Refrigerant is a chemical compound that absorbs heat when it evaporates, and rejects heat when it condenses. The refrigeration effect is achieved by letting the refrigerant go back to the compressor inlet with some extra energy (heat).
When you kick on your air conditioner, you give power to the compressor inside your system. The motor of the compressor gets hot. Once it's done spinning, there's still pressure left in there called head pressure. That means there are gases pushing out against something trying to contain them. When this happens, they need somewhere else to go so they can be condensed again. Where do they go? They push through tiny little holes in the valve coils and shoot right into your home. When the refrigerant goes inside your house, it's pushed through a coil which causes heat to escape so the gas can be condensed. That process is called cooling your home.
Refrigerants are an important part of your new AC system. They keep the air fresh and cool while its working to improve the temperature in your home. They keep the air fresh and cool while it works its magic to improve the temperature in your home.
