Review
This 3-ton Goodman combination system represents solid middle-market value in the residential HVAC space. Online Supply prices it at $732, positioning it below boutique brands while maintaining respectable efficiency specifications. The downflow A-coil configuration addresses a specific installation niche, particularly useful for retrofit jobs where space constraints or existing ductwork favor horizontal airflow. Variable-speed blower technology and modulating gas burners signal this isn't a basic budget unit.
Performance numbers stand out for the price point. The furnace delivers 80,000 BTU heating capacity at 97% AFUE, meaning 97 cents of every gas dollar converts to usable heat. The air conditioning side produces an 18 SEER1 rating with two-stage compression, translating to roughly 25 to 30 percent lower cooling costs versus 14 SEER baseline equipment. The 71 dB noise level keeps operation reasonably quiet. Variable-speed ECM motor delivers up to 1,200 CFM while automatically adjusting to load requirements, improving comfort consistency throughout the heating and cooling seasons.
Pros & Cons
Pros
- 97% AFUE furnace efficiency with modulating burners maximizes heating season performance
- 18 SEER1 cooling rating (18 vs the advertised 17 SEER) meets ENERGY STAR standards for qualifying rebates
- Two-stage scroll compressor with variable-speed ECM blower reduces runtime noise to 71 dB
- Dual-fuel capability supports natural gas and propane for flexible installation options
- PVC plastic exhaust flue compatibility reduces installation costs compared to metal venting
Cons
- Cooling capacity listed as 35,000 BTU conflicts with 3-ton rating, creating specification ambiguity for contractors
- 10-year warranty requires online registration, which some buyers find inconvenient or miss
- Limited to 1,200 CFM maximum airflow may feel undersized in homes with poor ductwork or large open layouts
Who Should Buy
Best For
Contractors installing replacement systems in homes with existing downflow or horizontal configurations, and budget-conscious homeowners in HVAC rebate programs. This system works well for moderate-climate regions where heating and cooling loads are balanced.
Consider Alternatives If
Anyone needing a 5-ton or larger system, homes requiring upflow-only installation, or buyers seeking premium extended warranties beyond 10 years.
Installation
Installation requires standard HVAC connections, 115V single-phase power, and breaker sizing between 21.3 and 35 amps. The downflow design suits basement utility areas or sideways closet installations common in modern construction. PVC venting simplifies exhaust routing compared to metal pipes. Technicians should verify ductwork matches the 1,200 CFM maximum output and that return air sizing accommodates the variable-speed blower without excessive static pressure.
Warranty & Reliability
Goodman covers this unit for 10 years from purchase date with online registration, a straightforward process most dealers complete at installation. This duration is standard for mid-tier residential equipment, though some competitors offer 12-year options. Coverage includes parts and labor through registered installers, though homeowners should confirm their installer participates in the Goodman parts network.
