Last Updated on December 16, 2023 by Kimberly Crawford

Do you know your physical health can be greatly affected by the quality of air that you inhale in your home? If you are someone who has been suffering lately from unexplained allergic reactions, irritation of the eyes, nose, or throat, vomiting, dizziness, headaches, or nausea, it is time to get your AC filter checked.

Your dirty or clogged AC filter is to blame for such health hazards. But the good news is that there are some very simple yet effective ways to detect the problems associated with your AC filter, and you can easily fix those. The hardest part seems to be remembering to look for these signs.

How to Know if Your AC Filter is Having Problems

Here are some signs that can help you detect if your Air Conditioning system is having a problem. If unattended, most of these signs will lead to major problems and will result in high maintenance costs for your AC.

A rise in Electricity Bill

Have you noticed a higher than usual power bill in recent times? If yes, then it may be due to the lack of your Air Filter maintenance. When your AC is working harder to keep a balanced temperature in your home, more energy is consumed.

As a result, you need to pay for the excess energy that is being wasted. There is a simple solution to this problem.

If you check your AC filter more often, keep it clean and replace it regularly, you will never face this problem whatsoever. We recommend using Custom Filters Direct to buy AC filers online. They have most AC filters sizes available on their website.

Your AC Unit is Overheating

A dirty and clogged AC filter will force the AC filtration system to work overtime because it needs more energy to push through the same amount of air. As a result, your AC unit becomes hot to the touch.

If you notice this sort of problem, you need to check the filter right away. Increased overheating may lead to some serious problems, even AC breakdowns. So, the bottom line is that you must check for a clogged or dirty filter if your AC unit feels hot to the touch. Simply replacing the filter is the only solution here.

The Filter Looks Dirty or Clogged

Another sign of your AC filter having problems is the filter looking either clogged or dirty. That’s the most common visual indication that your filter needs to be replaced immediately. You need to replace your AC filter as soon as possible if you find out your filter is filled with dust, looks damaged, or seems to be clogged.

A clogged or dirty filter can not only restrict airflow but also reduce energy efficiency. It is also responsible for poor quality indoor air supply. As a result, the Air conditioning system fails to provide the right temperature for your home. This type of problem can be easily solvable by cleaning the filter from time to time.

It Takes Much Longer to Cool or Heat Your Home

If you notice your home is not warming or cooling off as easily as it used to be, it indicates that your AC filter is having some trouble functioning. A non-functioning filter usually takes a longer time to heat or cool rooms. You can replace the filter or make sure it’s clean if you want to solve this sort of problem.

You Notice a Strange Smell

Another indication of your filter having a problem is the smell. If you notice a burning smell from your AC unit, this can be a sign that your AC filter is clogged or dirty. So, next time you notice the smell,don’t just simply ignore it.


These signs will help you detect any sort of problem that your AC filter must be facing. Look for these signs carefully. If you detect any of these problems, just replace the filter as soon as possible.

Besides, you can custom ac filters from various residential air filter suppliers to make sure that your air filter needs less maintenance. You can choose from different ac filter sizes. If you need any assistance regarding the problem detection associated with your AC filter, feel free to seek help from a local professional.
