Review
The Goodman gas furnace and air conditioner system delivers reliable performance for residential applications at a competitive price point. This upflow A-coil configuration suits homes with basement mechanical rooms or downflow installations requiring horizontal orientation. Goodman's market reputation centers on practical engineering rather than luxury features, making this system a smart choice for budget-conscious homeowners and contractors who prioritize value and availability over cutting-edge technology.
Performance numbers justify the ENERGY STAR label. The furnace achieves 97% AFUE with modulating burners that scale output based on heating demand, delivering 80,000 BTU of heat while minimizing gas consumption. Cooling efficiency reaches SEER1 16, though the single-stage scroll compressor cannot modulate capacity for part-load efficiency during mild spring and fall conditions. The variable-speed ECM blower reaches 1600 CFM maximum airflow, adapting motor speed to maintain consistent comfort while reducing noise and energy draw.
Pros & Cons
Pros
- 97% AFUE furnace efficiency with modulating burner stages reduces gas waste and heating costs
- SEER1 16 air conditioning efficiency exceeds the 15 SEER rating listed in product title
- Variable-speed ECM blower motor optimizes airflow at 1600 CFM maximum, improving comfort and reducing noise
- Scroll compressor design proven for durability and quiet operation at 73 dB
- Plastic/PVC exhaust flue compatibility simplifies venting and reduces installation costs
Cons
- Single-stage condenser limits part-load efficiency during mild weather cooling cycles
- Specifications show 5 ton cooling capacity but product marketed as 3.5 ton, creating confusion about actual system size
- R410A or R22 refrigerant compatibility suggests older design; newer systems standardize on single refrigerant types
- 73 dB noise level ranks as moderately loud compared to high-efficiency variable-speed compressor systems
Who Should Buy
Best For
Homeowners in moderate climate zones who need to replace a failed HVAC system and want certified ENERGY STAR equipment with solid reliability. Contractors building affordable, efficient rental properties or spec homes will appreciate the straightforward installation and reasonable part availability through Online Supply.
Consider Alternatives If
Those in extreme climate zones needing maximum cooling capacity, noise-sensitive applications, or buyers seeking the absolute lowest operating costs should compare two-stage or variable-speed compressor systems instead.
Installation
Installation requires standard refrigerant line sizing with 3/8 inch liquid lines and 1 1/8 inch suction lines, both insulated at 1/2 inch thickness. Electrical connections use 115V single-phase 60 Hz power with breaker sizing between 23.5 and 40 amps. PVC exhaust venting simplifies gas furnace installation compared to older metal flue systems. Typical contractor installation time runs 4 to 6 hours for experienced technicians.
Warranty & Reliability
Goodman provides 10 years of parts and labor coverage when registered online after installation. This warranty ranks above industry standard 5-year coverage and protects against compressor failure, heat exchanger defects, and component failures. Registration is mandatory to activate the full 10-year term, so buyers should complete this step immediately upon system startup.
