Review
This Goodman system combines a high-efficiency gas furnace with a variable-speed cooling unit, targeting homeowners and contractors seeking reliable performance without premium pricing. Online Supply positions it as an entry point into advanced HVAC technology, with modulating burners and two-stage compressor design. The system qualifies for Energy Star certification, which carries weight with energy-conscious buyers and opens doors to utility rebate programs. Available in upflow and downflow configurations, it fits most residential installations. The 10-year warranty with online registration provides reasonable coverage for the mid-market segment.
Performance numbers stand out here. The furnace delivers 120,000 BTU of heating with 97% AFUE efficiency, meaning 97 cents of every energy dollar converts to usable heat. Cooling capacity reaches 35,000 BTU at 18 SEER2, beating the minimum Energy Star threshold of 15 SEER2 by 20%. The modulating burner adjusts output across a continuous range rather than cycling on and off, reducing temperature swing by an estimated 2-3 degrees. The variable-speed ECM blower operates at 2,000 CFM maximum and intelligently throttles down during low-load periods, cutting fan energy consumption from 800-1,000 watts to 100-200 watts. Refrigerant R410A is industry standard.
Pros & Cons
Pros
- 97% AFUE furnace efficiency reduces heating costs significantly compared to 80-90% units, saving $200-400 annually on natural gas or propane
- 18 SEER2 cooling efficiency qualifies for Energy Star certification and local utility rebates, typically offsetting $500-1,500 of system cost
- Modulating furnace burner adjusts output in real-time, eliminating temperature swings and improving comfort during shoulder seasons
- Variable-speed ECM blower motor runs at optimal speed for each cycle, consuming 75% less electricity than fixed-speed motors
- Two-stage compressor ramps down in mild conditions, extending component life and reducing wear by 30-40% versus single-stage units
- Scroll compressor design is proven reliable across Goodman's portfolio with low failure rates in field data
Cons
- Spec sheet shows conflicting tonnage data: header states 3 Ton but specs list 5 Ton, creating confusion about actual system capacity
- Cooling capacity of 35,000 BTU does not align cleanly with labeled 3 Ton rating (36,000 BTU standard), suggesting possible data entry error or non-standard configuration
- 71 dB noise level is moderately loud during full-load operation; sound-sensitive homeowners may want additional vibration isolation pads
Who Should Buy
Best For
Homeowners in cold or mixed climates replacing 15+ year old furnaces or adding cooling to heating-only homes will see immediate energy savings. Contractors building new homes or commercial light-duty properties benefit from the rebate eligibility and streamlined two-stage installation process.
Consider Alternatives If
Buyers in consistently warm climates should prioritize high-SEER cooling units over furnace efficiency. Anyone requiring a specific tonnage should confirm actual capacity with Online Supply before purchasing due to spec inconsistencies.
Installation
Installation requires 115V single-phase 60Hz power with breaker sizing between 21.3 and 35 amps, standard for residential circuits. PVC or plastic flue venting simplifies ductwork routing and reduces installation labor. The unit measures 30 inches tall by 24.5 inches wide by 21 inches deep, fitting most utility closets or basements. Suction line insulation is pre-fitted at 3/4 inch thickness. Liquid and suction line sizes are 3/8 inch and 7/8 inch respectively, matching common refrigerant tubing.
Warranty & Reliability
Coverage extends 10 years from purchase upon completing online registration, a standard practice across mid-tier manufacturers. Registration is simple but non-negotiable for claim eligibility. This timeframe aligns with typical compressor and heat exchanger expected life in residential applications. Parts labor is generally excluded, covering manufacturing defects only.
