I may be in the minority, but I decided to use a furnace for my heating.
I found that a furnace is much easier and cheaper to maintain than a full on central heating and air conditioning system unit.
I have a stand alone central air conditioning system to take care of my cooling, and the furnace takes care of the heating. I also like the way the furnace heat feels versus central heating. The fact that I have a gas furnace I think makes a difference. Because I think an electric furnace would be the same as central heating in terms of the way the heating feels. Central heating or any kind of electric heating for that matter has a dry feel as to where the gas furnace is more neutral. That is how I feel in my experience anyhow. Getting a brand new gas furnace was actually not as easy as I thought it was going to be though. Because most people these days go for central heating and air conditioning systems, a lot of heat and a/c dealerships do not stock any kind of furnaces other than commercial or industrial kinds for large buildings. So I actually had to have my gas furnace ordered from the heating and air conditioning dealership that I got it from. The installation was pretty detailed too. That I won’t deny. But I just prefer a gas furnace over a central heating and air conditioning system any day of the week! There is no question in the whole wide world about that.
