- Compressor
The component that compresses refrigerant gas, raising its pressure and temperature, allowing it to flow through the AC system for heat exchange and cooling.
- Condenser
A coil or unit where hot compressed refrigerant releases heat to the outside air, turning from gas into liquid form.
- Evaporator
A coil inside the AC where liquid refrigerant absorbs heat from indoor air, evaporating into gas and cooling the room.
- Expansion valve
A device that regulates refrigerant flow into the evaporator, reducing pressure and temperature for effective heat absorption.
- Refrigerant
A chemical fluid that circulates through an AC, absorbing heat from indoors and releasing it outdoors to provide cooling.
- Blower fan
A fan inside the indoor unit that pushes cooled or heated air through the vents into the room.
- Air filter
A mesh or foam component that removes dust, pollen, and other particles from air before it enters the AC system.
- Thermostat
A device that measures room temperature and controls the AC to maintain the desired temperature automatically.
- Control panel
The interface with buttons or displays that allows users to operate, adjust settings, and monitor the AC system.
- Circuit board
An electronic board that manages AC functions, controlling components like compressor, fan motors, and sensors.
- Drain pipe
A tube that carries condensed water from the evaporator coil outside or to a drain to prevent water accumulation.
- Copper tubing
Pipes that transport refrigerant between AC components, allowing heat exchange and pressure changes efficiently.
- Insulation
Material wrapped around pipes or ducts to reduce energy loss, prevent condensation, and improve AC efficiency.
- Fan motor
The motor that drives the blower or outdoor fan, circulating air for heat exchange in the AC system.
- Outdoor unit
The part of the AC installed outside, containing the compressor, condenser, and fan, responsible for releasing heat to the environment.
- Indoor unit
The component inside the room that houses the evaporator, blower, and controls, distributing cooled or heated air.
- Cooling coil
A coil where refrigerant absorbs heat from indoor air, turning it cooler before the air is circulated.
- Heating coil
A coil that heats air in AC systems with heating function, often using electricity or hot refrigerant.
- Capacitor
An electrical component that stores energy to help start and run the compressor or fan motor efficiently.
- Relay
An electrical switch controlled by a low-power signal, used in ACs to turn on/off compressor or fan motors safely.

Common Parts of Ac with their Names and Pictures
- Sensor
A device that detects temperature, humidity, or other conditions in the room or AC system, sending signals to control cooling or heating operations efficiently.
- Air vent
An outlet through which cooled or heated air is released into the room from the AC system for proper air distribution.
- Louver
Adjustable slats on the AC vent that direct airflow in desired directions for better cooling or heating efficiency.
- Grille
A protective cover with openings on AC units or vents, allowing air to pass while preventing foreign objects from entering.
- Power cord
An electrical cable that connects the AC to the power supply, providing energy for operation.
- Switch
A device that turns the AC or specific components on or off, controlling the flow of electricity safely.
- Display panel
A visual interface on the AC showing temperature, mode, fan speed, and other operational settings for user convenience.
- Remote receiver
A sensor that receives signals from the AC remote control to operate functions like temperature, mode, or fan speed.
- Drain pan
A tray below the evaporator coil that collects condensed water and directs it to the drain pipe.
- Noise damper
A component that reduces sound from airflow or mechanical operation, making the AC quieter during use.
- Mounting bracket
A metal or plastic support used to fix the indoor or outdoor AC unit securely in place.
- Suction line
The refrigerant pipe that carries low-pressure gas from the evaporator back to the compressor.
- Discharge line
The pipe that carries high-pressure refrigerant gas from the compressor to the condenser for heat release.
- Service valve
A valve used by technicians to access, recharge, or maintain the refrigerant system safely during servicing.
- Pressure switch
A safety device that monitors refrigerant pressure and shuts down the system if pressure is too high or low.
- Air duct
A channel that directs cooled or heated air from the AC to different areas of the building.
- Filter dryer
A device that removes moisture and impurities from the refrigerant to protect the AC system from damage.
- Terminal block
An electrical connector that joins wires in the AC system, ensuring proper power distribution to components.
- Transformer
An electrical device that changes voltage to the required level for AC components to operate safely.
- Fan blade
Rotating blades that move air through the AC unit, ensuring proper airflow for cooling or heating.
