Review
The Goodman 2.5-ton gas furnace and air conditioner system targets the mid-market HVAC buyer seeking balanced heating and cooling without premium pricing. This horizontal configuration operates at 97% AFUE on the heating side with modulating burners, positioning it squarely against Lennox and Carrier equivalents. Online Supply's offering includes full documentation, AHRI certification (7424271), and Energy Star qualification, signaling mainstream contractor acceptance.
Performance specs reveal a system optimized for moderate climates. The furnace delivers 80,000 BTU heating output with variable-speed ECM blower reaching 1600 CFM, while the cooling side produces 29,000 BTU at SEER 16, SEER1 efficiency. The scroll compressor uses R410A refrigerant in a single-stage configuration. Electrical requirements are modest: 115V single-phase 60Hz with 17.1 to 25-amp breaker sizing, making integration into existing home panels straightforward for most installations.
Pros & Cons
Pros
- 97% AFUE with modulating burners saves 10-15% annually on natural gas compared to single-stage furnaces in typical use
- SEER 16 cooling efficiency exceeds most competitor offerings in the 2.5-ton class by 2-3 SEER points
- Variable-speed ECM blower motor with 1600 CFM maximum adapts to load, reducing runtime noise and energy consumption
- Energy Star certified with rebate eligibility through many utility providers, offsetting initial system cost
- PVC flue compatibility simplifies installation in retrofit applications where metal venting is unavailable
Cons
- 3.5-ton condenser paired with 2.5-ton furnace creates potential capacity mismatch, requiring careful HVAC design
- Single-stage compressor on the condenser limits part-load efficiency compared to two-stage alternatives
- 71.5 dBA noise level is moderate-to-loud for single-stage operation, noticeable in quiet residential settings
Who Should Buy
Best For
Homeowners in moderate climates (zones 4-7) replacing older furnaces who want lower heating bills without oversizing. Contractors valuing straightforward installations in homes with tight basement spaces or attics where the horizontal configuration fits better than vertical units.
Consider Alternatives If
Buyers in cold climates needing consistent 2.5-ton cooling capacity should avoid this unit due to the compressor-furnace tonnage mismatch, and anyone prioritizing whisper-quiet operation will find the 71.5 dBA unacceptable.
Installation
The horizontal A-coil design suits attics and crawlspaces with limited headroom, measuring 34.5 inches tall and 50 feet in suction line length. PVC flue compatibility eliminates metal venting costs. Refrigerant lines are 3/8 inch liquid and 7/8 inch suction with 3/4 inch insulation included. Variable-speed blower wiring is standard for modern thermostats. Downflow/horizontal configuration requires proper return air plenum design for optimal CFM delivery.
Warranty & Reliability
Goodman backs this system with a 10-year compressor and parts warranty upon online registration, typical for branded equipment at this price point. Coverage includes labor in most cases during the first year through authorized dealers. This warranty mirrors competitors like Carrier Comfort and Lennox systems, offering adequate protection for homeowners planning 15-plus year equipment lifecycles.
