Review
Goodman has built a solid reputation as a value-focused HVAC manufacturer, and this upflow split system exemplifies that approach. The 3-ton cooling and 80,000 BTU heating capacity handles most single-story homes and smaller two-story properties. At $89 for the condenser unit alone, you're looking at genuine affordability, though the furnace, installation labor, and ductwork will add substantially to the final bill. This system carries AHRI certification number 7424266 and Energy Star qualification, signals of legitimate equipment sizing and efficiency.
The efficiency numbers tell a compelling story. The 16 SEER cooling rating places this unit well above baseline 13 SEER equipment, translating to approximately 23% better cooling efficiency. The 97% AFUE furnace rating means you lose only 3% of heating energy up the flue, compared to 15-20% loss in older systems. Real-world annual savings typically reach $300-600 depending on local energy rates and climate. The two-stage compressor and modulating burner work together to minimize on-off cycling, reducing stress on components and extending equipment lifespan.
Pros & Cons
Pros
- 16 SEER rating qualifies for Energy Star certification, reducing cooling costs by 20-30% versus 13 SEER units
- 97% AFUE heating efficiency means minimal wasted fuel during winter months, saving $200-400 annually on gas
- Two-stage compressor and modulating gas burner adapt to load conditions, reducing runtime and wear
- Variable-speed ECM blower motor maximizes comfort and efficiency throughout the heating and cooling season
- 10-year warranty with online registration provides substantial coverage at this price point
Cons
- 70.4 dB noise level runs louder than premium units, which may matter in quiet neighborhoods or near bedrooms
- Product listing shows conflicting tonnage specs (3 ton title versus 5 ton in specifications), creating confusion
- Requires licensed technician installation due to gas connections, adding $800-1,500 to total system cost
Who Should Buy
Best For
Homeowners in moderate climates who need a reliable furnace-AC combo and can afford professional installation. This system suits those upgrading 15+ year old equipment where energy savings will justify the investment within 5-7 years.
Consider Alternatives If
Budget-constrained buyers unable to afford professional installation, or those in consistently mild climates where cooling needs are minimal and SEER ratings offer little payback.
Installation
Professional installation is mandatory for this gas furnace system. You'll need a licensed technician to handle refrigerant charge, gas line connections, ductwork modifications, and venting setup. The unit requires 115V single-phase power with breaker capacity between 21.8 and 35 amps, which most homes already provide. Upflow configuration makes it suitable for basements or utility closets. Installation typically requires 6-10 hours and costs $800-1,500 in most markets.
Warranty & Reliability
Goodman offers 10 years of parts coverage when you register online, a meaningful protection period at this price level. This covers compressor failures, heat exchanger cracks, and component defects. Labor is not included, so repairs beyond warranty expiration become your responsibility. Registration must happen within 30 days of installation to activate full coverage.
