How Do I Add Central Air Conditioning to A 100 Years Old House?
Question:My house is 100 years old and has forced hot air heat. The gas furnace is a 90% efficiency and 5 years old. I have a 7 years old central air condition system that is used but in very good shape. Does anyone know if I can somehow combine the two. I am very cost conscious, so I would like to do it myself.
Please off any and all suggestions.
Thank you

I would suggest a window unit so as not to mess up the stately aspect of an old house that probably isn't insulated so to at least have one or two rooms comfortable ,like the bedroom, a window unit can be removed without unsightly damage to appearance to your home, and much cheaper in the long haul.
First, yes it can be done but consider these things . Your old a/c unit. how long has it been sitting? Was a vacuum pulled on the condensing unit when it was disassembled? To install even a used unit you must has access and knowledge of air conditioning tools. You must be state certified to handle freon. You must be able to solder copper pipe and then pro-form many other tasks , such as, install a new filter drier to system, modify the sheet metal in furnace to accommodate the a-coil etc' there is also the thermostat to be rewired; you may not have enough 18ga thermostat wire in the pre-existing set-up and you will then have to pull another wire set in to be able to run the outside condensing unit. A 220 volt dis-connect must be installed outside by an electrician etc.
You might want to think about all this first. good luck!
Honestly, considering the age of the house, you really don't want to mess up the integrity of it with this kind of project. You really need to consult a pro. Maybe you could find one who is willing to work with you or use your equipment in order to cut costs. Most companies offer a free in home consultation in order to get a quote.
Good luck!
Really, it would be wonderful to a/c this home but you have more to consider than the a/c unit for the whole house, you have to consider the insulation that is already there it will cost you an arm and a leg to a/c the house unless its insulated ceiling, walls and windows. Most homes that old do not have any insulation. Maybe you could just do one room with a window unit, I speak from experience and my old house was never cool, just hot and muggy and the electric bills humongous.
