How AC Works?

How-AC-Works

Air conditioners have two components i.e. an indoor component & an outdoor component. Both components contain entirely different types of coil that need to be cleaned.

There are evaporator coils which are located in the interior portion of the unit. These evaporator coils are made up of copper, which conducts heat easily, and they contain coolant.

These evaporator coils absorb heat since warm air passes over them, and the refrigerant evaporates to a gas state.

After that, the refrigerant transfers the warm air to the outside component, where it passes through the compressor to the condenser coil.

This is the point where the compressor returns the refrigerant to a liquid state. The condenser coil then releases heat with the help of an exhaust fan in the surrounding.

To clean your home AC, you need to  work on both the components of Air conditioner i.e.  indoor and outdoor components.
