How Do You Know When Your Home’s AC Filter Needs To Be Replaced?


Your home’s air conditioning keeps you comfortable during the hot summer and also helps to keep the air in your home clean and free of allergens. The air filter is one of the essential components of your air conditioning system, as it is responsible for removing impurities and debris from the air that is circulated through your home. Over time, the filter can become clogged with dirt and other particles, leading to decreased efficiency, increased energy costs, and even damage to your AC system. In this blog post, we will discuss how to know when your AC filter needs to be replaced and why it’s important to do so.

Signs that Your AC Filter Needs to Be Replaced

It’s important to check your AC filter regularly to ensure it functions properly. Here are some signs that your air filter may need to be replaced:

Increased Energy Bills

When your filter becomes clogged with dirt and debris, your air conditioning system has to work harder to circulate air throughout your home. This increased workload leads to higher energy consumption and, ultimately, higher energy bills.

Reduced Air Flow

Another sign that your air filter needs to be replaced is reduced airflow. When your filter is clogged, it can prevent air from flowing through your AC system, leading to reduced airflow and decreased cooling efficiency. It’s better to call an AC repair technician to diagnose your air conditioner in Highland, CA.

Dirty Filter

One of the most obvious signs that your AC filter needs to be replaced is that it is clogged with dust and debris. This can restrict airflow through your system, reducing its effectiveness. If you notice a thick layer of dust or debris on your air filter, it is time to replace it.

Unpleasant Odors

If you notice unpleasant odors coming from your air conditioning unit, it may be a sign that your filter needs to be replaced. A dirty filter can lead to the accumulation of mold and bacteria, which can cause foul smells to emanate from your AC unit.

Allergy Symptoms

If you or someone in your home is experiencing allergy symptoms, such as sneezing, coughing, or watery eyes, it could be a sign that your air filter needs to be replaced. A clogged filter can cause allergens to circulate throughout your home, aggravating allergy symptoms.

How Often Should You Replace Your AC Filter?

Most experts recommend replacing your AC filter every 30-60 days. This may vary depending on your system, home, and lifestyle. If you have pets or live in a dusty area, you may need to replace your filter more frequently. On the other hand, if you have a newer system, you can wait longer between filter changes.
