Review
The Goodman 3-ton gas furnace and air conditioner combination addresses a common contractor need: reliable dual-fuel heating and cooling in one system. Listed as 3 tons for cooling but specified as 5 tons in product data, this unit carries a 96% AFUE gas furnace paired with a 16 SEER1 air conditioning section. Goodman's reputation for straightforward manufacturing and parts availability makes this an attractive option for both new installations and retrofits where upflow orientation works with existing ductwork.
Performance metrics tell the efficiency story. The furnace delivers 100,000 BTU heating with two-stage burners, while the air conditioner produces 34,800 BTU cooling at the stated 3-ton capacity. The ECM multi-speed blower accommodates up to 1,600 CFM and adjusts automatically to match load demands, reducing energy waste during light cooling or heating cycles. At 73.5 dB under full load, noise remains acceptable for basement or mechanical room placement. Energy Star certification confirms compliance with EPA efficiency standards.
Pros & Cons
Pros
- 96% AFUE furnace efficiency translates to roughly $100-150 annual savings versus 80% models in heating-heavy climates
- 16 SEER1 cooling rating and Energy Star certification deliver measurable summer efficiency gains
- Two-stage burner and ECM multi-speed blower reduce short cycling and minimize comfort swings
- Scroll compressor handles R410A or R22 refrigerant, offering retrofit flexibility for existing systems
- PVC plastic flue compatibility simplifies venting compared to metal duct requirements
Cons
- 5-ton rating mismatch with stated 3-ton capacity creates specification confusion that buyers must verify before purchase
- 73.5 dB noise level at full capacity may be noticeable in quieter homes, though typical operation runs lower
- Single-stage condenser lacks variable-speed efficiency optimization during partial-load conditions
Who Should Buy
Best For
Contractors and homeowners in cold-weather regions where furnace efficiency drives utility bills, or those replacing older 80-85% AFUE systems. This unit works best in upflow configurations in basements or crawlspaces where the 30-inch height fits existing clearances.
Consider Alternatives If
Buyers in mild climates where furnace efficiency gains are minimal, or anyone needing downflow-only installation without reconfiguration options.
Installation
Upflow configuration requires vertical ductwork above the unit, standard in basements and crawlspaces. The 30-inch height, 21-inch width, and 21-inch depth fit typical mechanical closets. Plastic PVC flue venting simplifies exterior exhaust routing compared to metal vent systems. Electrical needs include 115V, single-phase 60 Hz service with 18.7-30 amp breaker sizing. A qualified HVAC installer should handle refrigerant lines, evaporator coil integration, and gas line connections.
Warranty & Reliability
Goodman provides a 10-year parts and labor warranty with online registration, standard industry coverage for combination systems. This protects against compressor failure, heat exchanger defects, and component malfunctions during the critical first decade. Registration is mandatory, so save your receipt and complete it within 30 days of installation to activate full coverage.
