A/C Issue

[NJ04HOE]

I noticed since the temps started to go up around here lately (90's-100) that my a/c isn't as cold as it was every other summer before now. So I went and bought a recharge kit and I figured that would be it, but no it's still just cool and not like it was before freezing cold.
I also checked to make sure the compressor is kicking on and it is....

Anyone have any ideas on what else could be the problem?
Thanks

what pressure is your lines at? if it's too high it will have a negative impact.

How do I find out the pressure?

exact same problem I had last week. I bought a recharge kit with a gauge. Released the 134a......same thing, still not as cold as before. Gauge reads 50 psi on the low side. When I start the AC, I hear a growling sound from the dryer. It will get cold maybe after 10 mins of driving.

So I brought it to a shop. Low side reads 60 psi, which is too high. Normal range should be 30 - 40 psi. The shop vacuumed the freon out.......ALL 4 lbs OF IT!!!!! Again, it should normally be 2.7 lbs. In other words, I overcharged it !!!!

Freon was pumped back in and now my AC is as cold as ice.

I completely forgot I started this thread.....
That's exactly what happened to me, I took it to a shop and it was overcharged. Now it's fine

Test it at the port.

Here are the charts for pressure, relative to air temp and humidity, for the low and high side.

First chart is with rear AC, second is for non-rear AC.
