I went over to my friend’s house for a barbecue last Saturday. We make a point of hanging out quite often. Cooking out on the grill and throwing back a few brews is how we love to celebrate the weekend, after all, especially in the summertime, of course. However, he texted me before I left my house to head to his place with a warning that his air conditioner unit had given out that morning. I figured we would try to make do. His house was indeed pretty hot and humid when I arrived. Fortunately, though it was warm outside, there was a bit of a cool breeze blowing through the trees now and then. He opened some windows and doors for ventilation and the cross breeze. As we were grilling, we got to talking about the air conditioner problem. He did not know what was wrong at first, so I started throwing out random suggestions. When I mentioned changing out the air filter, he suddenly froze and looked at me with a surprised expression. He couldn’t even recall the last time he had changed out the air filter. It must have slipped his mind for quite some time, because when I pulled it out, it was absolutely filthy. He made a quick drive to the store to get a brand new air filter right then and there while I finished grilling. Swapping the dirty air filter out for a new one may not fix the A/C problem entirely, but it will be a step in the right direction for sure!
