What causes high-pressure in a car AC system?
Mechanics often misdiagnose high-pressure gauge readings in a car’s air-conditioning system. Most high-pressure readings are a result of the freon or refrigerant not cooling adequately. Insufficiently cooled freon automatically causes the pressure to increase.
What should low side pressure be on Honda Accord?
Not sure how reliable it is but it read 32 PSI; ambient temp was 85F with ~50% humidity. I know high side pressures are needed to get the full picture. I read around and some say 35 PSI is where Accord’s should lie on a high heat load 90F day. Any A/C experts in the house that can comment on the ideal PSI range?
Why is my AC high side pressure not correct?
The correct reading will display once the clutch engages and the gauge stops cycling. If there are readings on both the high and low sides but they are not the correct specified pressures, it means that certain parts of the AC system are not functioning properly, such as the expansion valve, compressor, and clutch.
Why does my air conditioner have low pressure?
There could be several causes leading to this condition including compressor issues, low-level of refrigerant, trouble with the heater or AC controls, and others. One symptom indicating a complication in the air conditioning is AC low side high, high side low pressure.
How can I Check my AC low side pressure?
Just follow the user instructions of the pressure gauge to read your AC’s high side and low side pressure. The correct pressure readings depend on what car you have, and you can find the correct numbers out from your car manual. Here’s a simple guide that you can use to compare your readings with:

What should the pressure be on my a / C compressor?
If you think that you have an issue with your A/C system but you are not sure which component is causing the malfunction it is a good idea to hook your compressor up to a pressure gauge. An A/C System that is working properly should have 150 PSI on the high side and 30 PSI on the low side.
