The compressor is the heart of an air conditioning unit. It compresses the refrigerant gas, making it very hot, and then passes it onto the condenser to cool it down.

The compressor works by sucking in refrigerant from the evaporator under low pressure and then compressing it, sending it to the condenser under high temperature and high pressure. This process is essential for the air conditioning system to function.

As the refrigerant is compressed, it gets hotter and is then cooled by the condenser coil outdoors. This cycle of compression and cooling is what makes the air conditioning unit work.

Air conditioning works by removing heat from inside your home and transferring it to the outdoors using a cooling agent called refrigerant. This refrigerant changes from a liquid to a gas as it absorbs heat, and it's the compressor's job to pump it through the AC system.

The compressor squeezes the molecules of the refrigerant together, compressing it into a hot liquid that's then cooled by the condenser coil outdoors. This process is essential for cooling your home.

As the refrigerant goes back to the evaporator, pressure is reduced at the expansion valve, allowing it to absorb heat easier and turn into a gas. This helps maintain the cooling cycle.

A faulty compressor can cause the outdoor unit to overheat, which can be prevented by ensuring it has at least three feet of space on all sides for proper airflow. I've seen this firsthand in my own home, where a clogged area led to a malfunctioning compressor.

The compressor does exactly what it sounds like: it compresses the refrigerant gas, making it very hot, which is then cooled by the condenser. This process is repeated continuously to maintain a cool temperature in your home.
