When It’s the Right Time to Change Your HVAC Air Filter?

Your HVAC system requires regular maintenance to keep it running for a long time. Changing air filters is one of the essential tasks to ensure a healthy HVAC system in your home. People have this question about how often to change air filters, and the answer depends on a lot of factors.

This article is all about detecting the right time to change your HVAC air filter.

Generally, it is suggested changing the air filter every 30 days if you use fiberglass filters. And when it’s a high-end pleated filter, you can be stress-free for about six months to get it changed. 

However, this countdown not necessarily works in every situation. There are more factors related to this issue.

Usually, you will encounter dirt and debris-filled in your air filter within 90 days, and you will feel the urge to replace it. 

The more the filter is with dirt and dust, the more you will experience complications from the HVAC system. It will start decreasing efficiency along with unpredictable system errors.

However, the following things will help you determine more if you need to change the air filter right away or wait for more.

1. If anyone in your home has allergy issues or asthma problems, it is better to change the air filter more often (every six weeks). Indoor air quality becomes polluted with an unclean air filter.

2. If you have pets in your home, it’s another reason to consider changing the air filter every two months. Pets’ fur can attack the filters, and the odor can keep indoor air polluted.

3. If you have kids or toddlers, it is suggested to change the air filter every 2-3 months. It is highly required to ensure quality air indoors, especially when you are with kids.

4. If you don’t need to use your AC for a long time because you live in a mild climate area, your air filter can last an entire season. On the other hand, if the AC needs to be used on a regular constant basis, you have to consider changing the filter every few weeks.
