I never really gave too much thought for where the air in my vent hood ends up. Heck, half the time I was reluctant to believe the air went anywhere at all. I used to wonder if I took the vent panel off ceiling above the stove, if I would even find ductwork or just a wall looking back at me. But as I found out the hard way one winter morning, the vent hood in my kitchen does indeed work. In fact, it does more work than I had realized. A few weeks ago, my new roommate moved in and has been trying to learn to cook for her new boyfriend. Well, her first few attempts have not gone well. It smelled so bad I had to open the door to the patio for a few minutes before the snow started coming down. After that, we left the vent hood on over night, hoping it would clear the smell out by morning. Well, when I woke up the kitchen was freezing! I thought the door hadn’t been shut all the well, but that wasn’t it. It was freezing around the stove, and the poor electric heater was constantly cycling. I had completely forgotten that leaving the vent hood not only removes smells, it takes out the hot air! I had to turn it off and advise my roommate to only run the vent hood for 20 minutes. Otherwise, we’ll be looking at one hell of a utility bill.
