Changing or cleaning the filter
The first step is finding the filter. It may be behind the bottom panel of your indoor unit, or there may be two filters.
- When removing a filter, make sure you insert the clean filter with the arrows on it pointing in the direction of the airflow.
- When replacing your air handler filters, always use the same size and type that was originally supplied.
- If you have a semi-permanent filter, you can take the filter out of the frame and vacuum it.
- If you have disposable filters, they should be replaced every month with filters of the same size.
