This is a very good point. Our utility bills more than doubled when we switched out from 3500 sqft (medium ceiling) home to 5000 sqft (high ceiling) home. We are about to move in to a 2400 sqft house (low ceiling) where utility bills will be 4 times less than current 5000 sqft house.My only question would be if the new house changes your spend significantly. Ours did, but so far well worth it. More switching costs than we anticipated, as we’ve done improvements on the house, but they have been discretionary and the funds have been there.
