Hi there, I'd love a little advice from the DISverse. My husband and I are looking into a townhome to rent. We're currently in a 850 sq. ft. apartment. The townhome is three stories, with two bedrooms on the second floor and one bedroom (which we'd keep as a guest room, to be used once or twice a year) on the third floor. Total square footage for the townhome is around 1100. We love everything about it, but I'm worried about cooling costs. Heating likely won't be too much of an issue, as we live in the south and there's a fireplace. I know the second story of a home will get much warmer than the first floor ... are power bills for three-level homes just outrageous compared to single-level homes? I know I'll be paying more because there's more square footage, and power around here comes at a fairly modest cost (I pay 80-100 per month now). Anyone have advice on this they'd be willing to share? TIA.
