What do I do if my air conditioner is low on freon?
If you suspect that your Freon is low, it is always best to call a trusted HVAC specialist like Autumn Air to come out and troubleshoot your AC. If there is a leak, they will be able to fix it and have the correct tools to do that as well as refill the Freon in your unit.
What should the pressure be with the a / C off?
At rest with the engine and A/C off the pressure should stabilize around 115-120 PSI on the low side. I also agree with the others that you might consider getting an A/C shop to look at this as A/C work can be a bit dangerous on top of causing even more damage to the system.
How to know if your a / C system is low?
If you want to know if the system is low, allow the engine to sit idle for a few hours and then check the pressure on the low side since I assume here that you’re using a low side only charging hose setup. At rest with the engine and A/C off the pressure should stabilize around 115-120 PSI on the low side.
What to do if your a / C pressure fluctuates?
Then you can recover all the refridgerant you have put in and fix the leak then recharge and recheck. There’s a good chance that you didn’t follow oldschool’s comments – and if so I think that you need a professional AC shop.
What’s the pressure on the a / C charger?
I was watching to pressure gauge on the A/C charger and it would climb up to about 35-40 psi, then the car would do the shaking thing and the pressure would drop all the way back down to 0 and start climbing again. Anyone have any idea what the might be?
