There are some simple things that you can do to keep your air conditioner operating in good condition. These are things that even a young person can be taught to do. I have seen some AC filters that looked like they hadn’t been changed in years. I have met adults who didn’t realize that was something that you are supposed to do. If your filter gets clogged, dust and dirt can get into the air conditioner causing it to wear down and not last as long. The number one reason that air conditioners break down is because of clogged air filters. Filters may cost you money but they will save you money in the long run because your system will be more efficient. The vinegar flush will help keep bacteria, mold and algae from growing.
