Complete guide to cleaning and maintenance of domestic air conditioners

Air conditioners are essential for maintaining a cool and comfortable environment on hot summer days. However, to ensure optimal performance and prevent health problems related to air quality, it is essential to clean and maintain your air conditioner regularly. In this guide, we will take a step-by-step look at how to properly clean domestic air conditioners, including filters and outdoor units.

When to clean your air conditioner

First of all, it is important to plan when to perform these tasks in order to maximise their effectiveness. Here are some tips on when it is best to clean and maintain your air conditioner. The best time to clean the filters depends on the use of the air conditioner and environmental conditions. However, there are some general guidelines:

Before summer: Before the hot season arrives and you start using your air conditioner intensively, it is advisable to thoroughly clean the outdoor unit and filters.

During periods of intensive use of the air conditioner, such as summer, it is advisable to clean the filters at least once a month. This ensures that they are free of dust, dirt and allergens, maintaining a healthier environment inside your home.

At the end of the hot season, it is advisable to perform a more thorough cleaning of the filters because hot air tends to retain dust particles that settle on the filters of the indoor unit. We will see later how to wash the filters of dedicated products

Cleaning the air conditioner filters

Here's how to proceed:

1. Switch off the air conditioner: Before starting any cleaning operation, make sure that the air conditioner is completely switched off to avoid any accidents.
2. Locate the filters: Air conditioner filters are usually located behind the front panel of the indoor unit. Remove the panel to access the filters.
3. Remove the filters: Gently pull the filters out of their housing. Be sure to handle them with care to avoid damage.
4. Cleaning the filters: Use a vacuum cleaner with a brush attachment to remove dust and dirt from the filters. Once the dust has been removed, wash them with warm water and mild soap. Be sure to dry them completely before reinserting them into the unit.
5. Sanitising the filters: Once they are completely clean and dry, use a sanitiser that will sanitise the entire filter and make the air coming out of the indoor unit cleaner.
6. Replace the filters: reinsert the filters into the indoor unit, ensuring that they are correctly positioned. These filters usually have a single installation direction.

Electrostatic air conditioner filters

Some air conditioner models are equipped with rectangular filters called electrostatic filters, which are used to trap as many dust particles as possible in cases of allergies.

These filters should be replaced regularly depending on the use of the air conditioner, at least once per season to maintain high levels of efficiency.

Cleaning the outdoor unit of the air conditioner

The outdoor unit of the air conditioner is exposed to the elements and dust, so it is important to keep it clean to ensure efficient operation. Here's what to do:

1. Turn off the power: Before you start cleaning, make sure the power to the outdoor unit is turned off.
2. Remove debris: Use a vacuum cleaner or soft brush to remove leaves, debris and other residue that accumulates around the outdoor unit.
3. Clean the grilles: Check the grilles on the outdoor unit and remove any debris or obstructions that could compromise airflow. If possible, use an air compressor or compressed air canister to remove dust from inside the evaporator.
4. Checking the fans: Check the fans on the outdoor unit to ensure they are free of debris and rotating freely.
5. General hygiene: Ensure that the area around the outdoor unit is free of obstacles that could interfere with airflow, especially at the rear of the machine.

Conclusions

Regular cleaning and maintenance of domestic air conditioners is crucial to ensure efficient operation and good air quality inside the home. By following the steps outlined in this guide and maintaining a regular cleaning schedule, you can extend the life of your air conditioner and enjoy a cool, healthy environment all year round.
