Chrysler, air conditioning system pressure diagnosis in Tel Aviv District.
Air conditioning system pressure diagnosis implies checking its tightness and leaks at high pressure. Pressure diagnosis is required in the following cases: after conducting repairs that imply opening the air conditioning system, frequent refueling of the air conditioning system, for finding freon leaks. The air conditioning system pressure diagnosis is carried out by the nitrogen supply method. When the required pressure is reached, the supply is stopped, and the pressure is evaluated: if it does not drop, then the system is tight.
