Review
The Goodman 3-ton combo system represents solid middle-market positioning in the HVAC replacement category. At $736, this upflow unit bundles a furnace and air conditioning coil in one intelligent package. Goodman occupies the sweet spot between budget builders and premium brands, trusted by contractors for reliable performance without luxury pricing. This particular SKU (LS38783850) has gained traction with homeowners upgrading 15 to 20-year-old equipment in moderate climates.
Performance numbers tell the real story. The furnace delivers 96% AFUE efficiency with 36,000 BTU output, using a single-stage gas burner and 208/230V single-phase power. The AC side matches at 36,000 BTU cooling with 14 SEER rating and scroll compressor technology. A multi-speed blower handles airflow from zero to 1,600 CFM, allowing the system to adapt to your home's demands. ENERGY STAR certification confirms it meets federal efficiency thresholds without premium pricing.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means minimal gas waste and lower heating bills in winter months
- 14 SEER cooling efficiency qualifies for ENERGY STAR certification, reducing summer energy costs
- 3-ton capacity with 36,000 BTU heating and cooling handles most single-family homes adequately
- Multi-speed blower motor adjusts airflow from 0 to 1,600 CFM for better comfort and efficiency
- 10-year warranty with online registration provides solid long-term protection on parts
- Plastic PVC flue compatibility simplifies venting in many existing installations
Cons
- Single-stage burner and compressor limit modulation, meaning the system runs at full capacity or off rather than adjusting mid-cycle
- 73 dB noise level is moderately loud for the condenser, noticeable in quiet residential neighborhoods
- R410A refrigerant is now being phased out in favor of R32 and R454B, potentially affecting future service availability
Who Should Buy
Best For
Homeowners with existing upflow ductwork replacing a failed furnace-AC combo, especially those in moderate climates where both heating and cooling receive regular use. Contractors doing bulk replacements on budget-conscious jobs will appreciate the value and straightforward installation requirements.
Consider Alternatives If
Anyone needing variable-capacity heating for extreme cold climates should look at two-stage furnaces, and those prioritizing whisper-quiet operation may want to explore higher-end units.
Installation
Installation is straightforward for upflow applications with existing ductwork. The unit dimensions are compact at 30 inches tall by 21 inches wide and deep, fitting most utility closets and basements. Right-side flue placement and PVC venting compatibility simplify exhaust routing. Electrical requirements demand a 19.1 to 30-amp breaker at 208/230V single phase. Standard sweat connections (3/8 inch liquid, 7/8 inch suction) use common copper line sizing.
Warranty & Reliability
The 10-year parts warranty requires online registration and covers manufacturing defects in the heat exchanger, compressor, and coil. This is Goodman's standard offering, not industry-leading but respectable. Covers the scroll compressor, which is the most expensive single component to replace. Does not cover labor, refrigerant, or damage from improper installation.
