my ac compressor is on the way, its the whole kit the orfice tube and accumulater and compressor. I havnt had ac in almost 3yrs in the blazer. do you think i need to get it flushed still. the compressor never locked up it just couldnt hold freeon. and since theres no freeon i dont see a point to having it evacuated but just charged when the install is done. I know there is a post on how to install it and stuff on here but im more of a seeing and learning guy more than reading and learning. so if anyone is got tips and pics thatd be cool. I just dont want to spend money on gettting flushed if it isnt needed. could i use this to flush it myself http://www.oreillyauto.com/site/c/de...1785&ppt=C0050

 

If you don't evacuate the system how will you get a moisture & get the air that gets in when you open the system? Air+Moisture=no cooling.
I can assure you, you will void any warranty from any manufacture.
You better have someone that is a licensed A/C Tech do the job RIGHT.

 

ok that answer one question now what about flushing the system does it need to be done. if so what all would be flushed. im replacing the accumulator and compressor so im taking just the linesl. but like i said the ac hasnt been ran in almost 3 years

 

That flush should be ok if your system has been sealed, but I would HIGHLY recommend pulling a vacuum on your system before you recharge. You need to get the air/moisture out of the system before you charge it. Freon + moisture = bad mojo.
