Review
This Goodman system enters a crowded mid-range HVAC market with respectable efficiency numbers at an entry-level price. The 3-ton configuration suits single-story homes and smaller multi-level properties, while the horizontal design appeals to installers working in constrained attics and crawlspaces. Two-stage heating and cooling reflect modern equipment standards, moving beyond the on-off cycling that wastes energy in older systems. The 96% AFUE and 18 SEER1 ratings position it as a legitimate energy-saving upgrade, not a budget-basement compromise.
The furnace delivers 100,000 BTU heating across two burner stages, with the variable-speed ECM blower reaching 2,000 CFM maximum. The air conditioning side provides 35,000 BTU cooling through a two-stage scroll compressor operating on R410A or R22 refrigerant. The 18 SEER1 rating indicates good part-load efficiency, meaning the system avoids the wasteful full-blast operation common in single-stage units. At 71 dB, noise levels stay below most residential complaints. Suction lines accept 3/4-inch insulation, meeting modern installation standards for refrigerant temperature maintenance.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating fuel consumption and lowers winter utility bills noticeably
- 18 SEER1 and two-stage cooling compressor handle variable load conditions without constant cycling
- Variable-speed ECM blower motor automatically adjusts to room demand, improving comfort and reducing electricity use
- Scroll compressor design is quieter at 71 dB and more reliable than reciprocating alternatives
- PVC exhaust compatibility simplifies installation in tight attics without metal ductwork requirements
- 10-year warranty with online registration provides solid coverage for major components
Cons
- Spec sheet lists both 3-ton and 5-ton ratings, creating confusion about actual capacity and matched coil requirements
- Cooling capacity shows 35,000 BTU, which underperforms typical 3-ton systems (36,000 BTU) and may require oversizing
- Requires 21.3-35 amp breaker, limiting installation to homes with available electrical capacity
Who Should Buy
Best For
Homeowners in mixed climates with existing gas furnaces who need combined heating and cooling efficiency without premium pricing. DIY-handy contractors will appreciate the horizontal configuration and straightforward PVC exhaust installation for attic or crawlspace placement.
Consider Alternatives If
Anyone needing pure 3-ton cooling capacity or operating in regions where SEER2 ratings (not SEER1) are the efficiency standard should verify compatibility with existing ductwork and coil matching before purchasing.
Installation
Horizontal configuration mounts flat in attics without requiring vertical clearance. PVC exhaust simplifies venting through exterior walls or roofs, eliminating expensive metal ductwork. The system draws 115V single-phase power with breaker requirements between 21.3 and 35 amps, requiring dedicated circuits in older homes. Line sets ship pre-insulated up to 50 feet, covering most residential installations without field wrapping. Sweat-type valve connections demand basic soldering skills or professional help.
Warranty & Reliability
Goodman provides 10 years of parts coverage upon online registration, standard industry practice for this equipment tier. Warranty excludes labor and damage from improper installation, so homeowners should ensure professional setup. The warranty transfers to second owners on the same property, beneficial if you sell within the coverage period.
