My house is generally comfortable, but one issue it always had was that the closet in the master bedroom was cold all winter. Although that closet is on top of the garage, it didn’t seem as if it should have been so chilly—there is a register in the ceiling, but it never seemed like we got much warm air from it. For lack of better ideas, we put a space heater in the closet during the winter.

When we replaced our air conditioner with a larger and more modern unit over the summer, we also had to start buying air filters in a larger size. We noticed that the air flow seemed better, but we didn’t think much about it. When the weather turned colder, we were surprised to discover that the closet in the master bedroom stayed nice and toasty. Apparently, all it needed was a better air filter to improve the flow.

There’s a useful lesson in that. Even when annoying issues seem as if they’re going to be around forever, sometimes they’ll just vanish suddenly when other things get improved.

I deliberated for a while on what sort of image I could add to this post to represent both cold and flow. I finally settled on this photo of people rowing in icy water.

That is definitely not something I would ever do, regardless of how adventurous I might otherwise get in rowing! The people in the photo look like they’re enjoying it, though, so I would say it’s good flow for them—well, as long as their boat stays right side up, that is!
