We often forget one of the most crucial parts of air conditioners: maintaining them. We either get lazy or do not realize the consequences of not maintaining our a/c units. Problems that we often encounter such as weird noises, unpleasant smells and fluctuations in temperature can easily be solved with consistent a/c unit maintenance.
Keeping your blinds closed during the summer can help keep your home cooler, by not allowing the hot sun to shine in and raise the temperature inside. To further improve on this tip, you can get thicker or darker colored blinds to reduce even more of the heat that can come in through the windows.
This is the most important energy saving tip to consider. A properly insulated home will keep the heat in, and the cold out. Consider adding insulation to the attic. Once you put the money into insulating your home, you will start to see your monthly energy bill drop.
