Air Conditioner

The outdoor unit is the big box that lives outside. It is not the little box inside the house. If you can’t figure out which is which on your system, look for the large pipe that runs between them. If you still get confused, call a professional to help you (you don’t want to be fiddling around with this stuff yourself).

It’s important to know where the outdoor unit of your AC is because it usually needs some TLC. The outdoor unit is full of vital machinery like fans and coils, and it tends to attract dust, dirt, and leaves over time that can clog its parts up. You can take the help of professionals like ducted air conditioning Sydney contractors to clean the outdoor unit.

Turn off your AC

To clean your outdoor unit effectively and safely, you need to first turn off the power that allows the system to run. This is a good time for a quick review of electricity safety. It is best practice to turn off the power before beginning any project involving your ducted AC unit to avoid unwanted electrocution or shock.

  • Turn off the thermostat inside your house by pressing “off” on the touchpad or by moving your dial to “off.”
  • Find the breaker box outside of your home and flip the switch labeled “air conditioner” on and off a few times as if you’re turning it on and off, but do not let go at any point until you hear an audible click. The switch will now be turned in one direction and should remain there until you are finished cleaning your outdoor unit so that power does not accidentally get restored while working on it.
  • Wait 10 minutes after turning off your system before beginning work so that any residual electrical current can dissipate completely from within its electrical components inside of both units (this is an important safety measure).

Remove The Cover

To clean the outdoor unit of your ducted air conditioner you need to remove the cover (the top and sides). To do this, turn off the power to the unit at the mains or circuit breaker. Next, carefully remove the fasteners holding all four sides of the cover; then, take out each side and set it aside. A tip: use a ruler or piece of cardboard to rest the screws on so they don’t get lost. The fan blades are now exposed so be careful when handling them—they can cause serious injury if they are allowed to spin freely while uncaged.

Clean Fan Blades, Coils, And Fins

Use a soft brush to clean the fan blades. If they are extremely dirty, you can use a cloth dampened in warm water. Do NOT use any kind of solvent or cleaning agent on the fan blades.

Clean the coils and fins with a soft brush and a damp cloth. Again, you do not want to use any type of solvent or cleaning agent on these parts, as it can damage them.

Do not use a pressure washer to clean your air conditioner’s outdoor unit! A pressure washer can knock coils out of place and cause other damage that could cost you more in the long run than if you had just cleaned it by hand in the first place.

Wash The Drain Pan

Now that you’ve located and cleaned out the drain pan, it’s time to give it proper washing. Using warm soapy water, clean the surface of your drain pan to ensure it is free of any clogs or debris. Once you’ve washed the pan, rinse thoroughly with clean water and dry completely before reassembling your unit. While you’re washing, keep an eye out for any common materials that can clog your systems such as algae, hair, dead insects, and leaves.

Align And Tighten Fan Blades

Take a wrench, tighten the fan blades, and make sure they are in alignment and clean of debris. A fan blade that is misaligned or has debris on it can cause the unit to vibrate or make noise. We recommend you to call professionals like air conditioning Sydney for maintenance and cleaning of your ducted AC.

Final Words

The outdoor unit of your ducted air conditioner is durable, but it still needs to be cared for. After all, its main job is taking in the warm air from your home and releasing it outside. Along with this, the hot weather from outside can also blow dirt and debris into the coil fins.

Clean the outdoor unit of your ducted AC at least twice a year, preferably more often if you live in an area with a lot of dust or pollen. This will help it run better and last longer.

  1. Unquestionably believe that which you said. Your favorite justification appeared to be on the internet the easiest thing to be aware of. I say to you, I definitely get annoyed while people think about worries that they plainly don’t know about. You managed to hit the nail upon the top as well as defined out the whole thing without having side effect , people could take a signal. Will probably be back to get more. Thanks
