We’ll thank Maya and Morgan Moody for the idea, but it was suggested last year at Josh and Sharon’s wedding that we consider getting a single-room air conditioning unit for our upstairs bedroom. As many of you know, we live on the second and third floor of a brick building in Soulard, and one problem with living on the third floor of a brick building is that it gets hot up there and stays hot, even past dark. Having our central A/C maintain a comfortable temperature on that third floor (when the thermostat is on the second floor, mind you…) means that it’s running almost constantly, along with fans, etc. in the bed room to make sure I can sleep.
Well, we received a “personal energy report” from AmerenUE yesterday in the mail, telling us how much power we’d used over the last few years living here. As the graph above indicates, in the warm months of June, July, August and September (average temperatures ranging from 71 F to 81 F…but we’re talking about 100 F days in there, too…), we decreased our average energy use by a few hundred kWh. In our monthly billing statements, this translated to a savings of $101.33 over July – September.
We bought the single-room A/C unit in late-June 2008. We spent a little less than $100 on the A/C unit.
I think we made our money back. 🙂
