North Texas (Dallas, Ft. Worth, etc.) get pretty cold during the winter. I've spent a fair amount of time in North and Central Texas and while high AC bills during the summer (i.e., mid-April to early October) are common, the single highest electric bill I've ever had was one January in North Texas when I was living in an apartment with an electric heater.
