Whenever it is possible to provide your central heating and a/c method a break, by all means do it. I was able to do this and save on energy use and in turn save money. But how can you do this? Well there are a few weird ways. The way I did it was by getting a smart control unit. By having a smart control unit I was able to reduce the use of my central heating and a/c method by almost 50 percent! This was due to the fact of being able to have the heat or the a/c off while I am out of the home for long periods of time working or doing other things. The other way you can provide your central heating and a/c method a chop is to buy a portable a/c method and a portable space heater. These can also reduce your Heating and Air Conditioning method USAge. Because you can run the portable a/c method or the portable space oil furnace half the time and then run the central heating and a/c method the other half of the time. I never tried that method however a friend of mine did and they saved about the same amount I am saving by using my smart control unit. So both of those methods are wonderful energy savers. The cheapest is the way I went. And that was simply just buying a smart control unit and making wonderful use of it in every single way through the app that comes for your cell iphone and your tablet to operate it.
