For technical reasons, the upper floor gets more heat than the lower floor. And when you have an attic bedroom, it gets seriously uncomfortable during the summer for the residents there. So, you keep wondering yourself how to lower attic temperature.

Attic bedrooms offer more square footage and extra bedroom and such bedrooms increase the value of your house a lot. But these rooms will absorb more heat than the rest of the rooms in your house. Somehow if we can lower the temperature there, it will be just sweet. You will get some proven to be effective tips on how to cool an attic bedroom in this article.

7 Ways To Cool An Attic Bedroom

You have to make such bedrooms livable and to do so you have to do something about it. A pretty hot and stuffy attic bedroom is no use! Here are some hot attic solutions to make such bedrooms cool. You can talk to any HVAC professionals about the following options to determine which one will be ideal for your case.

  1. Inspect The Roof

The surface of the roof your attic should be reflective to stop absorbing much heat from the sunlight. If not, consider investing a little in reflective shingles. You can dramatically reduce the heat inside the attic room having such reflective roof shingles.

  1. Seal Any Gaps of Doors/Windows

How To Cool An Attic Bedroom

People don’t pay much attention to seal any small cracks and gaps of doors and windows located in the attic. Since such spaces are not exactly living spaces, so they don’t pay much attention to fix such issues.

But such gaps and cracks let outside hot air inside the attic room. Locate such gaps and cracks and seal them pretty well. You can go forward with caulking or weather-stripping. Fixing such issues first will help a lot to get the best benefits of any steps you take to cool down the room later.

  1. Install Oscillating Fans

That’s the simplest and easiest way to cool an attic bedroom with no insulation. Install one or multiple of such oscillating fans depending on the size and situation. I am not recommending any stationery fan because you have to get the most cooling benefit.

You will get the most benefit out of such fans if you install multiple of them. Install one facing it toward the attic. This will prevent hot air from touching the lower surface of the bedrooms. Install another one that will blow air directly towards you.

Do you have a vent there?

If so, install one there too to push out more hot air if it is not doing a great job already. If you can’t install such fans, try installing an attic fan. Here is how you can do it:

  1. Inspect Ductwork

Since you have an attic bedroom, you surely have ductwork installed in your home. Hire an HVAC professional to check the ductwork for further improvement. Improved ductwork will help to keep the entire house cool during the summer and warmer during the winter.

If there is no ductwork in the attic room, take professional help as well. If the AC system is powerful enough to cover extra footage, he will recommend installing ductwork there too. If the AC system installed is not that powerful, don’t install ductwork in the attic room.

  1. Install Window-Mounted/Portable AC

If you have no option to channel air to the attic through ductwork, installing an air conditioner is a pretty good idea. Depending on the size of the room, the capacity of the AC will vary too. And if you can install it on the window, get a window-mounted one. If this is not possible, get a portable one.

Sometimes, it costs less installing AC than installing ductwork in the attic.

  1. Ductless Split Systems

If for some reason, you can’t go for the ductwork or install any conventional AC, you can install the mini-split system. They are smaller than the conventional AC but pretty good to control the temperature of small places like the attic room.

  1. Thermostat For Independent Control

Create a thermostat zone for your attic room. This will let you control the room temperature independently. No matter whether you have the ductwork or you go with the ductless system, installing a thermostat is a great way to keep it cool. And the best part is you can keep it independent of your central thermostat system.
