Review
The Goodman 3-ton combo system represents a practical middle ground in the residential HVAC market. At $1,998, this horizontal unit bundles furnace and air conditioning in one package, simplifying installation and reducing connection points. It's pitched at contractors and homeowners who need functional equipment without luxury features. The horizontal mounting means it fits attics, basements, or crawlspaces where space is constrained. Goodman's brand recognition among contractors provides reassurance, though this model sits squarely in the value tier rather than the performance tier.
Performance metrics show competent, if unspectacular, engineering. The air conditioner delivers 36,000 cooling BTU at 14 SEER efficiency, meaning a 3-ton system cools effectively while consuming less power than older 10-11 SEER equipment. The furnace produces 60,000 heating BTU at 80% AFUE using natural gas or propane. Two-stage burner operation and variable-speed blower motor allow some modulation for efficiency, but the single-stage compressor on the cooling side doesn't match demand as intelligently as premium units. The 73 dBA noise level is moderate for comfort.
Pros & Cons
Pros
- 14 SEER cooling efficiency provides meaningful savings on summer electric bills compared to older 10-13 SEER units
- Two-stage burner with variable speed blower reduces short cycling and improves comfort during mild weather
- 36,000 cooling BTU and 60,000 heating BTU properly matched for 3-ton applications
- Horizontal configuration fits tight attic or crawlspace installations where vertical units won't work
- 10-year warranty with online registration covers parts and labor comprehensively
Cons
- 80% AFUE is entry-level for furnaces, meaning 20% of heating energy is wasted up the flue compared to 95% AFUE models
- Not Energy Star certified, suggesting it meets minimum standards rather than best-in-class efficiency
- Single-stage compressor lacks variable capacity modulation that premium units offer for efficiency gains
Who Should Buy
Best For
Homeowners in moderate climates where heating costs aren't extreme, or contractors installing systems in price-sensitive markets where efficiency premiums aren't justified. This works well for rental properties, secondary residences, or upgrade situations where equipment lifespan matters more than operational costs.
Consider Alternatives If
Buyers in cold climates who heat heavily should look at 90+ AFUE systems, or those prioritizing maximum efficiency should compare 16 SEER+ units despite higher upfront costs.
Installation
This unit requires standard 208 or 230-volt single-phase power with a 30-amp breaker maximum. The horizontal configuration demands careful ductwork planning to accommodate 1,600 CFM maximum airflow. Refrigerant lines use 3/8-inch liquid and 3/4-inch suction connections with 3/4-inch insulation thickness. A metal flue is required for exhaust. The 35-pound weight and 32.5-inch height make it manageable for two technicians in most ceiling spaces. Professional installation is strongly recommended despite straightforward connections.
Warranty & Reliability
Goodman covers this unit with a comprehensive 10-year warranty on parts and labor when registered online. This is solid protection that typically covers compressor failure, heat exchanger cracks, and component defects. Registration is straightforward and often completed during installation. The lengthy warranty period indicates manufacturer confidence in reliability, though coverage is standard across the Goodman lineup rather than extended.
