My high and low pressure r134 readings are 90-95 each.what should the refrigerant r134a high and low pressure readings be?

If the pressures are always equal running, the compressor is bad and would need replaced

What should hvac gauges read?
HVAC gauges should read the system's refrigerant pressure and temperature. The exact readings will vary based on the specific circumstances and type of system being used. It is important to refer to the manufacturer's guidelines or consult a professional for accurate interpretation of the readings.
How much should be Condenser pressure in an ac with r-22 refrigerant?
300psi
What should the low side refrigerant pressure be on a refrigerator while it is running?
70
What safety precaution should be adhered to for low pressure system?
do not siphon refrigerant by mouth
What should the low pressure be on a hvac system?
The pressure should be equal to a saturated suction temperature of around 40*F. The pressure would differ depending on which refrigerant is used.
What is the refrigerant pressure on the low side for the ac?
R134a refrigerant pressure should be around 28-32 psig with good airflow across condenser(radiator)coil and engine rpm at or around 1500
What is the correct suction pressure when charging a freezer using Refrigerant 134a?
Negative 30 psi should do it.
Is 143 over 84 blood pressure ok?
The 143 over 84 blood pressure is not okay. You should however ave at least three readings and talk to your doctor.
Where is the compressor cycling switch on a 2001 Chevy Tahoe?
It isn't so much a "cycling switch" as a pressure sensor. When refrigerant pressure drops below a specific pressure the sensor turns the compressor off. Since the sensor is on the "low side" of the refrigeration system, pressure can drop once the compressor pumps refrigerant to the "high side", then once the refrigerant is allowed past the orifice, the pressure will build up again on the "low side", and the compressor will briefly turn back on. If that's what's going on with your AC system, have the refrigerant tested and add some if necessary. That SHOULD solve your problem.
When should refrigerant be removed from the condenser outlet?
Refrigerant should be removed from the condenser outlet when:
You have a subaru legacy 1991 the ac stopped working the compressor is engaging on and of constantly did put cooling in it but still dus not work Have anybody any idea where to look for the problem?
If you added refrigerant, was the compressor running better before or after you added refrigerant? Compressor cycling on-off can be caused by defective low pressure switch (very rare on Subarus), or low on refrigerant. Best to test with a good refrigerant gauge-- resting pressure (system off) should be between 45 and 80 psi (higher pressure with higher temperature) on the suction side. Make CERTAIN you attach the gauge to the suction side (the side with the larger diameter hose). When the compressor cycles on, if suction pressure drops below approx 23-29 psi, the low pressure switch will shut off compressor to prevent damage. If low suction pressure, cure is to add refrigerant, little at a time. NOTE: Refrigerant is under high pressure, and is very dangerous. If you are not trained to handle refrigerant, suggest take this problem to a shop to check out.
The 134 a refrigerant hose not fit your 1997 Olds Achieva?
Are you sure you're connecting to the low pressure line instead of the high pressure line? The low pressure line should have a blue or black dust cap on it, while the high pressure line should have a red dust cap on it.
