Re: refrigeration Quiz
In addition to low charge, you have to first look air air flow over the evaporator. Low air flow, due to plugged filter, dirty coil or fan not operating at speed, will all show a low suction pressure and possibly a frosted coil.
Try to charge a system with a dirty coil and see what you get...
