In Ca, the heat went off mid March, went on mid October. Now, we are in Co, weather is just starting to get cool and we have had only one evening when it was cold even to warrant heating. We invested in portable electric heaters. Brought one in to heat one room and it heated the whole house. And we have two furnances! Guess we won't be using one furnace much this winter. The gas company wants to raise their rates 20% this winter, hopefully not.
