Four Ways to Cool 2 Rooms with 1 Window AC Unit

Four Ways to Cool 2 Rooms with 1 Window AC Unit

Can a Window Unit Cool Multiple Rooms?

Do you swelter watching TV in the living room while others sleep comfortably in a cooler bedroom? Is one room always cooler than other areas of your home because it’s the only room that gets no sun?

If you don’t have central air conditioning, you know how hard it can be to keep your entire home cool enough to beat the Texas heat. You could put a window AC unit in each room, but that’s not practical or cost-efficient.

Let’s take a look at a few practical ways to beat the heat with only one window unit.

How to Get Cool Air from One Room to Another: Use Fans!

Most people have at least one fan of some type that can help circulate cool air, but not all fans can be used in the same way.

  • Floor Fan

    To cool off a room adjoining the room with the window AC unit, close off any openings or entrances except for the one leading to the room you want to cool. Position your floor fan in the doorway with the fan blowing into the adjacent room. This will allow the fan to draw cool air from the air-conditioned room and deliver it to the non air-conditioned room.
  • Desk Fan

    This option works just like it does with the larger floor fan. However, it’s better if you use the largest desk fan possible, usually 30 centimeters in diameter, since the larger the fan diameter, the more cool air that can be drawn in and used to cool down a room. Although this isn’t the best option, due to the smaller size of desk fans, it’s better than nothing when you’re virtually melting in a room that doesn’t have the AC unit.
  • Box Fan

    The difference between using a box fan and a floor or desk fan is the placement of the fan itself. Instead of putting the fan at the doorway connecting the two rooms, put it in the window of the warm room, positioned so that it blows outward, forcing the warm air to be drawn out of the room. In the room with the unit, crack an adjoining window a few inches to help circulate the cool air better.
  • Whole House Fan

    This is a fan installed into the ceiling on your home’s top floor. When the outside air is cooler than the temps inside your home, turn this fan on and open the windows. The cool air from outside will be drawn into the home and circulated throughout. If you have a window AC unit, turn it off and let the fan and open windows do the work. In fact, it’s imperative that one window be open; if all windows are closed, your house will depressurize, which can be dangerous.

Additional Tips from the Texas AC Specialist

Of course, don’t forget the usual energy-saving, heat-beating tips, such as keeping your shades drawn and as many lights off as possible. You could also put heat-reflecting film on any window that takes the brunt of the sun.
