Review
The Goodman 1.5-ton gas furnace and air conditioner combo represents the practical middle ground in residential HVAC. This downflow-capable system pairs a 40,000 BTU furnace with an 18,000 BTU air conditioner to handle moderate cooling and heating loads across small homes or single zones. Online Supply positions this as a no-frills solution for contractors and homeowners tired of inflated pricing on more prestigious brands offering similar baseline performance.
Performance metrics reveal competent but unexciting efficiency. The 80% AFUE gas furnace loses one unit of energy for every five consumed, compared to 95% AFUE premium models. Cooling efficiency registers at 13 SEER, meaning this system operates roughly 20 to 30 percent less efficiently than modern 16+ SEER alternatives. The dual two-stage burner and multi-speed blower mitigate some efficiency gaps by allowing modulated operation rather than constant full-power cycling, though single-stage cooling compressor design limits cooling optimization.
Pros & Cons
Pros
- Dual-fuel compatibility supports both R410A and R22 refrigerants, useful for retrofit applications or future upgrades
- Two-stage burner on furnace allows modulating heat output, reducing cycling and improving comfort over single-stage designs
- Multi-speed blower motor with 1200 CFM maximum enables better air distribution and some efficiency optimization
- Flexible configuration handles both upflow and downflow installations, fitting various ductwork layouts
- 10-year warranty with online registration provides solid peace of mind for component failures
Cons
- 80% AFUE is competent but not exceptional; modern furnaces reach 95% AFUE, meaning higher long-term fuel costs
- 13 SEER rating is outdated by 2024 standards; newer systems achieve 16+ SEER2, saving significantly on cooling electricity
- No ENERGY STAR certification signals this system misses efficiency rebates and tax credits available in many states
- Single-stage compressor operates at full capacity whenever cooling is needed, less efficient than variable-capacity alternatives
Who Should Buy
Best For
Budget-focused homeowners replacing a failed system in moderate climates, or contractors equipping rental properties where tenant changes make premium efficiency less critical. This system delivers adequate comfort and reliability without premium pricing.
Consider Alternatives If
Homeowners in extreme climates seeking year-round comfort optimization, energy-conscious buyers targeting ENERGY STAR rebates, or anyone planning to stay 15+ years and recoup higher upfront costs through efficiency savings should explore higher-rated alternatives.
Installation
Installation complexity remains manageable for experienced technicians. The system requires metal exhaust flue for furnace venting and supports both upflow and downflow configurations for flexible ductwork integration. Electrical demands are modest, requiring 9.1 to 15 amps at 120V single-phase, standard for most residential panels. Line sets accept standard 3/8-inch liquid and 3/4-inch suction copper tubing with sweat connections.
Warranty & Reliability
Goodman provides a 10-year parts warranty conditional on online registration after purchase. This duration matches industry baseline but requires proactive registration, meaning failure to complete paperwork voids coverage. Coverage applies to component failures but excludes labor, refrigerant, and common wear items, so homeowners should budget separately for service calls.
