IL License #2183457What Is an Air Handler?
The Indoor Half of Your HVAC System
An air handler works alongside your outdoor air conditioner or heat pump to circulate conditioned air throughout your home. It houses the evaporator coil, blower motor, and air filter — and its efficiency directly impacts your comfort, humidity control, and energy bills. Lennox air handlers are engineered to match Lennox outdoor units for peak system efficiency, and D's Air & Heating, Inc. installs every model to Lennox factory specifications with permits pulled and warranty registered at installation.
