How Often You Should Really Change Your HVAC Filter

The quality of the air you breathe is important, especially when it comes to the air in your home. At Summit Air Conditioning & Heating, we’re well-versed in the best practices for AC maintenance, especially regarding your system’s air filter. Replacing the filter is a straightforward yet effective way to keep your unit running smoothly — but how often should you really change it?

There are many benefits of AC maintenance and changing your filter only adds to them! This task reduces impurities in the air, preventing allergy-like symptoms and system breakdowns. Our HVAC technicians share the importance of air filter replacement and how the frequency of changes can affect your unit’s performance.

How Often To Change Air Filters: General Guidelines

The frequency of air filter changes depends on a few key factors, including:

• • The type of filter

• • The size of your home

• • If pets are in the home

• • Whether or not you have allergies

Our team is here to share a few general guidelines to consider when replacing this component.

Standard 1-Inch Filters

For most homes with a standard 1-inch filter, it’s recommended to change the filter every 30 to 60 days. These filters are great at trapping dust, but they fill up quickly. If you’re in a home with moderate traffic, pets or air quality concerns, lean towards replacing it every 30 days.

High-Efficiency Filters

If you have a high-efficiency filter, such as a HEPA or a thick pleated filter, you can go longer between changes. These filters last up to 90 days and sometimes even up to six months, depending on your home’s environment. However, it’s still important to check it periodically.

Considerations For Homes With Pets or Allergies

If you have pets or anyone in the household suffers from allergies, you’ll need to replace the filter more often. Pets shed fur and dander, which can clog the filter. Allergens like pollen or dust can trigger symptoms in sensitive individuals. For these homes, you should consider changing the air filter every 30 days.

Signs It’s Time For An Air Filter Replacement

Even if you follow the general guidelines, there are a few signs that will let you know it’s time to replace your filter.

Inefficient Airflow

If you notice reduced airflow from your vents, this can signal that the filter is obstructed with debris and needs to be changed. Weak airflow can make your unit work harder to maintain a comfortable temperature.

Unpleasant Odors

If you smell musty or stale air, the filter could be harboring bacteria or mold. This can affect the air quality in your home and make it uncomfortable to breathe. Replacing your filter will help improve both the smell and the air quality.

Visible Dirt Or Discoloration

Take a quick look at your filter every month. If it’s visibly dirty or discolored, it’s time to swap it out. Even if the filter doesn’t seem clogged, it can still be effective at trapping dust and allergens that need to be cleared away.

The Role Of AC Unit Maintenance

While changing the air filter is an easy and essential part of AC unit maintenance, it’s just one component of keeping your HVAC system in tip-top shape. Regularly scheduled maintenance with a professional technician ensures that your AC unit continues to perform well, which can extend its service life and prevent costly repairs.
