Review
This 2.5-ton Goodman combination system pairs gas heating with air conditioning in a single horizontal unit designed for attic and tight mechanical spaces. Online Supply positions this as a practical replacement option for contractors managing mid-range residential HVAC upgrades. The horizontal configuration with 21-inch height, 21.125-inch width, and 26-inch depth fits standard attic drops where vertical clearance matters. Single-stage operation keeps complexity and cost down, appealing to budget-conscious installations across residential markets.
The furnace delivers 100,000 BTU heating output at 92% AFUE, meaning 92 cents of every gas dollar converts to usable heat. Cooling production hits 30,000 BTU with 14 SEER efficiency, suitable for moderate climate zones where high-tonnage cooling isn't essential. The multi-speed blower motor reaches 2000 CFM maximum airflow, supporting reasonable comfort modulation across varying outdoor temperatures. However, single-stage burner and condenser operation means the system runs at full capacity or off, missing the efficiency gains variable systems achieve during partial-load conditions.
Pros & Cons
Pros
- 92% AFUE gas furnace exceeds minimum standards and reduces heating costs by 8-12% versus 80% AFUE models
- 14 SEER air conditioning handles 30,000 BTU cooling with solid single-stage efficiency for moderate climates
- 100,000 BTU heating capacity covers typical residential needs with single-stage burner simplicity
- Horizontal configuration with 21-inch height fits standard attic drops and tight mechanical spaces
- Multi-speed blower motor at 2000 CFM maximum allows better airflow control and comfort tuning
- PVC/plastic exhaust flue compatibility simplifies installation in homes without masonry chimneys
Cons
- Not Energy Star certified, missing 15-20% efficiency gains available in premium models
- Single-stage cooling and heating limits modulation, reducing efficiency in mild weather conditions
- 72 dB noise level runs 3-5 dB louder than variable-speed competitors during operation
- Tonnage mismatch issue: specs list both 2.5 ton and 3.5 ton, creating confusion for contractors
- Refrigerant compatibility with both R410A and R22 suggests this may be older stock or legacy equipment
Who Should Buy
Best For
Contractors building rental properties or budget-conscious homeowners replacing aging systems in moderate climates where 14 SEER cooling and 92% AFUE heating deliver acceptable performance. This unit works especially well for horizontal attic installations where space is limited and standard ductwork already exists.
Consider Alternatives If
Anyone in hot climates wanting maximum cooling efficiency, homeowners seeking Energy Star certification for utility rebates, or installations requiring variable-capacity compressors for superior comfort and efficiency.
Installation
Installation requires 208/230 volt single-phase 60 Hz electrical service with breaker sizing between 17.1 and 25 amps, standard for most residential panels. The PVC/plastic exhaust flue requirement simplifies venting compared to masonry-only alternatives. Refrigerant lines use 3/8-inch liquid and 3/4-inch suction sizing with 3/4-inch insulation thickness on the suction line, requiring 50 feet maximum line length. Horizontal configuration means ductwork connects above the unit without complex framing modifications.
Warranty & Reliability
Goodman provides a 10-year parts warranty when registered online, covering compressor, heat exchanger, and coil components. This matches industry midrange standards but trails premium brands offering 10-15 years on compressors. Registration is essential, as coverage drops significantly without it. Warranty duration is reasonable for budget equipment but doesn't include labor, leaving service calls out-of-pocket after year one.
