Review
This 5-ton Goodman system bundles a furnace and air conditioner into a single downflow package, appealing to homeowners and contractors seeking straightforward efficiency without complex logistics. Online Supply positions this as an ENERGY STAR qualified unit at an accessible price point, making it competitive against split systems in the mid-range market. The combination of high-efficiency heating and respectable cooling performance addresses the dual-season needs of temperate climates effectively.
The furnace delivers 100,000 BTU input with 97% AFUE, meaning almost all fuel converts to usable heat rather than waste up the flue. The air conditioner produces 54,000 BTU cooling capacity with a 16 SEER2 rating, comfortably exceeding ENERGY STAR thresholds. The variable-speed ECM blower motor reaches 2,000 CFM maximum and runs quietly at 73 dB. A modulating burner and scroll compressor provide incremental performance adjustments, though cooling remains single-stage rather than multi-capacity.
Pros & Cons
Pros
- 97% AFUE furnace efficiency significantly reduces heating fuel consumption and monthly costs
- 16 SEER2 cooling rating exceeds ENERGY STAR requirements, supporting rebate eligibility
- Modulating gas burner adjusts output precisely, improving comfort and efficiency compared to single-stage units
- Variable-speed ECM blower motor adapts airflow for quiet operation and better humidity control
- 10-year warranty with online registration provides solid protection against manufacturing defects
- Compact 21x21x30 inch footprint and 48 lb weight accommodate tight basement or attic installations
- Scroll compressor is proven technology with excellent reliability track record
- Downflow/horizontal configuration offers installation flexibility for various home layouts
Cons
- Single-stage cooling compressor cannot modulate like premium models, reducing part-load efficiency
- 73 dB noise level is moderate, higher than variable-capacity systems in light cooling demand
- Specs list 54,000 cooling BTU but header states 5 tons, creating minor documentation inconsistency
- PVC exhaust requirement limits furnace placement options compared to metal flue designs
Who Should Buy
Best For
Homeowners in moderate climates seeking a balanced efficiency upgrade without premium system costs, and contractors building affordable all-in-one solutions for budget-conscious clients. This system works well for homes where heating and cooling demands are fairly consistent.
Consider Alternatives If
Those in extreme climates needing variable-capacity cooling, homes with very tight acoustic requirements, or anyone planning to stay under 10 years who cannot register the warranty.
Installation
Downflow configuration requires positive-pressure ducting below the unit, common in slab or attic layouts. PVC exhaust venting is mandatory, simplifying flue work compared to Category IV furnaces. The 115V, 60Hz electrical demand requires a 29.6 to 50 amp breaker, standard for most homes. Refrigerant lines use 3/8 inch liquid and 1 1/8 inch suction connections with 1/2 inch insulation rated for 50 feet run length.
Warranty & Reliability
Goodman provides 10 years of parts coverage when you register the system online, a customer-friendly requirement that's straightforward to complete. This protects against compressor failure, heat exchanger cracks, and other manufacturing defects. Labor coverage is not specified in this listing, so confirm details with your contractor or retailer before purchase.
