If you really want to save money on how you heat and cool your home have I got a great suggestion for you! You really do not need to have central heating and air conditioning.
We all have been more or less brainwashed over the years that central heating and air conditioning is the only way to heat and cool your whole home properly.
This is not the case! You can buy a few ductless mini split air conditioning systems, then call your local heating and cooling company to have one of their certified heat and a/c specialists out to your home to convert the ductless mini split air conditioning system into a full blown ductless mini split heating and cooling system unit! This will save you a lot of money on energy use. I ended up doing this for my home and in the first year of using ductless mini split heating and air conditioning, I saved a total of five hundred dollars within the year on my electric bills compared to the year before when I was running central heating and air conditioning all the time. There is a major difference in energy use, and this is something that the electric companies and the makers of central heating and air conditioning systems do not want you to know. So I am telling you flat out about it now! Buy a few ductless mini split air conditioning systems and have them converted to also do heating and you will save as soon as tomorrow.
