Hmm, this year we had that extra cold winter that turned into a mild spring, so I think we mostly held out until around Mar, and even then it hardly ever ran. I run the fan, but the AC hardly ever kicked on.

Usually in Houston, it's possible to have the AC on in any particular month. It's not unusual for the temps in Dec or Jan to occasionally be in the 80s which feels very warm when the rest of the weather is in the 60s.

I rarely have the house open. I wish I could do it more, but the humidity is usually the problem.

When my New Orleans family visits they are always amazed when we open up the house in the early evening. Guess that's pretty rare down south!

I forgot I had AC. I took the baby to the park this morning and had to wear a light jacket! I am enjoying the relatively low utility bills though.

We run our AC a lot, but largely just because we don't get great circulation without it, even with some windows open. For example right now my weather station reads 63 outside and 78 inside.

It has been unusually mild so far this spring/summer - many days in the 70's or 80's and very few 90's or 100's (if any) so far. I don't mind one bit. It is a bit odd for this area though when some summertime mornings are so cool and damp that it's practically drizzling and I need wipers and headlights on the way to work...
