Swamp Cooler Damper

Hello,

My swamp cooler shares the duct work for my furnace. I was wondering if anyone had any suggestions on how to seal it off at the roof so that hot air is not escaping. I would like to install some kinda of damper and then cover the unit as well. I am looking for an inexpensive solution that will just cover the duct opening. The cooler doesn't work too well and I will probably replace it next year anyway.

Thanks,
Bryan

Would something like this be safe to use to stop the hot air form the furnace from escaping?

The duct has no slot for a slide in damper.

First I live in MA. so we don't use Swamp or Evaporative Cooling here so I haven't done any work on one, but I see no reason why you couldn't block the air intake from the outside with a piece of plywood or something. As long as you can get inside the unit, if there isn't enough room you may have to cut the wood into two pieces and secure it so the air from the furnace won't move them. I can't believe there isn't a damper someplace, I'd look a little further for one, How do you usually block it? Make sure the Disconnect is off.

I haven't had to secure it before, my wife and I bought the house this summer. I have looked and looked, even looked in the attic, no damper to be found.

Unfortunately, I had somewhat forgotten what the inside of the unit looked like since servicing it a couple months ago, it would be impossible to cover the duct without removing the squirrel cage. The previous owner had some sort of tarp covering the thing. Well really it was like 3 ripped up sections of a tarp wrapped around the thing and held on with bailing wire.

Not sure what to do about the situation, maybe I will just get a good cover for it and make sure it is secured well. Seems it will still lose a lot of heat.

If your mechanically inclined and going to be replacing the unit next year why don't you make up your own damper? You may have to separate the trunk in order to put in tracks for the Damper and cut a slot to receive it. It'll take a bit but it's something you have to do anyway and not really that hard, just a little time consuming. Good Luck!!! :)
