It has too much 134 a in the system. Too much will give you the same result as not enough. You need to let some of the pressure out of the system. When you get it back to the normal level you will want to take it to a service center to have the expansion valve checked or replaced. They will be able to vacuum the system down and take care of it within a day or less.

2002 f350 v10 ac blows warm. Tried a recharge kit and shows pressure in red(high). Released pressure. Worked great for 2 days and now it's doing the same thing. Pressure in red blowing warm


May be a plugged drier causing too much pressure on the high side.
what is /was the low side pressure? If in vacuum, that would be a confirmation of the cause.

2009 chevy AVEO 5 ac blows hot air


The guage needs to read between 35/40 psi.. If its much higher you may be overfull, this causes it to not cool.. Fix by letting some freon out, then top it back to needed pressure.. If pressure is correct, it would be a clog in the system.. Usually an orafice tube or accumulator..good luck!

Air conditioning


It sounds like you over charged the system, the low side should be 40psi to 50psi with the A/C on high and the high pressure side should read 150psi to 200psi. Anything different, you need to get the system service and try not to use your A/C to prevent the compressor from any damages. Good luck and hope this helps.

AC has stopped blowing cold air. Compressor is working. Where is the recharge valve located?


There are two A/C refrigerant lines. The small line is your high pressure line and the larger line is your low pressure line.
Start at the fire wall and follow the "large " low pressure line to the compressor. The low pressure charge port will be some where on that line.
DO NOT try to recharge on the high pressure side ( small line )
Good luck, let me know.

My 02 trailblazers air conditioner blows real cold air but sometimes it won't blow out cold after i turn the truck off and start it back up . after i drive for a while it starts blowing cold again the...


when an AC gets real hot and there is air in the system you get what is called High Head Pressure and the high pressure switch will not let the clutch engage. Need to have the system evacuated and recharged.

My ac not working


Your A/C will not work with to high of pressure. You will need to relieve some. There are easy ways that I’m not willing to put into writing. Then check the pressure while running.
