Deal4parts Gets Ready for Summer: Essential Tips for Checking and Maintaining Home Air Conditioners

As the summer season approaches, we are increasingly eager to ensure that we are comfortable and cozy in our homes. And one of the most important tools that helps us achieve this is air conditioning. However, before we plunge into the hot season, it’s worth taking into account the preparation of our air conditioners for operation.

In this article, we will take a closer look at the process of preparing and maintaining air conditioners at home. We will reveal the main steps that should be taken before the start of the summer season to ensure efficient operation of the air conditioner and a comfortable indoor environment. From understanding how an air conditioner works to the importance of regular maintenance, we will make sure that your air conditioner is working at full capacity throughout the summer.

Understanding how air conditioners work

When summer arrives, air conditioners become an integral part of our daily lives, providing a comfortable indoor temperature. In order to use your air conditioner efficiently and prepare it for the season, it is important to understand how it works and its main components.

Air conditioners work on the basis of a cooling cycle known as the evaporation and condensation cycle. They use a compressor to create high pressure and vaporize the refrigerant liquid into steam, which takes place in the outdoor unit. This evaporation occurs in an enhanced heat exchange with the surrounding air, which removes heat from the room. The refrigerant liquid is then returned to the compressor, where it is compressed again to create high pressure and temperature. This process continues in a cyclical fashion, ensuring that the air in the room is constantly cooled.

Analysis of the main components of an air conditioner and their functions

The main components of an air conditioner include the compressor, condenser, steam expansion valve, and evaporator. 

  • compressor: It is responsible for compressing the refrigerant liquid, which starts the cooling cycle.
  • condenser: This is where the gas condenses into liquid, releasing heat from the room.
  • vapor expansion valve: Controls the flow of refrigerant liquid in the indoor unit, allowing it to evaporate and cool the air.
  • evaporator: It is responsible for evaporating the refrigerant and removing heat from the room.

Understanding the workings and components of an air conditioner helps ensure that it operates efficiently and is properly maintained.

Checking the operation of the air conditioner

Before the hot season arrives, it’s important to make sure your air conditioner is ready to work at full capacity.

Instructions for checking your air conditioner before the season:

  • Checking the outdoor unit. Make sure that the outdoor unit of the air conditioner is not blocked by any objects such as branches or debris. Make sure that there is enough free space around it to allow the hot air to be discharged.
  • Checking the indoor unit. Turn on the air conditioner and check whether the air flows normally from the indoor unit. Check whether all operating modes such as cooling, heating, ventilation, etc. are working.
  • Temperature check. Check whether the air conditioner is delivering air at the proper temperature. Make sure that the temperature setting is in accordance with the settings.
  • Preliminary maintenance. If you haven’t had your air conditioner serviced in the last year, consider a preliminary maintenance check to check the condition of the system and the parts of the appliance.

Check the presence and condition of the filters

  • Filter Location: Find the location of the filters in your air conditioner. They are usually located inside the indoor unit.
  • Checking the condition of the filters: Remove the filters and inspect them for dirt, dust, and other contaminants. If the filters are very dirty, they can be cleaned or replaced with new ones.
  • Replacing the filters: If the filters are dirty, replace them with new ones according to the air conditioner manufacturer’s instructions. Clean filters provide better indoor air quality and improve the performance of the air conditioner.

Checking your air conditioner before the season and cleaning or replacing the filters will help ensure that your air conditioner runs efficiently and smoothly throughout the summer.

Cleaning and changing the filters

Clean filters are a key element in ensuring that your air conditioner runs efficiently and provides a healthy indoor environment. 

Steps to clean and replace the filters:

  • Shut down the air conditioner: Before you begin cleaning or replacing the filters, make sure the air conditioner is turned off and disconnected from the power supply.
  • Access the filters: The location of the filters may vary depending on the air conditioner model. Usually, they can be accessed on the front of the indoor unit.
  • Remove the filters: Carefully remove the filters from their mounts. The filters may be made of metal or plastic and may be reusable or disposable.
  • Clean the filters: If the filters are reusable, they can be cleaned of dust and dirt by vacuuming or rinsing them under warm water. For particularly dirty filters, you can use a mild detergent solution.
  • Replacing the filters: If the filters are disposable or are too dirty, they should be replaced with new ones. Refer to the air conditioner manufacturer’s instructions for replacing the filters.
  • Replace the filters: After cleaning or replacing the filters, replace them and make sure they are properly locked.

Effect of clean filters on air conditioner efficiency and indoor air quality

Clean filters play a critical role in the operation of your air conditioner. They help to keep the system free of dust, dirt, and other contaminants that can interfere with the proper operation of the air conditioner. In addition, clean filters provide better indoor air quality because they keep dust, allergens, and other harmful particles out.

Regularly cleaning or replacing the filters not only improves the efficiency of your air conditioner, but also contributes to a healthier and more comfortable indoor environment.

Checking the air conditioner ventilation system

The ventilation system is an important component of the air conditioner that ensures air circulation in the room. Before the summer season, it is important to check its condition and ensure smooth operation. Here are some steps to check the ventilation system:

Check the vents and ducts for dirt:

  1. Inspect the vents and ducts to make sure they are not blocked.
  2. Use a light and a mirror to identify any dirt or obstructions in the ducts.

To remove contaminants from the ventilation system:

  1. Use a vacuum cleaner with an attachment to clean dust and dirt from the vents and ducts.
  2. For deeper cleaning, you can use special tools for cleaning ducts.

Checking and adjusting the temperature settings

Proper temperature settings help to ensure comfortable use of the air conditioner and energy savings. Here are some tips:

Importance of the optimal temperature for comfortable use of the air conditioner:

  1. Set the temperature to a level that is comfortable for you, taking into account the outdoor climate and the characteristics of your room.
  2. Avoid overheating or overcooling the room to prevent excessive energy consumption.

How to set and check the temperature settings to save energy:

  1. Use the energy saving modes if available on your air conditioner.
  2. Consider installing a programmable thermostat to automatically adjust the room temperature based on the time of day and your schedule.


Proper preparation and maintenance of air conditioners before the summer season play a key role in ensuring their comfort and efficiency. Checking the ventilation system, cleaning and replacing filters, and adjusting temperature settings not only improves indoor air quality but also helps to save energy. In addition, regular scheduled maintenance ensures a long service life of the air conditioner and avoids unforeseen breakdowns. Remember that properly preparing your air conditioner for summer is an investment in your family’s comfort and health.
