Collection: Upflow Furnaces
Shop Upflow Gas Furnaces for Basement and Closet Installs
An upflow furnace pulls air in from the bottom and pushes heated air upward, making it the right choice when your ductwork runs above the unit, as it does with a basement or first floor closet setup. Shop Goodman and ACiQ upflow gas furnaces, including eco friendly R32 refrigerant equipment and propane compatible models, all with free shipping. Upgrade your system with complete gas furnace and AC combos to maximize year round efficiency. If your ductwork sits beneath the floor in a crawl space or manufactured home, explore our downflow furnaces to find the exact airflow configuration for your layout.
