If the car has been sitting for awhile maybe the heater fan has a mouse nest in it. Not much info to go by . Does it get louder when fan gets turned to hi ? Could it be a hissing sound from one of the vacuum hoses being off ? Does it change at all when climate control unit is turned off? Message me and I can try to help you further.

good points, but there is no vacuum on the climate controls, just electronic servos. If you do hear a vacuum leak, the only source i know would be the parking brake line.
