Despite its simplicity, an air conditioner’s filter can have a significant impact on the HVAC system’s efficiency and the quality of the air in your home.
This article highlights 5 signs that tell you it’s time to change your custom air filter.
Before we proceed, if you do not have an air filter in your home, you can contact the nearest residential air filter supplier to you, or order online from Custom Filters Direct.

1. You Can’t Recall When You Last Did It
Most experts recommend changing your house air filter every one to six months, with the average being every three months.
If you can’t recall when you last replaced it, you are likely past due.
2. You’re Experiencing More Allergic Reactions
Dirty or clogged custom air filters are bad news for people with respiratory diseases.
When it comes to changing air filters, allergy patients need to be very vigilant. The air filter collects dust, pollen, and pet dander.
When the filter becomes saturated with pollutants, the pollutants are blown out and circulated around your home.
Therefore, you’ll be subjected to more frequent allergy episodes or asthma attacks.
The air conditioner in your home can have a beneficial or bad impact on your health. Instead of making the air inside your home worse, use the air conditioner to make it even better.
Maintain a clean custom size air filter and consider installing an air purifier. Symptoms should start to fade quite quickly.
3. The Air Vents Are Dusty
Finding dust on surfaces and furniture near the vents is another sign you need to change your custom air filter.
Compare these surfaces to other nearby surfaces. It’s a solid sign that your air filter needs to be replaced if the surfaces closest to the vents are dustier than others.
Also, if you fail the “white sheet test” then it is time to change your ac filter.
The “white sheet test” is a creative approach to determine if the air filter is unclean.
For at least one hour, hang a clean white sheet roughly 5 inches away from one of the vents. If the sheet turns grey, the air filter is dirty. The dirtier the filter, the greyer the sheet.
4. Your Air Conditioner Isn’t Very Cold.
When the rear of the unit gets too hot, it’s a sure sign that your AC filter needs to be replaced.
If the filter is too dirty, you may even feel warm air flowing out of the back of the device. When the filter is clogged, the air conditioner needs to work harder to keep the house cool.
This will result in more frequent AC repairs and, as a result, a shorter unit lifespan.
Reduce the load by changing the AC filter regularly.
Also, if your air conditioner is sending out air that isn’t as chilly as it should be, replace the air filter.
It may be working overtime due to a clogged filter. If that doesn’t work, you’ll have to seek professional assistance. They may completely inspect your air conditioner to determine whether it needs to be repaired or replaced.
5. Your Energy Bills Have Increased
It may be time to change your custom air filter if your energy bills are higher than usual and you haven’t altered anything about your AC usage.
A partially blocked filter might make your air conditioner work harder, resulting in higher energy expenditures.
Even if it appears to be in good condition, you should replace it to see if it helps with the costs.
Conclusion
To maximize the efficiency of your air conditioner, do right by it.
How? Pay attention to its functionality (i.e the air it produces, the sounds it makes, etc) and conduct routine cleanings around it.
That way, you can notice any slight difference in its efficiency.
