What Are My Options

Believe it or not, there are many ways that you can cool your room that has no windows. Consequently, it becomes the decision of the homeowner to determine what item or method works best for their home. Let’s review the list of options for cooling a windowless room.

  • Mini split AC unit – this unit cools the air inside the room and expunges the heat through the outside unit. You will be required to drill a hole about three inches wide to connect the indoor unit to the outdoor unit.
  • Portable air conditioner – purchase a stand-alone portable AC unit. It will suck in the warm air and cool the air through the condensation unit. Then spit the cooler air into the room. The excess condensation gets stored in a reservoir that just needs to be emptied once it is full. It is a ductless air conditioner and a ventless air conditioner.
  • Through wall AC unit – this is an option if you are willing to carve out a hole in your wall to place the ac unit. This is a more permanent idea that requires you to be ok with a new hole in the wall of your home. Install this in a room with no windows.
  • Evaporative Cooler – uses cold water or a bowl with ice placed in its tanks. The air is sucked in and travels across the cold air or ice, which makes the air colder as it is pushed into the room. Leave the door open so that the warmer air can leave the room.
  • Ceiling Fan – installing a ceiling fan will allow you to increase your ac temperature and save money on your electric bill.
  • Two fan method – one fan is pointed at the ceiling to circulate the air and the other fan is pointed at the door to push any warm air out of the room.
  • Exhaust fan – you can open the door to your bathroom and turn on the exhaust fan. The exhaust fan will pull the warm air out of your room and into the outside. This works when the inside air temperature is hotter than the outside air temperature.
  • Replace your light bulbs – if you are using incandescent light bulbs, they release a lot of heat. Also, if you want to reduce the amount of heat energy being released by light bulbs, switch your bulbs from incandescent to LED.

Other Recommended Maintenance

Now that you have learned about cooling a room with no windows, let’s take a look at other areas of maintenance. One of those is increasing natural light. In other areas of your house where you do have windows, you can increase the natural light. You can do this by making sure your furniture doesn’t block the light and not using heavy drapes. You can use glass doors or skylights to help. This will also save on your energy bill.

Another area is the lights in the home causing a fire. If you see a light flickering, this could cause a fire, depending on the cause. If the cause is a loose bulb or circuit overload, you might be okay. However, if it is a loose wire that is old, this could cause an issue and you want to contact a professional.

Lastly, asbestos ceiling tiles are not good for the home or anyone’s health. If your home was built between the 1920’s-the 1980s, there may be asbestos ceiling tiles. They are also called drop ceilings, suspended ceilings, and acoustic ceilings. The tiles are 2×2 or 2×4 and unless you have a professional sample of the material, it is hard to know if they are asbestos or not.

Call on your local home inspection team to determine which project is most efficient for cooling your room. Also, they can recommend a reputable contractor for the project.
