So - full disclosure... I am not a professional installer, I'm just your average Joe trying to replace my old WhisperKool AC unit with a new one AND had to swap out the ducting kit to do it. First off - The people at Wine Coolers Empire - Totally top notch and helpful. Any difficulties I'm encountering are not on them. Second, the kit that came in is big - larger than the space I'm venting to. Yes, I understand that it bends and that you can adjust it, but because it has the added fan unit in the ducting kit, it adds a good foot to 18 inches to the length of the duct. Where it's located in the unit is NOT adjustable, so you have to have a good space behind the unit to make it fit. I don't, so I had to MacGyver the hell out of it. Also, the unit attaches differently than the old unit which adds even more length to the ducting. I had to change this entirely, chisel out 1/2 from the side 2x4s so I could make the new housing work by attaching it to the unit on the room side - not the back space side. Ultimately, I had to pay $579 for the kit - really all I needed was the 1 piece that attaches to the cooler, I didn't need all the rest of the ducting, I already had it. Overall it was a triumph of ingenuity! Did I mention I had to work on this thing 3 weekends in a row to make it work? My brain hurts from having to think so much. Hopefully I'll be dead before I have to replace the next one.
