I was talking to someone the other day and they brought up a pretty good point I haven’t really thought about. The point was that hardly anyone uses furnaces these days as a form of heating. Furnaces are what everyone used before central heating and air conditioning became the normal thing. Air conditioning in those days was usually provided from a huge window air conditioning unit that sat in people’s living room windows. But the heating was either a gas furnace or an electric furnace. It was much to my surprise that there were some people that still used furnaces. Usually those with older homes that were not built to have central heating and air conditioning. And the people that live in those kinds of homes that still have furnaces just don’t want to put the money out to have the ductwork laid and the house converted to a more modern heat and a/c method like central heating and air conditioning. But seriously, other than these one off situations, who really uses furnaces anymore for heating? My grandparents when they were alive even converted their home to central heating and air conditioning once they could afford to do it. And this was in the early days of central heating and cooling too! I have fond memories of growing up with a furnace for heating in the winter. But it is honestly something that I would not want to deal with this day in age. It was too much headache to maintain. Central heating is the only heat for me!
