In CA, the seller would have to disclose what you are trying to hide.

I need to keep it for the time being since I stay there while I work and it is needed with the bad heat upstairs in warm weather. Sorry, I meant that i am trying to make it look more presentable not that it is unsafe. (It has been used for years.) It was all professionally installed just could use some cosmetic touches with the awkward wires draped across part of 1 wall.

Ask your real estate agent. This sounds like a through-the-walk unit. My bet is an inspector will flag an a/c unit that old. Maybe get a quote on an efficient modern unit with outlet adjacent to the unit.

That is one old AC I would remove it patch the wall and the exterior wall and let the next guy figure out AC since there are so many new choices.

A large AC should not be using an extension cord. I suggest getting an electrician give you a quote to move the outlet as close to the AC unit as possible. If the AC works and keeps the house cool then there is no need to remove it.

Okay thank you, I will definitely look in to that.

There are several reasons you might wish to hide the cord for your vertical air conditioner. You may have a young child who takes great delight in chewing on electrical cables, the cord may present a tripping hazard or it is just plain ugly.

1. Simple Cover Up

The easiest way to hide a cord is to put it behind already existing furniture. If you have many cords in the same area, tape them together, making one strand. It is possible to hide the cord under a rug, but this can create a fire hazard.

If you merely wish to shorten the cord for your air conditioner, purchase a cord shortener. This device will roll the cord into a contained unit. This unit can then be near the outlet. This outlet can be easily hidden by a piece of furniture.

A PVC runway is an easy way to hide your cords. The PVC runway is placed over cables that run along the wall. It comes in many colors. If a color doesn’t suit your needs, simply buy a paint that matches the color in the room. Be sure to buy a runway that will fit the size of the cords you wish to hide. The easiest type of PVC to install has an adhesive back.

Yep, get the PVC runway.
