Review
Goodman's combined gas furnace and air conditioner system targets cost-conscious homeowners and contractors seeking reliable performance without premium pricing. The 40,000 BTU furnace pairs with a 23,600 BTU cooling unit, making this appropriate for smaller residential spaces. With ENERGY STAR certification and rebate eligibility, the system appeals to buyers focused on efficiency gains and payback periods. The downflow configuration distinguishes this from typical residential units, offering flexibility in equipment placement.
The 96% AFUE furnace rating represents strong heating efficiency, delivering nearly all fuel energy as usable heat while minimizing waste. On the cooling side, the 16 SEER2 condenser with scroll compressor provides legitimate efficiency and quiet operation at 71.5 decibels. The two-stage burner and variable-speed ECM blower enable better modulation than single-stage alternatives, improving comfort during partial-load operation. However, the actual 23,600 BTU cooling output matters more than SEER rating alone when sizing for your home, requiring precise load calculations.
Pros & Cons
Pros
- 96% AFUE furnace efficiency exceeds minimum federal standards by 8 percentage points, reducing heating costs measurably
- 16 SEER2 condenser rating qualifies as ENERGY STAR, eligible for utility rebates in most regions
- Two-stage burner and variable-speed ECM blower motor provide comfort and efficiency gains over single-stage units
- Scroll compressor design is known for durability and quiet operation at 71.5 dB
- Downflow configuration suits retrofits and compact spaces where traditional upflow units won't fit
- PVC exhaust flue requirement makes installation simpler and cheaper than metal vent systems
Cons
- SKU mismatch creates confusion, the unit is badged as 2 Ton but specs list 3 Ton capacity
- Single-stage condenser means no variable cooling, less sophisticated than two-stage or inverter units
- 23,600 BTU actual cooling output falls short of typical 2-ton systems, making sizing critical for proper performance
- Limited technical support available through Online Supply compared to direct Goodman channels
Who Should Buy
Best For
This system suits homeowners in mild to moderate climates replacing 15-year-old equipment who prioritize upfront cost and steady performance. Contractors installing new construction or retrofits in space-constrained applications will appreciate the downflow configuration and straightforward installation requirements.
Consider Alternatives If
Skip this if you live in extreme climates, need premium variable-capacity cooling, or require direct manufacturer support, as resellers like Online Supply offer limited technical resources.
Installation
Installation requires standard 115V, single-phase 60Hz power with 12.4 to 20 amp breaker capacity, easily accommodated in most homes. PVC exhaust venting simplifies installation compared to metal flue systems, cutting labor time and material costs. Refrigerant lines need proper insulation, suction line diameter is 3/4 inch and liquid line is 3/8 inch. Downflow orientation suits basements, closets, or attics where horizontal ducting runs are feasible.
Warranty & Reliability
Goodman provides 10 years of parts and labor coverage upon online registration, a standard offering in this price tier. The warranty covers compressor, scroll pump, and coil defects but excludes improper installation or refrigerant handling issues. Online Supply handles warranty claims, so response times may differ from direct manufacturer service. Registration is mandatory, not automatic, so homeowners must complete the process shortly after installation.
