The Importance of Changing your Home’s HVAC Filter

July 15, 2016

changing HVAC filter
Some home cleaning/maintenance projects can be easy to forget, despite their importance. Changing your HVAC filter is no exception, it can be hard to remember, but it is an important part of home maintenance. There are certain scenarios that require you to monitor and change your filter more frequently than others, as well as different types of filters to consider for your HVAC unit. Let’s take a quick look at the different filter options available, and at the scenarios that would lead you to change your filter more frequently.

Types of Filters

The size and type of filter used in your HVAC unit will somewhat determine how frequently it needs to be changed. Filters are made with paper, or similar material, and have a large surface area for collecting dust and debris. Filters come in all shapes and sizes, so it is important to take a look at your HVAC model to determine which filter is correct for your unit. Improperly fitted filters can allow dirt into the system, and can lead to damage in your unit. There are also HEPA filters available that last up to six months because of new technology. These filters understandably cost more, but last up to six times longer than traditional filters.

Frequency of Changes

Most HVAC filters need to be checked and replaced every month following inspection, especially if you run your HVAC unit at least six months out of the year. Additional scenarios where you will want to constantly change your filter each month include being a pet owner, a smoker (inside the home), you have a fireplace that is used (even infrequently), or if there is construction nearby your home. All of these scenarios lead to more dirt and debris in the air, and therefore take a heavier toll on your filter. If your home meets any of these criteria, it may be a good time to look into replacing your current filter with a HEPA filter that has a longer lifespan.

Additional Considerations

There are some circumstances where your filter should be changed immediately, even if it has been less than a month since your last change. If you check the filter and it is damaged at all, it needs to be replaced to prevent damage to your HVAC unit. Signs of moisture or mold of any kind are also a red flag, and your filter needs to be changed immediately, to prevent the spread of mold spores in your home. If you find your filter to be damp or moldy, it is important to have an HVAC company come out to investigate why your filter got damp in the first place, as it could signal a bigger issue with your HVAC unit.

Changing your HVAC filter is an important part of home maintenance, and can save you money and headaches in the long run, because it can prevent major issues down the road.
