Please help with vent hood placement. Which option is better? Duct going to the side for a run of 9 feet with 2 turns or putting it in on a different wall where the duct will go down to basement and out next to patio door for a run of 30 feet. It is a 2 story house with a bedroom on top of kitchen. Is it still possible to go up the roof? I am thinking of putting a 36 or 48 inch hood depending on cooktop I get. What type of hood would you recommend? I do lots of frying and Indian cooking with spices and need good ventilation.
