Review
This Goodman system pairs a 120,000 BTU gas furnace with a 42,000 BTU air conditioner in a downflow configuration, covering standard residential cooling and heating across most climate zones. The 3.5-ton cooling capacity and 96% AFUE heating efficiency position it as a practical middle option, balancing meaningful performance improvements against budget constraints. At $3,136, it undercuts premium brands while meeting modern efficiency standards, making it popular for straightforward replacement scenarios where homeowners want measurable utility bill reductions.
The furnace delivers 96% AFUE efficiency through two-stage burner technology that modulates heating output based on demand, reducing short-cycling and energy waste. The air conditioning side achieves 14 SEER1 rating using a scroll compressor and R410A refrigerant, though single-stage operation means it runs at full capacity rather than scaling down on mild days. Variable-speed ECM blower motor in the furnace adjusts airflow dynamically, improving comfort consistency and extracting more usable heat from combustion. These specifications translate to approximately 12-15% heating efficiency gains over 80% AFUE units.
Pros & Cons
Pros
- 96% AFUE furnace converts nearly all fuel to heat, reducing heating bills by 10-15% versus 80% AFUE systems
- 14 SEER cooling matches mid-range AC standards, Energy Star certified for tax incentive eligibility
- Two-stage burner and variable-speed ECM blower motor optimize comfort and efficiency across load conditions
- 120,000 BTU heating output handles most residential applications, including 3-4 bedroom homes in cold climates
- PVC/plastic exhaust compatibility simplifies venting in retrofit situations where metal flue isn't practical
Cons
- Single-stage compressor in AC unit means less part-load efficiency compared to dual-stage competitors in the $4,000+ range
- 73 dB noise level is audible during operation, slightly louder than premium models with sound dampening
- 5-ton condenser paired with 3.5-ton furnace creates minor tonnage mismatch that reduces optimal performance
Who Should Buy
Best For
Homeowners replacing complete HVAC systems in homes under 3,500 sq ft who prioritize affordability without sacrificing meaningful efficiency upgrades. Contractors seeking reliable mid-market equipment for residential replacement jobs where customers want utility savings without high-end pricing.
Consider Alternatives If
Anyone needing ultra-quiet operation or seeking premium efficiency should explore dual-stage or inverter-driven systems in higher price brackets.
Installation
Downflow configuration routes air downward, suitable for basements or ground-level installations with return plenums below. System requires 115V single-phase power with 22-35 amp breaker sizing, standard household electrical service in most homes. Suction line needs 3/8-inch insulation over its 7/8-inch diameter, and PVC flue compatibility simplifies venting work. Proper commissioning requires checking refrigerant charge and airflow calibration, typically 4-6 hours for experienced technicians.
Warranty & Reliability
10-year parts warranty with online registration covers component failures, though registration is mandatory to activate full coverage. This matches industry standards for equipment in this price tier. Goodman's warranty reputation remains solid, though some contractors report occasional claim processing delays. Coverage excludes wear items and installation labor.
