How Often Should Air Conditioning Filters Be Changed?In Murrieta, we experience high temperatures from the summertime through late fall. That means it’s worth ensuring that your air conditioner is in tip-top condition and ready to provide the home comfort you deserve. One aspect of ensuring your AC unit runs as it should is replacing your air filters. However, this begs the question: How often should air conditioning filters be changed?

Generally speaking, you’ll want to change your air filters out every 90 days, or every 3 months. If you have pets or allergies, you may want to change out your air filters even more regularly, as often as every 45 days, or every 1 ½ months. Of course, there are situations where you may need to change your air filters even sooner.

Here are 5 additional signs that it may be time to change out your air filters:

1. You’ve noticed decreased airflow from your vents.

One of the most common indicators that it’s time for you to change out your air filters is limited airflow coming through your vents. 

A simple way to check for airflow is by simply holding up your hand to one of your vents. If there seems to be less airflow than usual, there’s a strong chance that clogged air filters could be slowing down the flow of air through your heating and air conditioning system.

How can you resolve this issue? It’s as simple as installing new air filters throughout your home. However, if you change out your air filters and continue to notice limited airflow, learn more about why your system may not be working by reading this article.

2. You’re having more allergy troubles than usual.

If you’re finding yourself sneezing a bit more than usual, it may be time to take a look at your air filters. As noted, when you have allergies, it’s a good idea to change out your air filters even more regularly—generally, twice as often as folks without allergies. 

Air filters are responsible for trapping dust, pollen, pet dander, and more. If your air filters are clogged, however, the remaining particles will stay in the air instead. This can lead to increased allergy issues, not to mention lower indoor air quality. 

Step one is to ensure that you replace your air filters. With that said, step two is to consider installing additional means for improving the indoor air quality of your home. If you or a loved one suffers from allergies, an air purifier or UV-C light may help to further reduce contaminants in the air of your home. 

3. There’s dust coming from your vents.

In line with increased allergy issues, a noticeable increase of dust in your home may indicate that it’s time to replace your air filters. For instance, if you spot dust coming out of your air vents, or more dust than usual on household furniture near the vents, you may have clogged air filters.

Rather than allowing dust to continue to fill your home, or your air vents for that matter, replacing your air filters is a simple fix. Plus, it isn’t too costly, especially if you are capable of installing the replacement air filters yourself. 

Pro Tip: Replacing your air filters isn’t the only way to ensure that your home is dust free and your HVAC system is offering great indoor air quality. Find out more about How to Clean an HVAC System.

4. Your energy bills are higher than normal. 

There is a multitude of reasons why your energy bills could be increasing, several of which could be attributed to your air conditioning system. For example, an older HVAC system will require more energy to run. However, in many cases, an increase in your energy bills may be as simple as a dirty air filter.

The reality is that, when your air filters are dirty, your system has to work harder to pump air through those clogged filters. As a result, your system can overheat. Sometimes, it may even go as far as to shut off completely. 

Instead of letting your energy bills continue to rise, and losing out on energy-efficiency, swap out your dirty air filters for new ones. If that doesn’t reduce your energy bills, check out these 10 Simple Air Conditioning Tips to Save Energy

5. Your AC unit is hotter than usual. 

In order to keep your energy bill reasonably priced, you’ll want to ensure that your air conditioning unit is running as normal. One red flag that your system is overworking is an overheating AC unit. When your system overheats, you may notice your system working less effectively or not working at all.

A great way to prevent this from happening is by replacing your air filters. When you replace your air filters, you make it easier for your system to function as it should, prevent it from overheating unnecessarily, and lengthen the life of your system.
