I’ve lived in a few places in San Diego over the last 20 years; 4 relatively close to the coast and 3 further inland. In that time, I had air conditioning in the places inland, but rarely used it. In fact, when we lived 20 minutes more inland than we do now, I don’t recall turning on our A/C for the first few years we lived there; we used ceiling fans and just dealt with the warmer days. So when we bought our house and remodeled it, adding A/C didn’t even cross my mind. We’re pretty close to the coast, and I figured we’d get a coastal breeze. Within the first year of living here, I knew that this was a bad decision. It turns out that last year was the hottest year on record in San Diego with 12 days over 90 degrees at the airport whereas there are normally 1-2 days over 90 degrees. I thought maybe I had become a wimp and couldn’t take the heat (well, that still may be true), but the facts confirmed that I wasn’t completely crazy.
So, at the beginning of this year, I had air conditioning installed. It was pretty painless as we already had duct work, a thermostat and a place to put a compressor. Since the installation, we’ve turned it on 3 times. Twice last week because the humidity was so high and one of the days, it rained which required us to close our windows (it was well over 80 degrees outside so closing up the house rapidly increased the house temperature). I really hate to use air conditioning as it is a dry air and it isn’t cheap, but with outside temperatures increasing, this was a wise decision. We still use ceiling fans as much as possible, but knowing that we have this backup just makes our house even more comfortable.
