Why Preventive AC Maintenance is Important?

In order to have a good functioning of the air conditioning system, it is important to carry out a regular air conditioner repair program. Preventive maintenance adjusts air conditioners as well as reducing the level of pollutants in an air-conditioned environment, while also increasing the life of equipment and reducing energy consumption.

Some maintenance can be carried out by the owner, such as cleaning the air filters, which are easy to remove and clean. This cleaning can be done by running water and neutral soap. To replace the filters in the same way in the air conditioner it is essential that this part is completely clean and dry.

When the air filter exhibits obstruction due to the presence of impurities, it causes the airflow of the product to decrease, i.e. it decreases the air outlet speed of the air conditioner. This obstruction results in a decrease in the performance of the appliance, in the reduction of energy efficiency, in the freezing of the heat exchanger and consequent reduction of the life of the air conditioner.

It is important to point out that most of the existing flaws in air conditioners are due to a lack of preventive maintenance.


It is recommended that a more complete preventive air conditioner maintenance be carried out annually to guarantee an increase in the useful life of the product and thus the permanence of the guarantee.
