According to the EPA, Americans spend a majority of their time indoors, 90% in fact. However, most do not realize that indoor pollutants can be two to five times higher inside than outside.

That is why keeping your AC filter up to date with regular changes and proper maintenance is crucial. Your AC filter helps to keep pollutants to a minimum, which keeps you and your family safe. How do you know when to change the filter? 

Don’t worry; we have got the 5 signs you need to look out for, so keep reading! 

1. Electric Bill Increase

Florida summers average around 88 to 90 degrees, so you can expect your electricity bill to be slightly higher in the summer months. With that being said, if you see a higher than average bill on your monthly statement, it could be a sign that you need to change your filter. 

A dirty AC filter makes the unit work harder to get the house cool. That’s why regular HVAC maintenance is so important, so if you notice a spike, it might be time to contact a professional. 

2. Allergies 

Indoor air quality can often be more polluted than outdoor, but your AC filter helps reduce the pollutants by filtering the air before it gets into your home. However, if you have a dirty AC filter, all of that build-up will get pushed into your home, and that could cause issues like allergy flare-ups.

If you’re experiencing a sudden onset of stuffy noses, sneezing, etc., you might need to change your AC filter. Additionally, there are air purification devices that an HVAC professional can install in your home to increase your air quality. 

3. AC Overheating

If you notice that your AC unit’s back is pushing out warm or hot air, a dirty AC filter is most likely the culprit. When the filter is dirty, the unit has trouble getting cool air past the filter’s build-up. Eventually, if the AC filter is not cleaned, the unit will break. 

Changing the filter regularly will help increase the lifespan of your AC unit. If you don’t keep up with scheduled maintenance, it will cost you repairs and service calls. 

4. Dust Build-Up 

One of the simplest ways to tell if it is time to change your AC filter is dust. If the filter is dirty, you will see dust gathering on the vents and around any nearby furniture. Another way to test the filter is the white sheet method.

If you place a sheet in front of the vent for an hour, it should be clear of dust and debris when you check the sheet. However, if you see dust and color change on the sheet, the filter needs a change. 

5. No Cold Air

If your AC unit is running, but the air isn’t cool, it might be time for a filter change. When the filter is full, it prevents the cold air from being pushed through the vents and into the home. 

That being said, no cool air could be a sign of another more serious problem with your unit. So, if the air is still not cool after the AC filter has been changed, you should call for service on your unit.
