Your question: Can a car AC be low on freon without a leak?

The simple answer is No. There may be something wrong with the system that may seem like it is low like restricted metering devise, suction or liquid line but if refrigerant was added and now the unit works properly then there most likely a leak assuming the unit was properly charged when manufactured or installed.

Can a car lose Freon without a leak?

While a fully operational AC unit should not lose any Freon, a typical unit that requires servicing and maintenance can, even without a visible sign of a leak.

What causes low Freon in AC car?

AC systems operate using two different sides, the high side and the low side. … Over time, these pressurized systems can eventually develop leaks. Once any sort of leak has begun, they will eventually cause enough refrigerant to leak out to the point where the AC will no longer be able to produce cold air.

How often should you recharge freon in car?
