Compressor, outdoor fan Pipe Insulation - Arizona

Hello, on my last two homes in Arizona, at the point where the copper lines ran through the exterior wall, there was a black, flexible tar like substance used to insulate where the pipe ran through stucco. When I had that house re-stucco-ed, they redid the insulation with more of that black tar.

Does anyone know what that substance was. I need to buy more for another house in Arizona.

Thanks!

It is black insulating tape. HVAC supply houses carry it. It would be easier to get 3/4" pipe insulation.

And use the playdough like stuff to seal the penetration in the ext wall. Can't ever remember the name but they carry it in both electrical and the ventilation aisles.

No, its the not tape. The pipes are indeed wrapped in black tape, but in Arizona, there is also a black tar used. I saw the guy put in on my last house when he redid the stucco.

It sounds like you are talking about cork insulating tape.

It feels like tar and cork.

Aesthetically Pleasing Venting Options for Portable AC

C

cdcd33 on Jul 07, 2014

I'm considering adding a split AC to my home, but was soft quoted $6K-$8K over the phone for a 2-zone system. That's a couple thousand more than what I had hoped to spend. So, much to my chagrin, I think I need to consider a portable AC. First room to tackle is the master bedroom - 200 sq ft with a big 70"W x 60"H window that opens right to left. Most of the venting options I've seen are for much smaller, up/down windows. Any thoughts on what I do to make this fit in a somewhat aesthetically pleasing way? And besides venting through the window, are they any other venting options or kits that I should check out?Read More

I have a heat pump for heat and cooling. The fan was on. Then it wasn't. Then it came on again. Now it won't come on at all. Duct work is all attached. Thermostat clicks, but no air. Please help. I'm a single lady with little money.Read More
