Start by Cleaning or Replacing the Filters
Experts recommend that you clean your air filter for your unit every 30 days. You could also just change the filter at these intervals, particularly if you are using the cheap filters that just don’t hold up as long. The key is to take some sort of action here to care for your filter.
Your filter has a challenging enough job without trying to work through a dirt-packed screen. After all, that is the job of the filter and it can do its job more effectively if it is nice and clean. Even if you clean your air filter, you should plan to replace it no less than once every 6 months.
This is one of those steps that tend to be forgotten. Try setting up a routine schedule so that you remember to both clean and replace your filters on a regular schedule.
