Where does the pressure go in an air conditioner?
Your air conditioning system is split in half when it comes to pressure. Your air conditioning system holds a very high pressure between your AC compressor and condenser up expansion valve, and a relatively low pressure after the expansion valve and evaporator and back to the inlet of the compressor.
Is there a way to measure air conditioner pressure?
These gauges are relatively accurate and an inexpensive way to measure the low side pressure in your system. Unfortunately, the low side pressure is just one piece of the puzzle. Your air conditioning system is split in half when it comes to pressure.
Why does my AC compressor not turn on?
When the compressor turns on it should lower the pressure on the low side of your system and that pressure again is dependant on ambient temperature and other factors. If the pressure isn’t lowering in your system with the AC switched on, then either your compressor isn’t running, or it has an internal failure.
What does it mean when your AC pressure is low?
A low pressure on the low side could also indicate a clog somewhere in your system. If you find a higher than usual low side pressure it usually is an indication of a failed compressor, but it’s also possible that your system is simply overfilled if you’ve recently added refrigerant.
What do I need to install an AC compressor?

How do you replace a low pressure air conditioner hose?
In order to replace hoses or any components of an AC system, you need to have specialized equipment to remove the refrigerant and pressure from the lines. Noted below are the materials and tools you’ll need to complete this repair. Warning: The steps noted below are GENERAL STEPS for replacing the AC low pressure hose.
How can I replace my a / C pressure switch?
In order to safely and efficiently replace your A/C pressure switch you need a couple of basic tools: Free repair manuals – Autozone provides free online repair manuals for certain makes and models Step 1: Locate the A/C pressure switch. The pressure switch can be mounted to A/C pressure line, compressor or accumulator/drier.
What should the pressure be on an AC charger?
After determining the correct pressures using the ambient air pressure chart, monitor the pressure readings constantly while charging the system. If the system was low, your AC compressor clutch will not engage. You should notice that as the low-side pressure reaches approx. 25-30PSI, that the compressor clutch will engage.
