What was the rpm at which you got those readings? Plz provide readings at 1800 rpm.
Why was work done to the system?
225 psi at 75F is a bit high and doesn't leave much leeway when the ambient gets to 95

As you stated usually at the r/d.
It is not clear why you need a second switch.
Any pressure change at one certain point in the system will be felt almost immediately by the entire system. IMO the one sw is sufficient

At what engine rpm did you get your gauge readings? Idle or 1800? S/b at 1800.
John’s questions are very relevant, sounds overcharged from here.
What was the reason for re-charging the system

Allow 1.0 fl oz for the condenser>

Yes, unfortunately. The comp grenaded and took out everything downstream as he described. Please remember that a condenser cannot be flushed

Tim, just to be transparent, due to surgery, I am off this board for a while\
Thanks, Texas Dave

Get a professional Manifold Gauge Set as mentioned by JohnHere and post both hi and low pressures, and ambient, and center vent temp (digital thermometer is best), with engine at 1500-1800, max fan, max cool, recirculate, doors and windows closed. With that info we can tell you the health of the sys...

Nonetheless, leak seal should be avoided, it is suicide.....marketing!!!!
All the pros here will advise against it

We NEVER advise leak sealant, see your other thread ...it will gum up your system

You did not step on any toes. We are here to help. We are in the USA so we limit most of our advice to EPA approved refrigerants, but as JohnHere stated you are still welcome to ask questions. On another note, we always advise owners to never use any kind of sealer, EVER. It is guaranteed to cause h...
