Your HVAC system includes several components that work together to keep your home?s air quality comfortable. That said, it is easy to get confused with what these components all do. As it happens, your HVAC system has three major components: the outdoor unit, the indoor unit, and the air handler. The air handler is such an important part of an HVAC system. And yet, many of our Pasadena clients do not know much about it, let alone what it does exactly. Fortunately, our BBB-rated HVAC technicians explain all about this important appliance.
