Anywhere you look, whether it’s a blog like this one or your air conditioner’s owner’s manual, you’ll be told to change your AC air filter regularly. Most of the recommendations say it should be done once a month during the summer, and at least every few months when your air conditioner is running less of the time. But you’re not always told why!
In our experience, people are more likely to do something if they understand the importance of it and what could happen if they don’t. So we’d like to tell you all about what your AC air filter does, why it needs to be changed, and what can happen if you don’t change it.
