Stop in for a cup of coffee

I have electric and natural gas in my house. We used to have oil but switched the system to natural gas when the AC needed replaced. The original furnace was from 1947 and we were running on borrowed time with that. All of the appliances and heat run on natural gas. The lights and ac are electric (obviously) overall in summer when the ac runs our electric is $140 and the gas is $30. In winter it balances out. The gas is usually $120 and electric is about $60 a month.
