I recently bought a Kenmore range hood that CR recommended. For all I know, it may be a great hood, but to find out, I'd have to be able to install it.
The Sears website says the the hood comes with a non-ducted installation kit. That kit does not include what the manual describes as a "5' flexible metal duct."
Home Depot stocks 4" and 6" ducts. So does my local plumbing supply store. Sears doesn't sell them at all. In fact, the part that the duct needs to be connected to measures 4 1/2" so I don't know where they're getting the 5" measurement from.
I called Sears customer service and a kid at the call center suggested I make up the difference with duct tape.
I called Sears corporate offices and was told I'd be connected to the "executive" something-or-other. It was another version of customer service.
The first person there wouldn't let me finish a sentence while I was trying to explain. When I pointed that out, she hung up on me.
I called back and said I'd like to speak to an actual executive. I was told Sears executives won't speak to customers.
I was connected to the executive thing again. The woman there transferred me to the installers as the store where I bought the hood, who transferred me to the parts department, where I was told they didn't have the part, which I already knew.
A half dozen phone calles, and hour and a half of my time, and a range hood sitting in pieces on the floor of my kitchen.
And absolutely no help from Sears
