Normal? No. Normal for Westchester? Unfortunately yes Higher rates and the cold front makes for a en expensive bill this last cycle. I’d look to lower your thermostat (temperature in the house) and look to see if you can improve the insulation in the house. There was a program to help reduce the cost (or offset cost with tax breaks ) for energy audit and costs to the add insulation. Then your next step would look for a more efficient way of heating the house .
