4 Common Problems With Ducted Air Conditioning Systems

Ducted air conditioning systems are popular for homeowners and businesses on the Sunshine Coast, providing effective climate control across multiple rooms. However, these systems are not immune to issues like any complex machinery. Regular maintenance can help, but understanding common problems and their solutions is key to long-term efficiency and comfort. In this blog post, we’ll explore four frequent issues with ducted air conditioning systems and how to address them.

Air filters are critical in maintaining clean air circulation and system efficiency. When clogged with dust and debris, they restrict airflow, forcing the system to work harder and consume more energy. This can lead to increased wear and tear and reduced air quality indoors.

Key Indicators:

• Weak airflow from vents.
• Higher energy bills.
• Dusty or musty indoor air.

Solutions:

• Check and clean filters every three months.
• Schedule professional servicing for deep cleaning.
• For improved air quality, consider upgrading to high-efficiency particulate air (HEPA) filters.

Regular filter maintenance improves efficiency and prolongs the life of your system.

Damaged ductwork is a common yet often overlooked problem in ducted systems. Leaks or poorly insulated ducts can lead to significant air loss, making it difficult to maintain desired temperatures and driving up energy costs.

Signs to Watch For:

• Uneven temperature distribution in rooms.
• Increased energy consumption.
• Audible whistling or hissing noises.

Solutions:

• Conduct routine inspections of ductwork.
• Seal leaks promptly using professional-grade solutions.
• Replace damaged sections to prevent long-term inefficiencies.

Efficient ductwork ensures your air conditioning system operates effectively and saves you money in the long run.

A faulty thermostat can disrupt the system’s functionality, leading to discomfort and inefficiencies. This is often a result of outdated technology or calibration errors.

Symptoms of Thermostat Issues:

• Rooms too hot or cold despite settings.
• The system cycles on and off irregularly.
• Unresponsive or blank thermostat display.

Solutions:

• Replace old thermostats with modern, programmable options.
• Regularly calibrate the device to ensure accurate temperature readings.
• Consult a professional to address connectivity issues in smart thermostats.

A well-maintained thermostat keeps your system running efficiently and ensures consistent comfort across your space.

Refrigerant is essential for cooling performance. A leak diminishes the system’s ability to cool effectively and, if left unchecked, can damage the environment and the system itself.

Signs of a Refrigerant Leak:

• Cooling performance drops despite the system running.
• Ice buildup on coils or lines.
• Hissing sounds near the outdoor unit.

Solutions:

• Engage a licensed technician to detect and seal leaks.
• Recharge the system using the correct refrigerant type.
• Schedule regular maintenance to prevent future leaks.

Addressing refrigerant issues promptly ensures optimal system performance and extends the unit's lifespan.
