Review
Goodman's 97% AFUE gas furnace and two-stage air conditioner system represents a solid mid-to-premium offering for homeowners seeking reliable HVAC equipment with legitimate efficiency credentials. The unit carries Energy Star certification, modulating burner technology, and scroll compressor cooling, positioning it as a sensible choice for mixed climates where both heating and cooling matter. Online Supply sources this as a complete system package suitable for downflow or horizontal installation in most residential applications.
The furnace delivers exceptional heating efficiency at 97% AFUE with modulating burners that continuously adjust to heating demand, reducing wasted fuel compared to on-off cycling. Cooling performance reaches 18 SEER2 using R410A refrigerant and a scroll compressor with two-stage staging. The variable-speed ECM blower motor maxes out at 1,600 CFM, matching airflow to actual load requirements. Electrical draw stays reasonable at 115V single-phase operation with breaker requirements between 21.3 and 35 amps, fitting standard residential service panels.
Pros & Cons
Pros
- 97% AFUE furnace with modulating burners reduces heating costs significantly compared to single-stage units
- 18 SEER2 air conditioner rating exceeds federal minimum efficiency standards for enhanced cooling performance
- Variable-speed ECM blower motor with 1,600 CFM maximum capacity improves temperature consistency and lowers electricity use
- Two-stage scroll compressor operates quietly at 71 dBA, reducing noise complaints from neighbors and family
- Energy Star certified system qualifies for utility rebates and tax incentives in many regions
Cons
- Specs show conflicting tonnage (3 Ton in title versus 5 Ton in data), creating confusion during specification
- Cooling BTU of 35,000 undershoots the 3-ton rating (36,000 BTU standard), suggesting possible undersizing
- No pricing information listed makes cost comparison impossible for budget-conscious buyers
Who Should Buy
Best For
Homeowners in cold to temperate climates who prioritize heating efficiency and want to minimize natural gas bills without sacrificing cooling comfort. This system suits those willing to invest in premium efficiency equipment with rebate eligibility and long-term operational savings.
Consider Alternatives If
Budget-conscious buyers shopping primarily on upfront cost should look at standard 14 SEER systems, and anyone in hot climates should seek higher cooling capacity than this unit appears to deliver.
Installation
This downflow A-coil configuration requires careful placement in crawlspaces or attics with adequate return air clearance. Connections include 3/8-inch liquid line and 7/8-inch suction line with 3/4-inch insulation on suction. The plastic PVC exhaust flue vents to the right side. Standard HVAC installation skills apply, though the modulating burner control board warrants careful configuration during startup.
Warranty & Reliability
Online Supply provides 10 years of parts coverage with product registration, covering compressor, control boards, and heat exchanger defects. This warranty period exceeds the industry standard 5-year baseline, providing meaningful protection for compressor failures and major component degradation. Registration requirement demands attention during installation.
