Air Filter Replacement

Dirty or blocked filters can easily make your ac unit to age faster by making it work harder to achieve the same level of performance. We recommend that you change your air filter every month or two, especially if you live in a high-pollen area or if you have pets. Air filters are inexpensive, and changing your air filter is an easy task and it does not require a professional hand. In most cases, you should simply be able to slide the old filter out and slide a new one in.

Determining When to Change the Filter

Choosing how often to change your air filters can depend on several factors:

  • Type of filter your A/C system requires. Since each type has a different life span, use that to help determine how often you change your filter.
  • The overall air quality of your city that you live in. If the air does not seem as fresh or clear as it used to, or you are having issues with allergies or frequent colds, you may need to replace your filter more often or choose a different type.
  • Are there pets (birds, cats, dogs, hamsters) in your home? If so, you may want to consider changing your filter more frequently or choosing a type of filter that helps with dander.
  • Number of occupants in the house. The more people in the home, the more dust and dirt flies around – consider changing your filters more often.
  • General air pollution in the city area or construction taking place nearby.

High-Efficiency Filters
