Energy Star recommends checking your HVAC filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months.

Why so often? And what are the benefits? We are glad you asked!

  1. Extend the Life of Your System: Dirt and neglect are one of the leading causes of failure for heating and cooling systems and a clogged air filter can cause extensive damage to your system.  When the air filter gets clogged with dirt, it prevents the air from flowing properly throughout the system and left clogged long enough will lead to overheating. Replacing the filter is an easy way to lengthen the life of your system.
  2. Indoor Air Quality: A clean air filter will remove most of the dust and pollen particles that would otherwise be in the air. This is particularly important for children, elderly and anyone in your family suffering from allergies or asthma. With a new filter, your system will be able to purify the air, leaving it clean and healthy.
  3. Energy Cost Savings: With a clogged filter, your system must work harder to pump the same amount of air around your home. More energy is then required to make your heating and air conditioning work which can cause your energy bill to skyrocket. It is estimated you can save up to 15% on utility costs by keeping your air filter clean and in good condition.
  4. The Environment: Failing to clean and replace your air filter on a regular basis is failing the environment. As mentioned above, an air filter that is clogged means a harder working HVAC system. This can lead to more carbon monoxide and other greenhouse gasses being released than is necessary.

Economically, health-wise and environmentally it simply makes sense to frequently change your HVAC filter. Call us if you have any questions or there is any way we can help, (770) 942-2873.
