You need to specify what kind of system. Automotive AC systems and home AC systems use different refrigerants. That, along with the temperature/pressure relationship and ambient air temperature, all factor into what your high pressure (and, consequentially, low pressure) side should read on your manifold pressure gauge.

What does high-side and low-side mean with respect to car AC's?
High side and low side refer to the pressure in the ac system. Ie The high side is the high pressure line and low side is the low pressure line.
What side is the ac condenser on a unit?
The high pressure side.
What should the pressure be on the low and high sides of a working AC in a 2003 Mitsubishi Galant?
HIGH SIDE....YOUR VALVUE TO PUT IN FRE. SHOULD BE DONE ON THE LOW SIDE
Residential ac opperating pressure?
pressurre on low side should be be 70 psi and on high side depending on unit should be between 250 and 350
Where is the low side charge fitting on a 2003 Chevy Tahoe?
The low pressure side of the ac system is the ac hose that runs from the inside of the vehicle to the ac compressor. The high pressure side runs from the ac compressor to the condensor in front of the radiator. Follow the ac hose from the compressor back to the body and you will find the charge fitting. It is smaller in diameter than the high pressure side. You would need a different adapter to hook up to the high side.
What are the symptoms of a bad ac compressor on a 98 Lincoln town car?
The symptoms of a bad ac compressor would be a grinding or rattleing sound or a low pressure reading on the high side with a normal pressure reading on the low side. The low pressure will be about 30 to 40 pounds. The high side should read around 150 to 200.
What are the normal pressure of your home ac unit?
300psi high side and 80psi low side
What is the ac pressure on a Ford Contour?
Low side pressure is normally 28-38 high side pressure is typically 100 + outside temperature
How do you replace an AC Orifice Tube in a 1995 Chevy Blazer?
it's in the high pressure side of the ac line
Where is low pressure ac recharge port on a 1992 ford f150?
left side on firewall should be on the side of ac condencer
Is the ac line under pressure and if so how do you relieve it to replace the compressor?
Yes the ac lines are under pressure. The high side is under dangerously high pressure. The Freon needs to be removed by a reclaiming machine and the pressure will be removed.
What is wrong when an ac system has low side pressure but no high side pressure?
When an AC system has low side pressure but no high side pressure, it typically indicates a blockage or restriction in the system, potentially in the expansion valve or the condenser. This issue can prevent refrigerant from circulating properly, leading to inadequate cooling. Alternatively, it may suggest a refrigerant leak, causing the system to lose its ability to maintain pressure in the high side. It's crucial to diagnose and address the problem to avoid further damage to the AC system.
