Well-timed cleaning will help to avoid costly repairs of the air conditioner and to increase the effectiveness of its work. While the main cleaning should better be done by professionals, cleaning some parts of the conditioner is possible to be made by your own hands.
What will happen if not to clean the air conditioner in time?
- the filters will become black, the conditioner will start working with the noise and crackle
- because of malfunction of the drain pipe the device will bleed with water
- inside the device due to the moisture, bacteria will breed, the air conditioner will evolve bad smell
Cleaning the internal block of the central air conditioner
1. Changing the air filter
The air filter must be replaced. The new one can be purchased at the hardware store.
2. Turning off the air blower
Turn off the power of the blower. This can be done on the block itself or on the main panel. You may purchase a new detail for replacement at any nearby store that sells household goods. You should specify the size of the filter in advance in the operational manual of the device. Moreover, you can take the old part with you as a sample, that will allow to choose the detail for replacement properly.
- Change the filter.
3. Cleaning the ventilator box
Open and vacuum the ventilator box. If the motor ports need lubrication, apply a special (or universal WD-40) oil for motors.
- You should better clarify in the User’s Guide about the need to lubricate ports.
4. Removing the drain pipe
Remove the pipe for condensate and check whether there were algae. If the pipe is littered up, you can replace it or pour with the bleach solution (1 part to 16 parts of water).
Clean the drain pipe with the vacuum cleaner or a small brush.
6. Restarting the air conditioner
Connect the drain pipe back in and restart the device.
Cleaning the outdoor unit of the central air conditioner
1.Turning off the power
Turn off the power on the external unit of the air conditioner.
2. Cleaning the ventilator
Clean the ribbed surface of the ventilator using a vacuum cleaner with a soft brush. It is likely that in order to get a better access you have to unscrew the protective metal case from the wall.
Check whether there are weeds, leaves, and other trash inside that block the airflow. Remove extra foliage around the outdoor unit at the distance of about 60 cm.
Be careful when cleaning so as not to damage the fins. These parts get easily bent—if necessary, straighten them with a kitchen knife or a special comb.
3. Removing the air diffuser
Remove the air diffuser at the upper part of the air conditioner. Carefully, so as not to damage the wires, remove the air diffuser with the fan.
- •Wipe the fan with a damp cloth.
4. Lubricating ports
Check whether there is the need for lubricating ports. If yes, then drip in each of them per 5 drops of the oil for electric motors (you can use the universal one, for example, WD-40).
5. Washing the block
Lower the water hose into the empty block. With the moderate water pressure, rinse the inside of the fan impeller.
Assemble the device. Put the fan back into the block and screw the air diffuser.
7. Turning off the air conditioner
Turn off the room thermostat.
8. Turning on the power
Turn on the power and leave the air conditioner in the standby mode for 24 hours.
9. Restarting the air conditioner
Toggle the thermostat back and set the temperature. Wait 10 minutes.
10. Checking the correctness of the operations
Make sure the air conditioner works properly. To do this, check the insulation in the pipes that come out of the air compressor. One of the pipes must be cold, and the other must be quite heated. If not, you should consult a professional who will adjust the level of the coolant.
Cleaning the room air conditioner

Turn off the air conditioner from the mains.
2. Cleaning the outer part

3. Checking the drainage system
