How to Use a Remote Control for an Air Conditioner. Getting up from your seat constantly to change the temperature on a portable or window air conditioner can really be a drag. It's reminiscent of the days before remotes, when you had to get up from the sofa to change the channel on the television. That's practically unthinkable now, so consider bringing your house up to date, too, and stop adjusting the temperature on your air conditioner by hand.
Buy an air conditioner unit that's fitted with a remote-control sensor, if possible. These come with their own remotes. Most small air conditioners can cool more than 200 square feet, and many of them up to 600 square feet or more.
Place a window unit in a window that faces a chair or a sofa in the room. You don't want to defeat the purpose of having a remote control by having to stand up to get a direct line to it. Ideally, situate the air conditioner where it's remote-accessible from any seat in the room.
Tune all your units to one universal remote control. These infrared remotes operate on the same principle as a television universal remote and allow you to input codes from the units in the various rooms of your home or office. Carry the remote with you from room to room. If you're leaving a room for an extended period, turn the temperature up to save energy.
Adapt an air conditioner to use remote control with a kit that plugs into the wall. Plug the AC unit into the other end of the electrical attachment and aim the remote control at this source. Again, make sure that the infrared receptor is in a spot that you can access easily from your seat.
