Understanding the Basics: How an AC Unit Works Emergency Heating Repair Near Me 24hr Air Conditioning Service
Before diving into the repair process, it’s helpful to understand the fundamental principles of how an AC unit operates. The core components of an AC system include: 24 Hour Emergency Heating Service Hvac Furnace Repair
- Compressor: This is the heart of the system, compressing the refrigerant and circulating it throughout the system.
- Condenser Coil: Located outside, this coil releases heat from the refrigerant, turning it from a gas to a liquid.
- Evaporator Coil: Located inside, this coil absorbs heat from the air, cooling it down.
- Refrigerant: This is the fluid that absorbs and releases heat, circulating throughout the system.
- Expansion Valve: This valve controls the flow of refrigerant into the evaporator coil.
- Blower Motor: This motor circulates air across the evaporator coil and throughout your home.
- Ductwork: The network of ducts that distributes the cooled air.
The AC unit works by cycling refrigerant through these components. The refrigerant absorbs heat from the air inside your home, cools the air, and then releases the heat outside. Phoenix Air Conditioning Repair Ac Heater Repair
