Cheap quiet air conditioning

Does the unit double as a sump pump if it rains?:rofl:

Just kidding! I wish I had a crawl space like that- to put my blazing hot electronics! Wow, that graph is too cool: pun intended :dumbcrazy:

The graph says it all. :T

Yeah, nice work there.

Great idea and execution. :T

Better keep your eye on the duct tape, though - it won't hold up long. I believe there is some kind of tape that AC guys use that's more substantial; I've seen it in attics on central AC units, looks shiney like chrome. Not sure where to get it, but I'm sure it's available at an AC supply company.

Home Depot sells it too (A/C section). I believe it's called foil tape. It's metal and adhesive. It sticks to ANYTHING!!! Just wrap it around like you would duct tape and then use a credit card or plastic scraper to smooth it out.

I need to rig a floorstanding unit in my attic like this. Nice work

The foil tape is requirement on HVAC ducting that carries heat. I don't think it's a requirement on cool air only. The reason being that HVAC vents can get hot and duct tape will melt. The misnomer that duct tape is for ducts is just that, a misnomer. Duct tape is just reinforced general purpose tape.

The foil tape is a little stickier but won't apply well to plastic. One thing that can also happen with the duct tape is that the glue will dry up and the plastic will deteriorate over time. It will basically fall of. The glue will dry up on foil tape (after a long time though) but it should still hold it's form if applied correctly.

It's also a big no no to run extension cord like you have it. I would also strap the speaker wire (gold colored wire in your picture) up off the ground.

Also where is the condensation from the AC going to drain to?

Place it on top of an old car tire and make sure that you have adequate attic ventilation and a drain system .

Alluminum tape is what the AC installers use, i got my 2'' roll for 8 bucks and the stuff is super sticky should be able to pick it up at the home store no problem as that is what it's made for. As the name duct tape implies it's gennerally not a good long term solution as it will come apart over time.

By the way good idea for keeping things cool quietly.:T

Looks like i should have read the rest of the posts everyone already made a reply as to what kind of tape to use, my bad.

Holy smokes. Looked like a sealed crawl space in the first image.

I too am Canadian, but I live in balmy Southern Ontario.

I would cover the bottom with Tyvek after adding another layer of foam board and then something more durable/less flammable to cover it. Soffit material would be best but you could use siding or cedar planks or pressure treated planks. That will stop animals from chewing it up and making nests in it and ruining all of your hard work.

You might also want to build some removable insulation plugs that you can stick down the register vents leading to the AC unit for winterizing the place. A cover or tarp also for the unit so it doesn't rust out in a year.
