Ac Freon Pressure Too High

Most high pressure readings are a result of the freon or refrigerant not cooling adequately.

Ac freon pressure too high. Needs service possibly faulty compressor. Although mechanics tell owners that the high pressure is due to a problem with the accumulator or evaporator that is not likely the case. Refrigerant does not wear down over time so it must be escaping from somewhere. In this case pressure must be released by a certified mechanic.

Either of these 3 causes will require you to evacuate or vacuum pump the coolant in the system. As we all know the hvac systems is composed of a high and a low pressure side. The orifice tube or expansion valve is the one components in between these two refrigerant conduits.

It is illegal to vent 134a refrigerant into the atmoshpere. Leaks may cause air or water to contaminate the system. You may need to replace pipes or valves to return the system to normal operation. Normally we want the low side pressure to be as low as possible for refrigeration systems.

Therefore if its pressure is too high it could be a sign of underlying problems such as diminishing or leakage of coolant which call for immediate attention. Mechanics often misdiagnose high pressure gauge readings in a car s air conditioning system. Another possible cause of too much high pressure might be the piping system has leaked or has the incorrect use of refrigerant oil. The other usual cause of high pressure readings is that the entire ac system may be overcharged which happens either when there is too much refrigerant or too much oil.

Effects of too much refrigerant in the system overcharging over metering or other high refrigerant pressure situations.
