Ductwork right above the stove was dumb

The placement of my ductwork is so stupid. Whatever HVAC contractor set up it up obviously was not a chef. I have an air vent opening right above my stove. If I put anything on the stove burners, steam rising up and goes into the air vent. The smells then waft all through the ductwork and every room in the house smells like what I am cooking. It would be okay for like an hour. But, the cooking smell lingers in our indoor air quality for hours. Smelling roast beef, pasta or fish for hours afterward is super gross. Another issue is the grease and condensation from the steam. These both get into the air vent and stick in there. Frequently I have to clean out the front of the air vent since there is mold all over it. Then I have to take the front off and do my own form of ductwork cleaning. The grease makes it so sticky and gross in there. I don’t want the heating and cooling system to turn on and that gross stuff to be in my air quality. What can I do about ductwork placement though? I can’t move the stove and I can’t move the ductwork. I just use my burners sparingly and clean the ductwork any chance I get. I hate it though. It makes cooking not fun anymore and always involves a ton of work afterwards. What HVAC contractor did not think about the stove burners when doing the installation? When the AC is on, that hot steam makes so much water that it literally drips on me.
