Had to break down and turn the air conditioner on. We've been blessed this spring with really mild weather (temperature wise, at least!) and I've been able to avoid it.... but then, yesterday, it hit almost 90 --- so, the AC had to go on.
I live in a 1957 house with massively drafty windows, and NO shade on the house whatsoever. (We had two gorgeous trees that provided lovely shade a few years ago, but they developed some serious structural issues, so they had to come down before they fell down). I rent the house, and the AC unit is probably close to 20 years old. Now while it would be great if my landlord would replace the entire system, the landlord is also my Dad. I pay an extremely reasonable rent for the area, and he's put a lot of money into the house already. Quite honestly, I don't want him to HAVE to put any more money into it, so I try to put as little stress on the system as I can.
The summer absolutely spikes my power bills. Remember all that griping I did in February about the natural gas bills? You ain't seen nothing yet! ha.
