What causes low refrigerant in car AC?
AC systems operate using two different sides, the high side and the low side. Over time, these pressurized systems can eventually develop leaks. Once any sort of leak has begun, they will eventually cause enough refrigerant to leak out to the point where the AC will no longer be able to produce cold air.
Does low refrigerant cause low-pressure?
Low condensing pressure: Because the evaporator and compressor are being starved of refrigerant, the condenser will also be starved. This lower temperature will cause a lower pressure in the condenser because of the pressure/temperature relationship at saturation.
Where is the low-pressure side of my home AC?
The low side line of the system will have a larger diameter metal pipe than the high-side. The low side service port is usually located between the AC compressor and evaporator. The low side service port will have a black or blue plastic cap that needs to be removed.

How do you refill an AC line in a Jetta?
Smaller of the two fittings – large AC line is suction side – small port – charge here. Small line from compressor is high pressure side – larger of the two ports – monitor high pressure here if charging with a gauge set. Not necessary if just adding freon – add freon 134A till low side reads around 45psi
