Are Air Filters Important for My AC Unit?

Don’t Let Dirty Air Filters Affect Your AC

Summer in Minnesota can range from hot to humid. When the heat cranks up, your AC acts as a saving grace. But what if your air conditioning system starts acting sluggish, kicking up your energy bills, or worse, stops working altogether? A simple, inexpensive maintenance step can help prevent this. The one overlooked culprit is clogged air filters.

Here’s why air filters are crucial for your home or business’ AC unit:

  • They protect your equipment: Air filters act like tiny shields, trapping dust, dirt, and allergens before they can enter your AC system. This prevents these contaminants from accumulating, which can reduce airflow, strain the system, and lead to costly repairs.
  • They keep you cool and comfortable: Clean air filters allow your AC to breathe easier, literally! Unimpeded airflow ensures that your system operates efficiently, pumping out cool air. A clogged filter forces your AC to work harder, leading to higher energy bills and potentially warm air.
  • They improve indoor air quality: Beyond protecting your AC, clean air filters also benefit your health and comfort. By trapping dust, pollen, and other airborne irritants, they contribute to a cleaner, healthier breathing environment for everyone in the building.

Now that you know the importance of air filters play, the next step is to know how often you should change your air filter.

The frequency of when you should change your air filter depends on several factors, including:

  • Pet Dander: If you have furry friends, you’ll likely need to change your filter more often to accommodate for the skin flakes in an animal’s fur or hair.
  • Climate: Dusty environments or areas with high pollen counts may require more frequent changes.
  • Air Quality: Poor outdoor air quality can lead to quicker filter clogging.

If none of the above apply to your household or business, a good rule of thumb is to check your filter monthly and replace it every 1-3 months, especially during the summer.
