$124 for a 1500 sq. ft. house and during the time this bill was accumulating I also ran a couple of brooder heat lamps during the nights in the kennel because of newborn puppies. We utilize one window AC and run it manually which means the house stays at around 75o - 79o. Ceiling fan and a couple of portable fans run throughout the day and night. I honestly expected this bill to top $200 so you KNOW I was pleasantly surprised! I think I shall try disconnecting all the vampires though ......... can't hurt and will help!
