Live in an 11th story condo, HOA has strict policy against cutting new holes into outside of the building. I currently have a dryer vent with fairly easy access to where i would like to put the vented range hood. I know it is a very bad idea for them to share same pipe. But would it be bad for them to maybe come together behind wall where they exit? I do have access to the dryer vent on exterior of building via a balcony. Anyone have another idea? I am desperately trying to avoid a recirculating range hood. Thank you in advance for the help. Please ask any questions, I will check thread often tonight.
