Here in Northwest Indiana, my outdoor thermostat had triple digits the other day, but so far we have managed to not turn on the A/C. There are a lot of factors going in our favor for that feat:
1) Big house with three levels. We don't spend much time on the top level this time of year.
2) Lots of shade from mature trees.
3) Use fans in the top level exhaust out the heat as soon as the outdoor temp becomes reasonable.
4) Less than 1/5th of a mile to lake Michigan so we spend the hot parts of the day at the beach and play in the 62 degree water.
I bought a condo in a 100 year old building that does not have central air conditioning. I had been looking at that building for quite a while and was concerned about being at the top of the 10 story building for the purpose of staying cool. Well also, I don’t like elevators.
I ended up buying a condo on the second floor
.
So I’ve been spending this week sleeping there for the first time since we bought it nearly 2 years ago and the small air conditioner I have is keeping it comfortable. No problem. Granted I did not stay there last week when the temps were in the 90s with very high humidity, but this week with low 90 temps and very low humidity things are fine.
