How to Unblock Air Conditioning Filters?

Breathing New Life into Your AC: A Guide to Unclogging Air Conditioning Filters

When the summer heat bears down, your air conditioning unit becomes your ultimate ally in creating a cool and comfortable haven no matter where in New Zealand you live. However, over time, even the most reliable AC can start to falter, leaving you with less-than-optimal cooling. Before you dial up a repair service, consider a simple solution: unclogging your air conditioning filters. In this blog, we’ll not only guide you through the process of cleaning or replacing your filters but also explore how a reboot can potentially resolve certain AC issues.

Our top tip before investigating the air filters?

It may sound arbitrary, but please try and reboot the A/C unit by turning the isolating switch off for 5 minutes; this will reset the unit and can actually fix some issues. The isolating switch can be found by the outdoor compressor.

The Importance of Air Conditioning Filters

Air conditioning filters play a critical role in maintaining the efficiency and longevity of your cooling system. These filters trap dust, dirt, pollen, and other particles, ensuring that the air you breathe is clean and free from allergens. However, when these filters become clogged, they hinder airflow, forcing your AC to work harder and potentially leading to reduced performance, higher energy bills, and even system breakdowns.

Step-by-Step Guide to Unclogging Filters

Cleaning or replacing your air conditioning filters is a straightforward process that can make a world of difference. Here’s a step-by-step guide to help you get started:

Step 1: Locate the Filters

Most air conditioning units have filters located inside the indoor unit. Refer to your AC’s manual if you’re unsure about their location.

Step 2: Turn Off the System

Before you start working on the filters, it’s crucial to turn off your AC system. 

Step 3: Remove the Filters

Gently remove the filters from their housing. Depending on your AC model, this might involve sliding them out or opening a panel.

Step 4: Assess the Condition

Examine the filters to determine the level of clogging. If they are visibly dirty or covered in dust, it’s time for a clean.

Step 5: Cleaning or Replacement

  • Cleaning: If your filters are reusable and lightly clogged, you can clean them by gently vacuuming off the dust or rinsing them with water. Make sure the filters are completely dry before reinserting them.
  • Replacement: If the filters are heavily clogged or damaged, it’s best to replace them with new ones. Refer to your AC’s manual for the appropriate filter size and type.

Step 6: Reinsert the Filters

Put the cleaned or new filters back into their housing, ensuring they are properly aligned and secure.

Step 7: Turn the System On

Now that your filters are clean or replaced, you can turn your AC system back on. Feel the difference in airflow and cooling efficiency as your AC benefits from the improved airflow.

The Role of Rebooting in AC Maintenance

Remember the isolating switch we mentioned earlier? As it turns out, a reboot can complement your filter-cleaning efforts. When you reboot your AC by turning off the isolating switch for about 5 minutes, you’re allowing the system to reset and recalibrate. This can address minor issues caused by factors like temporary electrical glitches.

Rebooting and Filter Unclogging: A Dynamic Duo

Combining filter unclogging with a system reboot can have a synergistic effect on your AC’s performance. Here’s how:

  • Enhanced Airflow: Clean filters coupled with a reboot ensure that your AC receives proper airflow, reducing strain on the system and improving its overall efficiency.
  • Resetting Sensors: A reboot can recalibrate sensors that regulate temperature and humidity, ensuring accurate readings and optimal comfort.
  • Minor Issue Resolution: Rebooting can fix minor issues that might arise due to clogged filters, such as reduced cooling capacity or irregular cycling.

In Conclusion 

Your air conditioning system deserves a little care and attention, especially when it comes to something as crucial as its filters. By following the steps outlined in this blog and coupling them with a system reboot, you can not only maintain your AC’s performance but also potentially resolve minor issues without the need for a call-out. A clean filter, combined with a refreshed system, will not only keep you cool but also extend the life of your air conditioning unit.
