Blocked or dirty ducts can cause your air conditioning system to work harder than it should. This extra strain might lead to more frequent breakdowns and a shorter life span for the unit.

Dirt and debris build up in the ductwork, reducing airflow and forcing the air conditioner to use more energy. This not only harms your HVAC system but also increases your energy bills.

Regular cleaning of these ducts helps maintain good indoor air quality, keeping musty odours and allergens at bay. A professional ducted air conditioning service can efficiently clean out blockages, ensuring that cool, fresh air circulates freely throughout your home.

Keeping these passages clear is crucial for both the efficiency of your aircon and the health of those living in your house.

Inadequate supply ducts

Inadequate supply ducts can wreak havoc on your ducted air conditioning system. They restrict airflow, making it hard for the system to cool your home efficiently during hot summer months.

This not only leads to discomfort but can also cause the air conditioner to shut down due to overheating. Regular checks are crucial to ensure these ducts are clear and delivering air as intended.
