Review
Goodman's 4-ton/5-ton gas furnace and air conditioner system represents a solid mid-market choice for contractors and homeowners replacing aging equipment. This downflow configuration suits homes with basement or crawlspace installations where space constraints matter. At $3,136, it positions itself as an affordable entry into high-efficiency cooling and heating without premium pricing. The combination of 96% AFUE heating and 16 SEER cooling places it squarely in today's efficiency expectations for ENERGY STAR certification.
Performance data shows this system delivers 120,000 BTU heating output with two-stage burner control for responsive comfort and efficiency. The 45,500 BTU cooling capacity pairs with a 16 SEER rating, translating to measurable summer utility savings. Variable-speed ECM blower technology adjusts airflow to 2000 CFM maximum, adapting to heating and cooling demands. Scroll compressor design and 115V single-phase electrical requirements keep installation straightforward for most contractors working with standard residential panels.
Pros & Cons
Pros
- 96% AFUE furnace with two-stage burners minimizes energy waste during heating cycles
- 16 SEER cooling efficiency exceeds baseline standards, reducing summer electricity costs
- Variable-speed ECM blower motor adjusts CFM up to 2000 for better comfort and efficiency
- Supports both natural gas and propane fuel, offering flexibility for different installations
- 10-year warranty with online registration provides solid coverage against defects
- ENERGY STAR certified, qualifying buyers for utility rebates in many regions
- Scroll compressor design is proven reliable with lower maintenance requirements
Cons
- Single-stage cooling compressor cannot modulate capacity, reducing efficiency during light loads
- 73 dB noise level runs slightly louder than premium variable-capacity units
- Specification discrepancy lists both 4-ton and 5-ton tonnage, creating uncertainty about actual capacity
- Plastic PVC exhaust requirement limits installation flexibility in some older homes
- R410A/R22 refrigerant compatibility may complicate future repairs as R22 phases out
Who Should Buy
Best For
Contractors installing complete HVAC systems in new construction or full replacements where downflow configuration fits the home's layout. Homeowners in moderate climates seeking reliable, efficient dual-fuel systems at competitive pricing without premium variable-capacity features.
Consider Alternatives If
Anyone needing variable-capacity cooling for extreme climate zones, or homeowners prioritizing whisper-quiet operation should consider higher-end models with modulating compressors.
Installation
Downflow installation suits basements, attics, and closets where horizontal or vertical orientation works. The unit requires plastic PVC exhaust venting, a significant advantage over metal flue systems in corrosive environments. Electrical connections use standard 115V single-phase 60Hz power with breaker sizing between 23.9 and 40 amps. Refrigerant line insulation comes pre-applied at 1/2 inch thickness, simplifying on-site preparation. Most experienced installers can complete this system in one day.
Warranty & Reliability
Goodman provides a standard 10-year parts warranty upon online registration, protecting against manufacturing defects in compressor, coils, and controls. This coverage is industry-standard for mid-range equipment, offering reasonable peace of mind without extended service agreements. Registration is straightforward and strongly recommended to activate full warranty protection.
