Your air filter is the first line of defense against dust, pet hair and debris. When it becomes clogged—or isn’t changed regularly that buildup can collect directly on the evaporator coil, just like you see here.
A dirty coil restricts airflow and forces your system to work harder, which can lead to:
• Reduced cooling
• Higher power bills
• Longer run times
• Frozen coils and water problems
• Costly cleaning and premature system failure
Check your filter monthly and replace it whenever it’s dirty. Most homes need a new filter every 30–90 days, but homes with pets or heavy system use may need changes more often.
A simple filter change can help keep your system from looking like this!
