When the compressor is on, I can hear a leak from where the motor is located. Hissing is extremely loud. Sounds like a small leak. At this point, I am losing a little pressure, but am still able to use the unit. I am reticent to continue to use the unit until repairs are made. Please advise as to how or where to take the unit for servicing.
