The old exhaust fan over my kitchen stove stopped working completely last month, so I finally ordered a basic stainless steel range hood to replace it. The retail box made it seem like a quick job where you just screw a metal box to the upper cabinet, plug it in, and turn on the fan. What a complete joke. Trying to hold a heavy, sharp metal appliance perfectly level while reaching inside the casing to drive mounting screws into solid wood is a total balancing act when you don’t have a second pair of hands.
The biggest headache was getting the old unit out of the cabinet alcove. The previous installer had apparently used about an entire tube of heavy industrial construction adhesive along the back wall, so the metal casing was practically welded to the plaster. I spent nearly an hour wedging a flat crowbar behind the sheet metal and hammering the handle just to pry the old frame loose, which ended up gouging a huge scratch into the side of the cabinet molding. When it finally snapped free, a massive pile of oily, yellow grease chunks dropped straight down onto my clean stovetop.
Once the area was cleared, trying to route the flexible aluminum duct pipe through the upper cabinet shelf caused the real breakdown. The hole cut into the wood was about half an inch too narrow for the new vent collar, so the flexible duct kept crumpling up and tearing like aluminum foil every time I tried to force it through. I had to stop everything, hunt down a wood file, and manually grind down the interior edges of the cabinet cutout until my wrists were totally stiff just to get the pipe to slide into place properly.
The range hood is finally securely mounted to the wall framing now and the electrical connections are fully taped up inside the junction box. The fan settings run smoothly and the overhead LED lights are bright enough to light up the whole counter area. The ventilation system clears out the steam perfectly when the burners are on, so the unit is fully functional for cooking now.
