Is there such a thing as a slow freon leak that may delay freon depletion?l???

if you have a tiny leak, i suspect the freon will completely vacate the system fairly quickly

and leaking will continue even if system is not being run

Most coolant leaks are small and slow. The coolant is rarely depleted before performance drops and maintenance is done. Why do you ask?

slow freon leak?

if there is a freon leak, how long will it take all the freon to leak out.

if you have a teenytiny leak in a balloon it will not retain air.

Not my area of expertise but I would think the pressure would be greater while the unit is running = more apt to leak or leak faster than when idle. A fast leak would be one you could hear, a small leak could take a good while [months] before the freon would be low enough to cause problems.

It can be from 1 day to many years depends on how small/slow the leak is. some leak only occurs while the system is running due to high pressure.

It's possible to have a very slow leak.

---------------------------------------
Refrigerant is not "coolant" and "freon" is just a brand name.

When the leak is on the high side (downstream of the compressor but upstream of the indoor coil), operation increases leakage.

When the leak is on the low side (indoor coil and larger, insulated line leading to compressor), operating reduces leakage.

Yes, freon leaks can be extremely small. Since copper expands when it gets cold, the evaporator coil will usually only leak when the system is running. Though you can have a leak that is even smaller than that. Those micro leaks can be caused by a nail going into the freon lines. the nail will hold the leak, mostly, releasing one bubble every few minutess or hours. but that only happens during constuction or siding repair on a house.

Right. I somehow got a/c refrigerant confused with the stuff I pour into the radiator in the car! Point taken!

do a visual on al the lines accessable and grab the insulation looking for oil residue...when freon leaks out so goes the oil droplets that rip around the system.if you went thru a winter and had just a fart on the shradder pins that is considered an OFF leak.how often has it been filled up over the years there.if you find an oil wetness any where or wet dust dirt out on that condenser might be a leak.
