How to clean air conditioner at home simply without calling a technician

Air conditioner cleaning cycle

The number of times the air conditioner needs to be cleaned periodically will depend on the environment and frequency of use during the year, specifically as follows:

For households: About 3 - 4 months/time (if opened and used every day) or 6 months/time (if used 3 - 4 days/week).

For companies and restaurants: About 2 - 3 months depending on the environment with more or less dust.

For businesses, factories, plants, and manufacturing plants: Clean monthly because the machine operates continuously at high frequency.

How to clean air conditioner at home simply without calling a technician

Before cleaning the air conditioner, you need to prepare:

Booster pump: This is a high-pressure water pump used to spray and clean the metal slots on the hot and cold coils. Just plug one end of the hose into a basin of water, and press the button on the other end to spray water whenever needed. You can use a glass sprayer or a watering can instead.

Plastic bag: Air conditioner cleaning services often use a metal trough or a dirty water bag as long as the evaporator and can be fixed to the evaporator. You can use a large plastic bag or make a raincoat into a large bag so that it can contain dirty water during the rinsing process.

Other items: Screwdriver; clean water; dishwashing liquid or detergent to clean the evaporator; clean cloth or plastic bag to prevent water from splashing on the circuit boards.

How to clean air conditioner at home:

Step 1: Turn off the air conditioner

To ensure safety during cleaning the air conditioner, please disconnect the power source connected to the air conditioner.

Step 2: Clean the condenser

First, remove the fan, open the air conditioner cover from bottom to top and take out the dust filter. Use a screwdriver to remove the screws that secure the case to the evaporator. Then, clean up the dust.

Use a cleaning bag to cover the entire body of the machine. Next, use an air conditioner cleaning solution to clean the parts in the condenser such as the shock cage fan blades, air filter and other parts.

Step 3: Clean the condenser

Remove the protective cover on the front of the condenser and use a spray nozzle to wash the protective layer. Next, clean the fan blades and dusty corners inside.

After spraying and cleaning the condenser components, use a dry cloth to wipe them clean. Do not spray water directly into the circuit board area, as this can easily cause damage.

Step 4: Check the air conditioner gas

Use a specialized gas meter to check the air conditioner gas, see if the pipe is leaking or if the air conditioner is running out of gas. If this happens, contact a reputable store to fix it promptly.

Step 5: Reassemble the parts into the air conditioner

Make sure the condenser and evaporator parts are clean and dry before reassembling. Reverse the steps for disassembly.

For the condenser: Carefully install the dust filter in its original position to avoid tearing the mesh. Next, install the fan and cover the air conditioner from top to bottom. Use a screwdriver to tighten the screws on the body of the machine.

For the condenser: Reinstall the protective cover on the front so that the prongs match up.

Step 6: Check and operate the air conditioner

Turn on the circuit breaker for the air conditioner to operate. You have completed the air conditioner cleaning process when you see that the machine runs smoothly and does not show any unusual signs or strange noises.

With the simple way to clean the air conditioner at home above, you can clean the air conditioner yourself at home without needing a technician. Don't be lazy, if you don't want the air conditioner to be "broken" after a short time of use.
