We are very happy with room temp around high 70’s, that might explain the difference. Downstairs almost never reach 80. On a hot day upstairs can hit 84 by later afternoon, then AC comes on to bring temp down to 79. That likely explains why we rarely turn on the AC. If we have the AC on to bring room temp down to 71, I can definitely see the bill double.[/quote]
Yep, that explains it! If we could, we’d have the A/C set on 68, but know that’s just asking for too much. We make it up a bit in the winter time because we keep our heater set at 58-60 degrees. 🙂
