Understanding the AC Blower System 24 Hour Emergency Heating Service Near Ac Service Ac Hvac Repair Near Me

Before diving into the repair process, it’s important to understand how the AC blower system works. The blower is typically located inside the indoor unit of your AC system, often in the air handler. Its primary function is to draw air from the return vents, pass it through the evaporator coil (where it’s cooled), and then distribute the cooled air through the supply vents into your living spaces.
