[Calisport]

I just moved here to a new construction villa. The microwave exhaust does not exhaust to the outside I found out. It blows upward from the front of the microwave to the ceiling. I asked a designer home owner and their kitchen exhausts to the outside. I am in a patio villa. Did the builder decide not to vent the smaller homes, and what can I do to fix it? I have a walk through in a week. Thanks.
