7 Aircon Parts That Need Regular Maintenance - Keep Your Cool This Summer!

Keeping your air conditioner running smoothly and efficiently during hot summer days is essential for a comfortable and enjoyable home. However, the key to a well-functioning air conditioner is regular maintenance. In this blog post, we will take a look at 7 important parts of an air conditioner that need regular maintenance in order to keep your cool this summer!

The air filter

One of the most important parts of an air conditioning system is its air filter. This filter traps dust and other airborne particles can cause breathing difficulties, such as asthma and allergies. Regularly changing or cleaning your air filter will help to keep your air conditioner running efficiently, reduce the need for repairs, and improve air quality.

It’s best to check your air filter every month, and replace or clean it if necessary. To clean your air filter, you’ll need to remove it from the system, vacuum it using a soft brush attachment, and then rinse it with water. After cleaning, allow it to dry completely before putting it back in place.

Regular maintenance of your air filter will help ensure that your air conditioning system continues to run at peak efficiency, providing you with the cool comfort you deserve during the hot summer months.

The evaporator coils

Your air conditioner’s evaporator coils are an important part of its cooling system. They absorb heat from the air inside your home, cooling it down and sending it back out through the vents. The evaporator coils need to be regularly maintained in order to keep your air conditioning unit running efficiently. This includes cleaning and inspecting the coils for signs of dirt, rust, or other damage. Regular maintenance will also ensure that your evaporator coils are operating at peak efficiency and not leaking refrigerant or otherwise impeding the cooling process.

You should check for any signs of moisture buildup or mould growth around the evaporator coils. If left unchecked, this can cause damage to your air conditioning unit as well as create a health hazard. Taking the time to properly maintain your evaporator coils can save you money in the long run by helping your air conditioning unit operate at peak efficiency and avoiding costly repairs.

The condenser coils

The condenser coils of your air conditioner are located outside and serve to expel the heat taken in by the evaporator coils. To ensure your aircon runs at peak performance, it is important to keep the condenser coils clean. Regularly removing dirt, leaves, and other debris from around the condenser unit can help prevent the coils from becoming clogged and allow for greater airflow.

It is also recommended that you inspect the coils at least twice a year for signs of damage or wear and tear. If the coils are damaged, it could result in reduced cooling efficiency and higher energy bills.

The compressor

The compressor is a critical component of an air conditioner as it helps to pressurize and move the refrigerant throughout the system. It’s also responsible for maintaining the appropriate pressure and temperature in your air conditioning system. That’s why regular maintenance of the compressor is essential. You should check your compressor regularly for signs of wear, damage or other issues that can be caused by dust and dirt. Make sure to replace the oil filter and clean any dirt or debris that has built up on the components.

Additionally, inspect the fan blades and lubricate them if necessary. If you find any damage to the compressor, it is best to replace it right away as continued use can lead to further damage and costly repairs. By taking proper care of your air conditioner’s compressor, you can be sure your air conditioner will remain running optimally for years to come.

The air handler

The air handler, or fan coil unit, is the component of your air conditioner responsible for circulating air throughout your home. It’s important to regularly check the fan and blower motor, as well as the evaporator coil, and replace any worn or broken components. Make sure to also clean the filter to ensure it’s not blocked. This will help keep your air conditioning system running at its peak performance, while ensuring that your home is cool and comfortable.

Check the condensate line to make sure it’s not clogged and drains properly. If it needs to be replaced, hire a professional for the job. Regular maintenance of the air handler will help extend the life of your air conditioner and keep you cool all summer long!

The thermostat

The thermostat is an essential component of an air conditioning system and its role is to monitor the temperature in the house and adjust the fan speed and cooling level accordingly. It’s important to maintain your thermostat as any malfunctioning can lead to an uncomfortable home environment and costly repairs.

Regular maintenance includes testing for accuracy, cleaning, replacing batteries, and checking for proper wiring. Inspect the unit for signs of dust buildup, wear and tear, or any other damage that may affect its performance. Make sure to set the temperature correctly and replace the filter regularly to ensure optimal energy efficiency. Taking care of your thermostat can help extend its life expectancy and guarantee reliable performance.

The ductwork

The ductwork in your air conditioning system carries cooled air from the evaporator coil to all the rooms in your home. It’s important to regularly inspect and maintain the ductwork to ensure it is clean and free of dust, debris, and other contaminants that can reduce air flow and hinder performance. Look for cracks or holes in the ducts and make sure they are sealed properly.

If you notice any signs of damage, have a professional inspect and repair the ductwork as soon as possible. It’s also important to check for proper insulation and to make sure it is free of mould, mildew, and other allergens. Regular maintenance of your air conditioning ductwork can help keep your air conditioner running at its optimal level.


Air conditioners are essential during the summer months and require regular maintenance in order to work properly and efficiently. Taking the time to regularly inspect, clean, and repair the 7 main aircon parts will help ensure that your system runs optimally and you can stay cool all summer.

If you don’t feel comfortable completing any of these tasks yourself, contact a professional HVAC technician to get the job done right. With regular maintenance, your air conditioner will be ready to take on the summer heat!
