Whenever it is possible to give your central heating and air conditioning plan a break, by all means do it.
I was able to do this plus save on energy use plus in turn save money. But how can you do this? Well there are a few bizarre ways. The way I did it was by getting a smart thermostat. By having a smart thermostat I was able to reduce the use of our central heating and air conditioning plan by almost 50 percent! This was due to the fact of being able to have the heat or the air conditioning unit off while I am out of the apartment for long periods of time toiling or doing other things. The other way you can give your central heating and air conditioning plan a split is to buy a portable air conditioning plan plus a portable space heater. These can also reduce your Heating plus A/C plan USge. Because you can run the portable air conditioning plan or the portable space gas furnace half the time plus then run the central heating and air conditioning plan the other half of the time. I never tried that system but a friend of mine did plus they saved about the same amount I am saving by using our smart thermostat. So both of those methods are superb energy savers. The cheapest is the way I went. And that was simply just buying a smart thermostat plus making superb use of it in every single way through the app that comes for your cell PC plus your laptop to operate it.
