In the summer, we use a window air conditioner in our bedroom to be able to sleep comfortably at night. It takes a while to cool, and I know it uses quite a bit of energy. Here are a few steps we take to reduce total energy usage:
- Set the mode to "energy saver," which turns the fan off periodically once the temperature reaches the set point
- Set the thermostat to 78F / 26C
- Keep the bedroom door closed when the AC is running
- Keep the bedroom blinds closed during the day so that the room doesn't heat up too much
What are some other steps I could take?
There is a gap of about 2cm under the bedroom door... should I seal this? Will it make much difference? I also didn't invest much time sealing around the AC where it goes through the window. There are no large gaps, but are there ways I could improve the air sealing?
