Hi, I am a new member and am glad I found this site. Perhaps someone can help me with a problem that I am having with my furnace. I live in Michigan and recently purchased a house. A deciding factor in the purchase was that a new furnace had been installed, albeit, it was in the attic. This attic furnace has been a problem. It creates ice dams on the roof and causes it to leak. I have been getting water inside the house because of this issue. The furnace was originally in the utility room, so now that the room is empty of a furnace, it is too cold to utilize. I have to run an electric heater to keep the room warm if I want to do any type of a project. Worst of all, the furnace runs constantly when the weather is cold, even though the thermostat never registers above 64 degrees. For the past few days the weather in Michigan has been frigid with tempertatures 10 degrees below zero when you factor in the wind chill. In frigid weather the house is extremely cold although the furnace is running, and running, and running and running. A few times I set the thermostat at 60 degrees just to stop the furnace from running. Doing that proved to be a mistake because it was almost unbearably cold. My November and December heating bills were astronomical, and that was before the recent cold weather moved in! The attic furnace is horizonal, but I would like to have it moved back to the utility room, which was the original location for the furnace. (Originally there was a boiler furnace in the utility room.) Even though the current "new" furnace is low effeciency, I will need to keep it because right now, paying off the high energy bills has taken a priority. There is not enough room to lay the furnace horizonally in the utility room. Can it be installed vertically. The house does not have a basement, but has a crawl space. The duct work for the furnace runs through the attic. Any advice you have would be helpful. Thank you.
