I know nothing about furnaces but something about the way my furnace works doesnt makes sense to me and I was wondering if someone could give me an explanation...
I have a Carrier Weathermaker 8000 58WAV furnace. It blows air continuously. From visual inspection it looks like it draws air from the basement. It cycles between warm and cool air. The problem is where I live in the winter it gets extremely cold(can get as cold as minus 40 degrees). The house is very old and the basement is very cold. So the furnace cycles between very warm and very cold air which is very uncomfortable and I can't imagine it being very efficient. Is this a normal setup for a furnace? This is my 1st home and Ive only lived here for 1 winter so I know very little about this stuff. I remember my parents furnace didnt blow air continously. It only blew air on the warm cycle. That seems to make much more sense to me than cycling between very cold and warm air.
Thanks in advance for any insight
