Review
The Goodman 3-ton upflow system occupies a practical middle ground in the residential HVAC market. At $647, this matched unit combines an 80,000 BTU furnace with a 34,800 BTU air conditioner, positioned squarely for mid-range applications where budget matters as much as performance. Online Supply's offering targets contractors managing multiple installations and homeowners replacing aging equipment without financial flexibility for premium systems.
Real-world performance centers on these numbers: 80% AFUE with two-stage burners, 14 SEER cooling, and a high-efficiency multi-speed blower reaching 2000 CFM. The system uses R410A refrigerant with standard 3/8-inch liquid and 7/8-inch suction lines, sized for straightforward installations. Energy Star certification and a 16 SEER1 rating confirm the cooling efficiency claim. The scroll compressor handles single-stage operation, meaning less cycling efficiency during partial-load conditions.
Pros & Cons
Pros
- Exceptional value at $647 for a matched 3-ton gas furnace and air conditioning system
- 80% AFUE with two-stage burners delivers consistent, efficient heating across variable weather
- High-efficiency multi-speed blower motor maxes out at 2000 CFM for better air distribution
- 34,800 BTU cooling capacity with 14 SEER rating handles summer loads effectively
- Energy Star certified with 16 SEER1 rating shows solid efficiency credentials
- 10-year warranty with online registration provides reasonable coverage at this price tier
Cons
- 80% AFUE is acceptable but trails high-efficiency furnaces rated 90-95% AFUE
- Single-stage condenser means less modulation during mild cooling days, slightly higher operating costs
- 73.5 dB noise level is moderately loud, noticeable in quieter installations
Who Should Buy
Best For
Contractors installing budget-conscious residential systems and homeowners replacing older equipment in 1200-1400 square foot homes. This system makes sense when you need reliable heating and cooling without premium efficiency pricing.
Consider Alternatives If
Buyers in high-efficiency mandate areas or those seeking premium SEER2 ratings should explore 95% AFUE furnaces and variable-speed cooling systems instead.
Installation
This upflow A-coil configuration measures 38.25 inches tall by 29 inches wide and deep, fitting standard utility closets or basements. The system requires 208/230V single-phase power with a minimum 18.7 amp breaker and maximum 30 amp capacity. Metal exhaust flue is mandatory, and the 50-foot suction line with 3/4-inch insulation comes pre-included, simplifying field preparation.
Warranty & Reliability
The 10-year warranty requires online registration but delivers meaningful coverage for parts and labor during the critical ownership window. At this price point, a decade of protection represents solid value, though homeowners should complete registration immediately upon purchase to lock in coverage.
