As I mentioned earlier, the air conditioner compressor is situated outside, and its main duty is to circulate refrigerant.

The refrigerant absorbs the heat from your home and releases the heat to the outside unit through the coils of your air conditioner. If you go in front of your air conditioner compressor, you’ll feel hot air coming from it.

The compressor has a motor in it, and with the help of this motor, the air conditioner compressor compresses the refrigerant and increases the temperature of the refrigerant. When the temperature of the refrigerant rises, it turns into a high-pressure gas. This high-pressure gas forces the refrigerant to go to the air conditioner’s outdoor coil and releases the heat. After releasing the heat, the AC refrigerant turns into a liquid.

Then this liquid refrigerant moves to the indoor unit and turns into a gas again. When it is in a gaseous state, it absorbs the heat from your home and transfers the heat to your air conditioner’s compressor. Thus, your compressor makes your home cool. This cycle continues until your air conditioner reaches your desired temperature.
