A/C how to make it cooler?

[Custom Sills]

Bros I got a 4.6 2V and my A/C was not working. The condenser had a hole which we fixed by welding and some orings had to be changed. Now the A/C is thight. We filled it with 700 gram (24.6oz) R134 refrigerant.
It cools but in my opinion not enough!
I added two 11" fans to the condenser but these made no changes to the cooling capacity.

My question is, which components of the A/C can cause not enough cooling? For example the accumulator, should this be serviced or changed? Any other suggestions?

Is R134 700 gram (24.6oz) enough?

Did you pull a vacuum on the system before adding in the refrigerant?

It was filled by an a/c shop with a professional machine. It made the vacuum before adding R134

Which exact engine and year is your?

My 96 Cobra with probably the same compressor as yours takes 960g, with about 3-4 oz of that being PAG oil.

If it wasn’t done, the accumulator and oriface tube should’ve been replaced as well. If not, there could be moisture in the system affecting its ability to cool. Buy a set of manifold gauges and a thermometer and we can help you do it yourself.

Yep, all A/C systems work to dehumidify. There are desiccants in the system. At minimum, pretty much the entire system should be replaced every 10 - 15 years just depending on how well it was maintained. And maintaining is easy: you need to have the A/C system running at least a few times a year for 30m each, even in the winter, so that the PAG oil can circulate and keep all o-rings lubricated. Once those o-rings dry up, they degrade excessively and invite air/moisture inside. Once this happens, the desiccants get too saturated with moisture and they too get excessive degradation.

The first thing I would do is check the temp. at the center vent, on recirculate, windows closed, and high idle. It should be around 50°F on a warm day. If not, check the simple stuff first, such as a blocked or dirty condenser. Also make sure the temperature door is working properly.
