I use a furnace to take care of my heating in the nippy season of the year. I would much rather have a gas furnace than a central heating plus a/c. As a matter of fact, my air conditioner equipment is provided through some window air conditioner units. I recognize that central heating plus cooling is just too fancy to operate. I had it once a long while back in a beach property I was renting when I got out of university. And I would never ever get central heating plus an air conditioner for my own property. I honestly decided this after seeing the super high electric bills because of it! But let me tell you, I had an electric furnace that lately has been giving me those same outrageous electric bills in the nippy season. Because of it being electric, it is honestly not much different than central heating plus a/c equipment. But it does save a little money. I made the choice that I was going to get rid of the electric furnace for this reason plus get myself a decent gas furnace instead. I suppose you are thinking “is this person crazy?”, however I am not scared of gas products. I know how to take care of them plus how to make a gas furnace extremely safe… The removal of the electric furnace plus the installation of the new gas furnace was rather fancy plus was a sizable thing. I had to take off from my place of work to have it done. But when it was all finished, my property was heating just as wonderful as the electric furnace was!
