Musty odor coming from ac vents

I replaced ac compressor, cleaned hoses, new dryer, new o-rings and new expansion valve and now I have cold air coming from vents but now I also have a musty odor coming from vents. I need help getting rid of this smell. Thanks

You may have a problem at the bottom of the Evap box - not draining.

What is the year of your 911?

I agree, you will need to verify that the drain hole is not plugged.
This is done by checking for water under the car after A/C use.

On occasions, the drain may be only partially plugged, which may cause some confusion.

To clear the drain hole, use a very flexible item as to not damage the evaporator.

The drain hole is slightly visible at the resistor pack located on the passenger's side floorboard.

Also, if the compressor does not have the proper on/off cycling time, the evaporator will freeze up and produce the issue you have detected.

Good luck,

Gerry

You may pm me.

there's a fungus among us

besides the above, you will want to clean all the duct work with a bleach solution - use a push/pull rod with a swab you dip into 1/4 bleach with some detergent in water

this can be very important for the health of those riding in the car - it can be a medical issue, not merely an obnoxious odor

Wurth makes an A/C mold killer spray that is very effective. Mold tends to grow on your evaporator. You spray this into your return ducting while ac is running then let sit for a few hours. This of course after making sure your drains are clear.
