Built under the RunTru by Trane product line, this furnace is engineered for residential upflow and convertible horizontal-right or horizontal-left installations. A multi-speed blower motor supports balanced airflow across varied duct configurations. Licensed HVAC technicians install this unit as a primary heating system in forced-air residential applications where dependable mid-efficiency performance is required.\u003c\/p\u003e\n\u003cp\u003eThis furnace is suited for residential forced-air heating systems where a 24.5-inch wide upflow cabinet fits the mechanical room or closet layout. The unit converts to horizontal-left or horizontal-right orientation, expanding its range of installation scenarios including crawlspace and attic applications. It operates on natural gas and pairs with standard split-system cooling equipment in a typical upflow configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120,000 BTU\/h input with 95% AFUE for efficient natural gas combustion\u003c\/li\u003e\n  \u003cli\u003eSingle-stage gas valve for straightforward, reliable heating operation\u003c\/li\u003e\n  \u003cli\u003eMulti-speed blower motor accommodates varied static pressure and airflow demands\u003c\/li\u003e\n  \u003cli\u003eUpflow cabinet convertible to horizontal-right or horizontal-left orientation\u003c\/li\u003e\n  \u003cli\u003eIntegrated furnace control board with 7-segment LED display for diagnostics\u003c\/li\u003e\n  \u003cli\u003eCondensing design recovers latent heat from flue gases for higher seasonal efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM upflow and convertible horizontal condensing gas furnace replacement or new installation unit within residential forced-air systems.

Shut off gas supply and disconnect electrical power at the service disconnect before beginning any work on or near the unit. The condensate drain lines must be properly pitched and terminated per local plumbing codes, as this is a condensing furnace that produces acidic condensate. Do not operate the furnace without verifying proper venting, gas pressure, and low-voltage control wiring connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Capacity\u003c\/strong\u003e: 120,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Capacity\u003c\/strong\u003e: 114,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 95%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStaging\u003c\/strong\u003e: Single Stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlower Motor\u003c\/strong\u003e: Multi-Speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow Orientation\u003c\/strong\u003e: Upflow, Convertible to Horizontal Right or Horizontal Left\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCabinet Width\u003c\/strong\u003e: 24.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCabinet Depth\u003c\/strong\u003e: 28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFurnace Type\u003c\/strong\u003e: Condensing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Line\u003c\/strong\u003e: RunTru by Trane\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Trane\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A951X120DU5SA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51217053057330,"sku":"A951X120DU5SA","price":2178.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308796045.jpg?v=1780588817","url":"https:\/\/voomisupply.com\/products\/runtru-a951x120du5sa-gas-furnace-120k-btu-95-afue-single-stage","provider":"Voomi Supply","version":"1.0","type":"link"}
