Since we bought the house my mom gives me a call every two weeks or so and asks/reminds me of the little things I need to stay on top of. Occasionally it's irksome, but for the most part I appreciate her looking out for us/our house.
Last week's question was about the air filters for the furnace. It was a busy day so I said no, added air filters to the list* of things to do. Driving home I got upset at myself for forgetting but then I remembered. We haven't run the AC since the first two weeks after we moved in!
Even though we lack an IKEA, this city is great b/c it gets so cool overnight. Daytime high's of 90 usually mean overnight lows in the 60's. The combination of good insulation (thank you builders!), open windows at night, and the occasional fan has keep the inside temp pretty moderate. So based on my doctors recommendation to change filters monthly, we've saved $20-30 using fresh air to cool the house.
*which has grown exponentially since we bought the house. Not complaining, just saying.
