A ducted air handler is the "indoor unit" used in traditional central HVAC systems. Unlike a wall-mount, it sits in an attic, basement, or closet and pushes air through a network of ducts. Our Shop All Ducted collection features high-efficiency Heat Pump air handlers that can replace your old gas furnace. These units are much quieter and more efficient than older models, especially when paired with an Inverter Condenser. They are a great choice for whole-home climate control if you already have ductwork in place. You can find technical sizing info in our HVAC Load Calculator. Upgrading to a modern air handler can qualify you for IRA Tax Credits. It’s a powerful way to modernize your entire home’s comfort.
