Review
This Goodman 3-ton system represents a solid mid-market choice for homeowners balancing efficiency gains against installation costs. At $3,398, it sits above entry-level equipment but well below premium brands. The unit combines a high-efficiency gas furnace with a matching air conditioner in a single package, available in upflow or downflow configuration. Goodman holds strong brand recognition among contractors, backed by AHRI certification number 7368834 and a 10-year warranty with registration.
Performance numbers justify the price. The furnace delivers 80,000 BTU output with 96% AFUE efficiency using either natural gas or propane, paired with two-stage burner modulation for better part-load performance. The air conditioner side produces 35,000 BTU cooling with an 18 SEER2 rating and two-stage compressor. Variable-speed ECM blower runs at 1,200 CFM maximum but scales down during moderate weather, reducing energy consumption compared to single-speed motors. Operational noise measures 71 dBA, typical for this tonnage class.
Pros & Cons
Pros
- 96% AFUE furnace efficiency beats standard 80-90% models by 6-16 percentage points, saving hundreds annually on gas
- 18 SEER2 cooling rating qualifies as Energy Star certified, well above the 13 SEER minimum for 3-ton units
- Variable-speed ECM blower motor adjusts CFM from minimum to 1,200 max, reducing runtime and electricity waste
- Two-stage burner and two-stage compressor provide modulation for better part-load efficiency in mild weather
- Scroll compressor design proven reliable with lower vibration and noise at 71 dB, quieter than many 3-ton systems
Cons
- Product listing shows conflicting specs: title claims 17 SEER but specifications list 18 SEER2, creating confusion at purchase
- Only 10-year warranty requires online registration to activate, leaving unregistered units with shorter coverage
- R410A refrigerant compatibility noted but older R22 option limits future serviceability as R22 phases out
Who Should Buy
Best For
Homeowners in regions with balanced heating and cooling demands seeking to replace existing 3-ton systems will see real ROI from the 96% AFUE furnace. Contractors installing complete systems for new construction or major retrofits benefit from the AHRI certification and straightforward upflow configuration.
Consider Alternatives If
Budget-conscious buyers unwilling to spend $3,398 should look at standard 80 AFUE furnaces paired with 15 SEER coolers, which save $800-1,200 upfront despite higher long-term operating costs.
Installation
Installation requires standard HVAC skills and equipment. The unit measures 30 inches high by 17.5 inches wide by 21 inches deep, fitting most furnace closets and basement spaces. Electrical demands are modest at 115V single-phase 60Hz with breaker requirements between 21.3 and 35 amps. Refrigerant lines use 3/8-inch liquid and 7/8-inch suction connections with 50-foot maximum line length allowable. PVC exhaust flue compatibility simplifies venting compared to metal ductwork.
Warranty & Reliability
The 10-year parts warranty requires online registration to activate, a standard Goodman requirement that some buyers miss. Coverage includes the compressor and major components but does not cover labor or refrigerant. Unregistered units may receive shorter coverage periods. The evaporator coil carries separate warranty documentation. Always register immediately after installation to protect your investment.
