For most families, it does not matter what season of the year that it is. It could be the dead of Winter or the peak Summer months, and even Springtime or the fall. Whatever time of the year that it is, there is at least one Heating and Air Conditioning question that is bound to be asked more than once! That question is “what setting should every one of us have the temperature control set at to maximize comfort?” At the same time, every one of us wants higher indoor air quality, and a temperature control that won’t destroy us financially. Some people know that you should set the temperature to your ideal setting, and leave it there all the time. That is intentionally leaving your A/C on even when you are not home, and you will be using A/C to cool an empty house! The reasoning is that it takes more energy to heat a cold home or to cool down a hot house than it takes to maintain your ideal temperature setting! The other group believes that the heating or cooling should be reduced at the temperature control if you plan to be gone for a long time – more than a weekend, I would say. That thinking comes from the idea that the energy you will be saving by lowering the temperature control for those times when the home is empty will offset any costs you might incur by trying to heat up a cold home or air condition a hot home in your absence. However, leaving your heating or cooling machine on all the time honestly costs you more at the end of the month. Just use it when you need it!
