Those cans add to low pressure side
Ah, tells you what I know about that stuff. What should the pressure be then?Those cans add to low pressure side
Well, that's were I have it. Thanks.View attachment 1805592I like to use this for reference. The low and high side pressure depend on ambient temps.
Turning on and off.I think you may have some air in the system, the low side is a little high but you should have cool air coming from the vents. Is the compressor short cycling?
If it’s doing it quickly on and off then it’s low on refrigerant and/or has air in the system. Only other cause if this is a failing compressor clutch relay. The contacts could be getting weak and causing the compressor clutch to cycle to fast. But my money is on low charge.Turning on and off.
Add more then? I don't want to overcharge it. How would one get rid of the air? This thing sits a ton.If it’s doing it quickly on and off then it’s low on refrigerant and/or has air in the system.

I would evacuate it all and pull a 45 minute vacuum and then install the correct amount of refrigerant. You can buy a set of gauges and a vacuum pump from harbor freight. The other option, if you know a trustworthy shop is to just have them do it for you and then see if they can do a leak check. Usually the valve cores leak, quick and easy repair.Add more then?

I didn’t know that the auto store will allow people to use the gauges and vacuum pump. I think it is funny how anyone can go to the store and buy cans of refrigerant but I have to have a license to legally perform A/C work.i rented both the vacuum pump and the set of manifold gauges from auto zone/oreilly when i did my f150. it cost me nothing for the tools, but i did buy the 3 cans of r-134 and 1 bottle of pag oil from them.
i knew nothing about ac before that. but that was two summers ago and it's still blowing cold. i did have a shop recover the old freon though, i dont think you just open it to the atmosphere... or maybe you can?
it was actually the shop i brought it to to have the system recharged. of course they tried to upsell me - telling me i had a leak and needed parts. i was like just suck it down man, i know there's no leak... but they even charged me $65 for that
The local speed shop doing repairs on my wife's Fusion Sport gave me the break down on repairs. I was floored when I saw $500 for AC refrigerant capture/fill. It cost $7500 to pull the engine, do a complete valve job.....for Pete's sake.That seemed fine Paul. Still had little in it.
Crap like this makes me want to get rid of it. Boss won't let me, yet.

You should never just let the refrigerant out, big no no. I would just take it somewhere for them to recover the refrigerant.
If you were low and needed 3 cans of refrigerant, you have a leak. They were just doing there job trying to make some $ and help you find a leak by the sound of it.
