3 Signs You Need to Replace Your Home Heating & Cooling Filter, Liberty, Ohio

When you move into a new home, there are many lifestyle changes and maintenance concerns that take your attention. While these issues are undoubtedly important, they can sometimes cause you to overlook your heating and cooling system. Though changing the HVAC filter is a relatively simple task, it can have a big impact on future repair and maintenance needs. Here’s how to tell when you need to replace the filter.

When Should You Replace the HVAC Filter?

1. Visual Inspection

It’s generally recommended that you replace the HVAC filter after three months of use—or more often if you have pets or allergies. The best way to determine if it’s time for a replacement is to check the filter in person. Look for holes and wrinkles on the filter that make it easier for dust to circulate in your indoor air. Built-up dust and dirt also indicate that a replacement is needed.

2. Inefficient Heating & Cooling

Though this could be linked to a wide variety of repair issues, start by checking the filter. Excessive dust restricts airflow, which makes it harder to heat or cool your home. Replacing the filter will help you avoid overworking your system.

3. Worsening Allergies

Individuals with asthma or allergies are more sensitive to the buildup of dust and other air pollutants. As the HVAC filter ages, it becomes less effective at keeping such contaminants out of the air, which can lead to worsening symptoms. A replacement filter will ensure better air quality and healthier breathing conditions.
