Review
The Goodman 3-ton gas furnace and air conditioner system represents a practical middle-ground solution for homeowners balancing efficiency needs with upfront costs. This upflow A-coil configuration combines an 80,000 BTU furnace with a 36,000 BTU (3-ton) air conditioner, making it suitable for homes in moderate climates where heating and cooling demands are reasonably balanced. Goodman's reputation for straightforward, serviceable equipment positions this unit as a contractor favorite.
The furnace delivers impressive 96% AFUE efficiency, meaning 96 cents of every heating dollar translates to home warmth rather than exhaust loss. Cooling efficiency at 13 SEER is adequate but not advanced, standard for single-stage reciprocating compressor designs. The multi-speed blower motor adjusts airflow across a 2000 CFM maximum range, optimizing comfort during partial-load conditions. Electrical requirements are modest at 115V single-phase 60 Hz with 19.1 to 30 amp breaker sizing, fitting most existing home electrical panels.
Pros & Cons
Pros
- Exceptional 96% AFUE furnace efficiency reduces heating costs significantly in winter months
- Flexible refrigerant compatibility with R410A or R22 eases installation and future servicing
- Single-stage reciprocating compressor is proven technology with strong track records for durability
- Multi-speed blower motor optimizes comfort and reduces energy waste during partial-load operation
- PVC exhaust flue option simplifies installation in tight spaces compared to metal ductwork
Cons
- 13 SEER cooling efficiency is baseline for today's market, not premium performance
- Single-stage cooling compressor cannot modulate capacity, cycling on and off rather than ramping
- Not Energy Star certified, missing qualification for some rebate programs
- 74 dB noise level is moderately loud for outdoor unit installations near living areas
Who Should Buy
Best For
Homeowners in temperate regions where heating loads dominate the HVAC year should strongly consider this system. Budget-conscious buyers who prioritize furnace efficiency and heating performance over advanced cooling features will find excellent value here.
Consider Alternatives If
Customers in hot climates requiring extended cooling seasons should explore higher SEER options, and those chasing Energy Star rebates will need to look at certified alternatives.
Installation
Installation is straightforward for experienced HVAC technicians. The upflow/horizontal design suits attic, basement, or closet placement with 34.5-inch height and 21 by 28.75-inch footprint. Sweat valve connections use standard 3/8-inch liquid and 7/8-inch suction lines with 3/8-inch insulation thickness. PVC exhaust venting simplifies flue routing compared to metal alternatives, with the flue exit positioned on the right side.
Warranty & Reliability
The 10-year parts and labor warranty requires online registration at purchase but provides substantial protection against premature failure. This coverage is competitive within Goodman's product line and covers internal components including the compressor, heat exchanger, and control board. Registration typically takes minutes and unlocks coverage; failure to register reduces protection to base warranty periods.
