The frequency at which you should service your air conditioning system depends on several factors, including the age of the system, how often it is used, and the manufacturer's recommendations.
Generally, it is recommended that you have your air conditioning system serviced at least once a year.
During an air conditioning service an engineer will inspect and clean various components of the system, such as the filters, coils, and condenser, and ensure that everything is working properly. Regular maintenance can help to extend the lifespan of your air conditioning system, improve its efficiency, and prevent potential breakdowns.
If you notice any issues with your air conditioning system, such as decreased performance or strange noises, it's best to have it serviced as soon as possible. Additionally, if you have an older system, you may want to consider having it serviced more frequently to ensure that it is operating safely and efficiently.
