Reasons for Ducted Reverse-Cycle Air Conditioning System Inefficiencies

Posted on

When it comes to staying comfortable year-round, Australian homeowners have a wide selection of heating and cooling options to choose from. One of these options is ducted reverse-cycle air conditioning systems. 

Ducted air conditioning systems with reverse-cycle technology allow people to heat and cool their homes using the same equipment. In summer, they produce cool air – just like standard cooling-only units. In winter, they serve as heat pumps, delivering warmth to your indoor living space.

The heated or cooled air from ducted reverse-cycle units is distributed throughout the home via ductwork – a network of hidden conduits that deliver conditioned air to the rooms of your house.

When sized and installed correctly, your ducted reverse-cycle air conditioner will efficiently cool and heat your home. However, problems can arise down the road, resulting in heating and cooling inefficiencies.

Read along to learn about the various problems that cause ducted reverse-cycle AC systems to stop working efficiently.

Ductwork leakage

Duct leaks occur when conditioned air travelling through damaged or worn-out ducts escapes before it reaches the supply air vents installed in different rooms of a house. These leaks cause your ducted reverse-cycle air conditioner to work overtime to keep you cool or warm enough. The strain on your air conditioning system results in increased energy usage, which causes your domestic utility expenses to go up.

Leaky ducts will need to be sealed or replaced depending on their condition and age. 

Dirty ducts and vents

All parts of your ducted reverse-cycle air conditioner naturally become dirty over time. As a result, it's not uncommon for dust and dirt to accumulate inside your air ducts and vents.

When this happens, your air conditioning system may experience poor airflow, causing it to run harder and longer to keep your home cool or warm enough. Dirty air ducts and vents may also lead to poor indoor air quality, affecting the health of your family.  

Airflow issues caused by filthy vents and ducts can be addressed through a duct cleaning service.

Blocked air filters

Like other air conditioning systems, reverse-cycle ducted air conditioners use a filter to remove contaminants from the air. Over time, the filter becomes clogged with dirt and will need a replacement.

Failing to replace your AC system's filter regularly will cause the system to experience weak airflow. Consequently, your heating and cooling system will be forced to overwork to maintain comfortable room temperatures throughout the year.

Taking proper care of your ducted reverse-cycle air conditioner is essential to keeping it running smoothly and efficiently all year round. Contact an HVAC company to get a quote for your AC maintenance or repair needs.
