The answer to 'air filter maintenance tips' is to regularly inspect and replace your HVAC air filter. Air filters should be changed every 1-3 months, or more frequently if the filter becomes clogged or dirty. This helps maintain optimal airflow and efficiency in your HVAC system.
When changing the filter, turn off power to the unit and locate the filter, which is usually in the return air duct or at the air handler. Carefully remove the old filter and insert a new one, making sure it fits snugly. Choose a filter with the appropriate MERV (Minimum Efficiency Reporting Value) rating for your system. Higher MERV ratings capture more particles but can restrict airflow, so it's important to follow the manufacturer's recommendations.
