It's different for both residential air conditioners and commercial air conditioners. The air conditioner at your house has to be serviced once after every 3 months. This is the best solution to keep it in its best shape. As far as the commercial air conditioner is concerned, servicing it once a month would be the right decision.This doesn't always have to be like that. You can tweak the schedule sometimes but remember not to delay more than two months.g longer to service your air conditioner will only result in the formation of several problems. Because of the dust, your air conditioner will have poor airflow. Not having your AC serviced can also hurt its functionality and performance.https://sibehcool.com/services/
