Keeping your air filter clean is a crucial part of aircon maintenance. The air filter traps dust, dirt, and other particles, keeping them from circulating in the air. When the filter becomes clogged, it hinders the unit’s efficiency, causing it to work harder and use more energy.

It’s important to clean or replace the air filter regularly to ensure that your aircon unit is working at its best. How often you should clean or replace the filter depends on some factors, such as how often you use your aircon and the level of air pollution in your area. As a general rule, cleaning or replacing the filter every 1-3 months is recommended.

Cleaning or changing your air filter regularly can make your aircon work better, use less energy, and make the air in your house cleaner.

2. Keep the Coils Clean

As time passes, dirt and debris can accumulate on the coils, causing the aircon unit to struggle to cool the air. This can increase energy bills and cause the unit to malfunction earlier than expected.

It’s important to schedule regular aircon maintenance services to clean the coils. During these services, a professional technician will clean the coils and remove any dirt or debris that has accumulated on them. Keeping the area around your aircon unit clean and debris-free is essential. This helps to stop dirt and dust from getting blown onto the coils, which can affect how well your aircon works.

You can easily keep the coils clean by following a few simple steps. For example, you can use a soft brush to remove dirt or debris on the coils. Also, use a vacuum cleaner with a soft brush attachment to clear dirt and dust from the coils.

3. Check the Condenser Coil

Maintaining the condenser coil of your aircon unit is essential for keeping it working and extending its lifespan. The condenser coil releases heat from the aircon unit, allowing it to cool the air effectively. If the coil gets dirty or damaged, your aircon unit may have to work harder and use more energy, resulting in higher energy bills and early breakdowns.

To keep the condenser coil clean, it’s important to schedule regular aircon maintenance services. During these services, a professional technician will clean the coil and remove any dirt or debris that has accumulated on it. The technician may also check if the coil has any damage, such as rust or cracks, and fix it to prevent bigger problems in the future.

There are simple ways you can take to keep the condenser coil clean. For example, you can use a soft brush to gently clear any dirt or debris that has accumulated on the coil. You can clean the coil using a garden hose, be careful not to apply too much pressure that could damage the coil.

Keeping the condenser coil clean can improve its performance, reduce energy consumption, and extend its life.

4. Check the Refrigerant Level

Refrigerant is the lifeblood of your AC system and is extremely important in the cooling process. Your air conditioner needs enough refrigerant to cool your space properly. If it doesn’t have enough refrigerant, it won’t work well and could harm your AC system over time.

Before you start working on your AC unit, turn it off and wait a few minutes to let it cool down. Next, locate the refrigerant lines that run from your air conditioner’s outdoor unit to the indoor unit.

Using a refrigerant gauge, check the current refrigerant level in your AC system. If it’s below the recommended level, then it’s time to refill it. Make sure to use the appropriate type of refrigerant for your AC unit, which you can find in the manufacturer’s guide.

Now, refill the refrigerant by connecting a refrigerant canister to your AC unit and following the instructions. It’s important not to overfill your AC system as it could cause damage.

5. Clean the Drain Line

Let’s understand how a clogged drain line can impact your aircon’s performance. The drain line is responsible for removing excess moisture from your air conditioner. When it gets clogged, the moisture can build up and cause water to overflow, leading to water damage and even mold growth. A clogged drain line can also strain your aircon system, making it harder to cool your space and potentially causing damage in the long run.

So, how can you clean your aircon’s drain line? Turn off your aircon and locate the drain line, usually a PVC pipe that runs from your aircon unit to the outside of your home.

Next, remove the drain line and use a wet/dry vacuum to extract any obstructions or accumulation that are obstructing it. You can also use a mixture of water and vinegar to help dissolve any blockages.

After cleaning, make sure to run some water through the drain line to flush out any remaining debris. Finally, reattach the drain line to your aircon unit and turn it back on.

Cleaning your aircon’s drain line can help prevent water damage, mold growth, and system failure, helping to extend the life of your unit.

6. Inspect the Thermostat

The thermostat is the brain of your aircon system and it controls the temperature and humidity level in your space. A faulty thermostat can cause your aircon to work, leading to higher energy bills and shortening the life of your unit.

How can you check your thermostat and ensure that it’s functioning? First, turn off your aircon and remove the cover of your thermostat. Check the wiring and make sure that all the connections are secure and in good condition. You can also use a multimeter to check the voltage and continuity of the wires.

Next, check the calibration of your thermostat. Use a thermometer to measure the room’s temperature and compare it to the temperature displayed on the thermostat. You may need to recalibrate your thermostat or replace it if there’s a significant difference.

If you need to replace your thermostat, choose a model compatible with your aircon system and has the features you need. Follow the manufacturer’s instructions carefully to install and set up your new thermostat.

7. Check the Electrical Components

Faulty electrical components can cause your aircon to malfunction and cause damage to your unit. To keep your air conditioner running its best, it needs electrical components like the capacitor, relay switch, and fan motor. These parts all work together to ensure your aircon stays in tip-top shape.

So, how can you inspect and maintain these electrical components? Turn off your aircon and locate the electrical panel. Open the panel and visually inspect the wires and connections for any signs of damage or wear. Check that all the connections are secure and tight.

Next, inspect the capacitor, relay switch, and fan motor. When you’re inspecting your air conditioner’s thermostat, keep an eye out for damage or wear, like cracks or burnt wires. If you’re not sure, you can use a tool called a multimeter to test the voltage and continuity of these parts.

If you notice any issues with the electrical components, it’s best to call a professional aircon technician to repair or replace them. It’s crucial to avoid DIY repairs when it comes to electrical components, as it could be risky and cause further damage to your unit.

8. Lubricate the Motor

Why is lubricating the motor so important? The motor is the heart of your aircon unit, and it needs to be well-oiled to function correctly. Without proper lubrication, the motor’s components can start to wear down, leading to increased friction, heat, and noise. This can cause your aircon to become less efficient, which can lead to higher energy bills and even a shorter lifespan for your unit.

Lubricating the motor is a relatively simple task you can do yourself with just a few basic tools. First, turn off the power to your aircon unit and wait for it to cool down completely. Locate the motor and remove the protective cover. Next, use a clean cloth to wipe away any dirt or debris from the motor’s components and check for any signs of damage.

Once you’ve cleaned the motor, it’s time to lubricate it. Choose a high-quality lubricant designed explicitly for aircon motors and apply a few drops to each motor’s moving parts. Be careful not to over-lubricate, as this can cause excess oil to build up and attract dust and dirt.

Finally, replace the protective cover and turn the power back on. Voila! You’ve lubricated your aircon motor, helping to ensure that it runs smoothly for many years.

9. Clean the Fan Blades

When fan blades get clogged up with dust, dirt, and debris, they must work harder to circulate the air. This means that your aircon has to use more energy to keep your room cool, which can add up over time. Also, a fan that’s working overtime can put more strain on other parts of your aircon, leading to potential breakdowns and repairs.

So, how can you keep your fan blades clean? Well, the good news is that it’s actually pretty simple. First, make sure you turn off your aircon before you start cleaning. Then, gently wipe down the blades with a damp cloth or sponge. If a lot of dirt and grime is built up, you might need to use a mild detergent or cleaning solution to help break it down.

Once you’ve cleaned the blades, dry them off completely before turning your aircon back on. You don’t want any excess moisture to cause rust or damage your unit. And remember, it’s a good idea to clean your fan blades. Aim for once every few months or so, depending on how frequently you use your aircon and how dusty your environment is.


10. Provide Proper Ventilation

Proper ventilation can have a big impact on the efficiency of your air conditioning unit. When an air conditioner is running, it produces a lot of heat. Without good ventilation, this heat can build up and cause the unit to work harder than it needs to. This leads to higher energy bills and can cause the unit to wear out faster, shortening its lifespan. So, how can you provide proper ventilation for your air conditioner? Here are a few tips:

  • Keep the outdoor unit clear: Make sure there are no obstacles around the outdoor unit of your air conditioner. This means trimming any bushes or plants that may block the unit’s airflow.
  • Keep vents clear: Make sure that furniture, curtains, or other objects do not block the vents in your home. Blocked vents can restrict airflow and make it harder for your unit to cool your home.
  • Use ceiling fans: Ceiling fans can circulate air throughout your home, making it easier for your air conditioner to cool your space.

11. Use a Programmable Thermostat

What are the benefits of using a programmable thermostat? It allows you to set different temperatures for different times of the day. This means you can keep your home cool when you’re there and save energy (and money!) when you’re not. Plus, it eliminates the need for constant manual adjustments, which can put unnecessary wear and tear on your AC unit.

But how do you choose and install a programmable thermostat? Make sure you choose one that’s compatible with your current HVAC system. Then, consider your desired features, such as WiFi connectivity or voice control. Once you have your new thermostat, turn off the power to your HVAC system, and remove the old thermostat. Lastly, connect the wires to your new one according to the manufacturer’s instructions.

12. Protect the Unit from the Elements

Weather conditions can have a big impact on the lifespan of your air conditioner. Extreme temperatures, heavy rain, and high winds can all cause damage to your unit over time. Here are some suggestions on how to protect your air conditioner from the elements:

  • Cover the unit: A cover can help protect your air conditioner from elements like rain, snow, and debris. When choosing a cover for your air conditioning unit, make sure it’s made for that purpose. Using covers not specifically made for AC units can trap moisture inside, harming your AC system.
  • Trim nearby trees and bushes: Make sure that no trees or bushes are too close to your air conditioner. Strong winds can cause branches to fall and damage your unit, while leaves and debris can clog the unit’s fins and reduce airflow.
  • Install a shade: If your air conditioner is in direct sunlight for much of the day, consider installing a shade to help protect it from the heat. This can reduce the workload on your unit, which can extend its lifespan.

13. Hire a Professional
