AC maintenance
True story, my air conditioning unit got on fire one time. Luckily, nothing else got destroyed in the process, and we put it out quickly. From that day on, I take its maintenance pretty seriously. You won’t believe how fragile these things can be. So better make sure no dust or dirt is sticking inside.
That’s why I always keep a bottle of WD-40 at hand to remove the dust that accumulates inside. Take care of your unit, and it will take care of you. No one wants to spend a hot summer with a broken air conditioning machine (or worse, a burnt one). Learn from my mistakes.
