The AC coils or the piping system could be why there’s too high pressure. This component could either overheat or freeze depending on the amount of coolant flowing, causing damage to the system hence the high pressure. The expansion valve, located near the evaporator, controls the coolant flowing through the AC system. It’s advisable not to add more coolant or refrigerant to the system when the pressure is too high to avoid damaging the evaporator core. To be sure that the overcharge is causing the high pressure, you must measure the system’s pressure. Overcharging, in this case, has nothing to do with the electrical system but adding too much coolant or refrigerant to the AC unit. The result is the condenser fan being unable to cool the AC system and pass enough air effectively. Since the AC’s condenser fan works at different speeds, an issue associated with this part may reduce its pace and efficiency. Here are the reasons your vehicle is experiencing high AC pressure. A limited airflow or no airflow is passing through the condenser due to blockage.There are several causes of high air conditioner pressure. But if your vehicle’s air conditioner has cooling problems, you’ll discover that the reading from the low side pressure is too high.

Now, with the vehicle’s manual at hand, you can compare the reading on the gauge to the pressure rating for your car to see which side is too high. After connecting it to either side of the compressor, turn on the AC to the maximum and record the gauge’s reading. Connecting this pressure gauge to the compressor’s high side to get the pressure readings is still okay. Once you have the gauge, connect it to the compressor’s low side before you can turn on your car. Buying one isn’t that expensive, costing between 30-50 dollars in the retail market. You need a pressure gauge to help you carry out this assignment. Here is how you can check your AC pressure: You must correct the situation the first time you notice it to avoid further damages. The first part that may fail is the compressor, which is very costly to repair or replace. This situation indicates an underlying issue with the unit, and it’s slowly getting damaged. When the AC pressure is too high, the interior temperature becomes too hot to survive on a sunny day. What Happens When AC Pressure Is Too High? It’s also referred to as the discharge line since it’s through this line that the pressure departs the AC compressor in liquid form. The high side connects to the compressor from the bottom and is usually warm if touched. The low side tube/line usually has a larger diameter than the high side tube. On most vehicles, it has a colored cap, blue or black, that you must remove when recharging the AC system. The low side is the line connected from the compressor to the evaporator. It could be something to do with the compressor or refrigerant added to charge the AC or even a leak in the system.īefore getting deep into the causes, it’s only prudent to touch on an AC system’s low side and high side. This situation could be related to several possibilities.
