers layout flexibility. Goodman provides detailed manuals and kit instructions for straightforward setup.
Warranty & Reliability
Goodman extends a 10-year parts and labor warranty when registered online. This solid coverage protects against premature compressor failure and heat exchanger defects. Registration is straightforward but required, so buyers must complete paperwork within 30 days of installation. The warranty does not cover routine maintenance, refrigerant top-ups, or damage from improper installation.
