Review
Goodman's horizontal 3-ton system brings respectable efficiency to tight installation spaces. At 96% AFUE for heating and SEER16 for cooling, this unit targets contractors managing attic or crawlspace retrofits where vertical clearance is limited. The compact 21-inch height and horizontal configuration fit where traditional upflow units cannot. Goodman's reputation for straightforward service support and reasonable pricing makes this appealing to budget-conscious buyers who don't sacrifice efficiency.
The furnace delivers 80,000 BTU heating output with two-stage burner control and a variable-speed ECM blower reaching 1600 CFM maximum. Cooling capacity sits at 34,800 BTU through a single-stage scroll compressor using A-coil configuration. The 96% AFUE rating is excellent for gas furnaces, translating to measurable monthly utility savings. However, the single-stage condenser doesn't match the heating side's modulation capability, meaning the cooling system runs at full capacity until setpoint is reached rather than ramping gradually.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating costs by 10-15% versus standard 80% models
- Variable-speed ECM blower motor adjusts to actual demand, improving comfort and lowering electricity use
- Two-stage burner modulates heating output for better temperature control in mild weather
- PVC exhaust capability simplifies venting through modern plastic flue systems
- SEER16 cooling efficiency on the air conditioner side meets Energy Star standards
Cons
- 73.5 dB noise level is moderately loud, comparable to a dishwasher running
- R410A or R22 refrigerant compatibility creates uncertainty about future refrigerant availability and cost
- Single-stage condenser means cooling doesn't modulate like the heating side, running full power until temperature is reached
Who Should Buy
Best For
Contractors installing replacements in attic or horizontal spaces where a compact 21-inch height matters. Homeowners in moderate to cold climates who prioritize heating efficiency and can accept a 10-year warranty with online registration.
Consider Alternatives If
Anyone seeking ultra-quiet operation should look elsewhere, as 73.5 dB is on the noisier side for residential equipment.
Installation
Installation requires PVC or plastic exhaust venting, 208/230V single-phase power at 18.7 to 30 amps, and proper refrigerant lines with 3/4-inch suction insulation. The horizontal orientation demands level mounting in attics or crawlspaces. Included are 50 feet of liquid and suction lines, simplifying rough-in work. Most experienced HVAC technicians complete installation in four to six hours, though ductwork modifications may add time.
Warranty & Reliability
Goodman provides a 10-year parts warranty upon online registration, a solid commitment for residential equipment. This covers compressor, furnace heat exchanger, and coil components. Registration is straightforward but required to activate full coverage. The 10-year term positions this above budget brands but below premium manufacturers offering 12-year terms.
