How To Service Your Ducted AC System At Home

During the hot summer months, a well-functioning air conditioning system is crucial for maintaining a comfortable indoor environment. If you have a ducted AC system in your home, regular maintenance and service are essential to ensure optimal performance and energy efficiency. While it’s always recommended to have a professional technician service your AC system, there are a few tasks you can perform yourself to keep it in good condition. In this article, we will guide you through some steps on how to service your ducted AC system at home.

Safety First

Before starting any maintenance work on your AC system, it’s important to prioritize safety. Ensure that the power to the AC system is completely shut off from the electrical panel to avoid any accidental shocks or injuries. Also, make sure you have the necessary tools and equipment for the job, including gloves, safety glasses, and a mask to protect yourself from dust and debris. 

If you don’t have the necessary tools and equipment, then you should consider taking the help of professionals such as air conditioning Sydney experts. They have all kinds of necessary tools and equipment.

Clean or Replace Air Filters

One of the simplest and most effective maintenance tasks you can do is to clean or replace the air filters in your ducted AC system. Clogged or dirty filters restrict airflow, reducing the efficiency of your system and potentially leading to costly repairs. Locate the air filter panel, usually found near the return air grille or in the air handler unit, and carefully remove the filters. If they are washable, follow the manufacturer’s instructions to clean them. If they are disposable, replace them with new ones. This should be done at least every three months, or more frequently if you have pets or allergies.

Check and Clean the Outdoor Unit

The outdoor unit of your AC system plays a crucial role in heat exchange. Over time, it can accumulate dirt, leaves, and debris, obstructing airflow and reducing the system’s efficiency. Inspect the outdoor unit and remove any visible debris using a soft brush or a vacuum cleaner with a brush attachment. Be gentle to avoid damaging any delicate components. Trim any nearby plants or bushes to maintain a clear space of at least two feet around the unit for proper air circulation.

Clean the Evaporator and Condenser Coils

The coils in your AC system can become dirty and affect its performance. Locate the access panel to the evaporator coil, which is typically located in the air handler unit or ductwork. Use a soft brush or a fin comb to carefully remove any dust or debris from the coils. 

For the condenser coils, which are situated in the outdoor unit, you can use a garden hose to gently rinse away dirt and grime. Be cautious not to bend the delicate fins during cleaning. If the coils are excessively dirty, it may be best to contact a professional technician for a more thorough cleaning.

Inspect and Clean Ducts and Vents

While not directly related to the AC system itself, inspecting and cleaning your ducts and vents is crucial for maintaining good indoor air quality. Remove the vent covers and vacuum the vents to remove any dust or debris that may have accumulated. If you notice a significant buildup of dust or suspect mold growth, it’s advisable to contact professional duct cleaning service professionals such as ducted air conditioning Sydney professionals for a more comprehensive cleaning.

Check and Test the Thermostat

A malfunctioning thermostat can lead to temperature inconsistencies and inefficient operation of your AC system. Inspect the thermostat for any visible signs of damage or wear, such as loose wiring or corroded batteries. Replace the batteries if necessary and ensure the thermostat is clean and free from dust. Test the thermostat by adjusting the temperature settings and observing whether the AC system responds accordingly.

Reassemble and Restore Power

Once you have completed the necessary maintenance tasks, reassemble all the components, including the filters, access panels, and vent covers. Double-check that everything is securely in place before restoring power to your AC system. Turn on the power from the electrical panel and set the thermostat to the desired temperature. Listen for any unusual noises or vibrations and observe whether the system is functioning properly.

Monitor and Maintain Proper Refrigerant Levels

The refrigerant in your ducted AC system is responsible for cooling the air that is circulated throughout your home. Over time, refrigerant levels can decrease due to leaks or other issues, affecting the system’s cooling efficiency. Monitoring and maintaining proper refrigerant levels is an important part of servicing your AC system.

Wrap Up

Remember, while these steps can help you maintain your ducted AC system, it’s still essential to schedule professional maintenance at least once a year. A trained technician can thoroughly inspect and service your system, identify any potential issues, and ensure its optimal performance and longevity. Regular maintenance not only saves you money on energy bills but also helps prevent costly breakdowns during the hot summer months.
