Review
This Goodman combo system represents a practical middle ground for contractors and homeowners balancing heating and cooling needs. The unit combines an 80,000 BTU furnace with a 42,000 BTU air conditioning condenser, designed for downflow installation where ductwork runs beneath the equipment. At 3.5 tons of cooling capacity and 96% AFUE efficiency, it positions itself as a solid performer for moderate climates without premium pricing.
The heating side impresses with 96% AFUE, meaning you lose only 4% of fuel energy up the flue, compared to 89-91% on older equipment. Cooling delivers 14 SEER through a single-stage scroll compressor, a reliable design that sacrifices modulation for simplicity. The multi-speed blower motor running at up to 1600 CFM provides flexibility, though the 73 dB noise level is slightly elevated for single-stage operation. Electrical requirements are moderate at 115V, 1 phase, 60 Hz, with a 22-35 amp breaker range.
Pros & Cons
Pros
- 96% AFUE furnace efficiency reduces heating fuel costs significantly compared to 80-90% models
- 14 SEER cooling delivers solid seasonal efficiency with single-stage scroll compressor reliability
- 80,000 BTU heating output handles most residential applications up to 3.5 tons
- Multi-speed blower motor optimizes comfort and efficiency across varying load conditions
- Downflow/horizontal configuration offers installation flexibility in cramped mechanical spaces
Cons
- Not Energy Star certified, missing qualification despite high AFUE and SEER ratings
- Single-stage compressor means less precise cooling modulation and slightly higher operating noise at 73 dB
- Spec sheet lists conflicting tonnage information (product title says 3.5 ton, specs show 5 ton, cooling BTU matches 3.5 ton)
Who Should Buy
Best For
Contractors installing retrofit systems in homes with space constraints and homeowners in moderate climates who prioritize heating efficiency. The downflow design and reasonable 42,000 BTU cooling output work well in split-system retrofits where space is tight.
Consider Alternatives If
Buyers in extremely hot climates needing maximum cooling capacity should look at higher SEER units. Those requiring Energy Star certification for tax credits or rebates should explore qualified alternatives.
Installation
Installation uses standard R410A or R22 refrigerant lines with 3/8-inch liquid and 7/8-inch suction connections. The 3/8-inch insulation thickness on suction lines is adequate for most installations. Plastic/PVC exhaust flue requirement simplifies venting compared to metal alternatives. Downflow configuration requires floor or attic mounting with return air ducting below the unit, limiting placement options in some homes.
Warranty & Reliability
The 10-year warranty requires online registration and covers parts and labor. This is respectable coverage for a mid-range unit, though premium competitors offer comparable warranties. Registration through Online Supply is straightforward and important for claim validation. The Goodman name provides confidence in parts availability should repairs become necessary.
