Review
Goodman continues to deliver value-oriented HVAC solutions, and this 3-ton upflow configuration targets contractors and homeowners seeking efficiency without premium pricing. The system combines an 80,000 BTU furnace with a matching air conditioning unit, packaged in a compact 30-inch height suitable for most basement and closet installations. Online Supply's distribution model keeps costs low, though brand familiarity remains lower than traditional OEMs. The SKU LS38783850 appears designed for the replacement and new construction markets where budget constraints are significant.
Performance metrics are genuinely strong for the price. The furnace delivers 96% AFUE efficiency with two-stage burners, meaning minimal fuel waste during heating season. The cooling side provides 18 SEER2 efficiency through a two-stage condenser and scroll compressor, pulling 35,000 BTU at full capacity. The variable-speed ECM blower motor runs quietly at 71 dBA while delivering up to 1,600 CFM. Energy Star certification confirms efficiency credentials. For contractors in northern markets where heating BTU matters most, the 80,000 heating output paired with 96% AFUE delivers excellent operating cost performance.
Pros & Cons
Pros
- 96% AFUE furnace efficiency with two-stage burners minimizes heating waste in cold climates
- 18 SEER2 cooling efficiency and scroll compressor deliver solid AC performance for the price tier
- Variable-speed ECM blower motor provides better comfort control and quiet operation at 71 dBA
- Two-stage condenser allows modulated cooling for improved efficiency during partial-load conditions
- 10-year warranty with online registration provides reasonable coverage for residential applications
- Energy Star certified system reduces operating costs over time
Cons
- Spec sheet shows conflicting tonnage data, listing both 3 ton and 5 ton which raises manufacturing clarity concerns
- Online Supply branding lacks the market recognition and dealer support network of major manufacturers
- Limited documentation available, requires Adobe Reader for installation manuals which may slow contractor setup
- Cooling BTU specification at 35,000 seems undersized for marketed 3-ton capacity, creating potential oversizing issues
Who Should Buy
Best For
This system works best for contractors building rental properties or flipping homes where upfront cost matters more than brand prestige. Homeowners in heating-dominant climates (northern U.S., Canada) who prioritize furnace efficiency and can accept an unfamiliar brand will see good long-term value.
Consider Alternatives If
Homeowners wanting factory-direct support, established dealer networks, or premium brand recognition should look at Carrier, Lennox, or Trane instead.
Installation
Installation requires 208/230V single-phase 60Hz power with breaker sizing between 21.3 and 35 amps. The upflow/horizontal configuration accommodates both orientations, and the right-side flue location accepts plastic PVC exhaust piping, simplifying ductwork integration. Refrigerant lines use standard 3/8-inch and 7/8-inch connections with sweat valves. Installation documentation is PDF-based, requiring Adobe Reader. Contractors should verify local utility requirements before proceeding, as dual-fuel capability (propane and natural gas) affects burner setup.
Warranty & Reliability
Goodman provides a standard 10-year parts and labor warranty with online registration. This coverage is competitive for the price tier and protects against compressor failure, heat exchanger problems, and component defects. The warranty does not cover refrigerant charges or routine maintenance. Registration documentation must be completed at installation to activate coverage. For homeowners planning to stay long-term, this warranty provides reasonable peace of mind.
