What does high pressure on AC compressor mean?
The compressor may be faulty. Higher Pressure on both the High and Low side may indicate an overcharge or lack of cooling at the Condenser. Higher than normal pressures on both high and low side with the correct amount of refrigerant, could mean a problem with air flow thru the condenser.
Why is my AC blowing hot and cold at the same time?
It was blowing cold at all times. Now this afternoon the temp is back to 90 and pressure is reading 120 and blowing hot at idle again until rpms are increased then pressure is going down to around 40 and starts blowing cold again. when the pressure is high like that on the low side, your compressor is likely not engaged.
When do you need a new AC compressor?
If this is the case, you will most likely find the clog in the accumulator or the condenser. If you don’t have a large enough pressure increase across your compressor you may be in need of a new AC compressor. If you have lower than expected pressures on the low pressure side of your system, may simply have a low refrigerant level.
Why is my air conditioner compressor not working?
The compressor may be faulty. Higher Pressure on both the High and Low side may indicate an overcharge or lack of cooling at the Condenser. Higher than normal pressures on both high and low side with the correct amount of refrigerant, could mean a problem with air flow thru the condenser. Is the condenser or cooling fan working?

How does the blend door work on an AC system?
During AC COLD operation, the “Blend Door” routes the cold air around the heater core. During Heat operation, all the air passes thru the Evaporator and the Heater Core. When the temperature is set in between, part of the air will pass thru the Heater Core.
What should AC low side high side low pressure be?
On the other hand, there is possibly a huge leak when the pressure is zero. AC Low Side High, High Side Low: Why Does This Happen? The pressure reading from the low side should be between 25 and 30 psi and the high side between 200 and 250 psi.
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.
Why is the pressure on my a / C so high?
Heat from the radiator transfers to the condenser and cause the pressure to rise due to the warmer refrigerant. It is possible the space between the radiator and the condenser has become clogged with debris.
On the other hand, there is possibly a huge leak when the pressure is zero. AC Low Side High, High Side Low: Why Does This Happen? The pressure reading from the low side should be between 25 and 30 psi and the high side between 200 and 250 psi.
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.
Why does my air conditioner say high and low pressure?
Compressor (engine) RPM and airflow across the condenser are always changing, thus engine speed is always affecting pressure. System design, blower speed, mode setting, refrigerant type, all cause variance in high and low side pressure. For this reason we simply can’t say 30 on the low side and 200 on the high side.
How does a high pressure AC system work?
To measure the pressure in the high-pressure side of your system, you need a little fancier piece of equipment. The pressures in the high-pressure side of your system are so high that it requires special hoses and connections along with a special gauge to contain the pressure and ensure you don’t release any of the refrigerant to the atmosphere.
