Review
Goodman's 3-ton combo system represents a practical middle ground in the entry-level HVAC market. This upflow configuration ships as a complete unit combining a gas furnace and air conditioner, simplifying the installation process for contractors. At $647, it undercuts premium brands while maintaining decent efficiency ratings. The system handles both heating with a 100,000 BTU furnace and cooling with 36,000 BTU capacity, making it suitable for average-sized homes in moderate climates.
The 14 SEER cooling efficiency meets minimum federal standards but trails newer systems achieving 16-18 SEER. The 80% AFUE furnace rating means 20% of heating energy becomes flue loss, a significant drawback compared to 90-95% AFUE condensing models. However, the two-stage burner provides operational flexibility, and the multi-speed blower motor optimizes comfort at 2000 CFM maximum output. The single-stage scroll compressor uses R410A or R22 refrigerant, with modest 73 dB noise levels during cooling operation.
Pros & Cons
Pros
- Excellent value at $647 for a complete 3-ton combo system with 14 SEER rating
- Two-stage burner provides better heating control and efficiency than single-stage alternatives
- High-efficiency multi-speed blower motor with 2000 CFM maximum airflow for better comfort
- Compact 21x30x21 inch footprint fits standard closets and utility spaces
- 10-year warranty with online registration covers parts and labor in most cases
Cons
- 80% AFUE is dated by modern standards, costing $200-400 more annually than 95% AFUE systems
- 73 dB noise level runs louder than higher-efficiency units, noticeable during operation
- Single-stage compressor cycles on-off rather than varying capacity, reducing part-load efficiency
Who Should Buy
Best For
This system suits homeowners replacing older equipment who prioritize upfront cost savings over long-term energy bills, and contractors serving price-sensitive customers in areas without harsh winters. It's ideal for existing homes with adequate ductwork that don't require premium performance.
Consider Alternatives If
Skip this if you live in a cold climate requiring frequent heating, want Energy Star certification, or plan to stay in your home 15+ years where higher efficiency would pay for itself.
Installation
Installation requires standard mechanical skills and HVAC knowledge. The system needs a metal exhaust flue, 120V single-phase 60Hz power, and 18.7-30 amp circuit breaker. Liquid and suction lines measure 3/8 inch and 3/4 inch respectively, with matching valve sizes. The 3/4 inch suction line insulation extends 30 feet, providing adequate coverage for most installations. Upflow configuration suits attic or closet placement in single-story homes.
Warranty & Reliability
Goodman backs this unit with a 10-year parts and labor warranty after online registration. This standard coverage protects against manufacturing defects and compressor failure, though coverage varies by retailer and installation method. Always register immediately upon purchase to activate the full term. Extended warranties typically cost $150-300 and add minimal value given the standard coverage length.
