Check for these signs

Most people know that it’s important to change the air filter in their car regularly, but many don’t realize that the same is true for their home AC unit. Failing to change your AC filter can result in a host of problems, from decreased efficiency and higher energy bills to poor air quality and even structural damage.


If you’re not sure whether or not it’s time to change your AC filter, check for these signs:

The Air Conditioning Unit is Too Hot to Touch

If the air conditioning unit is too hot to touch, the filter is dirty and needs to be changed. A clogged filter forces the air conditioner to work harder, which makes it overheat. This will lead to more frequent repairs and may even shorten the unit's lifespan.


The AC Unit is Leaking Water

Another clear sign that it’s time to change your AC filter is if the unit starts leaking water. This usually happens when the filter is so clogged that air can’t flow properly, causing the unit to ice up. As the ice melts, it turns into water and leaks out.


Your Energy Bills are Higher than Usual

When the electricity bill starts to creep up, it’s often one of the first signs that something is wrong with the AC unit. A dirty filter can decrease the unit's efficiency by up to 15%, so if you notice a sudden spike in your energy bills, it’s a good idea to check the filter. A dirty air filter makes your AC unit work harder, which uses more energy and drives up your bill. Keeping your system well-maintained helps it run more efficiently, saving you a lot of money in the long run.


You’re Suffering More Allergy Attacks

Allergy sufferers should be particularly vigilant about changing their AC filters regularly. A dirty filter can cause a build-up of dust and other allergens in the air, which can trigger allergy attacks.


The air conditioning in your home can have either a positive or negative effect on your health. If you or someone in your family suffers from allergies, it’s especially important to ensure that the AC filter is clean. 


The Airflow from the Vents is Weak

If you notice that the airflow from your vents is weak, the air conditioner is working harder than usual. This can be caused by several things, but one of the most common is a dirty air filter. When the filter is clogged, it restricts airflow and makes the AC unit work harder. This not only decreases efficiency but can also lead to repairs.


There’s an Unusual Amount of Dust in Your Home

If you find an unusual amount of dust in your home, it could signify that the AC filter needs to be changed. A dirty filter can cause a build-up of dust and other allergens in the air, making your home feel stuffy and unlivable. Changing the filter is a good place to start if you notice a sudden increase in dust in your home.
