8 Ways To Improve Your Air Conditioner’s Energy Efficiency
When temperatures rise, the air conditioner becomes the most-used appliance in many homes. But without proper care, it can also be one of the most expensive to run. Whether it’s a ducted system cooling a family home or a split system in a small apartment, efficiency plays a major role in how much energy your AC uses and how high your power bills go.
In a town where air conditioning is essential for comfort, improving system efficiency isn’t just about comfort—it’s about sustainability and savings. Fortunately, there are several ways to keep your system running efficiently without compromising performance. From regular servicing to small tweaks around the home, each strategy contributes to a more energy-conscious cooling setup.
Here’s a practical guide to improving your air conditioning efficiency and reducing unnecessary running costs.
1. Clean or Replace Filters Regularly to Avoid System Strain
Air filters play a critical role in how well your system performs. When filters are clogged with dust and debris, airflow becomes restricted. This forces the unit to work harder, using more electricity and straining components unnecessarily.
Regularly cleaning or replacing filters can:
- Improve air circulation and system performance
- Reduce the strain on fans and motors
- Help maintain indoor air quality
- Prevent dust from accumulating on evaporator coils
During high-use periods, filters should be checked every 1–2 months. More frequent cleaning may be necessary in homes with pets or allergy concerns.
2. Seal Air Leaks Around Windows & Doors to Stop Cool Air Escaping
Even the most advanced air conditioner can't maintain a comfortable temperature if cooled air is constantly escaping. Small gaps around windows and doors allow conditioned air to leak out while letting warm outdoor air in, forcing your AC to run longer and harder.
Areas to inspect and seal include:
- Window frames and sills
- Door thresholds and weather stripping
- Gaps around vents and skylights
- Crawl space access panels
Using caulking, insulation strips, or foam seals can make a noticeable difference in keeping cool air where it belongs.
3. Install a Smart Thermostat to Automate and Optimise Temperature Control
Smart thermostats give you more control over your cooling system by allowing temperature scheduling and remote operation. These devices adjust temperatures automatically based on your routines, reducing waste when the house is empty.
Key features of smart thermostats include:
- Programmable schedules based on daily routines
- Remote access via smartphone apps
- Integration with other smart home systems
- Learning capabilities that adapt to preferences
These systems work in conjunction with efficient air conditioning, ensuring that energy is used only when needed.
4. Schedule Regular Servicing to Keep Components Running Efficiently
Routine maintenance is one of the most effective ways to maximise the efficiency of any air conditioning system. Professional servicing includes inspections, cleaning, and testing of all key components.
Typical tasks in a professional service include:
- Cleaning evaporator and condenser coils
- Checking refrigerant levels and topping up if needed
- Inspecting electrical components and controls
- Flushing condensate drains to prevent blockages
A well-maintained system uses less energy, breaks down less frequently, and operates safely throughout the year. For more on this, read about the benefits of regular air conditioning servicing.
5. Keep Outdoor Units Clear of Debris to Maintain Proper Airflow
The outdoor condenser unit plays a key role in releasing heat from your home. When it’s blocked by leaves, dust, or debris, the unit can't expel heat effectively, which compromises system efficiency.
Maintenance tips for outdoor units:
- Trim shrubs and branches at least 50cm away
- Remove leaves, grass, and mulch from around the base
- Clean the fins using a soft brush or vacuum
- Ensure the unit sits level on a solid base
Proper airflow allows the condenser to function efficiently and prevents overheating.
6. Use Ceiling Fans to Support AC Performance Without Overuse
Ceiling fans are a simple yet highly effective way to enhance cooling efficiency. By circulating the cooled air throughout a room, fans reduce the need to lower the thermostat.
How fans can reduce cooling demand:
- Distribute air evenly to prevent hot spots
- Create a wind-chill effect for comfort
- Allow the thermostat to be set 1–2°C higher
- Reduce reliance on the AC during mild days
Fans should rotate counter-clockwise in summer to push cool air downward for maximum effect.
7. Upgrade to an Energy-Efficient System if Your Unit is Over 10 Years Old
Older air conditioners often lack the energy-saving technologies found in modern systems. As systems age, components wear down, performance drops, and running costs climb. If your unit is over a decade old, an upgrade might be the most cost-effective move.
When upgrading, consider:
- Energy ratings (look for high star ratings)
- Inverter technology for variable speed control
- Zoned ducted systems for selective cooling
- Modern split systems with eco modes
Upgrading can reduce energy consumption by 30–50% while delivering better performance and quieter operation.
8. Block Sunlight & Heat During the Day with Curtains or Blinds
External heat load is one of the biggest factors increasing cooling demand. Direct sunlight streaming through windows raises indoor temperatures, especially in west—and north-facing rooms.
Simple ways to reduce heat gain include:
- Closing curtains or blinds during the day
- Installing reflective window films or awnings
- Using thermal-backed or blockout curtains
- Adding insulation to windows and roof spaces
Reducing heat entry means your air conditioner doesn’t have to work as hard to maintain a comfortable environment.
