I want to remove a heating duct. How can I seal off the opening from the furnace/a.c.? I'm concerned that whatever I use to close it off may just get hotter and hotter when the furnace is on, eventually causing a fire.

put a cover over it, sheet metal screw it in. A piece of galvanize bigger than the duct and screw her in.

Okay, that sounds reasonable. Thanks.

But I have to admit, it feels a little strange to be taking advice from a dog.

Back where I come from, there are lots of gangsta gorillas. I'm not at all unusual.

Mission accomplished, and it went just like you said. I cut a piece of galvanized to cover the hole, popped in four screws, and duct-taped the whole thing because ductape is righteous stuff.

If anybody ever gives you any crap about being a dog, you let me know.

Most systems have a damper on each duct that you could have closed unless you need the duct removed for more space. I would recommend using aluminum foil tape.

No dampers. Just like none of the plumbing fixtures have shut-offs. Cheap-ass people. If you want to hate someone, buy a house from them.

You should see the wiring. I've pulled out hundreds of feet of useless junk, and I still have a ways to go. I've got water lines supported by electric lines. I had live wires dangling down loose in the basement.

I'll check out the foil tape. Thanks.

If the system is in the basement and you want a little heat down there then a little leakage around the cover should be ok. It may keep the water pipes from freezing on those very cold days.

Hope you got a bargain on the home if it needs work.

Yes! I got about a 15% reduction from the asking price. I am very pleased. Even with having to do some work, it's a good deal.
