Unused wall outlet getting slightly warm

I have a wall outlet in my bedroom that gets warm(not hot) even when nothing is plugged into it. My desktop computer is setup to the outlet 8 feet to the left of it, and my room ac(5000 btu) is plugged into the other side of the room. Both of these are plugged into completely different outlets. I smell no odor of any kind coming from the warm outlet. And it doesnt stay warm all the time. Should I be concerned?

Any tips here would be greatly appreciated.

Yes, you should be concerned. Do you have aluminum wiring? Even if copper connections need to be redone. and if backstabbed nnmoved to the screws. If though aluminum even more work will be needed.

Any load downstream of a loose connection will cause heat to build up. Too much heat can lead.to a fire.

yeah I'll have it looked at asap. Oddly it only seems to get warm when I run my window ac unit in the same room. This ac unit is on the other side of the room plugged into an entirely different outlet.

Different receptacle or different circuit?

The heavy.compressor load.is.going thru the receptacles upstream where you are seeing the heat.

What I would start off with to investigate...

Go to panel and turn off that socket.
Let's see if the other one really is on the same circuit or not.
Also, this lets you see what else may be tied onto that circuit with some more investigation.

If it's a fuse-box, what does the amp rating on the fuse say? I would not be surprised if some lazy person used a 20+, and the wires are only rated for 15.

A loose connection at that warm outlet (receptacle unit) which is in the daisy chain over to the outlet where the air conditioner is plugged in..

Loose connections can get hot even when far fewer amperes than the breaker rating are being drawn..

I suspect your window a/c unit and PC/monitor/printer/etc are on the same circuit and drawing too much current for the wiring.

Do you have aluminum wiring?
I am still interested in the answer to this question. When was the house built? Loose connections will get warm whether copper or aluminum wire, buy if you do have aluminum wire you probably have more issues than just the one warm receptacle.

BTU is a non-metric unit that doesn't tell us much of anything here.

What is the Watts rating on the unit? It should be labeled somewhere. If not, how many Amps does it draw, and we can calculate from there...
