Replacing central air conditioning filters frequently is an important part of keeping your home healthy. Depending on the type of filters you buy, these can catch dirt, dust, pollen, pet dander, and even smoke. Forgetting to replace these filters causes the air in the home to be unhealthy. Also, it can cause discolorations in carpets and walls. And it makes your units work harder than they need which makes them more susceptible to wear out quicker and leads to increased energy costs.
