Review
Goodman's 5-ton dual-fuel system positions itself as a high-efficiency solution for contractors and homeowners seeking strong performance in mixed climates. The combination of gas heating and refrigerant cooling in one matched pair addresses a common market need, particularly for properties experiencing genuine peaks in both seasonal demands. At the stated $89 price, this appears to be a component-level cost rather than fully installed system pricing, which requires clarification before purchase.
The specifications tell an efficiency story: the furnace achieves 96% AFUE through condensing technology that captures heat from exhaust gases, while the air conditioner delivers 18 SEER2 via a two-stage scroll compressor and optimized coil design. The variable-speed ECM blower motor adapts output from zero to 2000 CFM, reducing runtime energy consumption compared to fixed-speed alternatives. Two-stage operation on both heating and cooling allows modulated capacity, though single-stage equipment sometimes outperforms on efficiency during extreme weather when maximum capacity runs continuously.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means 96 cents of every heating dollar converts to usable warmth, among the highest available for gas furnaces
- 18 SEER2 cooling efficiency significantly reduces summer energy bills compared to standard 14-16 SEER2 units
- Two-stage burner and two-stage compressor allow modulated operation, reducing energy waste during partial load conditions
- Variable-speed ECM blower motor optimizes airflow from 0 to 2000 CFM, improving comfort and efficiency
- Energy Star certified with manufacturer rebates available, lowering net installed cost
- Lifetime heat exchanger warranty plus 10-year parts coverage with online registration provides long-term peace of mind
Cons
- 5-ton capacity is oversized for many single-family homes, leading to short cycling and reduced efficiency if not properly matched to load
- Two-stage heating limits modulation during mild weather, losing some efficiency benefits versus modulating furnaces
- 71 dB noise level is moderately loud for outdoor operation, potentially concerning for noise-sensitive installations
- Requires licensed technician for installation due to gas connections and venting complexity, adding $1500-2500 to total system cost
Who Should Buy
Best For
Homeowners in cold climates replacing 15+ year old systems who need both substantial heating capacity and efficient cooling. This system works well for larger homes or those with variable heating/cooling demands across seasons.
Consider Alternatives If
Small homes under 1500 square feet should look at 3-ton or 4-ton alternatives to avoid efficiency losses from oversizing. Budget-conscious buyers uncomfortable with professional installation costs should consider simpler, lower-capacity units.
Installation
This gas furnace absolutely requires a licensed HVAC technician for safe installation. Improper gas line connections, flue venting errors, or electrical configuration can result in dangerous carbon monoxide leaks or combustion hazards. Expect professional installation to take 6-8 hours and cost $1500-2500 depending on regional labor rates and existing ductwork condition. Many jurisdictions mandate licensed installation for liability and code compliance reasons.
Warranty & Reliability
Coverage includes a lifetime heat exchanger warranty against defects plus 10 years of parts protection when registered online within 30 days of installation. The heat exchanger warranty is industry-leading and reflects Goodman's confidence in build quality. However, this covers manufacturing defects only, not wear from hard water scaling, improper maintenance, or installation errors. Registration is essential to activate benefits.
