Does it go away after a minute?

Some whooshing noises are normal as the A/C system is first engaged and refrigerant changes pressure.

no, only after AC is off the whooshing noises disappear gradually, if AC on ,there are always whooshing noises. A/C used to be quiet in the past.

Might be a bad expansion valve. My 2012 had one replaced under warranty.

A set of gauges on high/low sides will be needed to confirm.
