That efficiency rating means approximately 76,000 BTU of usable heat output per cycle, with minimal flue loss. The variable-speed ECM blower delivers quieter operation and more consistent airflow compared to single-speed units. This furnace is designed for downflow installations and is part of the RunTru by Trane product line. Licensed HVAC technicians handle installation and commissioning in residential applications.\u003c\/p\u003e\n\u003cp\u003eThe A952V080BD4SA is suited for residential downflow installations, including split systems paired with a matching evaporator coil and outdoor condensing unit. It is compatible with standard 24-volt thermostat control wiring. The unit has been offered as part of a bundled system with a 3.5-ton 14.3 SEER2 air conditioner configuration. Installations requiring a downflow air discharge orientation — such as crawl-space delivery or platform-mount setups — are typical applications for this model.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80,000 BTU input capacity with approximately 76,000 BTU output at 96% AFUE\u003c\/li\u003e\n  \u003cli\u003eVariable-speed ECM blower for quieter, more consistent airflow\u003c\/li\u003e\n  \u003cli\u003eTwo-stage gas valve for improved temperature control and reduced cycling\u003c\/li\u003e\n  \u003cli\u003eDownflow air discharge orientation for platform or crawl-space duct systems\u003c\/li\u003e\n  \u003cli\u003e24-volt control circuit compatible with standard residential thermostats\u003c\/li\u003e\n  \u003cli\u003eHigh-efficiency condensing design with low flue gas temperature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDocumented in a 3.5-ton downflow system configuration with the A4AC4042D1 outdoor condensing unit and 4MXCB006AC6HCB evaporator coil.

Shut off gas supply and disconnect electrical power before any service work. As a condensing furnace, this unit requires a properly pitched PVC condensate drain line and a two-pipe direct-vent flue system — do not connect to a B-vent or single-pipe flue. Verify static pressure and airflow meet design specifications for the installed duct system before startup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Capacity\u003c\/strong\u003e: 80,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Capacity\u003c\/strong\u003e: 76,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 96%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlower Motor Type\u003c\/strong\u003e: Variable Speed ECM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Valve Stages\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow\u003c\/strong\u003e: 1,600 nominal CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Orientation\u003c\/strong\u003e: Downflow\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: A952V080BD4SA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51195713585458,"sku":"A952V080BD4SA","price":2939.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308796096.jpg?v=1780588763","url":"https:\/\/voomisupply.com\/products\/trane-a952v080bd4sa-gas-furnace-80-000-btu-downflow","provider":"Voomi Supply","version":"1.0","type":"link"}
