When the temperatures soar during the Australian summer, your ducted air conditioning system can feel like a lifesaver. However, one common question arises: Is it better to leave ducted air con on continuously, or should you turn it off when not in use? The answer isn’t straightforward, as it depends on several factors, including energy efficiency, running costs, and system wear and tear. This blog explores the pros and cons of keeping your ducted air con running and offers practical tips for maximising its efficiency.
How Ducted Air Conditioning Systems Work
Ducted air conditioning systems are designed to provide consistent cooling or heating throughout your home by circulating cool air or warm air via a network of ducts. These systems feature an indoor unit located in the roof space and an outdoor unit that works together to regulate the temperature.
- The system uses refrigerant to extract heat from indoor air, delivering cooling performance during summer.
- During winter, reverse cycle functionality allows it to generate warm air, ensuring year-round comfort.
Modern ducted air conditioning systems often incorporate smart technology and energy-efficient features, allowing homeowners to optimise their electricity bills and reduce energy consumption.
Pros of Leaving Your Ducted Air Con On
1. Maintains a Consistent Internal Temperature
- By running your air conditioning system continuously, you prevent your home from overheating during hot weather or cooling excessively during colder periods.
- The system doesn’t need to work harder to bring the home to your desired temperature, which can prolong its lifespan.
2. Enhanced Comfort and Convenience
- You avoid the discomfort of walking into a stifling house during the summer months.
- For families with varying schedules, leaving the system on ensures the home remains comfortable for everyone.
3. Can Be Energy Efficient in Certain Scenarios
- Contrary to popular belief, running your ducted air conditioning at moderate settings throughout the day can sometimes be more energy efficient than frequently switching it on and off.
- Modern systems equipped with inverters adjust the compressor speed to maintain the set temperature, reducing the overall workload.
Cons of Leaving Your Ducted Air Con On
1. Increased Running Costs
- Running your air conditioning system 24/7 can significantly increase your electricity bill, particularly if the system isn’t optimised or maintained.
- During extreme hot days, the system must work harder to counter the heat, leading to higher energy consumption.
2. Wear and Tear on the System
- Continuous operation can accelerate wear on key components, such as the air filter and compressor, leading to more frequent repairs or replacements.
- Regular maintenance becomes even more critical to keep the system functioning efficiently.
3. Potential for Energy Waste
- If parts of your home are unoccupied, leaving the system on may waste energy. Systems without zoning capabilities may cool or heat unused areas unnecessarily.
When to Leave Your Ducted Air Con On
- Extreme Weather Conditions: During prolonged heatwaves or cold snaps, continuous operation can provide much-needed relief.
- Smart Technology Integration: Homes equipped with smart technology can automate temperature adjustments based on usage patterns, ensuring energy-efficient operation.
- Homes with Poor Insulation: If your home struggles to retain its internal temperature, leaving the system on can prevent drastic temperature fluctuations.
When to Turn Your Ducted Air Con Off
- Extended Periods Away: If your home will be unoccupied for most of the day, it’s best to turn the system off to save energy.
- Well-Insulated Homes: Homes with proper insulation can retain cool air or warm air for longer, reducing the need for continuous air conditioning.
Tips for Optimising Ducted Air Conditioning Use
1. Use the Thermostat Wisely
- Set the thermostat to “Auto” mode to allow the system to cycle on and off as needed.
- Adjust the temperature to a comfortable but efficient setting (e.g., 24°C in summer).
2. Insulate Your Home
- Seal doors and windows properly to prevent heat infiltration or escape.
- Keep blinds closed during the hottest parts of the day to block direct sunlight.
3. Perform Regular Maintenance
- Clean or replace the air filter every few months to maintain optimal airflow and air quality.
- Schedule annual servicing with a professional to ensure the system is running efficiently.
4. Invest in Zoning
- If your system allows, use zoning to direct cooling or heating to occupied rooms, saving energy in unused spaces.
Balancing Comfort and Costs with Your Ducted Air Con
The decision to leave your ducted air conditioning on continuously depends on your specific needs, home layout, and energy goals. While the convenience and comfort of a consistently cooled or heated home are undeniable, it’s essential to weigh the running costs and potential wear on your system. By implementing smart usage practices, keeping up with maintenance, and optimising your system’s settings, you can enjoy the benefits of ducted air conditioning without breaking the bank.
