Filter Facts

Always change your air filters every 2 to 3 months. Why? Air filters will get clogged after prolonged use and restricted air flow will cause your a/c coils to get clogged.

In addition to restricted air flow, you may experience:

• Increased energy bills
• Added maintenance costs
• Air duct contamination
• Interior wall, ceiling and a/c vent dirt, smoke and dust build up
