In the home that I currently live in there is no central heating or AC. The home is outdated and may have been built in the 1940s and there is lead paint on the windowsills. The need for an AC is truly important in the temperature in which I live. The shade from the giant oak tree in the backyard absolutely helps the home cool. Without central AC we have been able to manage with window component AC‘s for the past several years. Window component AC’s are much easier to manage in terms of replacement and repair! Replacing a window component AC is much cheaper than repairing a central AC unit. I’ve always been truly glad with the window component AC and how they cool only one room at a time. Not having central heat or AC has never been an issue because we’ve always had space furnaces as our primary source of heat. The space furnaces are fantastic and do truly well at heating a room.Heating and cooling only one room at a time is truly cost-efficient and saves energy. Our utility bills are much less than they would be if we had central heating and AC. Saving currency on utility bills allows us to travel more because we are not spending as much on central heating and cooling as several people. The space furnaces are a totally fantastic source of heat in my opinion. I like resting next to the space gas furnace while the rest of the home is cold in the Wintertide weeks. The only concern with having a space gas furnace is that it can cause a fire much quicker than a central heating component would.
