Your air conditioning unit is fundamental, especially during the cold months. It helps make your home comfortable and saves you money by reducing the use of your electric heater.

Many central air conditioning units operate trouble-free for years, but there are some common problems that you need to watch out for. One of the most common problems is an inefficient air conditioning filter.

If you see any dirty AC filter symptoms, don’t delay checking it out. An inefficient AC filter will only add to the strain your air conditioner is already working to do, which can shorten its lifespan.

1. Not Cooling Effectively

If your air conditioner isn’t cooling your home effectively, it’s likely because the air filter is dirty. A dirty filter can restrict air flow, making it harder for your AC to do its job. As a result, your AC will have to work harder to cool your home, leading to increased energy usage.

Additionally, it can cause your AC to freeze up, which can lead to costly repairs. If you notice these symptoms, it’s time to clean or replace your air filter.

2. Higher Energy Bills

If you’ve noticed your energy bills creeping up, one possible reason is a dirty AC filter. A clogged filter can make your AC work overtime, driving energy costs. This should be checked monthly and replaced or cleaned as needed.

If your filter is visibly dirty, it’s time for a replacement. But even if it doesn’t look dirty, it may still be clogged with dust and debris. A good rule of thumb is to replace your filter every three months.

Ignoring a dirty AC filter can lead to many problems, including a frozen evaporator coil, water damage, and reduced airflow. So if you’ve been procrastinating on changing your filter, now is the time to do it.

3. Dust and Debris Build-Up

One of the essential parts of your AC unit is the filter. It helps to trap dust and debris so that it does not enter your home. Over time, it can become clogged with dirt and dust, which can cause it to become less effective.

Ignoring them can lead to severe problems, such as a complete AC unit breakdown. To clean your AC filter, remove it from the unit and wash it with warm, soapy water. Be sure to let it dry completely before putting it back in place.

4. Strange Sounds

You may notice strange sounds coming from your unit. These sounds can include rattling, screeching, or whining. Dirty filters can also cause your unit to vibrate more than usual. If you notice any of these symptoms, it’s essential to clean your filter as soon as possible.

When the problem becomes worst, you need to consult a professional to lessen the risks of a dirty AC filter. If you want to have a clean AC, you need to consider HVAC system repair.
