Memorial Day lit the blast furnace around these parts. But I resisted the temptation and didn’t crank up the A/C (much to the kids dismay). I trudged down to the basement this morning to replace the central air conditioner filter, in anticipation of the blessed event. After all, maintaining a clean central air conditioner filter is essential for optimum efficiency, right? But pulling out our old A/C filter? Now that was a shocker …

Our central air conditioning filter was hideous!

Holy cow … who wants to breathe that stuff? Okay, so maybe it wasn’t the worst I’ve seen, but sheesh …

I thought I changed the filter a couple of months back. Maybe it was a few.

I’ve always tried to keep at least one spare air conditioner filter wrapped up and on the shelf. Having a filter on hand takes that excuse away. Alas, I don’t always remember to pick up a pack of air conditioner filters when I’m at Home Depot or Lowes.

That’s gunna change. I’ve made a vow to be more aggressive about changing filters and marking down each change date on the air handler. Simple stuff. Who wouldn’t want their A/C unit to deliver the maximum flow of clean cold air with the least electricity?

Next up: dragging the window A/C unit into the office/computer room …
