09 pontiac vibe 2.4L ac problems

Hey Paul im having and issue with my air conditioning on my 09 pontiac vibe 2.4l engine, when i first start the car, i get in and start driving the ac blows ice cold but roughly 10 mins later it will start blowing warmer air, Compressor runs constantly and everything, i get the rpm change when i turn the ac on. I can smell the change from cold to heat when it starts blowing warmer air, would u have any advice on what to look for or check paul? If u can that would be great. On a hot day i can start the car and as long as the fans stay constantly running it has cold ac but after about 10mins my fans will start clicking on and off for a few seconds (constantly) thats when it starts blowing warmer air. Any advice would be great i will post my pressures when it starts to blow warmer air, as soon as i can. Btw the (Compressor is controlled electronicly), its not a clutch cycling compressor

You have moisture in your a.c. system and it's freezing causing a restriction....

I just took a reading its roughly 90 degrees here and about 70+ perceny humidity my rest pressure was 110psi and my running pressure was 35psi on low side and around 220 230 on the high side i ran it for about 10 15mins and it blew nice cold air it never messed up on me so now i dint know whats going on. Yeah i thought the same thing but im not sure what my pressures mean as far as if and what is wrong. I did notice the compressor just ran it didnt cycle tje guages up and down or anything but it blew nice and cold... Weird man any advice would be great thanks for responding ben
