Review
The Goodman 3-ton gas furnace and air conditioner combination sits comfortably in the middle market, offering contractors and homeowners a proven, no-frills approach to HVAC replacement. This upflow A-coil system is manufactured through Online Supply and rated at 100,000 BTU heating capacity paired with 42,000 BTU cooling. With a 92% AFUE furnace rating and 14 SEER air conditioning efficiency, it delivers respectable performance without premium pricing, making it a practical choice for homes in moderate climates where efficiency gains beyond this tier don't justify the cost differential.
The system runs on R410A refrigerant with a scroll compressor and single-stage cooling cycle, producing a maximum 2,000 CFM airflow. The multi-speed blower motor allows technicians to tune performance for specific ductwork and comfort zones. Heating efficiency at 92% AFUE means roughly 92 cents of every heating dollar reaches conditioned space, which trails premium condensing furnaces but exceeds many older units significantly. For cooling, the 14 SEER rating provides solid performance without the noise and complexity of variable-displacement compressors.
Pros & Cons
Pros
- 92% AFUE furnace efficiency keeps heating costs reasonable with 100,000 BTU output
- 14 SEER cooling efficiency qualifies as good performance for mid-market equipment
- Multi-speed blower motor provides flexibility for comfort and noise control
- PVC/plastic exhaust flue compatibility simplifies installation in many homes
- 10-year warranty with online registration offers solid long-term protection
Cons
- Single-stage burner and compressor mean less modulation for efficiency gains
- 73 dB noise level is slightly louder than premium variable-stage competitors
- Not Energy Star rated, missing qualification for some rebate programs
Who Should Buy
Best For
Homeowners in moderate climates seeking a cost-effective replacement system with proven reliability. Contractors building spec homes or offering customer budgets around mid-market pricing will appreciate Goodman's straightforward installation and parts availability.
Consider Alternatives If
Anyone in cold climates requiring maximum heating efficiency or seeking Energy Star rebates should compare variable-speed alternatives first.
Installation
Installation requires 208/230 volt single-phase 60 Hz electrical service with a 22 to 35 amp breaker. The right-side flue location accepts PVC piping, simplifying exhaust routing in retrofit situations. At 21 by 21 by 30 inches and weighing 30 pounds, the compact footprint fits standard closets and utility spaces. The A-coil style connects directly to existing ductwork with 3/8-inch liquid and 7/8-inch suction lines, both requiring standard refrigeration fittings.
Warranty & Reliability
Goodman backs this system with a 10-year parts warranty when you complete online registration after installation. This covers compressor, heat exchanger, and most mechanical components, though labor and refrigerant are typically excluded. The 10-year term is competitive for mid-market equipment and provides meaningful protection against unexpected failures during the critical first decade of operation.
