Poor AC output with a full ac system

[YellowAztekinNEOhio]

I have a gage and it is in the green good low pressure side. But the fan is blowing out mediocre cool air . I can’t find anything yet as to a reason ,

Does the output line from the compressor, high side, get very cold, you might even see frost if the humidity is high, as it goes into the evaporator core?

 

[YellowAztekinNEOhio]

I got to find it and test it per your advice. evaporations core is inside one , Small line

No the small high side line does not get cold!

You have narrowed down the problem to an AC issue as opposed to a blend door issue.

 

[melsg5]

You mentioned only low side, do you have a set of real gages or is this part of an auto parts store recharge kit?

 

[YellowAztekinNEOhio]

Yes

 

[melsg5]

So what are the high and low side reading with the compressor running?

I found high pressure port at an easy access spot under the cruze control module . Here’s what I got
, I too photos of the hot set up for you to see . I get 30 low side and 50 high side

High side is low, have you tried adding refrigerant?

Are you watching the gage high pressure?
The link I gave you stated air temperature doubled + 50. So on a 70 degree day you should read 190 high.

The refill was an auto parts single gage , I did use the gages I had I was thinking , what don’t measure you don’t control.

 

[melsg5]

Buy some cans of r134 and use your good gage set

 

[YellowAztekinNEOhio]

filled it with the can I bought cause wanted to use it up. It not the best way, cause you fill but can’t see high side .
I almost over filled it ,maybe i did.
got 40 on the low side and 240 on the high ,
it putting out cold enough air for me to say it’s working pretty good .
thank you so much for coaching me though the steps

The low side large pipe gets cold but the smaller high is hot

 

[YellowAztekinNEOhio]

Today it 73 degrees outside temp ,did I overfill it .

 

[melsg5]

So you didnt use your gauge set with a can of r134, you used the quickie charge can from the auto store.
I would say 240 on a 73 degree day is on the high side.

Retested it I got 35 low side ,and I got 200 on high side. I had troubles getting the high to connect do to hard to access , had released some Cause reading are close to spec ,and it still cold out, I’m finish with it thanks again
