AC pressure too high on low side
Alfredo’s question:
What to do when you check your ac and pressure is too high (on red)
Answer:
I assume you mean red on the pressure gauge. That means the pressure is too high in the system. I also assume you mean red on the low pressure side (where you add refrigerant.) Common low side problems that cause high pressure are a broken compressor, a bad expansion valve, or cooling fans that aren’t operating correctly. Good Luck,
