I've done three winter with no central heat. We have three space heaters we use if the house is going to get below 68degrees. If the AC had gone out no dice we would have just gone with the central unit right then. I've spent weeks on end because of hurricanes with no AC. Its no go for me or the house.Ouch! I'd like to say I'm glad it wasn't the AC that broke in the middle of August this timing isn't much better with possible snow and lows in the mid 20s coming.
