Review
This Goodman combination system represents a solid middle-ground option for homeowners seeking reliable heating and cooling without premium pricing. The horizontal configuration addresses a real installation challenge for contractors working in attics and tight crawlspaces where traditional upflow furnaces simply won't fit. Goodman's reputation for dependable equipment makes this particularly relevant for cost-conscious upgrades from failing dual systems.
Performance metrics tell a compelling efficiency story. The furnace delivers 97% AFUE with modulating burner stages that adjust flame height to match heating demand, resulting in quieter, more stable operation. The air conditioning side produces 29,000 BTU cooling capacity with a 16 SEER2 rating, far exceeding the federal minimum of 14 SEER2. The variable-speed ECM blower motor reaches 1,200 CFM maximum airflow while adapting to actual load requirements, avoiding the energy waste of constantly running at full capacity.
Pros & Cons
Pros
- 97% AFUE furnace efficiency means nearly all fuel converts to heat, reducing heating costs substantially
- 16 SEER2 rating significantly exceeds baseline requirements, qualifying for Energy Star certification and rebates
- Modulating burner stages provide precise temperature control and quieter operation than single-stage alternatives
- Variable-speed ECM blower motor adapts airflow to demand, improving comfort and reducing energy waste
- Compact horizontal A-coil design fits tight attics and crawlspaces where upflow units won't fit
- PVC exhaust capability simplifies venting in modern homes without masonry chimneys
Cons
- 71.5 dB noise level is moderately loud, noticeably audible in quiet spaces during operation
- Single-stage compressor cannot modulate cooling capacity, limiting part-load efficiency compared to variable-capacity models
- Spec discrepancy between title (2.5 tons) and actual unit (3 tons) creates confusion for sizing verification
Who Should Buy
Best For
Homeowners replacing aging furnace-only systems or mismatched AC units who need both heating and cooling efficiency in horizontal configurations. This system makes particular sense in colder climates where the 97% AFUE furnace justifies investment through reduced heating season costs.
Consider Alternatives If
Anyone seeking whisper-quiet operation or needing variable-capacity cooling for extreme climate variability should evaluate quieter, two-stage compressor alternatives.
Installation
Installation requires 115V single-phase 60Hz power with 17.1 to 25 amp breaker protection. The horizontal A-coil orientation demands careful ductwork planning to ensure proper refrigerant line slopes. Technicians will connect 3/8 inch liquid and 7/8 inch suction lines using the included 50-foot insulation kit. PVC exhaust venting simplifies installation in homes without traditional chimneys, though plastic vent termination still requires slope compliance for condensate drainage.
Warranty & Reliability
Goodman extends 10-year parts and labor coverage upon online registration, standard industry practice for residential systems at this price point. Coverage protects against compressor failure, heat exchanger cracks, and component defects. Registration is essential to activate coverage, so budget time for completing this step immediately after installation. This warranty duration provides meaningful protection during the equipment's peak usage years.
