We all enjoy the breezy air of the air conditioner. But do we bother how to clean air conditioner the right way?

Generally, we do not. But if I say that a dirty AC can increase your electricity bills, would you still don’t care?

No, right? So, now when you are ready to clean your AC, make sure you know the right way of cleaning. 

How To Clean Air Conditioner Right Way

Here we will give you step-by-step guidance that will let you know how you can clean your AC.

First, we will start with the outdoor unit. And then, we will clean the indoor unit.

Cleaning The Outdoor Unit

Generally, the outdoor unit faces more dust and dirt in comparison to the indoor unit. So, you may need to put some extra effort in that.

Components you need

  • Gloves to save your hands from dirt.
  • Vacuum cleaner.
  • Proper screwdriver
  • No-rinse coil cleaner

Step 1: Unplugging

In AC cleaning and the cleaning process of any of the electrical appliances, you should first turn the switch off and unplug the machine.

So, here also, you should do the same.

Step 2: Remove the Grill

To remove the grill, you need a proper screwdriver. Before removing the grille, you have to remove the top panel. 

The top panel will also have screws. You have to remove them and pull the board out. 

Ensure that you keep the screws at a secured place as you will need them again to fix your machine again.

Now, after removing the top panel, you have to remove the screws of the grille. It generally consists of four screws.

Now discharge the grille and keep it aside. You will also get a front panel or filter after removing the grille.

Keep the grille and front panel aside.

Step 3: Cleaning The Debris off the Filter

In this section, you have to notice whether your AC model has a filter or not.

If you have a filter, the cleaning process will be easy, as the filter will prevent all the dirt from entering deep.

If there is a filter, remove that and clean it with normal water. Or you can use a wet or dry vacuum cleaner.

Step 4: Cleaning the Inside Area

After removing the filter, you will enter the inside part. If there is no filter, you will see the inside part after removing the grille and front panel itself. 

You can clean this section with the help of a vacuum cleaner. Try to vacuum every nook and corner to remove all the debris altogether.

Step 5: Cleaning the Fins and Coil

These two components are really delicate, so you may need to measure some safety. To clean this part, you have to use the no-rinse-coil-cleaner.

It will keep the electronic parts safe. You have to spray the no-rinse-cleanser in a zigzag direction. The spray will evaporate automatically and clean the parts.

Step 6: Cleaning the Outer Parts

Clean the parts you have removed, like the upper panel and grille. To clean them you can use regular water.

After the cleaning, leave them to dry.

Also, clean the other outer areas with water soaked cloth. Make sure to drench the water properly.

Also, clean the area around your outdoor AC unit. This will give the unit fresh airflow.

Step 7: Reassembling

When the separated parts are completely dried, reassemble them one by one. And now you are done enjoying the excellent air conditioning.

Cleaning The Indoor Unit

In this section, you will know how to clean the indoor unit of the AC. But before starting anything, make sure your AC unit gets enough light.

This will help to see the inner parts. 

Components you need

  • Soft brush.
  • No-rinse coil cleaner.

Step 1: Opening the Blower Unit

Again make sure that you remove the plug before plunging it into the cleaning process.

After you have ensured there is no power supply, now use a proper ladder or stool or chair to reach your AC.

Now remove the blower unit and keep it aside.

Step 2: Removing the Dust Filter

Once you open the blower unit, you will see dust filters right in front of you. Now remove them carefully and clean them under running tap water.

They are very easy to clean. You can use a soft brush as well. Now after cleaning, let them dry properly.

Step 3: Cleaning the Evaporator Coils

When you open the dust filters, you will notice a small door. Now you have to open that using the correct type of screwdriver.

After opening the door, you will see the evaporator coil. This is a really delicate part, so if you think that you do not trust yourself to use a cloth or brush to remove the debris, you can use the no-rinse-coil cleanse.

Using the no-rinse-coil cleaner is the best way to do it. These cleansers are readily available in any online store. 

Step 4: Washing the AC Drain Tray

Cleaning the drain tray is not that tough. You can clean it with the help of hot water and liquid detergent solution.

If you see tough stains on it, you can clean it with a mixture of 50% of water and 50% of bleach.

Step 5: Reassembling

Make sure that all the parts that you have rinsed are totally dried up. Now you can assemble them right the exact way you opened them.

Close the condenser coil door. Place the duct filters the right way. 

Close the blower unit. And you are good to go.

After you assemble them all, do not forget to run your AC for sometimes at the highest temperature.


Not cleaning your AC correctly can give you unwanted headaches. For example-

  • You may not get precise airflow.
  • The inner parts may need more power to produce proper air.
  • This can lead to an increment in your electricity bills.

Therefore, never skip the cleaning part of your AC.

Following these steps makes cleaning your air conditioner easier and enjoying the best cooling every time.
