5 Common Signs That You Need to Change Your AC Filter

With all of the maintenance tasks that homeowners have to worry about, it can be easy to forget small details such as your AC filter. However, making sure that your AC always has a clean filter is extremely important for the health of your HVAC system as well as the cleanliness of the air that you and your family breathe.

If you’re unsure how to tell whether or not your AC filter needs to be changed, you’re not alone. Here are the 5 most common signs that it’s time to replace your AC filter.

  1. Your energy bill is spiking.

An unexpected increase in your energy bill is never a good sign. Though this could be caused by a variety of factors, one of the most common being a dirty AC filter.

When dust and dirt accumulate within your AC’s filter and cooling coils, your AC system will have to work harder to achieve the temperature set on your thermostat, therefore causing your energy bill to spike. A clean filter can improve the efficiency of your system, bringing your bill back down to a normal range for your usage.

  1. Your allergies are acting up. 

If you or another family member are experiencing increased allergy symptoms, it may not just be allergy season. Clogged and dirty AC filters can lead to pollutants being circulated throughout your home’s ventilation system, causing allergies or other lung conditions like asthma to flare up.

  1. You haven’t scheduled AC maintenance in a while.

Most homeowners know that regular HVAC tuneups are extremely important to extend the lifespan of your AC and furnace systems and make sure they’re functioning as they should. If you haven’t had an AC expert check your system in a while, there’s a good chance that your filter and other working parts of your unit might need cleaning or tuning up.

  1. Dust is building up near the vents.

Keep an eye on your home’s vents. Are you noticing an unusual amount of dust buildup? This is a surefire sign that your AC filter needs changing.

  1. Your AC unit is running hot.

It’s important to know what your AC system feels and sounds like when running properly. If your AC system is making strange noises, that could be the sign of a moving part coming loose or a similar malfunction; however, if your unit feels hotter than usual, it probably means that the filter is clogged, forcing the machine to work excessively hard.
