Air conditioning systems are vital to keeping our homes comfortable, especially during the summer months. But did you know that they are also among the most energy-consuming appliances in a household?

    To ensure air conditioners operate efficiently and maintain a cool, comfortable environment, it’s essential to follow some maintenance best practices. Here are seven practical tips for keeping your air conditioner at its peak performance, allowing you to enjoy a cooler home without compromising on energy efficiency.

    Regular Cleaning and Filter Replacement

    Air conditioners work by drawing in warm air, cooling it and then circulating it back into the room. During this process, the air passes through filters designed to remove dust and impurities. Over time, these filters can become clogged with dirt and debris, hindering airflow and making your air conditioner work harder than necessary.

    Tip 1: Clean or replace your air conditioner’s filters regularly, following the manufacturer’s guidelines. A clean filter ensures better indoor air quality and keeps your AC running efficiently.

    Keep the Condenser Unit Clean

    The condenser unit, usually located outside your home, is responsible for dissipating the heat collected from inside. It’s exposed to the elements and can accumulate dirt, leaves and debris, which can obstruct the airflow and impact the air conditioner’s performance.

    Tip 2: Keep the area around the condenser unit clean and free from debris. You can gently hose down the unit to remove dirt and dust. Note that there should be at least two feet of clearance around it to ensure proper airflow.

    Check for Leaks and Duct Issues

    Leaky ducts or damaged insulation can result in cooled air escaping before it reaches your living space. This not only reduces your air conditioner’s efficiency but also increases your energy bills.

    Tip 3: Inspect your ducts for leaks and damage. Seal any gaps or hire a professional to repair ductwork as needed.

    Maintain the Thermostat

    Your thermostat serves as the control centre for your air conditioner. If it’s not working correctly or is outdated, it can lead to inefficient cooling.

    Tip 4: Consider upgrading to a programmable thermostat. This allows you to set temperature schedules, optimising cooling when you need it most. Regularly check and calibrate your thermostat to ensure accurate temperature readings.

    Professional Maintenance

    While many aspects of air conditioner maintenance can be handled by homeowners, it’s essential to schedule regular professional inspections.

    Tip 5: Contact a qualified HVAC technician for an annual check-up. They can inspect, clean and maintain the internal components of your air conditioner, ensuring it continues to run at peak efficiency.

    Shade and Insulation

    Proper shading and insulation in your home can have a significant impact on your air conditioner’s efficiency. Inadequate insulation and direct sunlight exposure can make your air conditioner work harder to maintain a cool temperature.

    Tip 6: Install blinds or curtains to block out direct sunlight during the hottest parts of the day. Adequate insulation in your home’s walls and attic can help maintain a consistent temperature, reducing the workload on your air conditioner.

    Avoid Overcooling

    Setting your air conditioner to the lowest possible temperature may seem like a quick way to cool down, but it can lead to inefficiency and higher energy bills.

    Tip 7: Set your thermostat to a comfortable but not excessively low temperature. Every degree you raise it can result in significant energy savings.


    Maintaining your air conditioner’s efficiency isn’t just about reducing your energy bills but also about ensuring a comfortable and cool living space. By following our tips, you can keep your air conditioner running efficiently, extend its lifespan and enjoy a more eco-friendly and cost-effective way to stay cool during the summer months.

    Take the time to care for your air conditioner, and it will reward you with reliable performance and reduced energy costs.
