Review
Goodman's horizontal furnace-AC combo arrives as a practical solution for homeowners tired of multi-thousand-dollar system costs. Priced at $89, this 3-ton unit targets contractors managing replacement projects and budget-conscious buyers willing to trade premium positioning for proven baseline performance. The horizontal configuration suits modern homes with limited mechanical space, and the two-stage heating and cooling design suggests Goodman engineered for real-world comfort rather than marketing hype.
Performance numbers tell the substantive story here. The furnace delivers 40,000 BTU of heating with 96% AFUE efficiency, which translates to measurable savings on gas bills. The air conditioning side produces 35,000 BTU cooling capacity with an impressive 18 SEER1 rating (exceeding the claimed 16 SEER specification). The variable-speed ECM blower maxes out at 1,200 CFM and modulates based on demand, avoiding the energy waste of fixed-speed motors. Refrigerant type is R410A, and the scroll compressor handles two-stage operation effectively.
Pros & Cons
Pros
- 96% AFUE furnace efficiency keeps heating costs low, translating to $100-150 annual savings versus 90% units
- 18 SEER1 cooling rating beats the stated 16 SEER specification by a meaningful margin
- Variable-speed ECM blower motor reduces electricity draw during part-load operation
- Two-stage burner and two-stage condenser allow modulating operation for comfort and efficiency
- Compact horizontal design (21 x 21.125 x 26 inches) fits tight spaces like attics or crawlspaces
- PVC exhaust requirement simplifies venting in homes without masonry chimneys
Cons
- No AHRI certification documentation readily available for pairing with matching coils in field
- 40,000 BTU heating output may leave 4-ton homes slightly underspec in cold climates below minus-10 degrees
- 71 dB noise level is higher than premium variable-speed units, noticeable during full-stage operation
Who Should Buy
Best For
Contractors replacing older 3-ton systems in moderate climates and homeowners upgrading from 90% AFUE equipment who value immediate cost savings. Also ideal for rental properties or secondary residences where premium warranty and extended support justify less investment.
Consider Alternatives If
Homeowners in extreme cold climates needing maximum heating capacity, or those prioritizing near-silent operation should consider higher-tonnage or premium brands.
Installation
Horizontal installation suits attics, crawlspaces, and utility closets where vertical clearance is limited. The unit requires 208/230V single-phase 60 Hz electrical service and breaker sizing between 21.3 and 35 amps. PVC or plastic venting simplifies exhaust routing and eliminates costly chimney modifications. Suction and liquid line sizes are 7/8-inch and 3/8-inch respectively, with 3/4-inch insulation thickness on the suction line to prevent condensation.
Warranty & Reliability
The 10-year parts warranty activates upon online registration and covers manufacturing defects. This is respectable mid-tier coverage, not industry-leading but substantially better than budget-basement units. Registration is straightforward and critical for claim eligibility. Extended coverage options are not mentioned in available documentation.
