6 Signs That Your Ducted Air Conditioning System Needs Repair

A ducted air conditioning system is a great way to regulate and circulate cooling and heating throughout your home. However, as with any piece of machinery or technology that sees heavy use, it will eventually require maintenance to keep it in tip-top shape. Recognizing and addressing the signs that your ducted air conditioner needs to be serviced can help reduce costly repairs and extend its lifespan.

Uneven Airflow

If you have noticed that some rooms in your house are not getting cool enough or that there is a drastic difference between room temperatures, then this could be a sign that your ducts need to be cleaned. It is likely that dirt, dust or mould has got into the ducts and is blocking the flow of air to and from your air conditioning unit. The best way to solve this is to get in a professional to clean your ducts before it becomes too bad.

Unusual Sounds

Any unusual noises from your ducted air conditioner are usually a warning that it’s time for maintenance. This could include squealing, banging or whistling sounds. These types of noises can indicate a number of problems within your system, such as a slipping belt or a loose component.

Ducts

Over the years, it is not uncommon for ductwork to become damaged or blocked by vermin. Possums and rats often chew their way through ducts in search of shelter, especially in winter. As they crawl around the ducts, they leave behind faeces and urine which can then be spread through your home’s airflow. This type of contamination can not only be unpleasant to live with, but it also has a negative effect on the efficiency and hygiene of your ducted air conditioner.

Poor Airflow

If you notice that your ducted air conditioner is struggling to provide adequate cooling or heat, then it is likely due to poor zoning gate functionality. A professional should be called in to fix this problem, and they will ensure that the zoning gates are working correctly and allowing for proper airflow.

Dirty Coils

It is important to regularly change the filter in your ducted air conditioning system, as it can quickly become dirty. Over time the evaporator and condenser coils in your ducted air conditioning system can become covered with dust, dirt or even pollen, which can then reduce the efficiency of the air conditioner. It is also possible that the coils are suffering from a leak in the copper tubing. This is a serious issue and should be fixed immediately.

Gas or Refrigerant Leaks

The compressor is like the heart of your ducted air conditioning system. If it starts having issues then this can have a domino effect across the whole system, causing higher energy bills and increasing wear and tear on other components. A leaking compressor can also be dangerous and needs to be repaired immediately by a professional.

A ducted air conditioning service includes a complete inspection of your entire system, from the indoor and outdoor units to the ductwork and vents. This includes testing the power of the unit and zone motors as well as checking the electrical connections and ensuring that there are no air leakages. A full service will also include the cleaning of the evaporator and condenser fans, flushing out the drain lines and identifying any areas where you could improve the ductwork.
