Sabi ko pa naman sa a/c technician kung pwede ko ba malaman, kung sapat ang karga o kulang ng freon sa a/c system ng car ko. Ang kinabit yung low pressure gauge lang, di pa kinabit ang gauge para sa high. Watching the gauge, while the pressure reach 45psi, the a/c compressor automatically engage. At that point, while the compressor is running or activated, it slowly decreases its pressure until it reaches 35 psi, and it disengage the compressor from running.
