Why Change Your Air Filter? Maintaining a healthy lifestyle is crucial, as breathing dirty air can lead to asthma, allergies, and other respiratory issues. Old filters can also cause system defects, leading to unwanted energy costs and repairs.

When Should You Change Your Air Filter? We generally recommend replacing your filter every 90 days to keep your system running efficiently and your air clean. However, this may vary based on filter size and factors like pet ownership, allergies, and the number of occupants in your home.
