Review
The Goodman 3-ton combo system arrives as a budget-conscious entry point into two-stage cooling and heating. Priced at $504, it targets contractors and homeowners replacing aging equipment without premium budgets. Online Supply backs this unit with full documentation and Goodman's established service network. The upflow A-coil configuration addresses common retrofit constraints where equipment footprint matters significantly.
Performance numbers tell a practical story. The 17 SEER1 cooling rating and 35,000 BTU capacity handle moderate residential loads efficiently, while the 100,000 BTU furnace at 80% AFUE covers heating needs adequately outside extreme cold regions. Two-stage operation on both sides reduces cycling losses. The scroll compressor uses R410A refrigerant with 3/8-inch liquid and 7/8-inch suction lines, requiring 21.3 to 35-amp electrical service at standard 120V, 1-phase, 60 Hz residential supply.
Pros & Cons
Pros
- 17 SEER1 rating exceeds many budget systems, delivering measurable energy savings on cooling costs
- Two-stage condenser and burner system reduces runtime and improves comfort through modulation
- Variable-speed blower motor maximizes efficiency across load conditions up to 2000 CFM
- Compact dimensions (34.5 inches height, 21 inches wide) fit tight attic and closet spaces
- 10-year warranty with online registration provides solid consumer protection for the price point
Cons
- 80% AFUE heating efficiency lags modern systems, though adequate for moderate climates
- 3.5-ton actual tonnage conflicts with marketed 3-ton rating, creating specification confusion
- 71 dB noise level runs slightly higher than premium two-stage systems during operation
Who Should Buy
Best For
Budget-conscious homeowners in HVAC zones 4-7 who prioritize cooling efficiency and need straightforward upflow installation. Rental property owners and contractors seeking cost-effective equipment replacements will appreciate the balance between performance and affordability.
Consider Alternatives If
Buyers in cold climates needing high-efficiency heating should pursue 90%+ AFUE units, and sound-sensitive homeowners should audition units below 70 dB first.
Installation
Installation complexity sits moderate. The sweat-type valve connections demand soldering competency or professional service. Upflow orientation suits attic placement easily. Metal exhaust flue requirement ensures proper gas furnace venting. The 50-foot suction line with 3/4-inch insulation thickness provides flexibility for unit placement away from condensers. Variable-speed blower requires proper ductwork balancing to optimize the 2000 CFM maximum airflow.
Warranty & Reliability
Goodman includes 10-year parts warranty upon online registration, a significant consumer benefit at this price tier. Registration typically takes minutes through Goodman's portal. Covers compressor, heat exchanger, and components against manufacturing defects. Labor costs remain customer responsibility. This warranty positions the system favorably for homeowner purchases and protects rental properties effectively.
