HVAC Maintenance: When Best To Replace Pleated HVAC Filters

March 17, 2023

When it comes to maintaining the efficiency and quality of your HVAC system, understanding how to replace and clean the pleated filters is essential.

Pleated filters, also known as high-efficiency particulate air (HEPA) filters, are meant to capture particulates from the air as it circulates through the HVAC system. This helps to reduce the amount of dust and debris that enters the system and is released into the air. In order to keep your HVAC system functioning optimally, it is important to know when to replace filters. This blog post will discuss the importance of replacing pleated HVAC filters, the guidelines for when to replace them, and the benefits of doing so.

1. Monitor filter condition regularly

It is essential to monitor HVAC filters regularly to ensure they are in proper condition. In order to maintain optimal air quality and energy efficiency within the facility, pleated HVAC filters should be checked on a regular basis. If the filter condition is deteriorating, it should be replaced with a new one to reduce dust, pollen, and other airborne particles. Regular maintenance of the filter is key to ensuring the HVAC system operates optimally.

2. Change filters when they become clogged or dusty

Pleated HVAC filters are designed to remove airborne particles from the air that passes through them. The efficiency of the filter decreases as the filter becomes clogged or dusty. To ensure optimal efficiency, it is recommended that the filter be changed when it becomes noticeably clogged or dusty. This should be done at least once every season or more often if the filter becomes clogged or dusty faster than expected.

3. If the filter is beyond cleaning, replace it

After a certain amount of time, the filter will no longer be able to be effectively cleaned and should be replaced. If the filter is beyond cleaning, it is essential that it is replaced as soon as possible. Failure to replace a pleated HVAC filter on time may cause the filter to become clogged, reducing airflow and negatively impacting air quality. Additionally, the HVAC system may become overworked, leading to increased energy costs and potentially damaging the system itself.

4. Ensure the new filter is the correct size for your HVAC system

When replacing your HVAC filter, it is important to ensure that the new filter is the correct size for your system. A filter that is too large may reduce air flow and cause the furnace to overheat and malfunction. A filter that is too small may allow dust and debris to pass through, reducing the efficiency of the HVAC system. To be sure you have the correct size filter, make sure to measure the old filter before purchasing a new one.

In conclusion, replacing pleated HVAC filters does not have to be a daunting task. With the right guidance and materials, you can easily replace them yourself and save money in the long run. Remember to regularly check the filters to ensure they are in good condition and replace them when necessary. Doing so will help your HVAC system run efficiently and maintain your indoor air quality.
