Cleaning the external unit
During the maintenance of air conditioning systems, great importance should also be given to external blocks that are clogged as intensively as internal. The only difference is that this service is carried out no more than twice during the year even with the constant use of the air conditioner. The same vacuum cleaner will help to clean the external block. However, it should be remembered that the vacuum cleaner must have sufficient power to remove dirt from heat exchange radiators and external filters.
