Review
Goodman's 2-ton horizontal gas furnace and air conditioner system positions itself as an affordable efficiency upgrade for homeowners seeking high-efficiency heating and cooling in a space-constrained package. The combination of 96% AFUE and 18 SEER ratings places it in the premium efficiency tier without premium pricing, making it attractive for renovation projects, additions, or secondary systems. Built on proven scroll compressor and two-stage condenser architecture, this unit targets contractors and DIY-inclined homeowners who understand efficiency ratings and want measurable utility savings.
The furnace delivers 40,000 BTU on two burner stages, reaching 96% fuel utilization efficiency, meaning nearly every dollar of gas becomes usable heat. Cooling output of 23,000 BTU and 18 SEER efficiency translates to roughly 18 BTU of cooling per watt consumed, which exceeds Department of Energy minimum standards by 40%. The variable-speed ECM blower adjusts from 0 to 1200 CFM depending on demand, reducing runtime during shoulder seasons and cutting auxiliary electric consumption. Two-stage operation minimizes on-off cycling, extending compressor life and lowering peak noise during partial-load conditions.
Pros & Cons
Pros
- 96% AFUE furnace efficiency exceeds most competitors, reducing heating costs significantly over the system lifetime
- 18 SEER cooling efficiency qualifies for Energy Star and most utility rebates, saving 20-30% on AC costs versus 13 SEER units
- Two-stage compressor and condenser allow the system to run at partial capacity during mild weather, improving comfort and reducing short-cycling
- Variable-speed ECM blower motor adapts airflow from 0 to 1200 CFM, reducing standby power draw and noise
- PVC exhaust flue compatibility simplifies venting in retrofit applications where metal ductwork isn't feasible
- 10-year warranty with online registration provides solid coverage for parts and labor peace of mind
Cons
- 2-ton cooling capacity severely limits application to homes under 1000 square feet or as a secondary zone, not full-house replacement for most residences
- Horizontal configuration requires adequate plenum space above or to the side, making retrofit installation challenging in some homes
- 71 dB noise level runs louder than some competitors during full-stage operation, potentially noticeable in bedrooms or living areas
- Scroll compressor requires proper refrigerant charge and line sizing or premature failure risk increases
- R410A/R22 compatibility creates confusion, as R22 is being phased out and technicians may charge incorrectly if not verified upfront
Who Should Buy
Best For
This system fits homeowners with smaller homes, condos, or multi-zone setups who prioritize heating efficiency in cold climates. Contractors installing horizontal furnaces in tight attic or closet spaces will appreciate the compact 21 by 26 inch footprint and PVC venting flexibility.
Consider Alternatives If
Skip this if you need cooling capacity above 2 tons or have vertical ductwork only, as the horizontal design and limited tonnage won't meet whole-house demands for most families.
Installation
Horizontal installation requires adequate clearance above or beside ductwork, with 21 by 21.125 inch width fitting tighter spaces than vertical counterparts. PVC exhaust flue compatibility eliminates corrosion issues common with metal venting in high-efficiency applications. Electrical demand ranges from 15.3 to 25 amps at 208 or 230 volt, single-phase service, standard in most homes. Refrigerant line sizing must match 3/8 inch liquid and 3/4 inch suction valve specifications with 50-foot lineset included, critical for proper charge and performance.
Warranty & Reliability
Goodman provides a 10-year parts and labor warranty upon online registration, covering the compressor, heat exchanger, and refrigerant circuit. This warranty duration matches competitor offerings and includes evaporator coil protection. Registration is required, so retain documentation and activate coverage promptly to avoid claim denials. Coverage does not include refrigerant recharge, routine maintenance, or damage from improper installation.
