How Often Should I Change My HVAC System’s Air Filter?

Changing your HVAC’s air filter is the most important self-maintenance you can do to keep your HVAC system running smoothly, extend the lifespan of your cooling/heating system, save on utility bills, and keep your home’s air quality healthy.

But how do you know when and how often you should be replacing your HVAC system’s air filter?

Well, there are several factors that can affect how often an air filter needs changed, some of those are:

  • Home’s location
  • Number of people in household
  • Climate
  • Type of HVAC/filter
  • Quality of your city’s air/pollution

You should check and/or change your HVAC’s air filter at least twice a month if any of these conditions apply to your home:

  • In a consistently humid climate
  • Have pets
  • Persons living in the house with respiratory problems or allergies
  • Frequently use a fireplace
  • Run your AC 6+ months out of the year
  • Live in a windy or fire prone area

For homes with these conditions, it is best to have a continual supply of filters. Action Air offers cost efficient packs and will help you determine which type of air filters are best for your HVAC system to insure maximum air quality and savings.

Action Air Tip: Even if your filter is not dirty, be sure to check for dampness, mold or moisture, especially if you live in a humid climate. Immediately change your air filter if you see any signs of moisture as it can lead to mold and result in health problems.

If your home does not have pets, is a single occupant home, and has quality outdoor air, your air filter can go as long as 3 months before needing to be replaced. However, you should always check your air filter at least once a month, especially during the months where your AC is consistently running.

If your HVAC air filter seems to get dirty quickly – even after you just changed it – try a different type of air filter. There are more types of air filter than you may think, including:

Depending on your HVAC system and home’s conditions, a specific type of air filter could prove to be more efficient – even if the price of the filter is more upfront, it could last much longer than economy panels.

Regularly replacing something as simple as your Air Filter can help you avoid major costly repairs down the line. Here’s everything you need to know about your HVAC Air Filter.

What’s the importance of a clean Air Filter?

The air filter in your HVAC system prevents large airborne particles from entering the system and jamming up the machinery. A dirty air filter can cause reduced airflow or a pressure drop in the system which can lead to a lack of any air filtration. These conditions can cause your system to work harder, whether in a heating or cooling season, which makes it run less efficiently giving your AC or Heating unite a shorter life span.

How does moisture effect your system’s air filter?

If moisture gets into a dirty filter, it can contribute to mold growing inside the filter which can then spread throughout your entire home through your HVAC system. Mold can cause serious health issues to your and your family, not to mention the costly repairs to the compromised system and source of the moisture problem.

What Type of Air Filter Do You Need?

There are several types of filters, including ones that are disposable, biodegradable or more advanced filters that are designed to maximize air filtration. You can purchase economy packs of filters for some cost savings through Action Air.

Our HVAC professionals will be able to help you determine the best filter for your needs and your air filtration system.

The HVAC filter should be replaced no less than every three months for optimal system performance, but often should be changed more frequently. It’s easy to check your filter to see if you need to change it more often. Typically you should change the filter every month if:

  • You have pets,
  • You typically run your unit 6-12 months out of the year
  • Someone in your home has allergies or a respiratory condition, if you live in a windy or wildfire prone area, or if you have a fireplace that you occasionally use.

Action Air Tip! It is critical you change the filter immediately if the filter is damaged, damp or shows signs of mold growth on the filter.
