9 Steps Involved In Maintenance Of Outdoor Unit Of Ducted AC

Ducted air conditioning systems are becoming increasingly popular in homes and businesses, especially in areas with extreme weather conditions. These systems require regular maintenance to keep them running at peak efficiency and to prevent breakdowns. One critical aspect of maintenance is taking care of the outdoor unit, which is responsible for heat exchange and cooling. In this article, we will discuss the essential steps involved in the maintenance of an outdoor unit of a ducted air conditioning system.

Step 1: Shut off the Power for AC Maintenance

Before beginning any maintenance or cleaning, it is crucial to turn off the power to the outdoor unit. The outdoor unit contains electrical components, which can be dangerous if not handled correctly. Locate the electrical panel that controls the power supply to the unit and switch it off. If you’re unsure about which breaker controls the outdoor unit, consult the owner’s manual or contact a licensed HVAC technician like ducted aircon Sydney professionals.

Step 2: Remove Debris and Clean the Unit for better maintenace

The outdoor unit of your ducted air conditioning system is exposed to the elements, which means it can collect dirt, leaves, and other debris. This debris can clog the air filters and reduce the efficiency of the unit. Begin by removing any debris from the surrounding area, including fallen leaves, grass clippings, and twigs. Next, use a garden hose to spray the unit gently, starting from the top and working your way down. Be careful not to use too much pressure as this can damage the fins and coils of the unit.

Step 3: Clean the Fins and Coils

Once the debris has been removed, it’s time to clean the fins and coils of the unit. The fins and coils are responsible for heat exchange, and they can become dirty and clogged, reducing the efficiency of the unit. Use a soft-bristled brush to gently clean the fins, being careful not to bend them. You can also use a commercial fin cleaning spray that is specifically designed for air conditioning systems. 

Spray the fins with the cleaning solution and let it sit for a few minutes before rinsing it off with a garden hose. If the coils are heavily soiled, consider hiring a professional HVAC technician to clean them.

Step 4: Check the Fan Blade

The fan blade is responsible for blowing air through the unit, and it can become unbalanced or damaged over time. Turn the fan blade by hand and listen for any unusual sounds or vibrations. If you notice any issues, contact a licensed HVAC technician to inspect and repair the fan blade.

Step 5: Inspect the Refrigerant Lines

The refrigerant lines are responsible for carrying the refrigerant that cools the air in the unit. Inspect the lines for any signs of wear or damage, such as cracks or leaks. If you notice any issues, contact a licensed HVAC technician to repair the lines.

Step 6: Check the Condensate Drain

The condensate drain is responsible for removing excess moisture from the unit. If the drain becomes clogged, it can cause water to accumulate inside the unit, which can lead to mold growth and other issues. Check the drain for any signs of clogging, such as standing water or moisture around the unit. If you notice any issues, contact a licensed HVAC technician to clear the drain.

Step 7: Check the Electrical Connections

The electrical connections are responsible for powering the unit and controlling its functions. Over time, these connections can become loose or damaged, leading to issues with the unit’s performance. Inspect the connections for any signs of wear or damage, such as frayed wires or loose connections. If you notice any issues, contact a licensed HVAC technician to repair the connections.

Step 8: Remove Obstructions Around The Unit
