An air handler is an important part of your home’s comfort system. Your central air conditioning system consists of two main parts—an outdoor unit and an indoor unit. The air handler is the indoor unit and its job is to effectively circulate conditioned air throughout your home. When matched with a heat pump, it circulates both cool and hot air, depending on the season. With properly sized Trane air handlers, your family has the right amount of clean, comfortable air all year round. Plus, Trane air handlers make a significant contribution to the overall efficiency of your system. That’s because the more efficient your air handler is, the less work your outdoor unit has to do to make your home comfortable.
