How to Know When it is Time to Change Your Air Filters

We all hear repeatedly how important it is to change the air filter in our homes, but how do we know when it is time to do so? Generally, HVAC companies recommend changing your filter every 90 days or 3 months. However, how often you need to change them can depend on your environment, the age of your system, or pets that live in the home. It is important to check your filter every month and replace it as soon as it is dirty.

A dirty filter gone unnoticed can cause bigger problems for your AC unit. Some of these issues include:

Reduced Airflow

A dirty air filter can restrict airflow into the air handler, making the fan motor work harder and leading to increased energy consumption and higher utility bills. 

Poor Air Quality

Dirty filters cause dust and other pollutants to build up, spreading allergens throughout your home and damaging your AC system. widget

Increased Repairs

A dirty filter can make your AC less effective, which can lead to an increase in repairs.

Shorter System Lifespan

Neglecting to change your air filters can cause system breakdowns and shorten the lifespan of your HVAC.

Now that you know the damage a dirty filter can cause, here are some signs that your filter may need to be replaced:

• A visible coating of dirt covering your filter’s surface
• Extra dust accumulating around your home
• Weak airflow from your vents
• Noticeable loss of cooling power in your HVAC system
• Sounds of strain when your HVAC system is starting up
