I’ll start by mentioning, I know that if I have to recharge the ac system with Freon, I know I have a leak, I know I should have a ac tech diagnose it, I know it’ll eventually leak out and I also know that stopleak could damage components of my ac system which could cost me more money to repair than if I had taken my car to an ac tech to have it diagnosed properly. Ok with that out of the way... the past 3 weeks, my ac hasn’t been as cold... cold but not as cold as it used to be. Also the compressor would click on and off every 1-2 seconds everyonce in a while depending on conditions (ex:stop and go traffic in 90+ degree weather or when accelerating aggressively and sometimes click off for minutes at a time before it decides to click back on.) I decided on buying a recharge kit (big can of r134 with hose and pressure gauge). I got the engine to operating temperature and turned the AC to full blast. Compressor is spinning and staying engaged with no issues previously mentioned. Hooked up the recharge kit to the low pressure line and with ambient temps at 75 degrees at the time, low pressure line shows 25-26 psi. I use this chart I found here: 70f 25-45 psig 80f 30-50 psig 90f 35-55 psig So I’m shooting for 37 psi, I start filling her up and immediately the lines get ice cold and colder air is coming out the vents and I proceed to get a mechanical hard-on. Once half the can is sucked into the lines, the gauge reads 30 psi, I’m shooting for 7 more psi so I continue to charge with 4 second bursts every 15 seconds... now the can is nearly empty and I’ve only achieved 1 more psi so I’m at 31 psi and I empty the rest of the can into the system and still... 31 psi. I drive for an hour and AC is ice cold during idle but isn’t as cold during acceleration, ac clutch isn’t disengaging like before so that’s good and the vents got so cold that condensation formed around the vent bezels. Cut to this morning, ac still cold but drove for an hour and Ac loses its cool slightly acouple times for a minute during idle and during acceleration... My question, Does that mean I could need another Can of r134?
