my electric furnace blows cold air sometimes...?

sometimes it works fine, other times it can't keep the place warm, it'll be running all night and not be close to what I have it set at. Woke up to 48 degrees (F) this morning!! Right now it's blowing warm and getting back up in the 50s, but not sure for how long. What could be the problem?
