Review
The Goodman 3-ton gas furnace and air conditioner system represents a straightforward, no-frills approach to residential climate control. This upflow configuration delivers 120,000 BTU of heating and 36,000 BTU of cooling capacity, fitting homes in the 1,200 to 1,500 square foot range. Goodman has built a reputation for practical engineering rather than premium features, and this model reflects that philosophy with proven reciprocating compressor technology and single-stage operation throughout.
The standout specification here is the 96% AFUE furnace efficiency, which ranks among the best available for gas furnaces. This translates directly to lower monthly heating bills, particularly valuable in climates where the furnace runs 5-7 months annually. The 13 SEER cooling rating meets current minimum standards but won't impress efficiency-focused buyers. The multi-speed blower motor adjusts airflow between 0 and 2,000 CFM, allowing the system to balance comfort and energy use across temperature swings.
Pros & Cons
Pros
- 96% AFUE furnace efficiency is top-tier for gas heating, reducing fuel costs noticeably
- 120,000 BTU heating capacity handles moderate climate zones effectively
- Multi-speed blower motor allows staged airflow control for comfort and efficiency
- PVC/plastic exhaust compatibility simplifies venting and reduces installation costs
- Single-stage reciprocating compressor is proven durable technology with straightforward servicing
Cons
- 13 SEER cooling rating is baseline for modern systems, not energy-efficient by today's standards
- Single-stage compressor and condenser mean no variable capacity for mild weather operation
- 74 dBA decibel level is moderately loud, noticeable in quiet residential settings
Who Should Buy
Best For
Homeowners in northern and central climates where heating demand exceeds cooling needs want this unit for its exceptional 96% AFUE rating. Budget-conscious contractors installing systems for cost-sensitive customers will appreciate the balance of reliable components and reasonable pricing.
Consider Alternatives If
Buyers prioritizing SEER2 cooling efficiency ratings of 16+ or seeking variable-capacity systems for all-season performance should explore higher-tier alternatives.
Installation
Installation favors experienced HVAC technicians. The upflow/downflow configuration works in basements and utility closets, while the right-side flue location offers flexibility in venting design. PVC/plastic exhaust piping simplifies flue runs and reduces materials cost. Electrical requirements are moderate at 208-230V single-phase 60Hz with a 19.1 to 30-amp breaker. Refrigerant lines use standard 3/8-inch and 7/8-inch connections with 3/8-inch insulation thickness on suction lines.
Warranty & Reliability
A 10-year parts warranty applies with online registration, covering the furnace heat exchanger and compressor. This is solid coverage for the price point, though registration is mandatory to activate it. Goodman's warranty support network is extensive, making claims straightforward in most markets. Extended warranties on evaporator coils are available separately.
