Air Handler Units

An air handler unit (AHU) is a critical component of any HVAC system. It is responsible for circulating air throughout the home or building and regulating the temperature. An AHU is composed of a blower, filter, and coil, and is typically connected to a furnace or air conditioner. The blower is responsible for pushing air through the filter and coil, which helps to remove contaminants and regulate the temperature. The filter is responsible for trapping dust, dirt, and other airborne particles that can affect air quality. The coil is responsible for cooling or heating the air depending on the temperature setting. The air handler unit is a vital part of any HVAC system and helps to ensure a comfortable environment.
