Good day, Mr. Dubois...

From your brief but precise description, I would say that your intake valve is failing, or has debris lodged in it, preventing it from closing when the compressor is trying to pump air into the tank.

Instead, the compressor is huffing and puffing. Not very efficient, and, in time, your compressor will build little, if any, pressure in the tank at all.

Needs to be fixed, sooner than later.

Cheers,

Bill
