If you have the machine working good then there is no problem and the problems start when you have the dust and debris getting into your machine to cover the filter and the duct.
The duct and the filter brings in fresh air and if the dust, pollen and debris come into the room through the air conditioning machine then the people gets unwell and unfit. The most sensitive people will find that the pollens that come in makes them allergic.
The duct should therefore be free of the contaminants and need to regularly clean the duct and make arrangement for proper technicians to come over once in a month to look into the machine and check it and do the required maintenance work so that the machine performs in a satisfactory manner.
You will find the manual that can suggest why the machine works slow at certain times and so you must keep the filters clean so that the air remains clean and you can keep the coil that is used to cool or heat the air that is going to come out of the machine free of any clutter.

These things and a regular maintenance from your technicians will keep the machine performing properly for the machine to run properly for a long time to come. The technicians taking care of your system will also advice you on the use of the machine and can guide you to a smooth running of the machine.
