Tell-tale Signs That You Need to Change Your Air Conditioning Filters

If your energy bills have been creeping up, it might be time to change your air conditioning filters. Dirty filters can make your AC system work harder, using more energy and driving up costs.

Here are a few tell-tale signs that it’s time for an aircon filter change:

1. Your Energy Bills Have Increased

If you’ve noticed a steady increase in your energy bills, then it could be due to dirty air filters. When AC filters are clogged, they restrict airflow and make the system work harder to cool your home. This uses more energy and drives up costs.

2. Your Home Is Dustier Than Usual

If you’ve been dusting more frequently than usual, then it could be a sign that your aircon filter is not clean. When filters are clogged, they can’t trap dust and other particles as effectively. This allows more dust to circulate through your home, making it appear dirtier.

3. Your AC System Is Running More Frequently

If your AC system seems to be running more often than usual, then it could be due to dirty filters. When filters are clogged, this causes the system to run more frequently in an effort to maintain a comfortable temperature.

4. Your AC System Isn’t Cooling Your Home As Well

If you’ve noticed that your AC system isn’t cooling your home as effectively as it used to, thendirty filters could be to blame. Dirty and overly clogged filters make it difficult for the system to maintain a comfortable temperature.

How Often Should You Change Air Conditioning Filters in Your Home?

It’s important to change your home’s aircon filter regularly to keep the air quality high and prevent expensive repairs. But how often should you really be changing it?

Ideally, you should be changing your air conditioner’s filter every 3 to 6 months. However, this can vary depending on a few factors, such as the type of aircon filter you’re using, the frequency of AC use and the number of people living in your household.

If you have a smaller home or live by yourself, you may be able to get away with changing your filter every 4 to 6 months. On the other hand, if you have a larger home or live with multiple people, you may need to change your filter every 3 to 4 months.

What Happens If You Don’t Change the AC Filter?

Regularly cleaning or changing your air filter is one of the most important things you can do to keep your AC running smoothly and efficiently. Not only will it help keep your health in check, but it will also save you money on energy costs in the long run. 

If you don’t change your aircon filter, a few things could happen. Your air conditioner could overwork itself trying to cool your home and eventually break down. A dirty filter also puts extra strain on your AC unit, making it work less efficiently and costing you more money in the long run.

Another potential issue is that your indoor air quality could suffer. A dirty air conditioner filter can’t trap all the pollutants in your home, which means they will recirculate through your HVAC system and back into the air you breathe. This can cause respiratory problems, exacerbating conditions like allergies and asthma.

So, changing your aircon filter is important for both your air conditioner’s longevity and your family’s health. Make sure to check the filter monthly and replace it as needed. And if you have pets or someone in your home with allergies, you may need to change the filter more often.

Effective Tips When Changing Your AC Filter

As the weather warms up, many of us begin to think about our air conditioners and how to keep them running efficiently. One key part of AC maintenance is changing the filter regularly. 

Here are a few tips to help you change your aircon filter effectively:
  1. Check your owner’s manual or the manufacturer’s website for the type of filter you need. It is important to get the right one for your unit.
  2. Take the old filter out and hold it up to the light. If you can’t see through it, it’s time for a new one.
  3. Clean the area around the filter before installing the new one. This will help ensure that air can flow freely into the unit.
  4. Make sure the filter is seated properly on its slot and that the arrow on the filter is pointing in the right direction.
  5. Check your AC unit a few hours after changing the filter to make sure it’s working properly.
  6. Use disposable aircon filters like AirClean Filters instead of the traditional panel filters to avoid mould growth and keep your air clean.
