Review
Goodman's 3 Ton horizontal system represents a practical middle ground in the split AC and furnace market. Priced at $2,142, it targets homeowners wanting measurable efficiency gains over legacy equipment without the premium associated with ultra-high SEER ratings. The combination of a 17 SEER cooler, two-stage components, and Energy Star certification signals genuine performance improvements, though the 80% AFUE furnace reveals this unit's real positioning, value tier rather than premium efficiency class.
Performance specs tell a focused story. The air conditioner delivers 35,000 BTU cooling capacity with a two-stage scroll compressor running at 71 dBA, quiet enough for most residential settings. The furnace produces 80,000 BTU heating output across two burner stages, letting the system modulate rather than cycling on and off constantly. Variable speed blower technology reaches 2000 CFM maximum, and the unit runs on either R410A or R22 refrigerant. These details indicate competent mid-tier engineering rather than leading-edge innovation.
Pros & Cons
Pros
- 17 SEER1 rating beats the stated 17 SEER marketing claim, with Energy Star certification confirming efficiency
- Two-stage condenser and two-stage furnace burner reduce cycling losses and improve comfort consistency
- 80,000 BTU heating output with 80% AFUE handles most residential heating demands adequately
- Variable speed blower motor adjusts CFM from low to 2000 maximum, reducing energy waste during partial load operation
- Scroll compressor technology provides quieter operation at 71 dBA and improved reliability compared to reciprocating designs
Cons
- 80% AFUE furnace efficiency is outdated by today's standards, when 95% AFUE units are increasingly common and often comparable in cost
- Horizontal configuration limits placement options, restricting attic installations for many homeowners
- Dual refrigerant compatibility (R410A or R22) creates potential confusion during service and adds technician qualification variables
Who Should Buy
Best For
Homeowners upgrading from 13-14 SEER systems who want measurable efficiency improvements without the premium cost of 20+ SEER units. Those with existing horizontal ductwork or attic constraints where this configuration makes sense will see the best value.
Consider Alternatives If
Anyone seeking cutting-edge efficiency or planning to stay in their home 15+ years should explore 95% AFUE furnaces paired with 18-20 SEER coolers instead.
Installation
Horizontal configuration requires specific placement, typically in attics or crawlspaces with low vertical clearance. The unit measures 21 inches tall, 21.125 inches wide, and 26 inches deep, with a 50-foot maximum suction line run. Valve sizing is straightforward with 3/8-inch liquid and 7/8-inch suction lines, plus 3/4-inch insulation thickness. Technicians should verify metal flue exhaust requirements and electrical capacity of 21.3 to 35 amps at 120V, 1-phase, 60Hz.
Warranty & Reliability
The 10-year warranty requires online registration with Goodman and covers manufacturing defects comprehensively. This duration matches industry standard for sealed components but trails premium competitors offering 10-year parts plus extended labor coverage. The Evaporator Coil Warranty provides additional protection. Registration is straightforward but mandatory, so document serial numbers immediately upon installation.
