I was super lucky to replace my oil furnace with a heat pump a couple of years ago, before prices of heat pumps and oil skyrocketed. I used to pay $600-700 every three months in the winter just on heating oil (I had a very inefficient 1950’s oil furnace in my poorly insulated 1940’s home). Now I have air conditioning and heating without spending hundreds of dollars. I wonder how much it would cost to fill the oil tank now.
